(80) For the fully variable valve actuation system of the independent oil drain valve controlled on the valve side, the phase limit module 2 and the mode selection module 22 can be cancelled. The first oil supply port 3a, the first drive port 3c, the second oil supply port 3e, the third oil supply port 3f and the fourth oil supply port 3g of the first control module all connect to the first oil supply module 6.

The valve actuation module 1 finishes opening and closing the valve by means of hydraulic actuation and spring reset.

(98) Take the six-cylinder internal combustion engine with the sequence of 1-5-3-6-2-4 as an example, the phase limit module 2 and the mode selection module 22 are designed. For the phase limit module 2 of the six-cylinder internal combustion engine with the sequence of 1-4-2-6-3-5, it is only necessary to adjust the opening angle of each oil port section of the phase limit module spindle 2n on the basis of the phase limit module 2 accordingly. Or for the internal combustion engine with the brake mode, it is necessary to change the connection object of the oil path between the phase limit module 2 and the mode selection module 22. For the internal combustion engine without the brake mode, it is only necessary to change the connection object of the oil path between the phase limit module 2 and the valve actuation module of each cylinder, but repeated work is not needed.

(105) According to the valve open/close requirement of the internal combustion engine under the brake mode, when the naturally aspirated internal combustion engine with the drain-for-drain &drain-for-supply brake mode needs to brake, the valve actuation system switches on the intake valve near the TDC and the engine vents the compressed air in the cylinder along the air intake duct, so as to reduce the power of the compressed air for the piston when the piston goes down; when the engine opens the exhaust valve at the BDC and sucks air into the cylinder from the exhaust duct, so as to increase the negative power of the compressed air of the piston when the piston goes up. When the turbocharged or naturally aspirated internal combustion engine with the supply-for-supply & brake-for-brake mode needs to brake, the valve actuation system opens the exhaust valve near the TDC and the engine vents the compressed air in the cylinder along the air intake duct, so as to reduce the power of the compressed air on the piston when the piston goes down; the engine opens the intake valve near the BDC and sucks air into the air cylinder via the intake duct, so as to increase the negative power of the compressed air for the piston when the piston goes up.

Meanwhile, the first oil port 27a of the switch valve assembly disconnects with the fifth oil port 27e of the switch valve assembly, the second oil port 27b of the switch valve assembly disconnects with the sixth oil port 27f of the switch valve assembly, and the third oil port 27c of the switch valve assembly disconnects with the seventh oil port 27g of the switch valve assembly, but the fourth oil port 27d of the switch valve assembly connects with the eighth oil port 27h of the switch valve assembly. Under the brake mode, the switch valve assembly spindle 27q rotates over a certain angle or moves to a certain distance axially, the first oil port 27a of the switch valve assembly connects with the fifth oil port 27e of the switch valve assembly, the second oil port 27b of the switch valve assembly connects with the sixth oil port 27f of the switch valve assembly, and the third oil port 27c of the switch valve assembly connects with the seventh oil port 27g of the switch valve assembly, but the fourth oil port 27d of the switch valve assembly disconnects with the eighth oil port 27h of the switch valve assembly.
(113) The switch valve assembly 27 may also adopt the independent switch valve structure, comprising the first switch valve 23, the 2nd switch valve 24, the third switch valve 25 and the fourth switch valve 26. The fifth oil port 27e of the switch valve assembly connects with the first oil port 23a of the first switch valve, the first oil port 27a of the switch valve assembly connects with the first oil port 23b of the first switch valve, and the sixth oil port 27f of the switch valve assembly connects with the first oil port 24a of the second switch valve.

