If driving in the city for a long time, it is best not to fill up the fuel tank, as a full tank can increase fuel consumption. The effects of filling up the fuel tank are as follows: 1. First refueling for a new car: It is best not to fill it up completely, as overfilling may cause the fuel gauge and sensor to malfunction, leading to inaccurate fuel gauge readings. Try not to overfill when refueling. 2. Harm to the carbon canister: The gasoline vehicle fuel vapor adsorption and desorption device, commonly known as the carbon canister, is a device that reduces the emission of gasoline vapors from the car fuel tank. If the tank is overfilled, there is no space at the top of the gasoline tank, leaving no place for the gasoline vapors to escape. As a result, liquid gasoline instead of gasoline vapors enters the carbon canister, causing harm to it. Since gasoline contains various harmful substances, long-term exposure to gasoline vapors can be harmful to health and may even lead to cancer.

What does vehicle torque mean?

Torque refers to the force that keeps the wheels rotating. For example, when a rotating tire is not continuously subjected to an external force, it will gradually stop rotating due to the influence of friction. Therefore, a force is needed to maintain the rotation of the wheel, and this force is torque. Information about torque: The greater the torque, the greater the power of the vehicle, the stronger the explosive force, the easier it is to pull heavy objects or climb slopes, and the better the instant acceleration performance. Of course, to obtain continuous acceleration capability, a large power is also required. The greater the power, the more energy is generated, allowing the vehicle to run faster.
