Gasoline direct injection:
GDI is a variant of fuel injection employed in modern four stroke petrol engines. The gasoline or petrol is highly pressurized, and injected via a common rail fuel line directly into the combustion chamber of each cylinder.
SYSTEM
Fuel pump: fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank. And some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine.
High Pressure lines:
This tube or pipe connects pump to the common rail. The pipe assembly transports fuel at high pressure between pump, rail and injectors, remains completely sealed and resistant to pressure changes.
