What is the high temperature of an engine?
2 Answers
Engine high temperature is 110 degrees Celsius. Consequences of engine overheating: If the engine temperature is too high, it will cause the lubricating oil to exceed normal values, reduce the viscosity of the lubricating oil, lower the oil pressure, and prevent the oil from reaching the moving parts for lubrication, resulting in thinner oil films. The antioxidants in the lubricating oil function effectively only below 160 degrees Celsius. Excessive temperature will accelerate the oxidation of the lubricating oil. High combustion chamber temperatures can also lead to incomplete combustion, causing carbon deposits or knocking. The danger of engine knocking is that the generated impact force obstructs the upward movement of the piston, damages the cylinder wall surface, and leads to unstable operation and damage to components. Solutions for engine overheating: Clean the carbon deposits in the engine. Carbon deposits in the combustion chamber can affect the heat dissipation of the cylinder and cylinder head, causing the working temperature of the air-fuel mixture to be too high. The cylinder head can be removed for cleaning. For a thorough cleaning of carbon deposits, the piston, crankshaft, and other parts can be disassembled and cleaned. Check the coolant level, radiator, hoses, and other components for leaks.
Speaking of engine overheating, after driving for so many years, I've learned that temperature isn't just an absolute number. It's safe when the coolant temperature gauge reads between 95 to 105 degrees during normal operation. But once it jumps to 110 degrees or higher and the warning light comes on, that's a real danger signal. I remember one summer when stuck in traffic, my car's temperature soared to 112 degrees, and white smoke started coming from the engine. Luckily, I pulled over in time and found out the radiator was clogged. Prolonged exposure to such high temperatures can cause piston deformation, make engine oil thick and ineffective, and significantly reduce engine lifespan. My advice is to keep an eye on the temperature gauge while driving—anything above 105 degrees warrants caution. Prevention is always easier than repairs. Regular maintenance of the cooling system, like flushing the radiator and replacing coolant, can effectively prevent overheating issues.
