Abstract (en)

[origin: DE19918664A1] The invention relates to a method for synchronised ignition in an internal combustion engine with a crankshaft sensor and a device for detecting smooth running. The aim of the invention is to provide a method for synchronised ignition which does not require a camshaft sensor. After the engine has started, ignition takes place in all of the upper dead centres (OT's) in at least one cylinder, the time of ignition being offset by a certain value each time that the crankshaft passes through 720 DEG . The effect of offsetting the time of ignition is determined by the device for detecting the smoothness of running. Ignition is assumed to have occurred in the area of the upper dead centre in which the ignition time is offset when the smoothness of running is modified above a predetermined limit value or is assumed to have occurred in the area of the upper dead centre in which the ignition time is not offset when the smoothness of running is not modified above a predetermined limit value.
