No, spark plug problems and ignition circuit problems will cause this.
1. Spark plug problem: The spark plug may have high pressure and misfire for reasons such as excessive life or dirt.
2. Ignition line problem: Ignition line failure or poor contact will cause high voltage failure and the line must be inspected and repaired.
The motorcycle cannot produce electricity and has no fire. The igniter and high voltage box are not broken.
1. in the high voltage pack and the vehicle cannot start.
2. Once the high voltage package loses electricity, the vehicle will feel frustrated while driving, sometimes going faster and sometimes slower. If the leak is serious, cyclists in the car will feel like they are being electrocuted.
3. Once the current ofbreakdown of the high voltage assembly becomes weak, it will cause insufficient combustion, weaken the vehicle and increase fuel consumption.
The main function of the motorcycle high voltage assembly is to generate high voltage electricity to ignite the combustible gas mixture in the cylinder through the spark plug. To put it simply, it is a miniature transformer that converts low voltage to high voltage. When the motor is running at high speed, its voltage can reach around 20,000 volts.
The motorcycle's high voltage assembly is a step-up transformer that increases the 6V or 12V voltage generated by the motorcycle's generator to 12,000V and sends it to the spark plug for ignition. Today's high voltage packages are all closed. If they are broken, you can only replace them with new ones. To check the quality of the high voltage package, simply remove the spark pluglight, connect it to the spark plug sleeve and turn it. 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 fire. The sparks are blue and the crackling sound is clear and powerful. , indicating that the high voltage box is intact and there is no spark. This means that the high voltage box has been burned and the sparks produced are dark red, indicating that the coil inside the high voltage box is short circuited. 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. , it powers the igniter.
Indetailed training:
2. When the oil circuit is normal, if the high pressure assembly is damaged, it will naturally be unable to provide high pressure power for ignition of the spark plugs.
3. If it is not completely damaged, such as poor conduction or leakage, it will also cause abnormal ignition, intermittent or stopped ignition, resulting in poor acceleration, poor starting or poor driving. statuses such as extinction.
When some malfunction phenomena such as the above occur, it can be judged from two aspects, one is the oil circuitand the other is the ignition circuit. When the oil circuit is normal, you just need to do this. Check the high voltage assembly and ignition circuit, spark plugs and other related parts or parts.
Baidu Encyclopedia - High Voltage Package
Motorcycles do not have high voltage electricity. In addition to the ignition and high voltage package, the magneto stator coil, electric door lock switch and power off switch (it's the big red button on the right handlebar switch, but not all cars have do not have an off switch), and if there is a problem with the wiring between them, there will be no high-voltage electricity. If it is determined that the igniter and high voltage assembly are not damaged, use a multimeter to measure whether the magneto stator coil (including the ignition coil and trigger coil) is normal, measure whether wiring of the ignition systemis normal and check if the ignition kill wire (for AC ignition vehicles) is normal. If there is a short, check to see if there is power to the ignition power cord. If it is a car with an electronic induction tachometer, also check if the power cord of. the tachometer is short circuited.
