发动机的燃料喷射控制装置
摘要：
一种发动机(1)燃料喷射控制装置，所述发动机具有将燃料喷射入气缸(C)的直接喷射器DI和将燃料喷射入进气通道(31)的进气道喷射器(PI)。在发动机空转时，控制装置降低目标发动机速度，同时避免发动机失速。在发动机空转时，燃料喷射控制装置通过直接喷射器和进气道喷射器向发动机供给燃料。电子控制单元(9)确定在发动机空转时是否存在发动机失速的可能性。在确定存在这样的可能性时，电子控制单元增加直接喷射器的燃料喷射量。
摘要（英）：

A fuel injection controller for an engine having a direct injector for injecting fuel into a cylinder and an intake injector for injecting fuel into an intake passage. When the engine is idling, the controller reduces a target engine speed while preventing the engine from stalling. The fuel injection controller supplies fuel to the engine through the direct injector and the intake injector when the engine is idling. The electronic control unit determines if there is a possibility of the engine stalling when the engine is idling. When having determined that there is such a possibility, the electronic control unit increases the fuel injection amount of the direct injector.
