    摘要： Provided is a variable valve lift internal combustion engine including a control shaft (24) pivotally supported by a cylinder head (1) via a pivot arm (23c) pivotally supported by the cylinder head so as to able to move angularly around a rotational center line extending in parallel with an axial line of the control shaft, a power transmitting member (23a) supported by the control shaft, an actuator (21) for causing an angular movement of the control shaft around the rotational center line via the power transmitting member and a control arm (25) having a base end pivotally supported by the control shaft and a free end interposed between a cam lobe (4d) of an engine camshaft (4) and a part of a rocker arm (6). The lift of the engine valve can be varied by angularly moving the control shaft around the rotational center line and moving the base end of the control arm.

    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.
