4hw.com.cn: the weather is hot, the temperature continues to rise, people can't bear the heat, the car will also be affected by the high temperature, so what should be paid attention to when refueling your car in summer to avoid trouble to the greatest extent?
Don't overfill
Don't top up in summer. If the gasoline is too full, the temperature will be high in summer, and the car itself will generate heat. The gasoline will expand and contract with heat, and the car engine will shake constantly. The gasoline will volatilize quickly in the form of gas or even liquid. Moreover, the time is long. Gasoline will also deteriorate, leaving a hidden danger to its own safety.
The tank cannot be empty for too long
When driving the vehicle, also pay attention to check whether the fuel gauge has reached the end at any time. When the pointer shows the remaining quarter of the fuel, you should be able to refuel. It is better to refuel when the oil meter light is on. If the oil tank is too empty for a long time and the temperature difference between inside and outside is large, the water in the oil tank is easy to be generated, which may corrode the oil tank, affect the oil quality and increase the load of the engine.
Don't choose to refuel at noon
The volume of gasoline will increase with the increase of temperature due to the expansion and contraction of heat. When the temperature decreases, the volume of gasoline will decrease. Gas is charged by volume. In order to save money, try to avoid it.
It's best to refuel in the morning or at night
The best time to go to the gas station is at night or in the early morning. On the one hand, it can avoid being attacked by the sun poison and high temperature at noon. On the other hand, it is because the gasoline is charged by volume rather than by weight, with heat expansion and cold contraction. The volume of gasoline at night or in the early morning is relatively small. The same volume of gasoline can have better quality, and it is not easy to bubble and volatilize. Therefore, refueling at night or in the early morning can save a lot of money.
Don't refuel in typhoon and rainstorm
Because summer is a thunderstorm and typhoon season, the air will be filled with a large number of charged particles in the air after lightning stroke. When the vehicle is refueled in thunder, the oil gun is very easy to introduce the stray current into the fuel tank, causing a fire. Moreover, the rainstorm will cause the rainwater to flow into the oil tank, which will cause potential safety hazards.
Come on, remember two numbers
When the fuel is 25% of the tank, it's time to refuel. If the fuel is only added when the fuel tank is near the bottom, the impurities accumulated at the bottom of the fuel tank will be easily pumped into the fuel system, which will cause the fuel supply not to be smooth, and the air is easy to be stored. When the temperature difference between day and night is large, water vapor will be formed and mixed in the oil, resulting in poor combustion.
But refueling is not the more full the better, 80% is the best amount of refueling. Many motor vehicle drivers will fill up the fuel tank when refueling, which will not only increase fuel consumption, but also easily cause body failure. Usually, when driving a short distance in the city, there is no need to fill up the fuel tank. Because urban driving often stops, filling up the fuel tank will increase the engine load, but more fuel consumption.