(114) Please note that functions of the phase limit module 2 and the mode selection module 22 are independent in this case. The decision on setting the mode selection module 22 shall be made depending on the brake mode in the actual application, but there is no effect on the phase limit module 2 and other components of the system. The structure of the mode selection module 22 shall be selected according to different drive patterns of the mode selection module 22 and brake modes. For internal combustion engines with different numbers of cylinders, it is only necessary to increase or reduce the specific oil port section on the mode selection module 22 and the phase limit module, but it is unnecessary to change other oil port sections and other components of the system. According to different requirements for the flexibility of the valve, the speed of the internal combustion engine and the overall layout of the system, it is only necessary to change elements of the control module and oil delivery module, there is no effect on other parts of the system. For different ignition sequences of internal combustion engines, it is only necessary to adjust the opening angle of each oil port section of the phase limit module spindle 2n; or for an internal combustion engine with the brake mode, it is only necessary to change the connection object with the oil path between the phase limit module 2 and the mode selection module 22; or for an internal combustion engine without the brake mode, it is only necessary to change the connection object with the oil path between the phase limit module 2 and the valve actuation module of each cylinder. Therefore, through a simple adjustment only, the system is applicable for different engine types and has a wide range of applications. In the meantime, structures of the mode selection module 22 and the phase limit module 2 and oil port positions, etc. shall be adjusted according to the actual assembly requirements. Besides, various components of the system are connected via oil pipes, which meet the system layout requirement of application vehicle types.
(115) Take the fully variable valve actuation system of the non-independent oil drain valve controlled on the oil supply side of the naturally aspirated internal combustion engine with the sequence from one-cylinder to five-cylinder to three-cylinder to six-cylinder to two-cylinder to four-cylinder and the drain-for-drain & drain-for-supply brake mode as an example. For instance, the oil drain valve 9 is normally closed. When the first two-position three-way valve 19 is off, the oil supply port 19a of the first two-position three-way valve connects with the oil delivery port 19b of the first two-position three-way valve and the drive port 19c of the first two-position three-way valve is plugged. When the a second two-position three-way valve 21 is off, the oil supply port 21a of the second two-position three-way valve connects with the oil delivery port 21b of the second two-position three-way valve, and the drive port 21c of the second two-position three-way valve is plugged.
(116) Based on design characteristics of the system under this circumstance, the operation of the valve actuation module 1 is decided by the movement law of the first oil supply module 6, the second oil supply module 5 and the phase limit module 2, as well as the working status of the mode selection module 22, the first two-position three-way valve 19, the a second two-position three-way valve 21 and the oil drain valve 9. According to the working status of the mode selection module 22, the working process of the valve actuation module 1 can be divided into the drive mode and the brake mode. Its working process is stated below:
(117) (I) Drive Mode
(118) When the internal combustion engine stays in the drive mode as the power source, the mode selection module 22 is not actuated, the first drive oil supply port 22a of the mode selection module keeps connecting with the first drive port 22g of the mode selection module, and the oil control inlet 22r of the mode selection module keeps connecting with the oil control outlet 22s of the mode selection module, but the first drive port 2e of the phase limit module disconnects with the second oil supply port 2a of the phase limit module all the time. Therefore, the valve actuation module 1 can only work in the range limited by the movement law of the first oil supply module 6 and the phase limit module 2, and specific valve operation parameters are adjusted depending on the working status of the oil drain valve 9 and the first two-position three-way valve 19 in this range. Its working process is stated below:
(119) (1) When the Valve is Actuated: 0 C.A-240 C.A
(120) In this phase, the first drive port 2e of the phase limit module connects with the first oil supply port 2b of the phase limit module, but the first drive port 2e of the phase limit module disconnects with the second oil drain port 2d of the phase limit module. Under the drive mode, the valve actuation oil path is completely connected, i.e. the first oil supply port 2b of the phase limit module, the first drive port 2e of the phase limit module, the first drive oil supply port 22a of the mode selection module and the first drive port 22g of the mode selection module.
