FUEL INJECTION CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE |
摘要 |
A fuel injection control system for an internal combustion engine is provided which is designed to perform pilot injection of fuel into the engine through a fuel injector prior to main injection. The system monitors a combustion state parameter representing a combustion state of the fuel within a combustion chamber of the engine which has been sprayed in the event of the pilot injection. When the combustion state parameter is determined as lying out of a stable combustion range where the fuel is to burn stably, the system changes the number of pilot injections to be executed prior to the main injection and/or the quantity of the fuel to be sprayed in each pilot injection, thereby enhancing the ignitability of the fuel in the pilot injection.
