摘要:
An engine fuel injection control apparatus has a parameter setting section, a parameter changing section and a determining section. The parameter setting section is configured to set a parameter of fuel injected into an engine to a first injection parameter to control a state of combustion noise or exhaust emission to a target state when an engine operation condition is in a first operation region. The parameter changing section is configured to change the parameter of fuel injected into the engine from the first injection parameter to a second injection parameter while the engine operation condition remains in the first operation region. The determining section is configured to determine whether or not an actual state of the combustion noise or the exhaust emission of the engine changes when the parameter of fuel injected into the engine is changed from the first injection parameter to the second injection parameter.
摘要(中):
发动机燃料喷射控制装置具有参数设定部,参数变更部以及判定部。 参数设定部被配置为当发动机运转状态处于第一运转区域时,将喷射到发动机的燃料的参数设定为第一喷射参数,以将燃烧噪声或废气排放的状态控制在目标状态。 所述参数变更部构成为,在所述发动机运转状态保持在所述第一运转区域的状态下,将从所述第一喷射参数向所述发动机喷射的燃料的参数改变为第二喷射参数。 确定部分被配置为当喷射到发动机中的燃料的参数从第一喷射参数改变到第二喷射参数时,确定燃烧噪声的实际状态或发动机的排气发射是否改变。
