摘要： An electric current supply control apparatus for a glow plug, and glow plug and the electric current supply control apparatus connected to the glow plug. In a transition state in which the load acting on an engine increases such as at the time of acceleration (S 14: YES), an instruction signal which instructs increasing of an EGR amount is transmitted to an ECU (S18). Further, electric current is supplied to a heat generation resistor of a glow plug through resistance PI control (S20), whereby the temperature of the heat generation resistor is stably maintained at a target temperature, and stability of combustion is enhanced. Thus, even at the time of acceleration, generation of NO x can be suppressed effectively by increasing the EGR amount without lowering the engine output.

摘要： L'invention propose un procédé de contrôle d'un dispositif de motorisation de véhicule automobile comprenant un moteur diesel suralimenté ; un circuit de recirculation partielle à haute pression des gaz d'échappement à l'admission piloté par une vanne EGR ; et, des moyens de distribution à calage variable du moteur.
En dessous d'un seuil de température, on interdit l'ouverture de la vanne EGR et on compense au moins partiellement l'augmentation des émissions d'oxydes d'azote due à l'absence de recyclage de gaz d'échappement à l'admission par un croisement relativement important des soupapes du moteur. Au-dessus du seuil de température, pour le même point de fonctionnement du moteur, on autorise l'ouverture de la vanne EGR et on diminue le croisement des soupapes.

摘要： In the case of performing a main injection, and a sub-injection that injects a minute amount of fuel in a region (i) in Fig. 3, a check is conducted to determine whether or not the minute amount of fuel is injected accurately. In a specific cycle at a time of cold starting when catalyst warm-up control is performed, the main injection is omitted and a checking injection corresponding to a sub-injection is performed. Injection conditions of the in-cylinder injection valve 28 are made uniform between the checking injection and the sub-injection. A fuel amount that is actually injected from the in-cylinder injection valve 28 in the specific cycle is calculated based on the air-fuel ratio of exhaust gas discharged from the engine 10 and an in-cylinder air amount, and is compared with a fuel amount that theoretically should be injected from the in-cylinder injection valve 28.
