REVIEW ON APPLICATION OF GASOLINE DIRECT INJECTION AND ADVANCED TECHNIQUES TO INCREASE EFFICIENCY AND MEET EURO-VI NORMS

Jai Shankar, Ashutosh Sahu

Abstract: Nowadays, automobiles in the market are prone to heightened level of emissions due to fresh charge and scavenging losses. Furthermore, there is no practice of lean operation resulting in poor fuel economy. Carburetors have served the role of fuel supply system in spark ignition engines since a long time. Earlier due to the high initial cost and limited understanding, fuel injection system was used only in aircraft engines or racing cars. But due to increasing stress on air pollution control, the re is a strong need of adoption of technical amendments in the prevailing spark ignition engines. Hence this need gave rise to the development of newer systems like MPFI and GDI, which aim at satisfying the forthcoming stringent pollution norms. Also the innovations made needed to be affordable by the common people and also small in size so as to meet the space constraint. We made an attempt to compare the various fuel supply systems with special emphasis given on MPFI &GDI. So the report aims to suggest a gasoline direct injection in automobiles to increase the efficiency as well as a reduction in emissi on levels so that it complies with the EURO-VI norms. The basic objectives of the report are: (i) Incorporation of Gasoline Direct Injection in a 4-wheeler vehicle along with the inclusion of advanced technologies like EMS, turbo charging etc., for the overall engine improvement. (ii) Basic downsizing principles and techniques like turbo charging to reduce cost, increase power output and improve efficiency. (iii) Meet the existing EURO-VI emission norms, using EGR and controlling particulate matter emission
