Incorrect fuel tank ventilation in Volkswagen may be caused by a clogged activated charcoal canister or charcoal canister solenoid valve. Introduction to the fuel tank: The fuel tank is a container for storing fuel in aircraft or automobiles, and it is also a specialized container for storing hydraulic oil or hydraulic fluid in hydraulic systems. Fuel tanks can be divided into two types: open tanks and closed tanks. The fuel tank must have a sufficiently large volume. To maintain oil cleanliness, the tank should have a sealed cover with an air filter installed on it. The bottom of the tank should be at least 150mm above the ground, and sufficient attention should be paid to the anti-corrosion treatment of the inner surface of the tank. Calculation of fuel tank volume: The fuel tank volume is calculated using the formula length x width x height. Taking a regular rectangular fuel tank as an example, with a width of 58cm, height of 58cm, and length of 110cm, the tank capacity = 58 x 58 x 110 = 370,040 cubic centimeters. Since 1 liter = 1,000 cubic centimeters, the capacity is approximately 370 liters. The standard fuel tank volume indicated in the vehicle specifications is not the maximum fuel tank capacity. According to international standards, L (liter) is used as the unit of measurement for automobile fuel tank capacity, and different countries and regions also have corresponding standards for automobile fuel tank capacity.
