Abstract


Fuel prices are increasing continuously all over the world. Also, globally the vehicle density is increasing according to geometric progression which contributes as a major source of air pollution. Therefore, improvement is continuously demanded in design of an efficient engine producing less harmful emissions. Many researcher and engine manufacturers in this field are optimistic and enthusiastically working to achieve these objectives. This work mainly focuses on   low cost electronic fuel injection (EFI) system developed for a small two stroke SI engine. Engine mapping plays vital role to reduce emissions and enhance engine performance by providing appropriate amount of fuel quantity at all operating conditions of engine which results in complete combustion.  This paper presents the experimental work using engine mapping process with EFI system, graphical user interface based software – Proteous and modified fuel injection system. The experimental results of carburetor mode and EFI mode are included and compared.
