Does Engine Idling Damage the Car?
1 Answers
Engine idling in place can be very harmful to the car. Problems that may arise from engine idling include: 1. Ineffective complete vaporization of gasoline: The normal operating temperature of an engine is approximately between 90 to 110 degrees Celsius. Before reaching the operating temperature, the fuel system's low temperature prevents effective complete vaporization of gasoline, making it difficult to ignite and start the engine under such conditions. 2. Gear oil flows to the lower part of the transmission: The lubrication of the transmission gears is something most people don't understand and often overlook. The similarity between transmission gear oil and engine oil is that, when the car is cold, the gear oil flows to the lower part of the transmission. 3. Difficulty in shifting when the car is cold: Only when the car is in motion does the operation of the gears bring up the gear oil from the bottom to lubricate the upper part. This is why most cars experience difficulty in shifting when cold. 4. Only the engine moves during idling: Since the transmission does not have a gear oil pump, only the engine moves during idling, while the rest of the parts remain stationary. This situation only improves after actually driving on the road and slowly moving for a period of time. 5. Engine damage: Idling to warm up the car is unnecessary because the effect is limited, and it wastes gasoline and time. Moreover, when the engine idles, gasoline may not burn completely, leading to carbon buildup, which further damages the engine.
