高压共轨燃油直喷(Common rail direct fuel injection)是汽油机与柴油机的一种燃油直喷技术。对于柴油机,燃油压力高达1,800 bar或180 MPa或26,000 psi并用单个电磁阀向油轨供油。第三代共轨技术使用精度跟高的压电技术,燃油压力可高达3,000 bar(300 MPa;44,000 psi)。汽油机使用汽油直接喷射技术。

Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines.

On diesel engines, it features a high-pressure (over 1,000 bar or 100 MPa or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to 3,000 bar (300 MPa; 44,000 psi).
