Abstract
Fuel amounts injected by a fuel injection valve are summed from when an engine is started to when startup is complete. The temperature of a fuel-deposited part during engine startup is estimated, and an intake rate of a fuel injection amount to a combustion chamber is found from this temperature. A fuel deposition amount at completion of startup is estimated from the sum of fuel injection amounts and this intake rate. By increasing or decreasing the fuel injection amount after startup based on this fuel deposition amount, a post startup air-fuel ratio is rapidly stabilized unaffected by scatter of startup time.
