    摘要: A process of controlling operation in a multi-cylinder engine during start of operation and low-load conditions includes skipping a supply of fuel in a first set of cylinders for a pre-defined number of multiple working cycles; supplying fuel-air mixture to a second set of cylinders in the multi-cylinder engine for the pre-defined number of multiple working cycles; executing combustion of the fuel-air mixture supplied to the second set of cylinders for the pre-defined number of multiple working cycles; and switching the supply of fuel, after the pre-defined number of multiple working cycles, from the second set of cylinders to the first set of cylinders.

    摘要: During start-up of an engine, a reverse rotation start-up operation of rotating a crankshaft in a forward direction is performed after rotation of the crankshaft in a reverse direction. In the operation, a fuel injection device injects fuel such that a fuel-air mixture is introduced into a combustion chamber from an intake passage through an intake port, at at least one of a time when the crankshaft is rotated in the reverse direction and a crank angle is in a start-up intake range and a time when the crankshaft is rotated in the forward direction and the crank angle is in the normal intake range, and an ignition device ignites the fuel-air mixture in the combustion chamber when the crank angle is in a start-up ignition range. An engine unit is controlled such that the operation is performed again, in a case in which a rotation state detected by a rotation state detector does not satisfy a predetermined start-up condition, when the crankshaft is rotated in the forward direction in the operation and before a piston reaches a first compression top dead center.

    摘要: A forward rotation positioning operation of rotating a crankshaft in a forward direction is performed before start-up of an engine, and a reverse rotation start-up operation of rotating the crankshaft in a reverse direction is performed during the start-up of the engine. In the forward rotation positioning operation, a rotation driver drives the crankshaft such that a crank angle reaches a predetermined reverse starting range. In the reverse rotation start-up operation, the rotation driver drives the crankshaft such that the crank angle exceeds a predetermined start-up intake range from the reverse rotation starting range and reaches a predetermined start-up ignition range, a fuel injection device injects fuel such that a fuel-air mixture is introduced into a combustion chamber from an intake passage through an intake port, when the crank angle is in the start-up intake range, and an ignition device ignites when the crank angle is in the start-up ignition range. Ignition performed by the ignition device is prevented during the forward rotation positioning operation.

    摘要: An object of the present invention is to control the discharge amount of unburned fuel components in the internal combustion engine. According the present invention, the number of times of execution of sub fuel injection is changed based on the operation range within which the operation state of the internal combustion engine falls so that the lower the engine load of the internal combustion engine is, and the lower the number of engine revolutions of the internal combustion engine is, the more the number of times of execution of sub fuel injection is increased. Furthermore, the lower the atmospheric pressure is, the lower the temperature of the cooling water of the internal combustion engine is, or the lower the temperature of the intake air of the internal combustion engine is, the more an operation range in which the number of times of execution of sub fuel injection is large is expanded to higher loads and higher revolutions.

    摘要: Procédé de commande d'un moteur à combustion interne de véhicule automobile muni de circuits de recirculation partielle des gaz d'échappement à haute pression et à basse pression, au cours duquel on détermine la fraction d'air frais dans le collecteur d'admission et on détermine une estimation de la fraction d'air frais en amont du papillon d'admission
    Le procédé comprend les étapes suivantes :
    on détermine une consigne de fraction d'air frais,
    on détermine la fraction de gaz frais dans le collecteur d'échappement par mesure d'une sonde de richesse à l'échappement,
    on détermine si la consigne de fraction d'air frais et si l'estimation de la fraction d'air frais en amont du papillon d'admission sont supérieures à la fraction de gaz frais dans le collecteur d'échappement,
    si tel n'est pas le cas, on commande la fermeture du circuit de recirculation partielle des gaz d'échappement à haute pression,
    si tel est le cas, on détermine une erreur de contrôle en soustrayant la consigne de fraction d'air frais de la fraction estimée d'air frais dans le collecteur d'admission,
    on estime le débit du circuit de recirculation partielle des gaz d'échappement à haute pression fonction de l'erreur de contrôle, d'un gain, d'une mesure de débit d'air, de la consigne de fraction d'air frais, de la fraction estimée d'air frais, de la fraction de gaz frais dans le collecteur d'échappement et de l'estimation de la fraction d'air frais en amont du papillon d'admission.
