ABSTRACT:
An HCCI engine provides a negative overlap period in an operation during HCCI combustion. During the negative overlap period, an intake valve and an exhaust valve are both closed when a piston is in the vicinity of the top dead center in an exhaust stroke, so that burned gas remains inside a combustion chamber. The engine is provided with a throttle, a fuel valve and an ECU. The ECU controls the throttle during a switching period in which SI combustion is switched to the HCCI combustion so that the opening degree of the throttle increases to the opening degree at the time of steady HCCI operation from the opening degree at the time of steady SI operation, and at the same time, controls the fuel valve such that the amount of fuel supplied to the intake passage becomes greater than the amount at the time of the steady SI operation.
