Fossil fuel which is a non-renewable energy source is ubiquitous in automobiles. The present study aims to introduce a closed-loop electronic fuel injection (EFI) system for a 125 cm3 4-stroke gasoline engine, which tends to efficiently utilize fuel. A compatible prototype was developed and installed to the existing motorcycle engine with the aforementioned specifications in order to carry out experiments. Firstly, same volume of fuel is supplied to the selected engine with three different carburetors which are mechanical, EFI and the modified EFI and the engine was run at the speed of 6000 RPM. Then, the time taken to burn the given fuel volume was measured. Secondly, by using the three carburetors, an emission test was carried out and analyzed the gases emitted by each case. The results of the first test showed that the modified EFI system runs longer time compared to the mechanical system and shows that the system has better fuel economy. Also, the emission tests showed a significant reduction in CO and HC emitted by the modified EFI system compared to mechanical carburetor.
