What Causes an Engine to Blow Up?

[Yvette]

The reasons for an automobile engine blowing up are: 1. Design defects causing the engine temperature to exceed its tolerance limit; 2. Poor-quality engine oil and operational malfunctions leading to severe cooling issues; 3. Overuse resulting in excessive workload on the engine; 4. Inaccurate intake/exhaust system and ignition timing in the engine. Precautions to prevent engine blow-up include: 1. Applying glaze to the paint surface to prevent direct exposure; 2. Parking the vehicle in shaded areas to avoid prolonged sun exposure and opening the engine hood for ventilation and cooling. An engine blow-up occurs when the tachometer enters the red zone, where excessive heat causes piston expansion and seizure within the cylinder, leading to engine failure. In severe cases, excessive pressure with immobile pistons may lock all four wheels and result in intense flame ejection.
