Auto Correct | Gasoline Direct Injection (GDI)

Gasoline direct injection (GDI), also known as petrol direct injection (PDI), is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber.

The use of GDI can help increase engine efficiency and specific power output as well as reduce exhaust emissions. https://en.wikipedia.org/wiki/Gasoline_direct_injection
