An Injection Pressure Regulator (IPR) on a diesel engine is a component that manages the high-pressure oil system, crucial for operating the fuel injectors in engines equipped with hydraulic electronic unit injectors (HEUI). The IPR valve adjusts the oil pressure in the high-pressure oil pump, controlling the timing and amount of fuel injected into the combustion chamber. Proper functioning of the IPR is essential for maintaining engine performance, fuel efficiency, and emissions control.