(121) (a) When the First Oil Supply Module 6 Supplies Oil: 0 C.A-120 C.A
(122) At that time, the first drive port 2e of the phase limit module connects with the first oil drain port 2c of the phase limit module. Under the drive mode, the first oil drain path is completely connected, i.e. the first drive port 22g of the mode selection module, the first drive oil supply port 22a of the mode selection module, the first drive port 2e of the phase limit module and the first oil drain port 2c of the phase limit module. The following events can be realized:
(123) a) The valve is opened: when the first oil supply module 6 enters the oil supply phase and the timing signal for valve actuation is received, both the first two-position three-way valve 19 and the oil drain valve 9 are not stimulated. In other words, the oil supply port 19a of the first two-position three-way valve connects with the oil delivery port 19b of the first two-position three-way valve, but the drive port 19c of the first two-position three-way valve is plugged, and The oil inlet of oil drain valve 9b disconnects with the oil outlet of oil drain valve 9a. The hydraulic oil in the first oil supply module 6 returns to the oil tank 8 via the first two-position three-way valve 19 and the oil delivery module 7. When the timing signal for valve actuation is received, the first two-position three-way valve 19 is stimulated. In other words, the oil supply port 19a of the first two-position three-way valve connects with the drive port 19c of the first two-position three-way valve, but the oil delivery port 19b of the first two-position three-way valve is plugged. After the hydraulic oil passes the first two-position three-way valve 19, it flows into the first oil supply module 6 under the drive mode, conquers the acting force of the spring of the valve actuation module 1 and actuates to open the valve.
(124) b) The valve keeps opening: when the valve actuator stops receiving the timing signal, the first two-position three-way valve 19 is not stimulated. In other words, the oil supply port 19a of the first two-position three-way valve connects with the oil delivery port 19b of the first two-position three-way valve, but the drive port 19c of the first two-position three-way valve is plugged. The hydraulic oil in the valve actuation module 1 is blocked and the valve keeps at the maximum lift position. At that time, when the first oil supply module 6 is still in the oil supply phase, the hydraulic oil in the first oil supply module 6 is pushed into the oil tank 8 by the oil delivery module 7 through the first two-position three-way valve 19.
(125) c) The valve actuator for oil drain is closed: when the timing signal for valve actuation for oil drain is not received, the oil drain valve 9 is stimulated and the oil inlet of oil drain valve 9b connects with the oil outlet of oil drain valve 9a. Under the effect of the spring of the valve actuation module 1, the hydraulic oil in the valve actuation module 1 returns to the oil tank 8 via the first oil drain path under the drive mode, so as to realize the oil drain close process of the valve. At that time, when the first oil supply module 6 still stays in the oil supply phase, the hydraulic oil in the first oil supply module 6 is pushed back to the oil tank 8 by the oil delivery module 7 via the first two-position three-way valve 19.
(126) (b) In the Oil Absorption Phase of the First Oil Supply Module 6: 120 C.A-240 C.A
(127) At that time, the first drive port 2e of the phase limit module disconnects with the first oil drain port 2c of the phase limit module. The following events can be realized:
(128) a) The valve keeps opening: when the first two-position three-way valve 19 is not stimulated, the hydraulic oil in the valve actuation module 1 is blocked and the valve keeps at the maximum lift position. At that time, the first oil supply module 6 still stays in the oil absorption phase and the hydraulic oil in the oil tank 8 flows into the first oil supply module 6 via the oil delivery module 7 and the first two-position three-way valve 19.
(129) b) The valve actuator is closed for oil absorption: when the timing signal for closing the valve for oil absorption is received, the first two-position three-way valve 19 is stimulated. In other words, the oil supply port 19a of the first two-position three-way valve connects with the drive port 19c of the first two-position three-way valve, but the oil delivery port 19b of the first two-position three-way valve is plugged. Under the oil absorption effect of the first oil supply module 6 and the spring of the valve actuation module 1, the hydraulic oil in the valve actuation module 1 returns to the first oil supply module 6 via the drive oil path, and the first two-position three-way valve 19 under the drive mode, so as to close the valve for oil absorption.
