What are the causes of cylinder head gasket burning in automobiles?
1 Answers
Here are the specific causes of cylinder head gasket burning in automobiles: 1. The engine operates under heavy load for extended periods. This leads to detonation combustion, causing localized high temperature and high pressure in the cylinder, which burns the gasket. 2. When tightening the cylinder head bolts, the operation was not performed according to specified requirements. Uneven torque causes the gasket to not lie flat between the cylinder block and cylinder head joint surfaces, resulting in gas leakage. 3. Excessive ignition advance angle or fuel injection advance angle. This increases cycle pressure and temperature excessively. 4. Poor quality cylinder gasket with uneven thickness, air pockets in the sealing edges, uneven asbestos distribution, or loose wrapping edges. 5. Warped cylinder head, excessive unevenness of the cylinder block surface, or loose individual cylinder head bolts, leading to poor sealing.
