摘要
In controlling a fuel injection quantity by an electromagnetic spill valve on-off operated at a target spill angle in accordance with an angle count number and a time count number of an engine rotation, based on the engine rotation angle signal outputted through a predetermined crank angle, the angle count number is set at a predetermined value during idling and time count is constantly started from one and the same point of on-off operate the electromagnetic spill valve. In consequence, the control of the fuel injection quantity does not fluctuate during idling irrespective of various factors of dispersion. On the other hand, during non-idling, the angle count number varying in association with the target spill angle is determined and the time count is started from the end point of the angle count number to control the electromagnetic spill valve. In consequence, an adverse influence suh as an engine stall is not rendered to the normal operating conditions.
