Air pollutant to environment is the major issue due to gas emission from industries and vehicles. The source from the vehicle are misfire condition and worse knocking condition will affect the engine. It cause by several components failure such as clogged spark plugs and high voltage cables, insufficient intake mixture, and others. A study is presented of the influence of using a microcontroller to actuate artificial engine misfire and knocking condition on a spark ignition engine. Single cylinder engine is use in the study. The paper focuses on detection of engine misfire and knocking (EMK) by actuating the artificial condition of EMK. Microcontroller is design to initiate spark plug ignition timing by several times, so the signals can be identifies for the fault detection. A switch will be controlling the artificial misfire and knocking condition. Therefore the switch for artificial EMK condition is located with the same controller. The accelerometer mounted on the engine signal and it will record during the artificial EMK condition is activated for analysis.
