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 ...

Direct injection, as the name suggests, refers to a type of fuel system which introduces fuel directly into an engine's combustion chambers. This differentiates it from conventional injection systems ...

There are plenty of advantages to diesel engines: High fuel efficiency, low CO2 emissions, and in modern turbocharged applications, plenty of easy-to-access torque and power. However, they aren't ...

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 ...

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 ...

GM's mass-market diesel engine has seen many variations, but these three stand out as the best.

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 ...

The carbureted car and truck era phased out by the early '90s. Carbs are still in use today on a few motorcycles, lawn mowers, and other power equipment, but electronic fuel injection (EFI) is ...

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 ...
