摘要： A direct fuel injection-type spark-ignition internal combustion engine is disclosed. The engine comprises a fuel injector for injecting fuel as a spray in nearly the shape of a fan having a relative small thickness, a spark plug and a cavity formed on the top surface of a piston. The cavity has a long and narrow groove-like shape. The spray is injected by the fuel injector such that the spray is almost parallel with the center axis of the piston, and impinges in the cavity. The spark plug is arranged in the upper portion of the cylinder to face the cavity.

摘要： A control device is applied to a multi-cylinder 4-cycle charge compression ignition-type internal combustion engine. The control device operates to open an exhaust valve in an exhaust stroke of each cylinder, operates to close an intake valve before an intake bottom dead center, and then, operates to open the exhaust valve again before the intake bottom dead center. An exhaust flow rate regulating valve is disposed in a collecting portion of an exhaust path and its opening is controlled. Hereby, a period in which the exhaust valve is open in an intake stroke of one cylinder and a period in which the exhaust valve is open in an exhaust stroke of another cylinder partially overlap each other. Combustion gas pushed out of a combustion chamber of the other cylinder in the overlapping period is pushed into a combustion chamber of the one cylinder via the exhaust path.

摘要： The fuel injection apparatus includes: a fuel injector having a leading end that has an internal space in which fuel is accumulated and has a fuel injection port; and an adsorbent, capable of selectively adsorbing an alcohol component in a blended fuel of gasoline and alcohol, disposed in the internal space. The fuel injection apparatus controls an injection amount from the fuel injector such that an air-fuel ratio is a controlled target air-fuel ratio based on an alcohol concentration of a blended fuel supplied to the fuel injector. In this fuel injection apparatus, a fuel pressure is brought to a predetermined high fuel pressure during cold starting of the internal combustion engine. At this time, an adsorbed amount of alcohol on the adsorbent is estimated and any deviation in the air-fuel ratio of the internal combustion engine is corrected based on the adsorbed amount of alcohol.
