摘要： A variable valve timing apparatus for an internal combustion engine, includes an actuator (15) that operates a first variable valve timing mechanism; a detecting portion (35) that detects a driving position of the actuator (15); and a control portion (21) that executes an initialization process only when a preset execution condition is satisfied. In the initialization process, the control portion drives the actuator (15) to one end of a driving range and sets the driving position detected in this state as an initial value, and then drives the actuator (15) to an opposite end of the driving range and reflects an offset amount of the driving position detected in that state with respect to an optimum value in the driving position to compensate for the offset amount. The execution condition includes a condition that an increase amount in acceleration required of the internal combustion engine (1) be equal to or greater than a preset first determining value.

摘要： A control apparatus of a variable valve system includes a variable valve timing mechanism that performs variable control of the valve timing of an intake valve of an internal combustion engine, a variable operation angle mechanism that performs variable control of the operation angle of the intake valve, and a control unit that performs drive control of the variable valve timing mechanism and the variable operation angle mechanism. The control unit sets an upper guard for the operation angle according to an actual value of the valve timing, and when a target value of the valve timing is a value on the retard side of a specified determining value, the control unit reinforces the upper guard compared with when the target value of the valve timing is not a value on the retard side of the specified determining value.

摘要： A detecting apparatus that detects an abnormality of imbalance of air-fuel ratios among cylinders of a multi-cylinder internal combustion engine, which is equipped with a variable working angle mechanism of an intake valve, the detecting apparatus includes an abnormality detection portion that detects a parameter regarding rotational fluctuations of each of the cylinders and detects whether or not there is an abnormality of imbalance of air-fuel ratios among the cylinders. The abnormality detection portion refrains from determining that the air-fuel ratios are normal when the working angle at the time of detection of the parameter is within a predetermined large working angle range, and determines that the air-fuel ratios are normal when the working angle at the time of detection of the parameter is within a predetermined small working angle range that is on a small working angle side with respect to the large working angle range.
