Предложена система датчиков для распознавания цилиндров в двигателе внутреннего сгорания с датчиком коленвала с диском с базовой меткой и датчиком распределительного вала с длинными и короткими сегментами, а также короткими и длинными промежутками между сегментами. Путем комбинации выдаваемых обоими датчиками последовательностей импульсов достигается однозначная комбинация высоких и низких фаз, которая делает возможным однозначное и быстрое распознавание групп цилиндров. В ответ на это пуск последующей системы впрыска происходит таким образом, что во все цилиндры, которые еще "не заперты до впуска", производится одновременный впрыск. При неисправности датчика коленвала возможен аварийный ход с использованием сигнала распределительного вала, так как комбинация высоких и низких фаз делает возможным распознавание цилиндров и полученные при постоянном угловом интервале задние фронты сигнала распределительного вала могут служить триггерной меткой для зажигания или впрыска.A sensor system is proposed for recognizing cylinders in an internal combustion engine with a crankshaft sensor with a disc with a base mark and a camshaft sensor with long and short segments, as well as short and long intervals between the segments. By combining the pulse sequences generated by both sensors, an unambiguous combination of high and low phases is achieved, which makes it possible to unambiguously and quickly recognize cylinder groups. In response to this, the follow-up injection system starts up in such a way that a simultaneous injection is made to all cylinders that are not “locked to the intake” yet. If the crankshaft sensor malfunctions, an emergency run using the camshaft signal is possible, since the combination of high and low phases makes it possible to recognize the cylinders and the rear edges of the camshaft signal obtained at a constant angular interval can serve as a trigger mark for ignition or injection.
