Fuelling system is one of the crucial variables that must be focused on, in order to achieve good fuel efficiency and low engine out emissions. Fuel injection system seems a promising technology as a medium to supply suppressed fuel because of its high fuel delivery efficiency, enhanced fuel economy and reduced engine out emission. Port-fuel injection (PFI) system has been used widely on small four-stroke gasoline engine because of its simplicity compared to direct injection (DI) system. In this study, the effects of intake manifold angle of a PFI retrofit-kit to the engine performances and emission characteristics were investigated. Experimental works comprised wide-open throttle with variable dynamometer loads for two different angles: 90° and 150°. From this study, it was observed that 150° was the optimum angle, which produced high brake power (BP) and brake mean effective pressure (BMEP), brake specific fuel consumption (BSFC) and hydrocarbon (HC) emission.
