This study has been undertaken to investigate and analyze the effect of sparkplug flame if we increase the electrode gap in single cylinder 125CC vertical engine. The performance of automobile engines is impacted by a variety of factors. One of the world's primary sources of fuel consumption today is the gasoline spark ignition mechanism in automobiles. The spark plug is one of the crucial parts of a petrol engine during the combustion process. An engine's performance declines when it isn't running consistently, but it also increases fuel consumption, vibration and HC emissions. There are numerous causes of pollution. The improper gap of electrode in the sparkplug is one of the causes. Spark plugs play a critical role in the combustion process in a gasoline engine. The combustion engine's backfire and banging are brought on by an incompatibility between the fuel utilized and the width of the spark plug gap. Consequently, the spark plug gap was investigated with an emphasis on managing the combustion process to enhance engine performance. The parameters of spark plug gap when the gap increased have been explored in this study. The standard gap of 125CC single cylinder engine is 0.7mm. In experiments, it has been found that the vibration and noise increase correspondingly as the spark plug gap increase; on the other hand, the exhaust emission (HC) value increases.
