    • A fuel injection control device for a more stable carburetion condition by setting an adequate fuel injection prohibition period at the start of an internal combustion engine. A fuel injection control device includes an injection switch which selectively switches among simultaneous injection which is performed after start of cranking in an engine until determination of a crank reference position, group injection which is performed after determination of a crank reference position until completion of stroke identification, and sequential injection which is performed after completion of stroke identification. The maximum period from simultaneous injection, after start of cranking, until simultaneously injected fuel is sucked into all cylinders #1 to #4 is set as an injection prohibition period t. The injection prohibition period t prevents “double injection,” if group injection is started just after determination of a crank reference position and “injection failure,” if the injection prohibition period is too long.
    • 一种燃料喷射控制装置,用于通过在内燃机的启动时设定足够的燃料喷射禁止期,来实现更稳定的化油条件。 燃料喷射控制装置包括:喷射开关,其选择性地在发动机起动之后执行的同时喷射之间切换,直到确定曲柄基准位置,在确定曲柄基准位置之后执行的组喷射直到行程识别完成 ,以及在笔划识别完成之后执行的顺序注入。 将同时喷射,开始起动之后,直到同时喷射的燃料吸入所有气缸#1至#4的最大时间段被设定为喷射禁止期间t。 如果喷射禁止期间太长,喷射禁止期间t如果在确定曲柄基准位置之后开始组喷射和“喷射失败”,则防止“双重喷射”。
