Should the Engine Be Turned Off When Parking for Ten Minutes?

It is recommended to turn off the engine when parking for ten minutes. Generally, if the parking time is less than five minutes, you may choose not to turn off the engine; however, for durations exceeding five minutes, it is advisable to shut it down. The hazards of prolonged idling include: 1. Impact on engine performance: When a vehicle remains idling for an extended period, the engine operates continuously at low RPM, which can lead to increased carbon deposits on pistons and valves. This may result in unstable idling and other adverse effects on engine performance, potentially shortening the engine's lifespan. 2. Incomplete fuel combustion: At very low engine speeds, the intake vortex weakens, leading to poor fuel atomization and incomplete combustion. Additionally, low engine speeds increase leakage through valves and piston rings.

What is the recommended tire pressure for sedans in winter?

The recommended tire pressure for sedans in winter is between 2.4 to 2.5 bar. Vehicle tire pressure varies depending on different conditions: 1. Seasonal factors: In winter, it is advisable to increase the standard tire pressure by 0.2 bar, while in summer, the standard tire pressure should be reduced by 0.1 bar; 2. Tire condition: For new tires, the pressure should be increased by 0.2 bar compared to the standard tire pressure. Hazards of abnormal tire pressure: 1. Excessive tire pressure increases the risk of a blowout, causing the middle part of the tire to bulge and contact the ground, significantly reducing the vehicle's grip on the road and failing to provide sufficient friction during emergency braking; 2. Insufficient tire pressure causes the outer edges of the tire to contact the ground, preventing the entire tread from making contact, increasing wear on the sidewalls while failing to provide adequate grip area. Frequent wear on the thinnest part of the sidewalls can directly lead to premature tire failure.
