Diesel engines create power with fuel and high-pressure air. Special to Ford Powerstroke diesel engines, the injection pressure regulator (IPR) valve maintains a working oil pressure of 3,000 to 4,000 PSI in the high-pressure oil pump (HPOP). The IPR valve works with other crucial components of the engine’s hydraulic electronic unit injection (HEUI) system. It …
Over the years, carmakers have made many changes in their manufacturing processes and components to mitigate harmful emissions and comply with global standards. One example is the introduction of the exhaust gas recirculation (EGR) valve. This component reduces toxic gas emissions by redistributing a portion of the engine’s exhaust gases back into the engine cylinders. …
The valve body plays an essential part in your vehicle’s function, ensuring the appropriate flow of transmission fluid through vital system components. When the valve body cannot maintain fluid pressure, it can lead to more severe transmission problems. Explore the signs of a bad valve body, potential causes and how you can solve these problems. …
