ABSTRACT:
According to a prepared program and the signal from a crank angle sensor, a computer switches two operation modes A and B in which an electric motor operates, and the computer creates a pair or pairs of different operation mode phases during the period from an ignition time to the next ignition time. As a result, the sum of the second period BB of the generating phase B and the first period AA of the succeeding driving phase A is long as compared with a conventional engine. If an initial period in an intake stroke or an exhaust stroke is set within the long period sum, it is possible to reduce intake loss or exhaust loss.
