ABSTRACT:
An engine control unit is configured to detect the revolution of an engine and to obtain the intensity of both the first order component of revolution for every combustion (one cycle per combustion) and the second order component of revolution. The second order is twice as much as the first order component. The unit further obtains dispersion or deviation in these intensities. Thereby, it is possible to detect combustion conditions and to correct them to desirable conditions.
