(Redirected from Gasoline Direct Injection)
Gasoline Direct injection or GDi is a variant of fuel injection employed in modern two- and four- stroke petrol engines. The gasoline is highly pressurised, and injected via a common rail fuel line directly into the combustion chamber of each cylinder, as opposed to conventional multi-point fuel injection that happens in the intake tract, or cylinder port. GDi enables stratified charge (ultra lean burn) combustion for improved fuel efficiency and emission levels at low load.
