    • Tn a direct-injection internal combustion engine (1-1), a variable intake valve (41), of which valve timing can be varied, is used as an air intake valve through which an air intake path (5) and a combustion chamber (A) communicate with each other. The direct-injection internal combustion engine (1-1) includes: a variable-intake-valve control section (75) that controls the valve timing of the valuable intake valve (41); and an intake-air temperature acquisition section (74) that acquires a temperature of the intake air introduced into the combustion chamber (A). When the fuel is injected into the combustion chamber (A) via a fuel injection valve (21) during the compression stroke or the expansion stroke, if the acquired intake-air temperature is low, the closing timing of the variable intake valve (41) is advanced, so that the actual compression ratio is increased.

    • A variable compression ratio engine includes a support shaft positioned eccentrically relative to rotating shafts. A restricting projection is provided at one location in the circumferential direction on the rotating shafts so as to project outward in the radial direction. A rocker member has a pair of engagement portions with respective phases displaced from each other and which engage the restricting projection. The rocker member is spring-biased in a direction in which one of the two engagement portions engages the restricting projection and is mounted on a shaft member so as to be able to rock around the axis of the shaft member. An actuator is driven by the engine negative pressure and is connected to the rocker member so as to swing the rocker member in a direction opposite to the spring-bias direction.
