GEBERANORDNUNG ZUR ZYLINDERERKENNUNG BEI EINER BRENNKRAFTMASCHINE MIT N ZYLINDERN

摘要

The description relates to a transmitter arrangement for cylinder recognition in an internal combustion engine with a crankshaft transmitter having an increment disc with a reference mark and a camshaft transmitter having long and short segments and short and long gaps between the segments. By combination of the pulse sequences provided by both transmitters it is possible to generate a clear combination of high and low phases which permit clear and rapid cylinder and cylinder group recognition. The start of a sequential injection system takes place in such a way that all the cylinders which may still be operated "before the inlet closes" are simultaneously injected. In the event of crankshaft transmitter failure, emergency operation is possible using the camshaft signal, since the combination of high-low phases permits cylinder recognition and the trailing edges of the camshaft signal generated at fixed-angle spacing can be used as trigger marks for ignition or injection.
