Title:
METHOD FOR INJECTING FUEL DURING THE STARTING PHASE OF AN INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO2002040847
Kind Code:
A3
Abstract:
During the starting phase of an internal combustion engine with fuel injection so-called pilot injectors (I) are used to establish a film on the cylinder walls and at the same time to provide an ignitable mixture for the first combustion. At this point in time the cam shaft and the crankshaft are not yet synchronized and the position of the pistons is unknown. The method according to the invention allows determination of the sequence of the pilot injectors (I) depending on the possible relative positions during the stop periods of the internal combustion engine, said positions being known beforehand.
