Title: Control device for internal combustion engine
Inventor: KONDO WAKICHI
IPC: F02D41/04
Filed: 2001-12-18
Abstract: <P>PROBLEM TO BE SOLVED: To reduce vibration caused by resonance generated in an automatic- stop control of an engine.  <P>SOLUTION: In stopping the engine, a gradual control on torque is executed at the outset in order not to make a driver feel a sense of unease, and the amount of intake-air is gradually reduced by gradually reducing the lift amount of an intake valve. Accordingly, a fuel injection quantity is reduced gradually, and while the air-fuel ratio is maintained at a target air-fuel ratio, torque of the engine power is gradually reduced to decrease gradually the engine speed. At the time when the engine speed is reduced to a resonance-revolution-speed region, a control for torque rapid-reduction is executed to control the intake- valve lift-amount to a minimum value. At the same time, the throttle valve is full closed to rapidly reduce the intake air volume, and the engine power torque is rapidly decreased by stopping the fuel injection. Thus, by rapidly decreasing the engine speed in the region of the resonance revolution-velocity, the region of revolution-velocity is passed in a short period of time to reduce vibrations to be caused by resonance.  <P>COPYRIGHT: (C)2003,JPO
