If you own a big truck or a heavy machine that runs on diesel fuel, then you may have come across a term called common rail injector. It is a small but very important part of the engine but it sounds complicated. This article will define common rail injector nozzle, what making it important to maintain, how does it work, different common issues it may have and how do you replace its parts if needed.
What is a common rail injector nozzle? Automatic gas injection nozzle in a diesel engine. It’s so small you might not notice it unless you know just where to look. Located inside the engine, this nozzle is responsible for assisting with the delivery of fuel to the cylinders of the engine. The nozzle which guides the flow must allow fuel to flow inside the nozzle trims, the nozzle itself is comprised of three distinct parts which include: the nozzle body, the valve assembly along the flow with the spray tip.
Here are some tips for maintaining common rail injector nozzle of your diesel engine. It can create so many issues if it is not well maintained. Perhaps one of the most common issues is that the engine might not perform the way it should. What this means is that the engine may have a hard time starting, smooth running, or even idle.
The common rail injector nozzle injects fuel into the engine's cylinders at high pressure. From the engine's fuel rail, fuel is piped into the nozzle body and supplied at the necessary high-pressure for the engine to operate properly.
After that, the valve assembly inside the nozzle will regulate how much fuel will enter the nozzle once it reaches the nozzle body. Thus when the valve opens the fuel sprayed through the spray tip into the engine's cylinders. Then, in the cylinders, the engine's spark plugs ignite the fuel, producing the energy necessary to power the engine. This bubbling and igniting of the fuel is what allows your vehicle to move and operate correctly.
Just like any other component in an engine, a common rail injector nozzle can fail over a period of time. Clogging is one of the most common issues. Clogging is the state when the dirt and debris gets stuck inside the nozzle body or the spray tip. This can cause the engine performance to drop which means your engine might not run to the level that it should.
You will know check for these defects when your engine is not running that well, is consuming more gas than normal or strange sounds coming from your engine. Breakage of Common Rail Injector Nozzle Flag If you notice any of these things then you may need to check your common railed internal nozzle.
