Subject field(s)
  • Fixed Rescue Facilities (fire)
CONT

A fire sprinkler system shall be provided that will automatically shut-off the water supply flow control valve when the fires heat source has been controlled and a soak timer has expired. If the fires heat source was to regenerate, the fire sprinkler system shall automatically reopen. This cycling feature of the sprinkler system shall not be dependent on manual supervision. Cycling fire sprinkler system shall be a closed head type of preaction system with a supplemental detection system which will activate flow control valve.

CONT

Cycling sprinkler. A development by the sprinkler industry is a sprinkler that cycles on and off as needed.... Under normal conditions, the pilot valve is held closed by the snap disc. Water in the piston chamber holds the piston closed. When the snap disc is heated to the rated temperature, it opens the pilot valve and releases the water from the piston chamber. This allows the piston to open and water to flow from the sprinkler. When the snap disc cools to approximately 100°F, it closes the pilot valve.

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.

French

Domaine(s)

Subject field(s)
  • Engines (Motor Vehicles)
OBS

Direct injection(DI) refers to fuel injected directly into the combustion chamber above the piston. Direct injection has long been used on large diesel engines. Smaller diesels are increasingly adopting direct injection(vs. indirect injection into a pre-chamber). Direct injection also can be used in spark ignition(generally gasoline) engines instead of port fuel injection-for cleaner emissions, increased full throttle power and potentially for lean-burn operation.

Key term(s)
  • direct-injection engine

  • Moteur (Véhicules automobiles)
