How Long Can a Car Engine Run Continuously?
2 Answers
Several thousand hours. During endurance testing, it can run continuously for several thousand hours. Introduction to Car Engines: It is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), electric motors, etc. The term engine can refer to both the power generation device and the entire machine including the power unit (e.g., gasoline engine, aircraft engine). Classification of Car Engines: Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others.
As an auto repair enthusiast who frequently deals with car issues, I believe the continuous operation time of a small car's engine is quite flexible, primarily depending on design quality and maintenance condition. Modern small car engines can typically run smoothly for about 10 to 12 hours during high-speed cruising. Theoretically, in extreme tests, they can operate non-stop for thousands of kilometers, but in actual driving, cooling system efficiency must be considered—poor coolant circulation can lead to component deformation or oil oxidation due to high temperatures. I recall a case where a driver continuously drove for 8 hours without a break, causing the engine to smoke and nearly burn out, making repairs quite troublesome. For daily use, it's advisable to stop and check the engine temperature and oil level every 2 hours during long trips, while ensuring the air conditioning and electronic systems do not add extra load. Regular oil changes and keeping the radiator clean are key to extending the engine's working life. From a safety perspective, considering human fatigue limits, taking breaks is not only necessary for the engine but also crucial for the driver's self-protection.
