A fuel rail is a component in a fuel injection system that is responsible for distributing fuel to the injectors. It is typically a hollow metal tube that runs parallel to the engine's cylinders, and is connected to the fuel pump and fuel filter on one end, and to the injectors on the other.

The fuel rail is the common reservoir of high pressure fuel that feeds into all the injectors on one side of a fuel-injected engine. Fuel is pumped into one end, and as each injector is triggered in sequence, they spray fuel at a consistent pressure.

A fuel rail is a high-pressure fuel line that properly supplies fuel to the fuel injector in an IC engine. It is a vital part of the fuel injection system and is essential for the stable fuel supply to the injector.

Nov 2, 2024 · Fuel rails play a critical role in delivering fuel to the engine’s injectors, ensuring optimal performance and efficiency. They function through a series of well-coordinated processes that guarantee that the right amount of fuel reaches each injector at proper pressure.

The fuel rail supplies the injectors with fuel with minimal pressure fluctuations between individual injections.

The fuel rail supplies fuel to the fuel injectors mounted directly on the fuel rail. That the fuel is available at the required injection pressure at the start of injection and only minimal pressure fluctuations occur between the individual injections is key.
