STARTUP CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINES AND STARTUP CONTROL METHOD.

摘要

A startup control device for internal combustion engines, comprising: a strong cranking device capable of cranking an internal combustion engine up to a target idle speed; and a weak cranking device not capable of cranking the internal combustion engine up to the target idle speed. This startup control device for internal combustion engines includes: a startup mode determination unit that determines whether to start up in a combustion-pressure-free mode in which the internal combustion engine is started using the strong cranking device, or in a combustion pressure mode in which the internal combustion engine is started up by using a combination of combustion pressure generated by supplying fuel to the internal combustion engine and cranking using the weak cranking device; and an air intake volume control unit that causes the amount of intake air during cranking to differ when starting in the combustion-pressure-free mode and when starting in the combustion pressure mode.
