1. The first half of the tank is heat-resistant, but the second half will run out soon! What the hell is going on here?

The first half of the tank is heat-resistant while the second half is not, mainly due to irregular shape of the fuel tank, limited measurement of the fuel gauge, psychological factors, and other factors such as temperature.. Specifically, the shape of the fuel tank is irregular: The fuel tank of a household car is not square, but is mechanically constrained to have an irregular shape, usually larger at the top and smaller at the bottom. The fuel gauge reflects the fuel level by measuring the height of the gasoline level in the tank through a float. When the tank is full, the upper space is large and the liquid level drops slowly; As the oil level decreases, the float sinks to the lower half with a smaller volume, causing the liquid level to drop quickly, giving the impression that the oil in the latter half of the tank is not heat-resistant. There are limitations to fuel tank measurement: the fuel gauge itself is not accurate: the fuel gauge data comes from the float inside the tank. When the tank is very full, the float is submerged in the oil until the liquid level drops to the maximum range of the float, and then the fuel gauge begins to drop, resulting in the first grid feeling more durable after filling up. Car companies are cautious about adjusting the fuel gauge: Some car companies raise the lowest position that the float can reach by a few centimeters to prevent car owners from breaking down. When the fuel gauge reaches the bottom, there is often still some fuel left in the tank, which can generally run another 50 to 80 kilometers. This also creates a sensory impression that the

liquid level drops slowly before and quickly after. Psychological factors: When the car owner first refuels, they have a sense of confidence and drive confidently, and do not pay much attention to the fuel gauge; After the fuel level decreases, people are more concerned about the remaining fuel level. By repeatedly checking the fuel gauge, they will feel that the fuel is used quickly, similar to the feeling of durability when a phone is fully charged, and the feeling of "rapid" decrease when the battery reaches 50%. Other factors such as temperature: thermal expansion and contraction effects: When driving continuously, the oil in the fuel tank expands due to heat, resulting in a decrease in density. At the same time, the resistance on the car fuel gauge will change due to temperature changes, causing measurement errors in the fuel level. However, this effect is generally very small and difficult to feel in the fuel tank of household vehicles. The non-linear relationship between fuel level height and actual fuel storage: When the fuel gauge shows that half of the gasoline is consumed, due to the irregular shape of the fuel tank, the car may actually consume more than half of the fuel. Moreover, the fuel gauge can only provide an approximate proportion of the remaining fuel, making it difficult to accurately determine "how many liters are left", while the fuel dispenser can accurately determine how many liters of fuel are added to the vehicle through the combination of a flow meter and pulse signals. In addition, there are some suggestions regarding car refueling and fuel tank usage: try not to wait for the oil lamp to light up before refueling: when the oil lamp is on, it indicates that the fuel level is lower than the f
