Abstract

Single cylinder 4 stroke engine usually use carburettor for the fuel system. Tuning carburettor to get the right amount of fuel for different engine operating condition is not easy. Comparing with Electronic Fuel Injection System (EFI), carburettor has high fuel consumption, produces less power, leads to fuel delivery instability and affects the drivability of the vehicle. The study is conducted to show that EFI system produce better performance than carburetted system for the single · cylinder 4 stroke engine. The study is done by using engine simulation software, (iT POWER. Carburetted engine model is built in GT POWER and validations are being made with previous testing and simulation data. The carburetted model is then converted to EFI model. The EFI model is further tuned to improve the engine torque at low speed range. The findings show that EFI system produce better performance than carburetted system. Finding also shows that engine torque at low speed range can be improved by intake length tuning and AFR tuning.
