Boyuan gasoline generator failure:
?1. The gasoline engine cannot start or is difficult to start
(1) Failure phenomenon
① Pull the starting rope This is normal, but the gasoline engine won't start and has no response.
② Black smoke comes from the exhaust, but the gasoline engine cannot start.
③The carburetor continues to leak oil.
④Unable to start, unscrew the spark plug, the electrode is damp and gives off a strong smell of gasoline.
⑤ When you pull the starting device or start it electrically, you will feel that the gasoline engine continues to run easily. Once the compression is complete, you will still feel little resistance.
⑥The gasoline engine has no back pressure and is not easy to ignite and start, but there is an explosion phenomenon in the exhaust pipe.
⑦ When starting the gasoline engine, there ishas a reverse rotation; There is a backfire when the carburetor starts.
(2) Cause of failure
① The ignition switch is shorted to ground (electric start model).
②The spark plug is damaged; the spark plug electrode gap does not meet standard requirements, the spark plug is dirty, damp and poorly insulated.
③The high voltage wire falls or is poorly insulated, causing leakage; the igniter is defective or damaged by a fault.
④ There is no fuel in the fuel tank; the oil switch is not on; Fuel tank cap breather hole is blocked.
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 wire should be purchased with high voltage and high temperature resistance confelm to standards, and the contact with the ignition coil plug must be correctly matched.
2. p>3. Make sure that the ignition coil has no breakdown or current leakage.
Working principle of the ignition coil:
The reason why the coil ignition can convert low voltage electricity into The car switches to high voltage because it has the same shape as an ordinary transformer and the transformation ratio between the primary coil and secondary coil is large. However, the working mode of the ignition coil is different from ordinary transformers. Ordinary transformers operate continuously, while ignition coils operate intermittently. They store and discharge energy repeatedly at different frequencies depending on different engine speeds.
When the primary coil is turned on, a strong magnetic field isgenerated 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 larger the turns ratio of the two coils, the higher the voltage induced by the secondary coil.
