The Fuel Injection Pump Rack Stop Screw is used to mechanically restrict the movement of the rack inside a fuel injection pump. By defining the rack’s maximum stroke, it sets the upper limit for fuel delivery to the engine cylinders. This control mechanism helps maintain engine performance, fuel efficiency, and emissions compliance. The screw threads into the pump housing and is adjusted during engine calibration.Attributes:• Helps maintain consistent fuel injection quantity.• Controls maximum fuel delivery to prevent engine overload.• Stable under high-temperature environments.Applications: The Fuel Injection Pump Rack Stop Screw sets the rack limit inside the fuel pump to prevent over-fueling and maintain engine performance consistency.
