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 ...

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. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...

Search the web for 'direct fuel injection history' and two prominent results will often materialise: Leon Levavasseur and the Mercedes-Benz 300 SL. Their prevalence is understandable. Levavasseur is ...

However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

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 ...

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 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 ...
