Abstract:
1. A control apparatus for an internal combustion engine, for controlling an operating condition of an internal combustion engine comprising a variable valve operating mechanism capable of changing valve operating characteristics of an intake valve and an exhaust valve, said control apparatus comprising: an intake valve controlling device for controlling the variable valve operating mechanism to set the intake valve continuously open while a lift amount is maintained to a predetermined lift amount, during a cranking operation of the internal combustion engine; an exhaust controlling device for controlling at least one of the variable valve operating mechanism and an exhaust throttle valve, to set at least one of the exhaust valve and the exhaust throttle valve continuously close, during the cranking operation, the exhaust throttle valve being disposed in an exhaust path on a downstream side of the exhaust valve; a temperature specifying device for specifying an actual temperature of cooling water for cooling the internal combustion engine; and a target temperature setting device for setting a target temperature of the cooling water to be reached during the cranking operation, said intake valve controlling device setting the predetermined lift amount, on the basis of a deviation between the actual temperature and the target temperature.
