Engine Cylinder Holding Prevention and Elimination Techniques
Engine cylinder holding is one of the most common engine failures, which can not only easily cause serious engine damage, but also bring safety hazards. Therefore, it is very important to understand the occurrence conditions and preventive measures of engine cylinder holding, improve maintenance technology, and deepen the level of automobile maintenance.
The causes of cylinder holding in engines can generally be divided into the following types:
1. Poor maintenance. The main cause of engine cylinder holding is poor maintenance. The fuel system of the car is aging and the use of poor quality oil and poor quality gasoline, especially the lack of maintenance in the periodic 800 kilometers, and the carburetor setting is unreasonable, etc., all have a greater impact on the fuel system wear and cause cylinder holding.
2. Intake and exhaust systems. The sudden increase of intake pressure, or the occurrence of intake pipe resistance, can cause cylinder holding; if the exhaust failure occurs, it can also cause cylinder holding.
3. Other factors. Long-term continuous operation of the engine, failure of car tune-up and ignition, or the presence of spark plug deviation, can all affect the operation of the engine and cause cylinder holding.
The following measures can be taken to prevent the engine from cylinder holding:
1. Get rid of bad habits in driving. Do not always use the car at high speeds, nor should it be used for long-term continuous running, which may easily lead to the aging of the fuel system and the occurrence of cylinder holding.
2. Regular maintenance. For cars with different mileage, they should do a care maintenance once every 800 kilometers, and do a major maintenance once every 8 thousand kilometers. During the maintenance process, the roadside maintenance shop may use special vehicles to transport the car to the engine overhaul maintenance workplace to check the spark plug, intake and exhaust pipes, spark plug cable, fuel pump, air filter and other parts.
3. Replace the oil and filter in time. Replace the engine oil and filter in time, and refine the quality oil as much as possible. Generally, the oil used should meet the requirements of API or CCMC oil quality, and engine oil with higher viscosity can be used in winter.
4. Clean the carburetor. The spare parts of the carburetor need to be cleaned in time. It is necessary to regularly clean the carburetor to maintain the performance of the carburetor and avoid blockage, so as to deal with the fuel supply and pressure problems.
If the engine holds the cylinder, it should be timely removed and replaced. If the engine is still overheated after the fault is removed, it means that the cylinder body has failed and should be repaired. The main method used to repair cylinder failure is plate welding, anti-seize compound or welding of powder metallurgical steel. After the repair is completed, the engine should undergo a test after assembly and commissioning to ensure that the repair is successful.
In short, engine cylinder holding is a common engine failure. Therefore, regular maintenance and removal of bad habits in driving can reduce the occurrence of cylinder holding. If the engine holds the cylinder, timely removal and replacement are needed. If the fault cant be removed, we need to do cylinder repair work. The above are the prevention and elimination techniques of engine cylinder holding.
