Operating method for a fuel-injected combustion engine, in which the stroke and duration of opening of the fuel injector closing body are adjusted according to whether the engine is operating in homogeneous or layered charging mode

摘要

A method for forming an ignitable fuel-air mixture in the combustion space of a fuel-injected petrol engine (2) that has a fuel-injection jet with a closing body. The engine can be operated in homogeneous or layered charging mode. In the latter the stroke of the closing body is adjusted, while in the former the stroke length is reduced relative to the latter and the duration of fuel injection increased.
