Method and device for phase recognition in a 4-stroke Otto engine with ion flow measurement |
摘要 |
A device and a method for detecting phase in four-stroke engines, in which an electronic control unit (ECU) detects a spark current as a measuring signal and determines whether ignition occurred for ascertaining the compression cycles of the cylinders, whereby the electronic control unit is able to cause the injection to be performed in a correct phase relation.
