Common Rail Injector Services

Diesel Repair Shop

As any diesel engine owner knows, the fuel injection system is the heart of the entire operation. While there are multiple types of fuel injector systems, one that is lauded almost universally and oft utilized is the common rail fuel injector. The highly-trained technicians at RPM Diesel have offered swift and expert common rail injector services and our breadth of knowledge to South Florida diesel owners for many years. 

What Is A Common Rail Fuel Injector?

A common rail fuel injector is actually a network consisting of a few different components. As fuel leaves the fuel tank, it enters into the first of these components: the high-pressure pump. The fuel is pressurized inside the cp3 pump before entering into the rail. The rail itself is a complex piece of equipment. It not only feeds fuel into the injectors but it also further checks and regulates fuel pressure using a pressure sensor. Proper pressurization is crucial. Fuel should enter into the injectors as a mist as this results in the safest and most efficient combustion. Pressurization of the fuel ensures it is a fine and consistent mist. Once the fuel leaves the namesake rail and is atomized within the injectors, combustion occurs and the resulting heat energy is used to power the vehicle or vessel.  

Why Common Rail? 

So why opt for a common rail fuel injection system in the first place? Common rail injectors are often described as “cleaner”. This is due to a few different factors that all amount to one thing: Common rail fuel injection uses less fuel on average. When the fuel is atomized, there is a much higher surface area. This results in more effective combustion, as no fuel is being wasted. Common rail systems also supply fuel directly to the area of combustion (the injectors). With low-pressure injection systems, there are many tanks and filters the fuel must pass through in order to reach the injectors. This causes volume loss as the fuel travels through the system. 


All of this results in a diesel engine that produces significantly less noise and emissions. Along with increased fuel efficiency, this makes common rail diesels far superior to their predecessors and much less of a hassle for the owner.
