Investigation on the Effect of Ignition Timing on SI Engine

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
