CONTROL APPARATUS FOR ENGINE

A control system for an engine includes: a valve that adjusts an intake air filling amount for a cylinder according to an operation amount of an accelerator pedal; a sensor that outputs a measurement signal related to a temperature of an upper end of a cylinder head having an intake port and an exhaust port communicating with the cylinder; and a control circuit that sets an upper limit value of the intake air filling amount to be smaller as the temperature of the upper end of the cylinder head is reduced base on the measurement signal at the start of an engine, and outputs, to the valve, a control signal corresponding to the operation amount of the accelerator pedal within a range where the intake air filling amount does not exceed the upper limit value.
