Common rail injection is a modern fuel injection system for diesel engines that ensures high performance, low fuel consumption, and reduced emissions. It has revolutionized diesel technology and is now found in most modern diesel vehicles. This article highlights the functionality, benefits, and common problems of common rail injection.
An efficient injection system is the heart of a modern diesel engine. Common rail injection, unlike older systems, stores fuel under high pressure in a common line – the so-called “common rail”. From there, the fuel is injected precisely and electronically controlled into the individual cylinders. This enables optimized combustion and thus better performance. inlinepumpe
What is Common Rail Injection?
Common rail injection is an electronically controlled injection system that stores fuel under high pressure in a common line, the common rail. The fuel is then injected into the combustion chambers via injectors. The pressure in the common rail is kept constant regardless of engine speed and fuel quantity, which enables precise injection. “The precise control of the injection pressure is the key to the efficiency of common rail technology,” says Dr. Franziska Müller, author of “Modern Diesel Technology.”

Benefits of Common Rail Injection
Common rail technology offers numerous advantages over conventional injection systems. These include:
- Higher Performance: The precise injection allows for better combustion and thus higher performance.
- Lower Fuel Consumption: Optimized combustion requires less fuel, resulting in lower consumption.
- Reduced Emissions: Common rail injection helps to reduce pollutant emissions, especially nitrogen oxides and soot particles.
- Smoother Engine Running: Multiple injections minimize combustion noise and ensure smoother engine running.
- Improved Drivability: The system reacts faster and more precisely to driver demands, resulting in a better driving experience.

Common Problems of Common Rail Injection
Despite its many advantages, common rail injection can also cause problems. Some of the most common issues are:
- Defective Injectors: The injectors are complex components and can be damaged by contaminants in the fuel. fiat motoren
- High-Pressure Pump Issues: The high-pressure pump is another important component of the system and can also fail. e 280 cdi
- Contaminated Fuel: Contaminants in the fuel can damage the entire system. 350 cdi
- Leaks in the System: Leaks in the common rail system can lead to pressure loss and thus to performance losses. 1.6tdi vw
