What effect does excessive heat have on reciprocating engines?

Excessive heat in reciprocating engines has a significant adverse effect on the life of engine parts. At elevated temperatures, the materials used in engine components can experience various forms of degradation, including thermal expansion, warping, and even melting of critical components. Lubrication becomes less effective at high temperatures, leading to increased friction and wear. This can result in accelerated breakdown of oil, leading to deposits and sludge, which further exacerbate wear and tear on the engine. In addition, high temperatures can strain metal components, leading to fatigue and eventual failure. Overall, maintaining optimal operating temperatures is crucial for ensuring the longevity and reliability of an engine.
