ABSTRACT
Fuel efficiency and emission control are geared toward energy-saving policy and environmental protection respectively. Modification of conventional fuel metering systems such as carburetors has been identified as a step forward in achieving this objective. The rationale behind this review is to have basic knowledge of the choice of engine suitable for retrofitting for enhanced engine efficiency and combustion improvement. In particular, a motorcycle engine using a traditional carburetor is retrofitted with a fuel-injection unit by swapping out the carburetor and manifold sections while retaining traditional parts such the engine and the electrical systems, this optimizes the air mass flow rate into the engine at a given time to mix with the correct amount of gasoline so that the amount of fuel produced is accurate for complete combustion and emission reduction. This review concludes that by retrofitting (FIS) into the existing engines to replace carburetors, the new technology is capable of saving cost, increasing fuel efficiency, and reducing exhaust emissions.
