High-Pressure Fuel Injection Rails (FIRs)製品情報


High-pressure fuel injection rails (FIRs) are used in gasoline direct injection engines, the adoption of which is growing among all automakers, to improve environmental performance.

Accompanying the development of the gasoline direct injection engine in response to strengthening exhaust emission standards and CO2 emission reduction measures, these products were developed to be capable of withstanding high pressures of approximately 50 times the normal fuel pressure.


  1. Uses high-strength cylindrical pipe
    • Excellent high-pressure durability
    • High flexibility of design

Primary Applications

Fuel supply systems for gasoline direct injection engines (piping between the high-pressure pump and the high-pressure injector)
