INITIAL CHAMBER [8 records]

Record 1 2005-09-19

English

Subject field(s)
  • Diesel Motors
  • Engines (Motor Vehicles)
CONT

In an indirect injection diesel engine, fuel is injected into a small prechamber which is connected to the cylinder by a narrow opening. The initial combustion takes place in this prechamber. This has the effect of slowing the rate of combustion, which tends to reduce audible noise. In a direct injection diesel engine, fuel is injected directly into the cylinder. The piston incorporates a depression(often toroidal) which is where initial combustion takes place. Direct injection diesel engines are generally more efficient than indirect injection engines, but have a tendency to produce greater amounts of audible noise. In either case the location where combustion takes place, called a swirl chamber, is carefully designed to ensure adequate mixing of the atomized fuel with the compression-heated air.

CONT

Le fonctionnement du moteur Diesel à injection directe est entièrement basé sur l'auto-allumage du combustible dans l'air fortement chauffé par la compression.
