ABSTRACT:
In order to control all revolution numbers of an engine at high precision, combustion of each cylinder is reliably controlled. For the combustion control of each cylinder, there are controlled measurement timings of an air volume as well as a fuel volume contributive to the combustion and exhaust gas being a combustion result, calculation timings of a fuel injection volume and an ignition timing, and output timings of fuel injection and/or ignition. These timings are synchronized by crank angle positions form a reference point such as top dead center. Particularly as to the measurement timing, a delay time of a gas stream between a measurement spot and the cylinder is compensated in terms of a crank angle corresponding thereto, whereby the variables to be measured are synchronized.
