This Final Year Project (FYP) Report is briefly discusses on the research and study of a small engine working principle and the work step for Upgrading and Optimisation a Carburetted Engine to Fuel Injection for Best Fuel Consumption. The main objective of the project is to study about the Electronic Fuel System (EFI) which is a way to reduce the fuel consumption for small engine. This project is putting high expectation on lowest fuel consumption for a prototype, which needs to be run on the farthest distance with one liter of petrol (former target that this project would be used for Shell Eco Marathon Challenge). The challenge for this project is to find the best way to install the EFI system. EFI system is well known by its economical efficiency. EFI is more economical saving compare to carburetor because it can control the volume of fuel for the engine used, depending on the situation, performance and need of the engine with helped from several sensors. This conversion will greatly improve the engine reliability, consistency and ultimate fuel consumption. The research was undergoing several steps to understand the behavior of the engine, trial runs were done for several engine speeds to know the fuel rate and specific fuel consumption. Alternative fuelling system and parts that needed to be modified had been designed. Lab testing was done for the designed EFI system in order to create the suitable match between the engine and the fuel injection system.
