What is the fuel tank capacity of a heavy-duty truck in liters?

[RhettLee]

The fuel tank capacity of a heavy-duty truck is 140 liters. The size of the fuel tank determines the vehicle's ability to carry fuel, and the tank volume directly affects the driving range. For two vehicles with identical engines, the one with a larger fuel tank can travel farther. The functions of the fuel tank include: storing the working fluid required by the hydraulic system, as well as dissipating heat, settling impurities, and separating air bubbles from the liquid. The main components of the fuel tank are: the fuel tank cap, baffle, fuel gauge sensor, fuel inlet and return pipes, fuel filler neck, and vent. Important fueling precautions include: 1. Refuel when temperatures are relatively low; 2. If the vehicle is unused or rarely used for an extended period, maintain a low fuel level; 3. Avoid refueling when a fuel tanker is unloading; 4. Turn off the engine when refueling a gasoline vehicle; 5. Do not mix gasoline of different octane ratings. Long-term mixing of different gasoline grades can negatively impact the lifespan of the vehicle's ignition system, fuel injectors, and spark plugs.
