Abstract
A control system comprising a variable valve timing mechanism (B) able to set a closing timing of an intake valve (), a fuel injector () for feeding fuel to a combustion chamber (), an intake air amount detector () for detecting an amount of intake air fed to an intake passage from the outside air, and a pressure sensor () for detecting the pressure in the intake passage downstream of a throttle valve (). When air in the combustion chamber () is blown back to the intake passage when injection of fuel is restarted after the fuel injection is stopped at the time of deceleration operation, the basis for calculation of the fuel injection amount in the initial cycle when fuel injection is restarted is switched from the amount of intake air detected by the intake air amount detector () to the pressure in the intake passage detected by the pressure sensor ().
