摘要： An EGR control system that is capable of controlling the amount of recirculation of high-temperature and low-temperature recirculated gases, with high accuracy, to thereby improve the control accuracy of in-cylinder temperature. An ECU of an ERG control system calculates a fresh intake air ratio, and sets a target value of the fresh intake air ratio. The ECU calculates a feedback correction coefficient for converging the fresh intake air ratio to the target value, with an I-PD control algorithm, and sets an external EGR ratio and an internal EGR ratio. The ECU controls the EGR amount whose ratio is the larger, according to the larger one of the two ratios and the feedback correction coefficient, and controls the EGR amount whose ratio is the smaller, according to the smaller of the ratios and the learned value thereof.

摘要： In a variable valve opening property internal combustion engine, a control shaft (20) is supported by a control link (21) which is in turn is pivotally supported by a cylinder head (1), and a roller link (22) is pivotally supported by the control shaft. The roller link is provided with a cam roller (31) that engages a cam (3) of a camshaft (4) and a roller shaft (32) that engages a slipper surface (33) of a rocker arm (6). The arcuate movement of the cam roller centered around the control shaft varies the swing of the rocker arm and hence the valve lift in dependence on the position of the control shaft. A compression coil spring (41) is interposed between a part of the cylinder head and a side of the cam roller facing away from the cam. The coil spring is oriented such that a direction of a spring force (Fspg) substantially coincides with a direction of a guided movement of the cam roller, preferably in a low valve lift condition.

摘要： A valve actuating apparatus for an internal combustion engine selectively operating in the normal Otto cycle or the Miller cycle is provided which enables the engine to achieve stable combustion and improved fuel economy during cruising or in a low-load engine operating region. A delayed-closing cam for Miller cycle operation and a normal cam having a cam profile for earlier valve-closing timing of the intake valve than a cam profile of the delayed-closing cam are provided on a camshaft. A cam profile-switching mechanism switches between the delayed-closing cam and the normal cam, for opening and closing the intake valve. An ECU controls the switching mechanism such that when a detected operating condition of the engine indicates starting or idling, the intake valve is operated by the normal cam, and when the detected operating condition indicates cruising, the intake valve is operated by the delayed-closing cam.
