control procedure for luftverdichtende brennkraftmaschinen

摘要

A control method as described, the method being intended for use controlling the operation of a compression ignition internal combustion engine (32) having an accelerometer (34) associated therewith and arranged to sense vibrations of the engine (32), and monitor means arranged to monitor the output signal of the accelerometer (34), the method comprising the steps of monitoring the output signal during a detection time interval and a reference time interval, using the output signal during the reference time interval to compensate for background noise, and using the noise compensated signal in controlling the operation of the engine (32).
