What Are The Components of an Injector?

There are several parts of a 7.3 Powerstroke injector that combine to improve the working condition of the vehicle. Some major components of an injector include:

Injector Solenoid

There are electromagnetic solenoid controls present in the injector. The injector driver module is responsible for generating an electrical signal to the solenoid that activates the mechanical valve. This controls the diesel fuel and high-pressure oil flow.

Poppet Valve

This valve is responsible for controlling the flow of oil into the injector. For the regulation of this flow, the voltage signals are physically increased or decreased.

Injector Intensifier Piston

The piston and plunger are capable of multiplying the effects of oil pressure on the piston. It normally generates a fuel pressure that is seven times greater.

Injector Nozzles

This is considered the tip of the injector. This nozzle is responsible for spraying the diesel fuel into the chamber.

Injector O’ Rings

These O’ rings play a key role in the injector. These are important for keeping the oil on the oil side and fuel on the fuel side. If they get mixed, there can be an emission of black smoke that could be a big problem.

What to Look for When Buying Injectors

When it comes to 7.3 Powerstroke injectors, there are multiple options available on the market. This makes it difficult for you to get the right one. In order to ease the task, you must look for a few factors in any model before making any purchase, including:


The size of the Powerstroke injector is the most important factor to consider. The right one entirely depends on the use you have in mind. A small sized-injector will not add much power to your vehicle. Meanwhile, a truck requires larger injectors to fulfill the demands of the user. Therefore, you must get an injector by keeping your needs in mind.


Powerstroke injectors can be really expensive. The price of any product is very important to consider. Therefore, you must decide your budget first and then look for the model with all the desired features that lie in your budget as well.


Manufacturers offer a certain warranty on their products in order to mark reliability. Therefore, it is important to go for a model that comes with an impressive warranty in order to save you from the expenditures of repairing.


You must opt for a product that is very easy to install. This will help you avoid calling for professional help, or at least you won’t have to pay much for the installation of the Powerstroke injector.
