What Causes Engine Seizure?
2 Answers
The causes of engine seizure in automobiles include the following points: 1. The primary cause of engine seizure is still related to vehicle quality issues, specifically design defects that allow the engine temperature to exceed the maximum tolerable limit, resulting in engine seizure. 2. Insufficient or poor circulation of engine oil leads to inadequate lubrication, causing severe heat dissipation problems, which can also trigger engine seizure. 3. Overuse resulting in excessive engine workload can lead to phenomena known as engine seizure or cylinder compression. 4. Inaccurate adjustments in the engine's intake/exhaust system or ignition timing, causing timing errors, are another contributing factor to engine seizure.
I've seen engine blowouts quite a few times, mostly caused by internal overheating or insufficient lubrication. For example, when the cooling system fails—like coolant leakage or fan malfunction—it causes cylinder temperatures to skyrocket, leading to piston expansion that cracks the cylinder block. Another common cause is dirty or leaking engine oil, which increases friction and severely wears down the cylinder walls. Other typical reasons include prolonged high-speed driving without breaks, overloading the vehicle, or incorrect ignition timing causing detonation shock. For prevention, it’s crucial to regularly check coolant and oil conditions, monitor oil levels every few thousand kilometers, avoid aggressive driving in summer, and take breaks when needed. Otherwise, repairing a blown engine is costly and poses serious safety risks.
