    摘要: The invention is intended to provide good emission-cleaning performance by use of a three-way catalyst alone, without the need for a lean NOx catalyst, while ensuring a fuel economy improvement effect of lean burn operation, and to improve fuel economy up to high-load operating ranges while maintaining desired engine output performance by use of a supercharger. In a pair of preceding and following cylinders whose exhaust and intake strokes overlap each other, intake air supplied to the preceding cylinder (2A, 2D) is supercharged by a turbocharger (23) to produce combustion at a “lean” air-fuel ratio in the preceding cylinder (2A, 2D), and burned gas discharged from the preceding cylinder (2A, 2D) is introduced into the following cylinder (2B, 2C) through an intercylinder gas channel (22). Combustion in the following cylinder (2B, 2C) is made at an air-fuel ratio equal to or smaller than the stoichiometric air-fuel ratio by supplying fuel to the burned gas of a “lean” air-fuel ratio introduced from the preceding cylinder (2A, 2D), and gas discharged from the following cylinder (2B, 2C) is led to an exhaust passage (20) provided with a three-way catalyst (30).

    摘要: An engine control system for diminishing driveline vibrations extracts resonant frequency component coincident in frequency with a driveline resonant vibration according to a gear ratio of a transmission of the driveline from a change in charging efficiency with time that is detected on the basis of a signal representative of an amount of intake air, converts the resonant frequency component to a demanded amount of engine torque reduction after having adjusted the resonant frequency component in phase, and causes the demanded amount of engine torque reduction by retarding an ignition timing and/or reducing an amount of fuel injection.

    摘要: An engine control system for suppressing vibration of a car body, primarily at acceleration thereof, by varying engine output torque. The system for suppression of the car body vibration takes into consideration car vibration detection delay time created by the intermittent detection of vibration data. The system includes a detector for intermittently detecting data relating to car body vibration, a period setting device for setting a period of car body vibration, a delay time setting device for setting a delay time corresponding to a detection delay time due to the intermittent detection of the vibration data detector, and a torque controller for controlling engine output torque by advancing a phase of engine output torque control timing by the delay time corresponding to the detection delay time, which is set by the delay time setting device, in each period of car body vibration set by the period setting device.
