Analysis of performance characteristics on a motorcycle with an external air induction system.

A supercharger is a compressor that is powered by the bike's battery's electrical supply. The project includes a supercharger that is connected to the carburetor which produces pressurized air for improved fuel combustion. Furthermore, the engine's compression can be lowered below that of detonation while still providing a surplus of power, decreasing heat losses in the water jacket. The engine is a single cylinder 4 stroke engine with a displacement of 159.7cc. For the first two gears, output parameters such as brake power, specific fuel consumption, brake thermal efficiency, and mechanical efficiency are measured. The loads are applied through manual loading using a rope brake with a maximum load capacity of 5 kg. Calculations are made on engine running with and without supercharger fitted to the carburetor. The mechanical efficiency of the engine is increased 5% and 3% in gear 1and 2 and input powerhas decreased 18 and 12 % respectively. Also, specific fuel consumption has decreased about 6and 4% for gears 1 and 2 and brake thermal efficiency has increased 6 and 2% respectively. Thus, the results gave no lag time, higher horse power and increased power in lower gears withthe supercharger. [ABSTRACT FROM AUTHOR]
