START CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a start control device for an internal combustion engine capable of shortening start time of an internal combustion engine by push-start and accelerating according to demand of a driver. SOLUTION: An ECU 1 controls start of the internal combustion engine 50 by push-start in a vehicle provided with the internal combustion engine 50, and is provided with a specific intake air quantity control means controlling an electronic control throttle 10 based on accelerator operation quantity when the internal combustion engine 50 is started by push-start and a specific ignition timing control means controlling ignition timing of the internal combustion engine 50 based on accelerator operation quantity when the internal combustion engine 50 is started by push-start. The specific intake air quantity control means controls the electronic control throttle 10 to fully open an intake air passage when accelerator operation quantity is smaller than a predetermined valueθth. The specific ignition timing control means controls ignition timing to a retarded side at higher speed as the accelerator operation quantity is smaller when the accelerator operation quantity is smaller than the predetermined valueθth.
