Can a Private Car Run Continuously for 24 Hours?

[Diane]

A private car should not run continuously for 24 hours. The reasons are as follows: 1. Cooling System: If the vehicle runs continuously for a whole day, it may experience cooling system issues, such as radiator blockage or water channel blockage, leading to overheating. In severe cases, it may even cause cylinder scoring due to the increased temperature. 2. Engine Oil Leakage: For some vehicles in poor condition, engine oil leakage may occur. The leaked oil will continue to heat up as the vehicle keeps running, potentially leading to spontaneous combustion. 3. Impact on Engine Output: After several hours of continuous driving, the vehicle's exhaust system may overheat. The overheated exhaust can trigger the Electronic Control Unit (ECU) to activate the vehicle's overheating protection, which will affect the engine's output.
