METHOD FOR CONTROLLING STARTING OF INTERNAL COMBUSTION ENGINE AND STARTING CONTROL DEVICE

摘要

An internal combustion engine (1) is equipped with a throttle (23) for adjusting the amount of intake air, and is started by cranking. A starter switch (36) detects the start of cranking, and crank angle sensors (33, 34) detect the rotational speed of the engine. A controller (31) initiates cranking and drives the throttle (23) to a closed position. The controller (31) counts the number of strokes or the rotational speed of the internal combustion engine (1) from the start of cranking, and when the count reaches a predetermined number, the controller (31) opens the throttle from the closed position so as to ensure a manifold vacuum for facilitating the vaporization of fuel, and to ensure the amount of intake air required to maintain the idle speed.
