FUEL INJECTION CONTROL APPARATUS

The invention discloses a fuel injection control apparatus. When a rotational speed of an engine is higher than a predetermined rotational speed, a low-pressure fuel injection valve is controlled through the use of a fuel injection time based on an estimated fuel pressure in a low pressure supply pipe and a target fuel injection amount. When the rotational speed of the engine is equal to or lower than the predetermined rotational speed, the low-pressure fuel injection valve is controlled through the use of a fuel injection time based on a detected fuel pressure input from the fuel pressure sensor from the issuance of a command to activate energization of a solenoid to the start of energization of the solenoid and a target fuel injection amount. 一种燃料喷射控制装置。在发动机的转速超过预定转速时，使用基于所推定的低压供给管的燃压和目标燃料喷射量的燃料喷射时间来控制低压燃料喷射阀，在发动机的转速为预定转速以下时，使用基于在从做出电磁线圈的通电接通指令起到对电磁线圈通电为止的期间中从燃压传感器输入的检测燃压和目标燃料喷射量的燃料喷射时间来控制低压燃料喷射阀。
