Abstract
An engine comprises an intake control valve disposed in an intake passage at an upstream side of an intake valve in each cylinder for individually opening/closing the intake passage, an actuator for opening/closing the intake control valve, and a control device for controlling an operation of the actuator, wherein the control device controls the actuator to delay opening of the intake control valve in relation to opening of the intake valve, thus performing the supercharge. Supercharge correction is further performed for correcting operating timing of the actuator so that unbalance in a supercharge air quantity between the cylinders in the engine is suppressed.
Claims14
A control device for an engine comprising:
- an intake control valve disposed in an intake passage at an upstream side of an intake valve in each cylinder for individually opening/closing the intake passage;
- an actuator for opening/closing the intake control valve;
- and
- control means for controlling an operation of the actuator, wherein the control means controls the actuator to delay opening of the intake control valve in relation to opening of the intake valve, thus performing supercharge of the engine, further comprising:
- supercharge correction means for individually correcting operating timing of the actuator based on state value detected for each of the cylinders so that unbalance in a supercharge air quantity between the cylinders in the engine is suppressed.
