Abstract
(EN)
Provided are: an internal combustion engine system with which the effects on engine performance caused by changes in the combustion characteristics of fuel introduced into an engine can be suppressed; a vehicle; and a spark plug ignition timing correction method. In the internal combustion engine system, natural gas is supplied as fuel to a cylinder and is ignited and combusted by means of a spark plug, wherein the system comprises a control unit that corrects, on the basis of the temperature of the fuel, the timing for ignition by the spark plug. Further provided, for example, is a fuel temperature sensor that detects the temperature of the fuel. The control unit corrects the ignition timing on the basis of the fuel temperature detected by the fuel temperature sensor.

L'invention concerne : un système de moteur à combustion interne avec lequel les effets sur les performances du moteur provoqués par des changements des caractéristiques de combustion du carburant introduit dans un moteur peuvent être supprimés ; un véhicule ; et un procédé de correction de synchronisation d'allumage de bougie d'allumage. Dans le système de moteur à combustion interne, du gaz naturel est fourni en tant que combustible à un cylindre et est allumé et brûlé au moyen d'une bougie d'allumage, le système comprenant une unité de commande qui corrige, sur la base de la température du carburant, la synchronisation pour l'allumage par la bougie d'allumage. L'invention concerne en outre, par exemple, un capteur de température de carburant qui détecte la température du carburant. L'unité de commande corrige la synchronisation d'allumage sur la base de la température de carburant détectée par le capteur de température de carburant.