(130) (2) When the Valve Keeps Closing: 240 C.A-720 C.A
(131) In this phase, the phase limit module 2 disconnects the first oil supply port 2b of the phase limit module and the first drive port 2e of the phase limit module, disconnects the first oil drain port 2c of the phase limit module and the first drive port 2e of the phase limit module, but connects the second oil drain port 2d of the phase limit module and the first drive port 2e of the phase limit module. Under the drive, the second oil drain path is completely connected, i.e. the first drive port 22g of the mode selection module, the first drive oil supply port 22a of the mode selection module, the first drive port 2e of the phase limit module, the second oil drain port 2d of the phase limit module, the oil control inlet 22r of the mode selection module and the oil control outlet 22s of the mode selection module. The valve actuation module 1 connects with the oil tank 8 via the second oil drain path under the drive mode, the valve can be closed and keep closing and also the valve gap adjusting module can be replaced.
(132) (II) Brake Mode
(133) When the internal combustion engine stays in the brake mode as the consumption power, the movement of the drive mode selection module 22 makes the first oil supply port 22a of the mode selection module, the second oil supply port 22b of the mode selection module, the first drive port 22g of the mode selection module and the second drive port 22h of the mode selection module are connected to each other, but makes the oil control inlet 22r of the mode selection module disconnect to the oil control outlet 22s of the mode selection module. At that time, the work scope of the valve actuation module 1 is limited by the movement law of the first oil supply module 6 or the second oil supply module 5 and the phase limit module 2, and specific valve operation parameters are adjusted according to the working status of the oil drain valve 9 and the second two-position three-way valve 21 or the first two-position three-way valve 19. Its working process is stated below:
(134) (1) When the Valve can be Actuated by the First Oil Supply Module 6: 0 C.A-240 C.A
(135) This phase is an oil supply+oil absorption operation period in which the first oil supply module 6 starts from the oil supply starting point. Meanwhile, the phase limit module 2 makes the first oil supply port 2b of the phase limit module connects with the first drive port 2e of the phase limit module, makes the second oil supply port 2a of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the second oil drain port 2d of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the first oil supply port 2b of the phase limit module disconnect to the second drive port 2f of the phase limit module, makes the second oil supply port 2a of the phase limit module disconnect to the second drive port 2f of the phase limit module, makes the second oil drain port 2d of the phase limit module connect to the second drive port 2f of the phase limit module, and makes the first oil drain port 2c of the phase limit module disconnect to the second drive port 2f of the phase limit module. Under the brake mode, the first valve brake oil path is completely connected, i.e. the first oil supply port 2b of the phase limit module, the first drive port 2e of the phase limit module, the first oil supply port 22a of the mode selection module, the first drive port 22g of the mode selection module and the second drive port 22h of the mode selection module.
(136) (a) In the Oil Supply Phase of the First Oil Supply Module 6: 0 C.A-120 C.A
(137) The phase limit module 2 makes the first oil drain port 2c of the phase limit module connect to the first drive port 2e of the phase limit module. Under the brake mode, the first oil drain path is completely connected, i.e. the first drive port 22g of the mode selection module and the second drive port 22h of the mode selection module, the first oil supply port 22a of the mode selection module, the first drive port 2e of the phase limit module and the first oil drain port 2c of the phase limit module. Except different actuation oil paths, the valve operation process that can be realized in this phase is a same with the valve operation process in the oil supply phase of the first oil supply module 6 when the valve can be actuated under the drive mode, so hereby it is not repeated.
(138) (b) In the Oil Absorption Phase of the First Oil Supply Module 6: 120 C.A-240 C.A
(139) The phase limit module 2 makes the first oil drain port 2c of the phase limit module disconnect to the first drive port 2e of the phase limit module. Except different actuation oil paths, the valve operation process that can be realized in this phase is the same with the valve operation process in the oil absorption phase of the first oil supply module 6 when the valve can be actuated under the drive mode, so hereby it is not repeated.
(140) (2) When the Valve Keeps Closing: 240 C.A-360 C.A
(141) In this phase, the phase limit module 2 makes the first oil supply port 2b of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the second oil supply port 2a of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the second oil drain port 2d of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the first oil drain port 2c of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the first oil supply port 2b of the phase limit module disconnect to the second drive port 2f of the phase limit module, makes the second oil supply port 2a of the phase limit module disconnect to the second drive port 2f of the phase limit module, makes the second oil drain port 2d of the phase limit module connect to the second drive port 2f of the phase limit module, and makes the first oil drain port 2c of the phase limit module disconnect to the second drive port 2f of the phase limit module. At that time, the valve actuation module 1 is plugged and the valve can keep closing.
