Abstract (en)
[origin: WO0065217A1] The invention relates to a method and system for controlling fuel supply to a combustion engine (1) comprising at least two cylinders (4a...4d) during a start attempt. Injectors (13) for individual cylinders (4a...4d) are controlled such that the air-fuel ratio (A/F) obtained varies for each cylinder (4a...4d) by an amount DELTA f. The fuel injection to the cylinders (4a...4d) varies between the leanest air-fuel ratio and the richest airfuel ratio practically feasible during starting. If the engine (1) does not start within a predetermined number of cycles an incremental increase ( DELTA fSTEP) of the fuel supply is initiated for each predetermined number of cycles following thereafter.
