Each injector features improved end cap assemblies to help fix cold start issues. The nozzle flow testing process gives the injector a like-new performance.
In the auto aftermarket the term "remanufactured" refers to parts that have been completely remanufactured to the standard of being like new. For those sensitive to environmental concerns, it's useful to know that remanufactured parts use 80% less energy than manufacturing parts from scratch. The process also conserves raw materials.
XDP fuel injectors include all new connectors, O-rings, internal hardware, and springs, with the intensifier body and plunger matched to eliminate fuel dilution. A precision matched control valve and spool help to minimize oil leakage and maximize power output.

Fuel injectors are small electrical components that are used to deliver fuel via a spray directly into the intake manifold in front of the intake valve in a diesel engine.
Diesel fuel injectors are quite complicated. The injector has a high micron filter on the top inlet side which corresponds to small hypodermic sized holes on the bottom for the atomizing of the diesel fuel.
The diesel fuel acts as a lubricating source for the injector’s internal parts. The main source of failure for injectors is water in the fuel. When water in the fuel displaces the lubricating properties the internal parts wear down and can quickly fail.
Injectors are an extremely important engine component. The injector valve opens and closes at the same rpm as the diesel engine. Typical RPM for diesel engines in North America is around 1800. This equates to roughly 140,000 times per hour! In addition to water in the fuel, injectors are subjected to carbon and dirt particles introduced into the unit via a bad air cleaner element.
The type of fuel, grade and additives used also has a significant impact on the life expectancy of the fuel injector. The Engine Control Module (ECM) controls the fuel injectors in most electrical diesel engines. The diesel injectors constantly have power when the key is turned on regardless if the engine is turned over.
The ECM grounds the injector, completing the circuit and causing the injector nozzle to open. The ECM after receiving information from various control sensors determines the length of time the injectors need to be grounded to inject the exact amount of fuel given the horsepower output demand from the engine.
The process of diesel injectors opening, closing, and dispensing the correct amount of fuel happens in milliseconds. Injector cycle firing is on average completed in 1.5 to 5 milliseconds.
Diesel fuel injectors come in different shapes and sizes depending on the engine make and model as well as power demand. Automotive injectors are quite a bit smaller than heavy-duty diesel applications and are measured in cubic inches.
There are two types of diesel fuel injectors: the first is called throttle body injection where 1-2 injectors are in the throttle body itself in the diesel engine and supply a metered amount of mist fuel spray into the intake manifold. The second delivery system, known as individual port type fuel injector, is newer and more fuel efficient.
