Disclosed is a reluctor plate controller that detects vacuum and pressures in the engine which are used to create digital motor control signals for controlling a reluctor plate actuator using a digital stepper motor, servo motor or a voice-coil actuator. The system can be programmed to create various desired responses that function to create better efficiency of an internal combustion engine, less pollution and/or greater engine output.

The present disclosure relates to a carburetor assembly (7) comprising a control unit (17), an air channel (8), a throttle valve (9), a choke valve (10), a pulsed fuel valve (11), and a fuel supply line (12). The control unit (17) is adapted to control the fuel valve (11) to supply fuel in accordance with a certain start setting, where the choke valve (10) can be open or closed. The carburetor assembly (7) comprises a rotation angle detector assembly (20) with a choke detector part (29) that is mounted to a choke shaft (30) that is connected to the choke valve (10) such that the choke detector part (29) is arranged to rotate together with the choke valve (10).

A temperature control throttle device is provided. The temperature control throttle device includes: at least one throttle; a first pipeline and a second pipeline, wherein, the first pipeline and the second pipeline are connected to the same side of the at least one throttle in an air flow direction in parallel, and wherein the second pipeline is provided with a heat exchanger that heats air flowing through the second pipeline with engine coolant, engine oil or engine exhaust gas as a heat source.

The present invention relates to internal combustion engines. More particularly, the present invention relates to an arrangement whereby internal combustion engines can be operated more efficiently at higher compression pressures. Aspects and/or embodiments seek to provide a method and/or apparatus and/or system for using very high compression ratios in internal combustion engines while preventing damage from pinking or knocking.

A throttle-controlled intake system is disclosed that provides a driver of a vehicle with greater control over engine functions and vehicle performance. The throttle-controlled intake system includes a control module that is coupled with an aircharger air intake. The control module processes input signals from a throttle pedal of the vehicle and sends modified throttle position signals to a throttle body of the vehicle so as to increase throttle responsiveness of the vehicle. The throttle-controlled intake system further includes a wiring harness and a signal adjuster. The wiring harness electrically couples the control module with the throttle pedal and the throttle body. The control module sends signals directly to the throttle body of the engine, bypassing an electronic control unit of the vehicle. The signal adjuster includes a rheostat that enables manual adjustment of the throttle responsiveness of the vehicle.

In at least some implementations, a method of controlling fuel injection events, includes determining at least one engine operating condition, determining timing of a desired pressure in an engine intake chamber or at the outlet of a fuel injector, and initiating a fuel injection event as a function of the at least one engine operating condition and the desired pressure. The fuel injection event is initiated prior to the desired pressure occurring and wherein the fuel injection event occurs for a duration such that the fuel injection event terminates after the desired pressure occurs.

In the present invention, a clogging rate is calculated using a first flow rate function when the degree of clogging of the throttle valve is in the reference state and a second flow rate function estimated based on the intake air volume. For each predetermined period, sample points, which are combinations of the second flow rate function and throttle valve position, are obtained, and the learning points are calculated by averaging a plurality of sample points for each predetermined position range. Based on the plurality of learning points, coefficients a to c of the approximate function of the second flow rate function characteristic are calculated by the least-squares method, and the clogging rate is calculated based on the second flow rate function characteristic and the first flow rate function approximated by the approximate function using the coefficients a to c.

Proposed is a method and system for controlling an Exhaust Gas Recirculation (EGR) device in high-load driving, and an internal combustion engine vehicle including the system. The method of controlling an EGR device in high-load driving compares a ratio of pressures at a front end and a rear end of a throttle valve with a preset critical value that is a reference for determining high-load driving, performs Wide Open Throttle (WOT) control for fully opening the throttle valve when the ratio of pressures is larger than the preset critical value, determines whether engine torque due to the WOT control and use of EGR satisfies torque requested by a driver, and corrects throttle opening or stops use of EGR, depending on whether the engine torque due to use of EGR together with the WOT control satisfies the requested torque.

Provided is a method of generating vehicle control data. The method is applied to a vehicle configured to select one of a plurality of traveling control modes and is executed by a processor in a state in which relationship definition data defining a relationship between a state of the vehicle and an action variable as a variable relating to an operation of electronic equipment in the vehicle is stored in a memory. The method includes operation processing for operating the electronic equipment, acquisition processing for acquiring a detection value of a sensor configured to detect the state of the vehicle, reward calculation processing for providing reward, and update processing for updating the relationship definition data.

In at least some implementations, a charge forming device includes a body that has a throttle bore, a throttle valve associated with the throttle bore, a coupler and an actuator. The throttle has a valve head received within and movable relative to the throttle bore, and a valve shaft to which the valve head is coupled. The coupler is connected to the valve shaft and carries or includes a sensor element. And the actuator has a drive shaft coupled to the coupler so that rotation of the drive shaft is transmitted to the coupler and the valve shaft.
