GDi stands for "gas direct injection" and refers to how the engine injects gas into the cylinders. In any internal combustion engine, fuel is sprayed into the air to create a mixture of fuel and air.

With gasoline direct injection (GDI) engines, the air/fuel mixture is formed directly in the combustion chamber. No concern is needed for how effectively the fuel atomizes or flows through the ...
