燃料噴射装置。[Scope of Claim for Utility Model Registration] A fuel injection valve that injects fuel into an intake passage every predetermined set period, a fuel pump that supplies fuel to the fuel injection valve at a predetermined pressure, a fuel pump and a fuel injection valve, an adjusting means that adjusts the fuel pressure to the fuel injection valve to an arbitrary set pressure; a first detecting means that detects the rotational speed of the engine; and a second detecting means that detects the shift position of the transmission. and when the first detection means detects that the engine speed is in a high rotation region, the set pressure in the adjustment means is adjusted regardless of the shift position detected by the second detection means. Set to a high pressure,
If the second detection means detects that the shift position is a position that allows a rapid increase in engine speed, the set pressure in the adjustment means is set to a higher pressure regardless of the engine speed. What is claimed is: 1. A fuel injection device for an engine, characterized in that it comprises a setting means for setting.
