Turn off the air conditioning before turning off the car. If you turn off the car first and then turn on the air conditioning, the engine will start with the load of the air conditioning the next time the vehicle is started, which can damage the engine due to the high load. Additional information: 1. Principle of car air conditioning: The working principle of car air conditioning involves the refrigeration system, which consists of components such as the compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower. These parts are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a closed system. 2. The compression process of car air conditioning: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator and compresses it into a high-temperature and high-pressure gas, which is then discharged from the compressor.

Is a tire pressure of 280 too high in summer?

Summer tire pressure of 280 is slightly high, and it can be appropriately reduced. Here is relevant information: 1. Tire pressure range: Cold tire pressure of 2.3, 2.4, or 2.5 bar is normal; after driving for a while, 2.5 or 2.6 is considered normal, but it should not exceed 2.8 bar as high tire pressure. 2. Impact of tire pressure: Higher tire pressure reduces the contact area between the tire and the ground, leading to poor grip, longer braking distance, noticeable bumpiness, and reduced comfort. However, it also results in lower resistance and relatively better fuel efficiency. Slightly lower tire pressure increases the contact area with the ground, improving grip and comfort, but it also increases resistance and fuel consumption. Naturally, tire pressure tends to be higher in summer.
