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 ...

The common-rail fuel injection system does away with a timed injection pump. Instead a single output pump supplies a fuel “rail” – a reservoir of fuel held at pressures of between 400 and 1400 bar ...

High pressure common rail system can precisely control the injection time and injection pressure to improve the thermal efficiency of the engine. The injection characteristics of the system can affect ...

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 ...