(142) (3) When the Valve can be Actuated by the Second Oil Supply Module 5: 360 C.A-600 C.A
(143) This phase is an oil supply+oil absorption operation period in which the second oil supply module 5 starts from the oil supply starting point. Meanwhile, the phase limit module 2 makes the first oil supply port 2b of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the second oil supply port 2a of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the second oil drain port 2d of the phase limit module connect to the first drive port 2e of the phase limit module, makes the first oil drain port 2c of the phase limit module disconnect to the first drive port 2e of the phase limit module, makes the first oil supply port 2b of the phase limit module disconnect to the second drive port 2f of the phase limit module, makes the second oil supply port 2a of the phase limit module connect to the second drive port 2f of the phase limit module, and makes the second oil drain port 2d of the phase limit module disconnect to the second drive port 2f of the phase limit module. Under the brake mode, the 2nd valve brake oil path, the second oil supply port 2a of the phase limit module, the second drive port 2f of the phase limit module, the first oil supply port of the mode selection module 2b, the first drive port 22g of the mode selection module and the second drive port 22h of the mode selection module are completely connected.
(144) (a) In the Oil Supply Phase of the Second Oil Supply Module 9: 360 C.A-480 C.A
(145) The phase limit module 2 makes the first oil drain port 2c of the phase limit module connect to the second drive port 2f of the phase limit module. Under the brake mode, the second oil drain path is completely connected, i.e. the first drive port 22g of the mode selection module and the second drive port 22h of the mode selection module, the second oil supply port 2a of the phase limit module, the second drive port 2f of the phase limit module and the first oil drain port 2c of the phase limit module. The valve operation process that can be realized in this phase is the same with the valve operation process in the oil supply phase of the first oil supply module 6 when the valve can be actuated under the drive mode. The difference is that: drive oil paths are different, the oil supply module is the second oil supply module 5, and electromagnetic valves are the second two-position three-way valve 21 and the oil drain valve 9, so hereby it is not repeated.
(146) (b) In the Oil Absorption Phase of the Second Oil Supply Module 5: 480 C.A-600 C.A
(147) The phase limit module 2 disconnects the first oil drain port 2c of the phase limit module with the second drive port 2f of the phase limit module. The valve operation process that can be realized in this phase is the same with the valve operation process in the oil absorption phase of the second oil supply module 5 when the valve can be actuated under the drive mode. The difference is that: drive oil paths are different, the oil supply module is the second oil supply module 5, and electromagnetic valves are the second two-position three-way valve 21 and the oil drain valve 9, so hereby it is not repeated.
(148) (4) When the Valve Keeps Closing: 600 C.A-720 C.A
(149) This phase is the same with the second phase of the brake mode, so hereby it is not repeated.
(150) In the same operation period of the phase limit module, one valve can be actuated under the drive mode, but two valves can be actuated under the brake mode. Therefore, the variable valve event required by the 360 C.A/cycle air compressor brake mode can be realized.
(151) On condition of different cylinder numbers, different valve variability, brake mode availability, different brake modes and different control positions, the operation process of the valve actuation system is slightly different, based on operation characteristics of various components of the system and according to the actual condition. These slight differences are introduced in the form but not illustrated separately in detail. Table 6-Table 8 show oil supply and control components of the valve actuation module of each cylinder under the drive mode, drain-for-drain &drain-for-supply brake mode and supply-for-supply & brake-for-brake mode respectively. Thereof, types of systems numbered from 1 to 6 are the continuously variable type controlled on the oil supply side, the continuously variable type controlled on the valve side, the fully variable type of the non-independent oil drain valve controlled on the valve side, the fully variable type of the independent oil drain valve controlled on the oil supply side and the fully variable type of the independent oil drain valve controlled on the valve side. The symbol + means that the control valve is placed on the oil supply port side of the mode selection module and the symbol means that the control valve on the drive port side of the mode selection module.
