What is complete combustion effect on engine performance?
well you see when the gasoline enters the engine the piston compresses it and then the spark ignites it when it doesn’t burn all the commbustable gases in the combustion chamber it goes out the exhaust. so in other words you didn’t get all the power out of the gas that went in. since the combustion of the gasoline in the combustion chamber is the engines source of power if the gasoline doesn’t completly combust the engine loses power from that. This is why when a vehicle is not firing on one cylinder or more you have a great loss in power. So by making sure your engine combusts the fuel properly you can get a increase in power and performance.
