Title:
FUEL INJECTION CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2012/035635
Kind Code:
A1
Abstract:
When performing a divided pilot injection of a first pilot injection and a second pilot injection, the second pilot injection pressure setpoint value is set depending on whether the pilot injection is required to perform a preheating function or a premixing function. After the first pilot injection, the fuel pressure, rising and falling due to pulsation generated inside the injector, is detected by means of a sensor, and the second pilot injection is performed at a timing at which said fuel pressure matches the second pilot injection pressure setpoint value.
