Diesel Fuel Injection Pumps – Quick Overview
So what does a diesel oil injection pump do? It’s about as simple as you'll get: fuel injectors supply fuel to the engine’s combustion chamber. High-performance automobiles usually have one fuel injector per cylinder, and therefore the pump “injects” fuel into the combustion chamber – hence the name “fuel injector.”
The pressure-Packed fuel injection system
Today’s diesel oil injection pumps are struggling – even more pressure than what was once considered “normal.” Around 15-20 years ago, it had been common for fuel injector pumps to process fuel during a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half what engines are expected to try to today.
