The size of the spark plug gap will impact the high voltage housing and ignition advance angle. A large spark plug gap will cause a relative increase in the voltage of the high voltage box and a relative delay in ignition.
The spark plug is installed on the side or top of the engine. The first spark plug was connected to the distributor by a cylinder wire. Over the past ten years, car engines were essentially connected. modified so that the ignition coil is directly connected to the spark plug. The working voltage of the spark plug is at least 10,000 V. High voltage electricity is generated by the ignition coil from 12 V electricity and then transmitted to the spark plug.
The main types are: quasi type spark plugs, protruding rim spark plugs, rim type spark plugselectrode, seat type spark plugs, pole type spark plugs, surface spark plugs, etc.
Detailed information
When the high voltage box is used, the primary coil is charged first, and a voltage of 200 ~ 300 V is self-induced in the primary coil; then it is loaded with the secondary coil. The mutual inductance of the secondary coils generates high voltage electricity of 18 to 20 kV. The voltage generated depends on the turns ratio of the two coils; voltage electricity is supplied to the spark plug for ignition. ?
The motorcycle's high voltage assembly is a step-up transformer, which increases the 6 V or 12 V voltage generated by the motorcycle's generator to 12,000 V and sends it to the spark plug ignition for ignition. Today's high voltage packages are all closed. If they are broken, you can only replace them with new ones and check the quality of the phigh voltage ackages.
Simply remove the spark plug and connect it to the spark plug sleeve, turn on the ignition key, press the outer end of the spark plug against the engine, press the motorcycle start lever with your foot and watch the spark plug ignite. Sparks will appear. Blue, the crackling sound is clear and loud, indicating that the high voltage box is intact.
If there is no spark, the high voltage box has been burned. If the sparks are dark red, it means the coil inside the high voltage box is shorted and should be. discarded.
The working principle of the high voltage box is to convert direct current to alternating current through an oscillator, increase the voltage through a step-up circuit, and rectify it to high voltage direct current when the voltage reaches a certain value. , he feedsyou the lighter.
