Latest Patents
Kazushige Toshimitsu's latest invention is a novel fuel supply control method for multicylinder internal combustion engines. This method utilizes a fuel supply control system composed of a main fuel injection valve placed in the intake passage upstream of the throttle valve and an auxiliary fuel injection valve positioned downstream of the throttle valve.
In this system, fuel is supplied by the main fuel injection valve when the engine temperature is below a predetermined value. Conversely, when the temperature exceeds that threshold and the throttle valve's opening is relatively narrow, the auxiliary fuel injection valve takes over the fuel supply. The fuel pressure for both valves is meticulously regulated based on a parameter that accounts for the operating conditions of the engine, specifically the pressure within the intake passage downstream of the throttle valve. Additionally, this parameter plays a crucial role in controlling the basic fuel injection periods for both valves.
