Title: Fuel injection quantity control device for internal combustion engine
Inventor: MIZUNO HIDEAKI
IPC: F02D41/04
Filed: 1994-12-26
Abstract: PURPOSE: To prevent an air-fuel ratio from becoming lean in a combustion chamber at the transient time of shifting a mode from intake asynchronous injection to intake synchronous injection so as to prevent the degradation of drivability. CONSTITUTION: An electronic control unit(ECU) 41 controls each injector 5 in the mode of intake asynchronous injection on the basis of the computed fuel injection quantity at the low load time of an engine. The ECU 41 also controls each injector 5 in the mode of intake synchronous injection on the basis of the computed fuel injection quantity at the high load time of the engine 1. The ECU 41 controls each injector 5 so as to increase the computed fuel injection quantity by the required part at the transient time of the engine 1 shifting to the high load state.  Accordingly, at the transient time of shifting the mode from intake asynchronous injection to intake synchronous injection, even if the temperature rise of a combustion chamber 1c is insufficient, the atomized quantity of fuel in the combustion chamber 1c is increased by the increase of fuel quantity so as to prevent an air-fuel ratio from becoming lean.
