摘要： The air-fuel ratio of an air-fuel mixture supplied to an internal combustion engine is determined on the basis of a smoothed amount of intake air and a smoothed throttle opening. The smoothed amount of intake air is reflected by a predetermined ratio of a former amount of intake air to the newest amount of intake air. The smoothed throttle opening is reflected by a ratio of a former throttle opening to the newest throttle opening substantially identical to said predetermined ratio.

摘要： A method of controlling an intake air passage of an internal combustion engine is provided. The intake air passage cyclically communicates to a combustion chamber of the internal combustion engine, thereby inducting fresh air into said combustion chamber. The cyclic communication of the intake air passage to the combustion chamber generates a pressure wave in the intake air passage. The method comprises reducing an effective length of a transmission path of the pressure wave in an upstream direction of the intake air passage as a desired air flow to the combustion chamber decreases. In accordance with the method, the effective length of the pressure wave transmission path is reduced as desired air flow decreases. With the reduced effective length, the pressure wave bounces back and forth between ends of the transmission path more often before the next cyclic communication. The more bouncing attenuates the pressure wave at the next cyclic communication. Therefore, the cylinder air charge can be stabilized when the desired air flow is decreased.

摘要： An intake system for a multiple-cylinder engine has a plurality of discrete intake passages which are substantially equal to each other in length and are connected to the respective cylinders at their downstream ends. The upstream ends of the discrete intake passages are merged into an integrated chamber, and an upstream side intake passage communicates the integrated chamber with the atmosphere. The integrated chamber has an upstream side end face and a downstream side end face, and the cross-sectional area of the integrated chamber increases from the upstream side end face to the downstream side end face, the upstream side intake passage having opening into the integrated portion in the upstream side end face, and the discrete intake passages respectively having openings into the integrated chamber in the downstream side end face. The area of the upstream side and downstream side end faces of the integrated chamber S.sub.0 S.sub.1, the sum of the areas of the openings of the discrete intake passages into the integrated chamber S.sub.N and the distance H between the upstream side and downstream side end faces of the integrated chamber satisfy the following formulae ##EQU1##

摘要： A control apparatus for a direct-injection, spark-ignition engine including a temperature-condition detector for detecting a temperature condition of the engine catalyst, and a controller for controlling a fuel-injection operation. The controller controls the fuel injector to perform divided fuel injections of at least a leading fuel injection and a trailing fuel injection during a compression stroke prior to the ignition timing based upon a detection of the temperature condition in an inactivated state of the catalyst, the trailing fuel injection being performed at such a timing that its mixture concentrates adjacent to the spark plug at the ignition timing by way of high cylinder pressure during a late-stage of the compression stroke, the leading fuel injection being performed at such a timing that its mixture distributes around a mixture layer by the trailing fuel injection at the ignition timing, and a midpoint between an initiation of the leading fuel injection and an initiation of the trailing fuel injection being positioned within a period during a latter half of a compression stroke.

摘要： A fuel spray and a tumble collide with each other from approximately opposite directions in a cavity formed in a piston head so that a combustible mixture stays around a spark plug for an extended period of time. An upper opening of the cavity is elongated to both the left and right sides of a cylinder axis. The distance between a ceiling of the combustion chamber and a bottom surface of the cavity is smaller on the right side of the cylinder axis than on the left side thereof and largest at least at a point where the cylinder axis crosses the bottom surface of the cavity, and a portion of the cavity to the left of the cylinder axis has a larger volumetric capacity than a portion of the cavity to the right of the cylinder axis, whereby a strong tumble is maintained up to a fuel injection point.

A cavity is formed on the top surface of the piston. The cavity has a configuration of an elongated circle with a substantially flat bottom surface. The surrounding side wall of the cavity is substantially upright in relation to the bottom surface. A cavity centerline drawn through the longitudinal axis of the cavity is perpendicular to the injection axis line and offset from the center of the piston toward the injector.
