common-rail method

The common-rail method is a fuel injection system used in diesel engines. It features a single fuel line, known as a common rail, that supplies fuel under high pressure to all the cylinders. This system is crucial for the efficient operation of diesel engines, which convert chemical energy from fuel into mechanical energy to power various vehicles and machinery.12

In a diesel engine, air is compressed to a high temperature, and then fuel is injected. The common-rail system precisely controls the timing and pressure of this fuel injection, which is essential for combustion. This technology allows diesel engines to achieve high efficiency and power output.2
