Main reasons:
1. Check the spark plug. Do not use it for too long and the gap should not be too big. Replace it with a new one if necessary.
< p>2. High voltage wires must meet standards. High voltage and high temperature resistant wires and contact with the ignition coil plug must be properly matched.3. The coil ensures that there is no breakdown or current leakage.
The working principle of the ignition coil:
The reason why the coil ignition can convert the low voltage electricity of the car into The high voltage is that it has the same shape as an ordinary transformer, and the transformation ratio between the primary coil and the secondary coil is large. However, the working mode of the ignition coil is different from ordinary transformers. Ordinary transformers operate continuously, whileIgnition coils operate intermittently. They store and discharge energy repeatedly at different frequencies based on different engine speeds.
When the primary coil is turned on, a strong magnetic field is generated around it as the current increases, and the iron core stores the magnetic field energy; when the switching device disconnects the primary coil circuit, the magnetic field; of the primary coil In rapid decay, a very high voltage will be induced in the secondary coil. The faster the magnetic field of the primary coil disappears, the higher the current when the current is disconnected, and the higher the turns ratio of the two coils, the higher the voltage induced by the secondary coil.
1. First check whether the engine oil and gasoline are newly added. If they are not newly added and are more than three months old, you need to change the engine oil and gasoline and replace them with new ones. , because engine oil and gasoline have an expiration date. Only three months. Engine oil and gasoline used for more than three months have lost their viscosity and have no effect.
2. The old gasoline generator is having trouble turning on. We need to check the spark plug for carbon deposits. If so, it must be cleaned or replaced with a new one. Then check if the air filter is too dirty, causing a lack of air. If so, it also needs to be cleaned or replaced. We also need to check if the engine oil has melted, because if the machine is not used for a long time, the engine oil needs to be drained. Finally, we also need to check whether the gasoline is qualified and whether it has evaporated. , resulting in insufficient purity and difficulty in inflammation.
3. Check if the start methodrage is correct, check whether the oil switch can be turned on, whether the air door is closed when the cold engine is first started and whether the starting speed is reached, etc. First, turn on the crankcase oil drain switch, quickly fire the engine, and check the oil flow to determine the extent of the fault. If no oil comes out of the oil switch or little oil comes out, the mixture is not entering. the cylinder or the mixture is too thin. If there is a lot of oil leaking from the oil switch, the mixture is too rich. The reason may be that there is a problem with the oil supply system, or it may be that the starting method is incorrect and needs to be restarted.
4. Remove the high voltage wire from the spark plug and test for fire. If there is no spark or the spark is very weak, it means that the magneto or high voltage wireis defective. the spark is strong, it means the spark plug is defective or the cylinder is leaking and the mixture is poor. Confirm whether the spark plug can work normally, if not, it should be replaced in time.
5. It is difficult to start a gasoline generator. New machines require a certain break-in period. A qualified generator is not worn out, but damaged, so it is better to start the generator once a month. .-2 times.
