Common Rail
Common rail direct fuel injection is a modern variant of direct fuel injection system for petrol and diesel engines.
On diesel engines, it features a high-pressure (over 1,000 bar or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to low-pressure fuel pump feeding unit injectors (Pumpe/Düse or pump nozzles). Third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to 1,800 bar or 26,000 psi.
In gasoline engines, it is used in gasoline direct injection engine technology.

Famous quotes containing the words common and/or rail:
“I think what everybody calls a miracle is just common sense.... You can look at the attitudes when people come in. That’s why they call it a miracle. These are black kids and they’re not supposed to know the things they know and achieve the way they are achieving.”
—Marva Nettles Collins (b. 1936)
“Old man, it’s four flights up and for what?
Your room is hardly any bigger than your bed.
Puffing as you climb, you are a brown woodcut
stooped over the thin rail and the wornout tread.”
—Anne Sexton (1928–1974)
