Does Keeping the Engine Running All the Time Damage the Car?

Car can run continuously for 24 hours, which causes normal wear to the engine. Here is relevant information about the engine: 1. Introduction: An engine is a machine that can convert non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines, external combustion engines, jet engines, electric motors, etc. An external combustion engine converts the heat energy generated by combustion into kinetic energy, and the steam engine improved by Watt is a typical external combustion engine; an internal combustion engine is a reciprocating piston engine, and the biggest difference between this type of engine and an external combustion engine is that the fuel burns inside it; a jet engine refers to an engine that directly generates reactive thrust by the high-speed airflow ejected from the nozzle.

As a car enthusiast, I've always paid attention to engine maintenance. Continuous engine operation does cause harm. Prolonged idling increases component wear, especially on pistons and cylinder walls, due to insufficient oil lubrication. Fuel consumption surges dramatically, wasting gasoline unnecessarily. Modern car engines are designed for driving - they have poor thermal management during idling, which easily leads to carbon buildup, affecting exhaust system and spark plug performance. While summer idling may cause overheating, winter idling might help with warm-up. It's recommended to avoid idling for more than a few minutes, and regular driving ensures smooth operation. When changing engine oil, I make sure to check for signs of buildup.

Having driven trucks for many years, I deeply understand the drawbacks of keeping the engine running continuously. It accelerates wear and tear and unnecessarily consumes fuel. When idling, the vehicle doesn't move, the engine speed becomes unstable, and carbon deposits form quickly, making future cleaning troublesome. Idling immediately after a cold start is particularly harmful, as insufficient engine warmth prevents lubricating oil from adequately covering critical components. To save fuel and reduce maintenance, it's better to turn off the engine during short waits. I've checked the battery condition, and charging it while driving is more effective. Developing the habit of turning off the engine during long red lights protects your beloved vehicle.

I am a practical car user. Keeping the engine running for extended periods can harm the vehicle. Idling wastes fuel, increases pollution emissions, and causes long-term damage to engine health. Incomplete oil circulation leads to localized wear and may cause carbon buildup that clogs exhaust components. It's recommended to limit idling to necessary short durations like warming up the engine, and turn off the engine in other situations to conserve resources and extend vehicle lifespan.
