What are the secrets of the car fuel tank? What do novices need to pay attention to when refueling? The oil tank on the car is a special container for storing hydraulic oil or hydraulic oil in the hydraulic system. Fuel tanks can be divided into open fuel tanks and closed fuel tanks. The fuel tank must have a large enough volume; The oil suction pipe and oil return pipe should be inserted below the minimum liquid level to prevent air bubbles from being generated by splashing of air suction and oil return; The distance between the oil suction pipe and the oil return pipe should be as far as possible.

Fuel tanks can be divided into open fuel tanks and closed fuel tanks. Open oil tank, the liquid level in the tank is communicated with the atmosphere, and the air filter is installed on the tank cover. Common fuel meters in automobiles are divided into electromagnetic, electrothermal and electronic types. The oil level sensors of these three fuel meters are all variable resistance type, which consists of a float and a variable resistor. The variable resistor is connected with the sliding arm of the variable resistor and installed in the oil tank. The float floating on it will change its position with the change of oil level. At the same time, the sliding arm and the variable resistance contact slide on the resistor, thus changing the series resistance value in the fuel gauge circuit.

After the car is used for a period of time, the fuel tank should be thoroughly cleaned and overhauled. When cleaning the fuel tank, wash the inside with hot water first, and then blow dry with compressed air to remove the gasoline vapor in the fuel tank. Then, put the gasoline tank into an aqueous solution containing 10% sodium hydroxide, and wash the inside and outside of the tank with flowing water after soaking. You can also wash it with 5% caustic soda boiling water solution and then wash it with hot water. If there is rust on the outside of the fuel tank, clean it with a wire brush and paint it. After cleaning the fuel tank, check the tightness. During inspection, all the orifices of the oil tank are plugged with rubber plugs, then immersed in water, and compressed air is input from the connecting hole of the oil pipe. If there is a bubble coming out of a certain part, it is a gas leak. At this point, mark the leakage, and then weld after paint removal.

Summer is the peak of electricity consumption. In order to distribute and use electricity reasonably, most of them will adopt the policy of power cut, but for production enterprises, it will undoubtedly affect the efficiency of work and production. Therefore, most enterprises will purchase various generator sets as backup power sources, such as diesel generator sets, Chongqing Cummins generator sets, Dongfeng Cummins generator sets, South Korea Daewoo generator sets and other brands to choose from. As a generator set, the most needed fuel is diesel, which is being installed.

The upper part of most fuel tanks is allowed to be close to the trunk or the back seat, so the shape of the upper part can be made regular, while the lower part of the fuel tank has to be made irregular due to the influence of exhaust pipe, suspension and other factors, so the volume of the lower part of the fuel tank is smaller than that of the upper part. Having said that, I believe friends will understand that the first half of oil is more durable than the second half.
