METHOD FOR OPERATING AN INJECTION VALVE OF AN INTERNAL COMBUSTION ENGINE |
摘要 |
The invention relates to a method for operating an injection valve of an internal combustion engine, whereby fuel dosage is adjusted especially by a variation of the stroke of the injector pin of the injection valve. Generic methods and injections valves are generally known from the prior art. The aim of the invention is to provide a method which makes it possible to avoid an incomplete closure of the valve due to soiling (danger of a damage caused by a gasoline-filled crankcase) at operating states of the internal combustion engine where no complete stroke of the injector pin occurs over a prolonged period of time and the nozzle is therefore not sufficiently scavenged. According to the invention, the nozzle is scavenged with fuel when an open jamming operating state of the injector pin is detected. |
