    摘要: An engine intake air quantity control apparatus is provided with a throttle valve, a supercharger, a variable intake valve operating device and an intake air control device. The throttle valve varies an intake air flow passage area of an intake passage. The supercharger supercharges intake air. The variable intake valve operating device changes an intake valve timing of an intake valve in accordance with an engine operating state. The intake air control device increases an opening degree of the throttle valve in accordance with a detected increase of an accelerator pedal depression amount, and increases an intake air quantity by starting to supercharge the intake air with the supercharger upon a prescribed throttle valve opening degree having been reached. The intake air control device changes the prescribed throttle valve opening degree in accordance with the intake valve timing of the intake valve.

    摘要: In this apparatus, maintaining control (time t1 to t2) which instructs fixing of the open timing VVT of an intake valve is executed in a predetermined low load state. Subsequently, there are executed changing control which instructs changing of the open timing VVT by a predetermined amount (time t2), and maintaining control which again instructs fixing of the open timing VVT of the intake valve (time t2 to t3). An intake-valve control apparatus is determined to be "anomalous" when an change amount Δave (= ave2 - ave1) between the average ave1 of a large number of sample values of ΔMFBβ (combustion percentage increase amount within a predetermined crank angle range in an expansion stroke) during the maintaining control before execution of the changing control and the average ave2 of a large number of sample values of ΔMFBβ during the maintaining control after execution of the changing control is less than a predetermined value C.

    摘要: The present invention relates to an internal combustion engine that can be operated in a homogenous charge combustion mode as well as a method and a computer readable storage device for controlling such an engine. The engine comprises at least one fuel injector through which fuel is introduced into the combustion chamber for the first cylinder, a fuel injection controller 4 that at least controls the fuel amount injected into the first cylinder and a piston in the first cylinder whose compression causes an air and fuel mixture to be ignited. The engine further comprises at least one inlet valve admitting air into the first cylinder, at least one exhaust valve for exhausting combusted gases from the first cylinder and at least one sensor for measuring an engine operation parameter in the first cylinder.
    A valve operation controller 12 is adapted to close the exhaust valve or valves before top dead centre during the exhaust stroke of the piston in the first cylinder and open the intake valve or valves between the top dead centre of the exhaust stroke and the top dead centre of the compression stroke in the first cylinder. The fuel injection controller 4 is adapted to control at least the fuel injection amount so as to perform at least one first fuel injection in the first cylinder before top dead centre of the piston exhaust stroke in the first cylinder and at least one second fuel injection in the first cylinder between the top dead centre of the exhaust stroke and the top dead centre of the compression stroke in the first cylinder. In order to solve the above mentioned problems, the engine is particularly characterized in that the valve operation controller 12 is adapted to determine the opening IVO/EVO and closing IVC/EVC of the valves of the first cylinder on the basis of the first injection or injections PFO.
