Fuel Injection Rail Assembly
Mitsubishi FUSO®

The Fuel Injection Rail Assembly, also known as the fuel rail, is a crucial component of a commercial truck's fuel system. It is responsible for delivering fuel to the engine's fuel injectors, which then atomize the fuel and spray it into the engine's combustion chamber. The fuel rail is a long, narrow pipe that is mounted on top of the engine's intake manifold and is connected to the fuel injectors via small hoses or tubes. The fuel rail is typically made of high-quality materials such as aluminum or stainless steel to withstand the high pressures and temperatures of the fuel system. The Fuel Injection Rail Assembly plays a vital role in ensuring that the engine runs smoothly and efficiently. It is designed to regulate the fuel pressure and flow rate to the injectors, which helps to optimize the engine's performance and fuel economy. A faulty fuel rail can cause a variety of problems, including rough idling, poor acceleration, and decreased fuel efficiency. Therefore, it is important to ensure that the Fuel Injection Rail Assembly is properly maintained and replaced as needed to keep the engine running at its best.
