Abstract:
The primary objective of the project was to investigate on effects of ignition timing of SI
engine. In this project, the experiment method with apparatus setup was used to
determine the engine performance of engine torque, brake power, brake specific fuel
consumption, brake thermal efficiency and brake mean effective pressure for Modenas
Kriss 120cc engine. A different magneto angle will be tested to get a good
performances. During the experiment, the engine was coupled to a 20kW generator
dynamometer to measure several engine performance parameters at various engine
speeds with maximum engine load. All the measurements data in the experiment were
measured and transformed into the performance curve to determine the best result of
engine performance
