Fuel supply system controlling method for e.g. petrol engine, involves presetting injecting parameters during switching process from simple fuel injection to repeated fuel injection such that specific effective efficiency is achieved

摘要

The method involves controlling injecting parameters e.g. distribution factor and injecting point, of a fuel supply system (10) in an operating mode of an internal-combustion engine in which repeated fuel injections into a combustion chamber (26) are performed. The injecting parameters are preset during a switching process from a simple fuel injection to the repeated fuel injection or vice-versa such that an effective efficiency of approximately 1 is achieved in the operating modes with simple and repeated fuel injections. An independent claim is also included for a computer program for execution of a method for controlling a fuel supply system of an internal-combustion engine.
