    • A fuel injection control apparatus for an internal combustion engine includes a fuel injection portion that performs each of first fuel injection for performing stratified-charge combustion, and second fuel injection for performing homogeneous-charge injection; and an injection distribution ratio control portion that controls an injection distribution ratio. The injection distribution ratio control portion controls the injection distribution ratio to a target injection distribution ratio (Atgt) set based on a predetermined engine condition after start of the engine. An initial injection distribution ratio (Ai) is set based on an engine condition at a time of start of the engine, and a change in the injection distribution ratio is controlled by referring to the engine condition after the start of the engine, when the injection distribution ratio is changed from the initial injection distribution ratio (Ai) to the target injection distribution ratio (Atgt).
    • 一种用于内燃机的燃料喷射控制装置,包括:进行各自进行分层充气燃烧的第一燃料喷射的燃料喷射部和进行均匀充电喷射的第二燃料喷射; 以及控制喷射分配比的喷射分配比控制部。 喷射分配比例控制部将喷射分配比控制为基于发动机起动后的预定发动机状态而设定的目标喷射分配比(Atgt)。 基于发动机起动时的发动机状态来设定初始喷射分配比(Ai),并且通过参照发动机起动后的发动机状态来控制喷射分配比的变化,当喷射 分配比率从初始注入分配比(Ai)改变为目标注入分配比(Atgt)。

    • In a predetermined low-temperature startup state (in a rich atmosphere), in principle, over-advanced ignition control for advancing ignition timing beyond MBT and intake-synchronized injection control for causing the entire amount of to-be-injected fuel to undergo intake-synchronized injection are executed. Thus, the peak of intra-cylinder temperature increases, and the amount of port-adhering fuel decreases, whereby the emission amount of unburnt HC can be reduced. However, when the PM emission amount exceeds a PM permissible amount, instead of the intake-synchronized injection control, there is performed processing for causing a portion of the to-be-injected fuel to undergo intake-unsynchronized injection and causing the remaining fuel to undergo intake-synchronized injection. Thus, the amount of intra-cylinder-adhering fuel decreases, and the partial oxidation reaction of the intra-cylinder-adhering fuel, which is a cause of generation of PM, is suppressed. As a result, the PM emission amount decreases, whereby the PM emission amount can be suppressed to the PM permissible amount.
    • 在规定的低温起动状态(浓空燃比气氛下)中,原则上为了使点火正时超前于MBT而进行过度提前点火控制,以及使全部量的被喷射燃料进行吸气同步喷射控制 执行同步注射。 因此,缸内温度的峰值增加,并且端口附着燃料量减少,由此可以减少未燃HC的排放量。 但是,在PM排放量超过PM容许量的情况下,代替进气同步喷射控制,进行使喷射的燃料的一部分进行非同步喷射,并使剩余的燃料成为 进行进气同步注射。 因此,缸内附着燃料的量减少,并且抑制了作为PM产生的原因的缸内附着燃料的部分氧化反应。 结果,PM排放量减少,由此可以将PM排放量抑制到PM容许量。
