Title
(EN) Control apparatus for internal combustion engine
(ZH) 用于内燃机的控制设备
Abstract
(EN)
An engine ECU executes a program including the steps of: calculating a fuel injection ratio of an in-cylinder injector (S100); calculating an amount of spark advance using a first map employed when the in-cylinder injector has a fuel injection ratio of one, said first map providing a timing of ignition with a maximum amount of spark advance (S220); calculating an amount of spark advance using a second map employed for a fuel injection ratio of zero, said second map providing a timing of ignition with a minimum amount of spark advance (S230); and calculating an amount of spark advance using a third map employed for a fuel injection ratio larger than zero and smaller than one, said third map providing a timing of ignition with a larger amount of spark advance for a larger ratio (S240).

发动机ECU执行包括以下步骤的程序:计算缸内喷射器的燃料喷射比率(S100);使用当缸内喷射器具有为一的燃料喷射比率时采用的第一图来计算点火提前量,所述第一图提供了具有最大点火提前量的点火正时(S220);使用当燃料喷射比率为零时采用的第二图来计算点火提前量,所述第二图提供了具有最小点火提前量的点火正时(S230);并且使用当燃料喷射比率大于零并小于一时采用的第三图来计算点火提前量,所述第三图对于更大的比率提供具有更大点火提前量的点火正时(S240)。
