Title:
圧縮着火内燃機関の燃料噴射システム
Document Type and Number:
Japanese Patent JP4826540
Kind Code:
B2
Abstract:
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.
