One, prevent the mixed gas from being too thick
The summer temperature is high, gasoline is easy to flow, and at the same time, the heat hole expands, which increases the flow of gasoline, and the gasoline is easy to evaporate, causing the mixture to be too rich. Therefore, the heat hole should be adjusted, the position of the accelerator and the throttle rocker arm should be adjusted, and the oil level should be appropriately lowered to reduce the fuel supply.
Two, anti-gas resistance
The fuel system of gasoline engines in summer is prone to vapor lock due to temperature rise, resulting in insufficient fuel supply or even interruption of fuel supply in the oil circuit. To prevent air resistance, use asbestos pads to separate the gasoline pump from the exhaust pipe, or wrap the gasoline pump with a damp cloth to cool down.
Under high temperature, the evaporation of oil and water will increase. The fuel tank cover should be tightly closed and the fuel pipe should be prevented from oil leakage; the water level of the water tank, the oil level and height of the crankcase, and the brake fluid in the brake master cylinder should be checked frequently. The height of the liquid level and the height of the electrolyte level in the battery, etc. In case of non-compliance, add and adjust in time.
Four, prevent overheating
In order to prevent the engine from overheating, the fan belt should not be stained with oil during maintenance to prevent slipping, and the belt should be kept tight. During long-distance driving, pay attention to rest in good time. When resting, try to choose a cool place and open the engine hood to ventilate and dissipate heat. When the tire pressure increases due to heat, you should stop and cool down immediately, otherwise there is a risk of a tire blowout. Pay special attention not to use deflation or pour cold water to lower the tire pressure and temperature.
5. Prevent spontaneous combustion and explosion
When the temperature is high, the heat dissipation is slow. The temperature of the car water tank often affects the normal power output of the engine because of the high temperature, and may even cause the engine to fail to work normally.
High temperature also causes some parts to expand and deform. The lighter ones will accelerate the wear of the parts, and the heavy ones will burn the parts. At the same time, long-term use of on-board electrical appliances and air-conditioning systems will also cause the car’s circuit system to overheat. If various wires or resistance boxes are not maintained at ordinary times, severe overheating may even cause the car to spontaneously ignite.
Six, prevent poor lubrication
The lubricating oil is easy to be thinned by heat, has poor oxidation resistance, is easy to deteriorate, and even causes failures such as bush burning. Therefore, the crankcase and gearbox should be replaced with summer lubricating oil, and the quantity and quality of the lubricating oil should be checked frequently and replaced in time.
Seven, regularly clean the car air conditioner
The car air conditioner will have an unpleasant sour smell after being used for a long time. The water vapor adheres to the air conditioner evaporator and produces a variety of molds harmful to human health. Therefore, it is very important to clean the car air conditioner regularly to eliminate mold and to create a fresh interior space.
8. Pay attention to sun protection and UV protection
When parking, you should park your car in a cool place as much as possible, cover it with a silver car jacket, or wax and coat the car body, stick an explosion-proof film on the car windows, and place a sun block and light-proof pad in the car to block the sun.
