Generally speaking, the charcoal canister does not need to be replaced frequently. It only requires replacement if the interior becomes clogged or if carbon particles leak out. Causes of charcoal canister damage: Reasons for replacing a damaged charcoal canister: prolonged usage over many years. Another reason: overfilling the fuel tank after the pump nozzle automatically shuts off, which can force excess fuel into the canister and damage it. Therefore, once the fuel pump nozzle clicks off, do not attempt to add more fuel. Function of the charcoal canister: The charcoal canister is typically installed between the fuel tank and the engine. Since gasoline is a highly 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 escaping into the atmosphere. The activated charcoal canister storage device plays a crucial role in this process.

Will I get points deducted for driving over white road grid lines?

White road grid lines are channelizing lines and should not be driven over. Driving over them may result in various penalties. The following types of lines on the road must not be crossed: 1. Yellow solid lines: In China, yellow solid lines come in two types: double yellow lines and single yellow lines. They are prohibition lines, generally used to separate opposing traffic. Whether it's a double or single yellow line in the middle of the road, they must not be crossed. Driving over a yellow solid line will result in a fine of 200 RMB and 3 penalty points. 2. White solid lines: White solid lines are the most common road markings, used to separate lanes of traffic moving in the same direction. They help drivers navigate correctly on the road. White solid lines appear at intersections in various cities, standardizing driving routes and greatly improving traffic safety. When approaching a white solid line at a crossroad or T-junction, drivers should exit the lane before turning; otherwise, the rear wheels may cross the solid line. 3. Yellow grid lines: Yellow grid lines indicate no-stopping zones and are often found at the main entrances of government buildings. Parking is not allowed in areas marked with yellow grid lines, as it can disrupt traffic flow from the buildings and cause road congestion. Vehicles must not stop here but can pass through. Stopping on yellow grid lines may result in a 200 RMB fine if caught by traffic police. 4. Channelizing lines: These are V-shaped or triangular areas at intersections, designed to help drivers accurately determine directions for going straight or turning right, or to provide waiting areas for pedestrians at traffic lights. These markings are commonly found at highway ramps, multi-forked intersections, and complex crossroads, playing a crucial role in traffic guidance. Parking in these areas can confuse other drivers and may result in a fine starting from 100 RMB and 3 penalty points.
