The Common Rail is a fuel injection system used in modern diesel engines. This system has revolutionized the automotive and marine industry by providing combustion efficiency and reduction of pollutants without compromising engine power.

In a traditional diesel engine, fuel is injected directly into the compressed air inside the combustion chamber. However, the Common Rail changes this equation. In this system, the fuel is stored in a high-pressure tank, called a rail, and then injected directly into the combustion chamber through an injector.

The Common Rail works by using an electronic control unit that regulates the amount of fuel injected and the timing of injection. This allows for optimal combustion and a reduction in exhaust gas emissions.

The injectors used in the Common Rail system are also much more advanced than those used in traditional diesel engines. Injectors can inject fuel at high pressure and with great precision. This means that better fuel atomization, more efficient combustion, and reduced exhaust gas emissions can be achieved.

The Common Rail was developed in the 1990s by the Italian company Fiat Powertrain Technologies. However, the system was quickly adopted by other automotive and marine companies worldwide. Today, the Common Rail system is an industry standard used in a wide range of applications, from cars to high-speed trains.

In summary, the Common Rail system is an innovative technology that has improved the efficiency of diesel engines and reduced pollutant emissions. This system is an example of how technology can be used to improve efficiency and reduce the environmental impact of internal combustion engines.
