Techniquement similaire à l'injection des moteurs diesel, la technologie de l'injection directe de carburant dans la chambre de combustion nous promet une amélioration de la consommation ainsi qu'une ...

Le groupe de travail "Mobilités et transports" de la commission du développement durable du Sénat, chargé d'étudier l'impact sur la santé et l'environnement des émissions des véhicules diesel récents ...

How does direct fuel injection work? Instead of having injectors in a throttle body, or in the intake manifold, a direct injection system makes use of an injector that fires into the combustion ...

Depuis son ouverture en 1984, l'usine Siemens VDO de Foix n'avait certainement jamais vu autant de journalistes spécialisés débarquer en même temps sur son site. Journalistes de magazines spécialisés, ...

A retrofit system that converts diesel engines to operate on 90% hydrogen has been prototyped and tested by University of South Wales (UNSW) researchers. This system drastically reduces emissions of ...

The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind ...

The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smooth. Simultaneously, the pump also controls the amount ...

Gasoline direct injection (GDI) continues to be a weapon in the technology armoury of automakers in their fight to reduce CO2. Manufacturers believe that homogeneous applications of GDI will be ...

Diesel engines operate at higher compression ratios than gasoline engines, and fuel is injected under much higher pressure. An injection pump, usually driven by a belt or chain linked to the ...
