The specific steps for replacing the portable generator spark plug are as follows:
Tools needed: screwdriver, socket.
1. When disconnecting the high voltage wire connector, be gentle. Do not shake the spark plug insulator forcefully during operation, as this may easily damage the sealing performance of the spark plug.
2. The motor can be disassembled after cooling. After loosening the spark plug, use a thin hose to blow out the dirt around the spark plug to prevent dirt from falling into the combustion chamber after unscrewing the plug.
3. The area around the screws, spark plug electrodes and gaskets must be kept clean, dry and free of oil, otherwise it will cause electrical leaks, air leaks, weakening of sparks and d other defects.
4. When installing, useUse a sleeve to align the spark plug with the screw hole, and gently screw it in by hand. After tightening it to about half the total thread length, tighten. the lever with additional force. If the hand is not smooth when twisting, go out and check whether the threads are aligned or whether there are any impurities trapped in the threads. Do not tighten blindly to avoid damaging the screw hole and damaging the cylinder head.
5. Tighten to the required torque. If it is too loose, it will cause air leakage. If it is too tight, the gasket will lose its elasticity, causing air to leak.
The piston of a gasoline generator hits the spark plug
The basic principles and structures are the same, but the designs are not necessarily the same. There are many types of generators and motorcycles. , and they are used Spark plug models and sizes are also different, some are universal and others are not interchangeable, and there are two- and four-stroke gasoline generators. Today's motorcycles are primarily four-stroke, depending on the specific model. , it is best to compare it with an old spark plug.
No. The highest point of the piston stroke is a horizontal plane above the cylinder. There is a distance between the piston and the spark plug and they will not touch each other. A gasoline generator is generally composed of a stator, rotor, end cover, bearing and other components. An engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually a work cycle process.
