Should You Turn Off the Engine When Parking for 10 Minutes?

It is more appropriate to turn off the engine when parking for more than 1.5 minutes, as this saves fuel. Additionally, if the vehicle remains idling for an extended period, the engine will continuously operate at low RPM, making it more prone to carbon buildup on the piston valves. Effects of prolonged idling on a car: 1. Prolonged idling increases the time it takes for the engine to reach normal operating temperature. When gasoline is sprayed onto the back of the valves, it evaporates more slowly, leading to carbon buildup. 2. Frequent idling reduces the airflow into the engine, weakening the cleaning effect on carbon deposits and promoting their accumulation. Prolonged idling refers to running the engine in neutral for extended periods, which can cause multiple issues such as poor heat dissipation, increased emissions, higher carbon buildup, and increased fuel consumption. 3. During engine idling, the lower temperature and pressure inside the cylinders prolong the ignition preparation time. Combined with reduced cylinder sealing, this can lead to engine knocking and shorten the engine's lifespan.
I often ponder how much impact parking and turning off the engine has on the environment, especially in cities. A car idling for 10 minutes releases significant pollutants like carbon dioxide and carbon monoxide, exacerbating air pollution and global warming. From what I understand, turning off the engine immediately reduces emissions, making it environmentally friendly. Modern car designs have optimized the starting system, so frequent engine shutdowns won't severely wear out the battery unless it's an older model. From an environmental perspective, I recommend turning off the engine if parked for more than 10 minutes—it saves money and contributes to the planet, and making it a habit can also enhance a sense of driving responsibility.
