Diesel Pump Injectors

So what does a diesel fuel injection pump do? It's about as simple as you can get: fuel injectors supply fuel to the engine's internal combustion chamber. High-performance automobiles usually have one fuel injector per cylinder, and the pump “injects” fuel into the combustion chamber – hence the name “fuel injector.”

How does a diesel injector pump work?

The first is an in line injection pump, which means that each cylinder in the engine has pump and a plunger combination connected to it. When the diesel fuel is put into the pump, one end allows the fuel to move into the chamber where the combustion will take place and the other end is where the plunger is located.

What causes injector pumps to fail?

One of the major reasons for injector pump failure is an excessive buildup of deposits. There are two types of deposits – internal injector deposits and external injector deposits. External injector deposits are caused by fuel that's not wholly burned that often builds up around the injector holes.
