Gasoline Direct Injection Engine (GDI)

Gasoline Direct Injection Engine (GDI)

ABSTRACT

The Gasoline Direct Injection Engine (GDI) is also known as the Direct Injection Stratified Charge Engine (DISC). Until recently, direct injection technology had been applicable only to the quality governed diesel engines. However, Gasoline Direct Injection utilizes the Direct Injection Technology for Gasoline i.e., Petrol engines.

This technology is so named because the fuel, petrol, is directly sprayed into the combustion chamber after the compression stroke instead of being sprayed through the inlet valve during the inlet stroke.

This paper explains he concept and the working of this technology.

It also explains the advantages of Gasoline Direct Injection over Multi Port Fuel Injection (MPFI). Also explained are the solutions that can be used to optimize the Gasoline Direct Injection engine in order to counter its limitations.
