To open the fuel tank cap on the Envision, follow these steps: shift to P (Park) gear, then press the fuel tank cap from the outside to open it. Below is some relevant information about fuel tanks: 1. Fuel tanks can be divided into two types: open fuel tanks and closed fuel tanks. 2. Open fuel tank: The liquid surface in the tank is in contact with the atmosphere, and an air filter is installed on the fuel tank cap. Open fuel tanks have a simple structure and are easy to install and maintain, making them commonly used in hydraulic systems. 3. Closed fuel tank: Generally used for pressurized fuel tanks, filled with a certain pressure of inert gas, with a charging pressure of up to 0.05MPa. 4. Based on shape, fuel tanks can also be categorized into rectangular fuel tanks and cylindrical fuel tanks. 5. Rectangular fuel tanks are easy to manufacture and convenient for placing hydraulic components, hence widely adopted; cylindrical fuel tanks have high strength, are lightweight, and easy to clean, but are more difficult to manufacture and occupy more space, often used in large metallurgical equipment.
