Abstract
In a multiple cylinder four-stroke engine with fuel injection, an interference oscillation is generated briefly on the flywheel on starting by varied fuel supply to different cylinders. After oscillation analysis of the resultant oscillation of the flywheel, phase positions of the superimposed interference oscillation and of the resultant oscillation are compared. If predetermined phase positions of the oscillations appear, the engine is considered to be operating in the correct cycle position, but otherwise a control unit is initiated to correct its cycle position so that the correct cycle position of the engine is obtained.
