SMALL ENGINE PERFORMANCE OPTIMIZATION FOR POWER AND FUEL CONSUMPTION IMPROVEMENT OF A SIMPLE VEHICLE

This report discusses the preliminary research done and basic understanding of the
chosen topic, which is Small Engine Performance Optimization for Power and Fuel
Consumption Improvement of a Simple Vehicle. The objective ofthe project is to find
the optimum engine performance of a single cylinder engine which suggests utilizing a
minimum amount of petrol without compromising the performance of the engine. The
challenge in this project is to find the most suitable way to install the EFI (electronic fuel
injection) and to calibrate the EFI module to work efficiently at different conditions. The
reason to change the standard carburetor with an EFI system is to obtain more fuel
efficiency and power improvement because it is proven that better fuel and air supplying
into the intake manifold will give the engine more power and fuel efficiency. An EFI
system provides correct mixture of fuel and air compare to the carburetor with the help of
electronic system thus it increased engine performance. Lab testing was performed for
the designed EFI system to create the suitable match between the engine and the fuel
injection system. The system was tested for its workability, performance and resistance to
high performance condition. The result from the experiment shows an improvement of 3
to 4% of improvement of fuel consumption. Further detail can be read in this report.
