ABSTRACT:
An engine has a crankshaft and cylinders. Each of the cylinders is associated with an ignition coil and a power transistor for controlling the ignition coil. Reference signals are generated at reference crank angles corresponding to the cylinders respectively. The cylinders are separated into groups and the cylinders in a common group are different from each other by an interval of 360.degree. in crank angle. The reference signals corresponding to the cylinders in a common group are similar to each other. The reference signal corresponding to the cylinder in a group is different from the reference signal corresponding to the cylinder in other group. The reference signal corresponding to preset one of the cylinders is different from the reference signals corresponding to the other cylinders. During engine start, sparks are caused simultaneously in the cylinders in a common group in accordance with the reference signals corresponding to said cylinders in said group until the reference signal corresponding to the preset cylinder is generated. When and after the reference signal corresponding to the preset cylinder is generated, a spark is caused in one of the cylinders sequentially in a predetermined order starting from the preset cylinder.
