Do Cars Have Reserve Fuel?
1 Answers
Currently, most household cars or many trucks do not have reserve fuel in the strict sense. When the fuel gauge yellow light comes on, it indicates that the reserve fuel has been activated, which is the fuel at the bottom of the fuel tank. Reserve fuel was a design feature of some early vehicles, essentially consisting of a special auxiliary fuel tank attached next to the main fuel tank. This auxiliary tank was usually kept closed during normal operation and had a conduit that would activate when fuel ran out. Additionally, regarding reserve gasoline, it's important to note: Carrying reserve gasoline in a car is illegal. Gasoline can cause explosions in containers, which is extremely dangerous. During driving, the inner walls of plastic containers can generate static electricity through frequent friction with the gasoline inside. When static electricity accumulates to a certain level in an insulated plastic container, it discharges in the form of sparks. These sparks can ignite the mixture of air and gasoline vapor inside the container, leading to catastrophic consequences. Therefore, for personal safety, it is prohibited to carry additional gasoline during road trips.
