The fuel pump relay of the BYD S7 is located in the control cabinet or control box. Below is relevant information about the fuel pump relay: 1. Working principle: The fuel pump relay primarily functions by automatically closing its contacts when the vehicle reaches the specified oil pressure. This serves as a signal of normal oil pressure, which is then transmitted to CNC, PLC, etc., as a condition for allowing the equipment to start. 2. Function: When the pressure falls below the specified level, the pressure relay contacts will automatically open, cutting off the control circuit, triggering an alarm, and causing the vehicle equipment to stop working automatically to protect the safety of passengers and the equipment on board.

How Far Can 2 Liters of Gasoline Take You?

Two bars of fuel can cover approximately 60 kilometers. Below are specific details about car fuel tank capacity: Meaning of the Fuel Gauge: The fuel gauge on the dashboard has 5-6 bars, with each bar representing the remaining fuel capacity in the tank. Generally, when the fuel gauge shows two bars remaining, it's time to refuel. Fuel Tank Capacity Units: The international standard uses liters (L) as the unit for measuring car fuel tank capacity, with different countries having their own corresponding standards. Relationship Between Engine Displacement and Fuel Tank Volume: Typically, small cars have a fuel tank capacity of 35-45 liters, while medium-sized cars have a capacity of around 55-75 liters. A full tank generally allows for a driving range of about 500 kilometers. Depending on the engine displacement, lighter vehicles with smaller engines have correspondingly smaller fuel tank volumes, whereas heavier vehicles with larger engines have larger fuel tank volumes.

The interior design is dignified, grand, and luxurious, with the driver's instrument panel and steering wheel featuring more traditional designs. The 12.3-inch instrument cluster comes with naked-eye 3D functionality, offering excellent display effects and instantly enhancing the sense of technology. 3. Most functions are integrated into the central large screen. To avoid obstructing the driver's view, the central screen is even more flattened than a 16:9 aspect ratio and divides the UI interface into three sections.
