◆ Explosion-proof tires are prone to puncture when vehicles encounter hard objects at high speeds. Therefore, check the tire pressure at any time while driving. If you find that the tire is overheated or the pressure is too high, you should park the car in a cool place to cool down. Do not splash with cold water or deflate, otherwise it will cause a tire burst on the way and early tires. damage.
◆Anti-air lock Sometimes the engine is difficult to start after stopping for a few minutes, causing the oil supply to be interrupted.
Once air lock occurs, the driver should stop immediately to cool down and eliminate the fault.If your car is hydraulically braked and driving at high speed under high temperature, the brake fluid is prone to air "vapor lock", which makesBrakeSudden failure caused an accident.
◆Prevent driving in high temperature weather due to lack of water,Water tankThe evaporation of the water inside is accelerated, so always pay attention to check the cooling water quantity and pay attention to the water temperature gauge.Stop immediately when you find water shortage, but do not add water immediately, but wait for the idling operation to cool down before adding water, and be careful not to open it immediatelyheat sinkCover to prevent burns.
How to prevent "heatstroke" in cars
Under the scorching sun, a car generates a lot of heat during driving, which makes the ambient temperature of the vehicle work much higher than in other seasons. In order to ensure that the vehicle can work stably, it is necessary to do a good job in preventing heatstroke.

◆Check the air conditionerCar Air ConditionerIt is the most frequently used component in summer. First, check whether the air conditioner is lacking in fluorine; second, check whether there is leakage. Generally, there are observation holes on the drying tank, which can be judged from the flow of bubbles.
◆Choose the right onelubricating oilCheck the lubricating oil in each assembly of the engine and the chassis, and add high-viscosity lubricating oil and high-boiling grease. In addition, a brake fluid with a high boiling point (not lower than 115~120℃) should be used.
◆The speed should not be too fast. In order to prevent the tire from bursting, the tire should be inflated according to the specified tire pressure, and the vehicle speed should be appropriately reduced when the midday is extremely hot.
◆Adjust the on-board power supply to reduce appropriatelyAccumulatorElectrolyte density; appropriately reduce the charging current and voltage, and clean the regulator contacts.
