A method and apparatus for active coolant volume reduction management in a pressurized reservoir coolant diverter for automobile applications. Specifically, an apparatus and method for diverting coolant flow around a pressurized coolant reservoir until the engine has reached operating temperature by employing a coolant bypass chamber and bypass shutoff valve and the like.

A coolant control valve unit includes: a valve housing including a barrier rib where a coolant path and a fail-safe path are formed, the valve housing further including an exhaust path through which coolant exhausted through the coolant path passes; a valve disposed to open and close the coolant path; an actuator that opens or closes the coolant path by moving the valve; a flow guide extended from the barrier rib, of which an end is formed in a flow direction of the coolant in the exhaust path, and guiding a flow of coolant exhausted through the coolant path and a flow of coolant exhausted through the fail-safe path; and a fail-safe valve closing the fail-safe path by being inserted into the fail-safe path, while opening or closing the fail-safe path by a coolant temperature.

A control method for a cooling system is provided. The system includes a vehicle operation state detecting portion having an ambient temperature sensor, first and second coolant temperature sensors, a coolant control valve unit that adjusts opening rates of first, second, and third coolant passages and a controller. The method includes determining whether an output signal of the ambient temperature sensor satisfies a predetermined an ambient low temperature driving condition and whether an output signal of the first coolant temperature sensor satisfies a predetermined first low temperature driving condition when the output signal of the ambient temperature sensor satisfies the predetermined the ambient low temperature driving condition. The coolant control valve unit opens the first and coolant passages and closes the second coolant passage when the output signal of the first coolant temperature sensor satisfies the predetermined first low temperature driving condition.

A method for controlling a cooling system for a vehicle is provided. The system includes an engine, an EGR cooler, an oil cooler, a heater, a radiator, and a controller. The engine, the EGR cooler, the oil cooler, the heater, and the radiator are respectively connected through a coolant line and coolant circulates through the engine, the EGR cooler, the oil cooler, the heater, and the radiator by operation of a water pump. The controller receives the coolant from the engine and operates a control valve connected with the oil cooler, the heater, and the radiator. The method includes: sensing driving conditions and operating the control valve when a cooling mode is required to decrease the temperature within the vehicle based on the sensed driving conditions. The control valve is operated based on modes controlled depending on a coolant temperature, and among the plurality of modes, one is iteratively performed.

A system for feeding water to at least one combustion chamber in an internal combustion engine having: a tank designed to contain a quantity of water; a feeding duct; a pump designed to draw water from the tank and to pump pressurised water into the feeding duct; and at least one silver-containing body which is contained in the tank in contact with the water.

A valve that has an inlet and an outlet in fluid connection in a first position. When the valve is in a second position fluid enters the first inlet and exits the second outlet and enters in a second inlet and out the first outlet. The valve can be used for example to add a fluid circuit to a preexisting circuit.

A cooling device includes: an air blast passage; a heater core that is disposed in the air blast passage; an air blast volume adjusting member that is opened and closed to adjust an air blast volume which flows in the heater core; a flow rate adjuster that adjusts a flow rate of the coolant which is introduced into the heater core; and a controller. The controller sets the flow rate of the coolant which is adjusted by the flow rate adjuster to be less than a lower limit value of an adjustable range of the flow rate of the coolant which is adjusted by the flow rate adjuster in a vehicle compartment air-conditioning state in which the air blast volume adjusting member allows an air blast to flow to the heater core when the air blast volume adjusting member fully closes the heater core side of the air blast passage.

A cylinder block assembly may include a cylinder block, a cylinder body disposed in the cylinder block, with a plurality of cylinder bores formed in the cylinder body, a fluid jacket, which is formed between an inner circumferential surface of the cylinder block and an outer circumferential surface of the cylinder body, and through which coolant flows, and a block insert disposed in the water jacket and configured to guide a flow of coolant, wherein the cylinder block may include a second block coolant outlet, which is formed at a second side in a surface of an exhaust side of the cylinder block, and through which the coolant in the water jacket is discharged, and wherein the exhaust side may include a side at which combustion gas is exhausted out of the cylinder body.

A method and apparatus for active coolant volume reduction management in a pressurized reservoir coolant diverter for automobile applications. Specifically, an apparatus and method for diverting coolant flow around a pressurized coolant reservoir until the engine has reached operating temperature by employing a coolant bypass chamber and bypass shutoff valve and the like.

A warm-up device is provided in a cooling-water circuit, through which cooling water is circulated so as to pass through an engine. The warm-up device has a heat accumulating passage, in which a heat accumulating device is provided, and an accumulating-device bypassing passage bypassing the heat accumulating device. A waste-heat collecting device is provided in the cooling-water circuit so that heat is collected from exhaust gas from the engine and such collected heat is accumulated in the heat accumulating device. The cooling water is circulated through the heat accumulating device during a start-up operation of the engine in order to heat the cooling water flowing into the engine so as to quickly warm up the engine.
