Should the fuel tank of a new car be filled up?
1 Answers
It is not advisable to fill up the fuel tank of a new car, as it may cause the fuel float and sensor to malfunction, leading to inaccurate fuel gauge readings. Overfilling the fuel tank can have the following effects: 1. Risk of fire hazard: When the tank is overfilled, the expansion of gasoline can rupture the tank. If overfilled, gasoline may overflow through the vent hole, and if exposed to an open flame, it can ignite instantly; 2. Blockage of the vent hole: If the vent hole is blocked, negative pressure will form inside the fuel tank, resulting in poor fuel supply or even a complete fuel supply failure; 3. Damage to vehicle components: Overfilling the fuel tank increases the overall weight of the car, leading to higher fuel consumption. Additionally, excessive fuel can enter the pipelines, harming the carbon canister and flowing into the intake manifold, causing the spark plugs to malfunction and potentially preventing the vehicle from starting.
