GASOLINE DIRECT INJECTION ( GDI )

Sari

Ianjection sistem early was used in diesel vehicles, furthermore with technology development it is applied in gasoline vehicles. Because of its precision and stability consistency of injection of fuel reaching microsecond dimension in every compression step and Learn-Burn process so able to burn much air and few fuel, therefore the fuel is more frugal. Gasoline Direct Injection or combustion engineering frequently called as Direct injection stratified charge combustion. This stratified combustion sistem controls mixture
in combustion space. Value of ratio between fuel and air in wich gas can be burn or not, it is called as flamability limit, whereas air flow is used to direct the mixture to sparkplug location wherein combustion will be started. This combination is very imfortant for resulting stable combination, with the result that tuning between these factors become a key of combination quality.
