Where is the spark plug located on a motorcycle?
1 Answers
The spark plug is located on the right side of the motorcycle's engine cylinder head. The replacement method is as follows: 1. Remove the engine cover and unscrew the fixing screw of the high-voltage wire terminal; 2. Remove the high-voltage wire terminal, loosen the spark plug, insert the hose on the high-voltage wire terminal into the combustion chamber, and pull out the spark plug; 3. Align the new spark plug with the screw hole and tighten it with a tool. The working principle of the spark plug is: the arc generated by the voltage between the electrodes ignites the mixed gas in the cylinder, maintaining the normal operation of the engine. The function of the spark plug is: to discharge the pulse high voltage sent by the high-voltage wire, break down the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder.
