摘要：Fuel injection system is a promising technology that enhances positively the fuel economy, engine performances and emission reduction, as compared to the conventional carburetor system.Currently, motorcycles using carburetor system are widely used as a mean of transportation especially in urban areas.This conventional fuelling system produces more harmful emissions and consumes more fuel compared to the fuel injection system.It is therefore desirable to have a fuel injection system that can easily be retrofitted to the current on-road motorcycles.This paper presents a review and comparative study using 1-D simulation software - GT-Power, on electronic fuel injection (EFI) system between port-fuel injection (PFI) and direct injection (GDI) system for retrofitment purpose of small 125cc 4-stroke gasoline engine.From this study, PFI system has been selected based on its high brake power, brake torque, and brake mean effective pressure with low brake specific fuel consumption.
