    摘要： When the first fuel injection is performed after reversion from the fuel cut, the fuel pulse width Ka·INJ.PW is set so that a fuel supply amount is greatly increased in relation to an intake air amount, and the ignition timing is set to the first retarded ignition timing θa. When the second and subsequent fuel injections are performed, the fuel pulse width Kb·INJ.PW that is smaller in increase width of fuel is set, and the ignition timing is set to the second retarded ignition timing θb that has a retardation amount smaller than that of the first retarded ignition timing θa.

    摘要： In a cylinder injection engine which includes an injection valve disposed in the vicinity of an intake port of the engine and adapted to inject fuel into the combustion chamber, a spark plug disposed closer to the center portion of the combustion chamber than the injection valve, and a piston having a cavity formed in the top face that substantially faces the injection valve and the spark plug, the cavity is formed by smoothly connecting a curved surface located below the spark plug and a curved surface located below the injection valve via a connection curved surface. The curvature .kappa..sub.1 of the curved surface located under the injection valve and the curvature .kappa..sub.2 of the curved surface located under the spark plug satisfy a relationship .kappa..sub.1

    摘要： In an idling speed control method for adjusting the amount of intake air supplied to an internal combustion engine so that the engine speed matches a target speed when the engine is idling, a value of a stroke period or speed of the engine is detected. Further, a target torque improvement rate Mi, indicative of excess or deficiency of an engine output torque caused by a response delay in an intake system of the engine, is predicted in accordance with the detected value of the stroke period. Also, in accordance with the predicted torque improvement rate Mi, an ignition timing is delayed or advanced and the fuel supply quantity is increased or decreased to make an air-fuel ratio rich or lean. This eliminates the excess or deficiency of the intake air supply due to the response delay in the intake system relative to fluctuations in idling speed, thereby permitting stable idling even at low speed.
