How Full Should the Fuel Tank Be in Summer?
2 Answers
It is appropriate to stop when the fuel nozzle automatically shuts off. Here are the relevant explanations: 1. Gasoline evaporation is unpleasant and carcinogenic: The activated carbon canister is usually located near the fresh air intake for the exterior circulation. When the tank is overfilled, the carbon canister becomes saturated, and excessive pressure leads to venting, allowing air containing gasoline components to enter the cabin, which can affect the health and safety of the driver and passengers. 2. Damage to the carbon canister: If the tank is overfilled, liquid gasoline instead of gasoline vapor may enter the carbon canister, causing damage. The carbon canister is typically installed between the fuel tank and the engine. Since gasoline is a volatile liquid, the fuel tank often contains vapor at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from evaporating into the atmosphere. The activated carbon canister storage device plays a crucial role in this process.
As a veteran driver with nearly 30 years of experience, I often remind my friends not to let the fuel tank run too low in summer. High temperatures cause gasoline to evaporate much faster. If the fuel level is too low, air can easily enter the tank, leading to rust and corrosion of internal metal components, and may even cause starting difficulties or stalling. I always make it a habit to keep the tank around half full, preferably between 1/4 and 1/2, as this reduces evaporation loss and prevents engine issues. Additionally, it's important to check if the fuel cap is tightly sealed to prevent dust or moisture from entering. Remember to check the fuel gauge before regularly filling up—these small habits can protect your vehicle's lifespan and save you money and hassle in the long run. In short, when driving in summer, safety comes first, and maintaining a moderate fuel level is the most reliable approach.
