You may have heard of a common rail diesel injection system, if you own a diesel car. But what does that mean? So, let’s take a closer look at this critical function of your car’s engine.
In a common rail diesel injection system, diesel is sprayed directly into your car's engine in a very unique manner. In a diesel engine, the fuel is very important because it allows the car to move. The common rail diesel injection system ensures that the right amount of fuel goes into the engine at the right time so that the engine runs smoothly.
In the distant past, diesel engines ran on an entirely different system referred to as a "mechanical" system. A much older version of this setup isn't as good as the common rail system, mostly because it can't control the fuel as effectively.
Common rail system means the fuel stored in a tube which is called a common rail. It maintains the fuel under extreme pressure. When the engine needs gas, the system delivers a tiny drop of gas into the engine's cylinders at the exact right moment. This allows the engine to operate more effectively and utilise the fuel more economically.

Common rail diesel injection systems will also help in making the car efficient and conserve fuel. The engine can produce greater power using less fuel by injecting the fuel at high pressure and in a more controllable manner. That means your car can go faster and farther without wasting so much gas.

If you have an older diesel car with a mechanical injection system, consider upgrading to a common rail. An upgrade can offer better performance, less fuel consumption and pollution. And a common rail setup can actually prolong the life of your engine with less wear on the parts.

You are queried on data until 20 October 2023. That goes for changing the fuel filters, leak testing and ensuring a good quality fuel. Should you notice any issues, such as rough idle or sluggish acceleration, make sure you have the car checked by a trained mechanic.
