English

Subject field(s)
  • Climate Change
  • Climatology
CONT

TEWI is the sum of the direct(chemical) and indirect(energy) emissions of greenhouse gases from the operation or use of a CFC or fluorocarbon system for its useful life.

French

Domaine(s)
  • Changements climatiques
  • Climatologie
DEF

Somme des effets directs et indirects des émissions de gaz à effet de serre sur toute la durée de vie d'un équipement donné.

Spanish

Campo(s) temático(s)
  • Cambio climático
  • Climatología
CONT

Para valorar además el efecto calentamiento hay que valorar otro efecto indirecto derivado del consumo de energía con liberación de CO2, tanto si es de origen térmico como eléctrico. La combinación de ambos efectos directo e indirecto, se conoce como TEWI (efecto de calentamiento total equivalente).

Record 3 2004-12-10

English

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

French

Domaine(s)
  • Moteur (Véhicules automobiles)
DEF

Moteur à combustion interne dans lequel le carburant est injecté sous pression directement dans la chambre de combustion.

OBS

À noter que les moteurs à injection directe peuvent utiliser du diesel ou de l'essence.

Subject field(s)
  • Air Pollution
CONT

These indirect effects [of automotive emissions] include the formation of photochemical oxidants from primary emissions of hydrocarbons and nitrogen oxides in the presence of sunlight and the formation of nitrates and nitric acid from emissions of nitrogen oxides. The end products all have known or suspected adverse effects on various receptors.
