Engine cylinder cushion oil leakage (summary of solutions to automobile engine cylinder cushion leakage) Engine cylinder pad is Binance downloadan important part connecting the cylinder head and cylinder block. Its main function is to prevent the mixing between lubricating oil, cooling water and fuel, and It can also maintain the balance of pressure. However, with the passage of the car's driving time, the engine cylinder pad will also wear and age, resulting in leakage of lubricating oil or cooling water, which in turn affects the performance and safety of the vehicle. This article will introduce in detail the cause, identification method and solution of engine cylinder cushion leakage. Reason 1. Natural old ageChemical: The engine cylinder pad has been used for too long and has experienced frequent high-temperature and high-pressure working conditions, resulting in the rubber material becoming hard and cracking, so that it cannot be effectively sealed. Two. Overcooling or overheating: The engine with too much cooling water or overheating will cause the cylinder pad to overexpand and produce pressure, resulting in cracks or loosening. 3. Head swing: Due to excessive vibration of the engine, the cylinder head is loose, and the cylinder pad is loose or moved. Four. Wrong installation: Wrong installation methods, such as over-tight cylinder bolts or nuts with insufficient locking strength, will also cause the cylinder gasket to be incompletely sealed. Identification method 1. Leakage: When the engine is running, oil leakage generally occurs between the cylinder block and the cylinder head, while cooling water leakage occurs on the front and rear of the engine. Two. Air pressure test: a method to detect whether the cylinder gasket is leaking by applying pressure to the cylinder head or adding air pressure to the cylinder block.3. Water vapor detection: by adding dye to the engine intake pipe, and then observing whether the rear row discharges blue smoke. If there is, it means that the cylinder pad is leaking. Solution 1. Replace the cylinder pad: For seriously damaged engine cylinder pads, a new cylinder pad needs to be replaced to ensure tightness. Two. Bolt inspection and adjustment: For cylinder cushion leakage caused by improper installation, it is necessary to check and adjust the tightness of the bolt to ensure that the torque of each bolt is appropriate. 3. Precisely check the cylinder head, cylinder gasket and body surface to ensure that the surface roughness meets the requirements in order to establish a good seal. Four. Fill the cylinder gasket with high-temperature sealant: Apply high-temperature sealant evenly on the surface of the cylinder gasket to improve the tightness. 5. Clean the water tank and water pipe: remove the scale in the water tank and water pipe in time to reduce the temperature of the cooling water and the risk of leakage.6. Replacement accessories: While replacing the engine cylinder pad, it is best to replace the peripheral accessories, such as cylinder head bolts, gaskets and cylinder cover seals, to ensure that the replaced engine can give full play to its performance for a longer time. Conclusion The leakage of the engine cylinder pad will have an adverse impact on the safety and performance of the car. By identifying and selecting the right solution in time, losses can be reduced and the service life of the car can be improved. It should be noted that if the engine cylinder cushion leaks, it must be dealt with in time to ensure the safety and stability of the car, and at the same time better protect the life and property safety of drivers and passengers.
