How to properly maintain the spark plug of gasoline generator

If the gasoline generator is the heart of the device, then the spark plug is the heart's pacemaker. Every burning of gasoline in the generator is ignited by a spark plug. The performance of the spark plug (spark) directly affects the performance of the engine.

The spark plug works in the combustion chamber of the generator and is in a harsh environment of high temperature and high pressure for a long time, and is a vulnerable component. Regular inspection, maintenance and replacement of Spark Plugs is especially important.

Common problems and treatment methods of spark plugs

1. Carbon deposit

The main cause of this phenomenon is that the combustible mixture is too rich and the fuel cannot be fully burned, and a large amount of deposits are formed in the skirt of the insulator, resulting in carbon deposits. It is normal for the spark plug to produce carbon deposit during use, but if it is not cleaned for a long time, it will accumulate more and more. Zui will eventually lead to leakage or even ignition, so it should be cleaned regularly.

When cleaning, the spark plug can be soaked in gasoline first, then scraped off with a brush to dry. In order to avoid the occurrence of carbon deposits, the air filter should be kept clean, the overload operation should be avoided, and the fuel should maintain a certain degree of purity.

2, the flooding tank

The reason why the spark plug is flooded is mostly because the starting method is wrong or the engine failure causes the user to fail to start the engine multiple times in succession. Because each time the engine is pulled (or electrically started), the carburetor will continuously inject the spark plug. After many starts of the test, the gasoline sprayed on the spark plug electrode will be more and more, and an oil film will be formed, which will cause the spark plug to not generate sparks, that is, the flooding phenomenon.

After the flooding occurs, remove the spark plug using the sleeve, wipe the gasoline on the spark plug with a clean cloth, then replace the spark plug and try to restart the engine.

3, spark plug ablation

The spark plug electrode is rounded and the insulator is connected, indicating that the gasoline quality is poor or the spark plug heat value is too high; the electrode is melted and the insulator is white, indicating that the temperature in the combustion chamber is too high, and the spark plug should be replaced at this time.

Spark plug use maintenance taboo

1, avoid long-term use

If the spark plug is used beyond the economic life, it will not be conducive to the engine's power and economy, and should be replaced in time. Replace the spark plug one or two times at a time.

2, avoid fire and knife scraping

In reality, some people often use fire to remove the carbon deposits and oil on the spark plug electrodes and skirts, which is very harmful. Because the temperature is difficult to control when the fire is burned, it is easy to burn the skirt insulator, causing the spark plug to leak. Also, electrode damage can result if a knife, sandpaper or metal scrape is used. The correct treatment method is to soak the spark plug in alcohol or gasoline, and then dry it with a brush after the carbon is softened.
