In straight-line driving, the 30 cm distance can be judged by observing the left reinforcement rib of the car hood, the left wiper, the one-third point of the car hood, or the door handle in the rearview mirror. Here are the specific methods: Observe the left reinforcement rib of the car hood: This refers to the raised line on the left side of the car hood. When the left reinforcement rib aligns with the center of the lane, the distance between the car body and the sideline is approximately 30 cm. Observe the left wiper: Align the raised part of the left wiper with the white line on the right side of the ground, and then confirm by checking the right rearview mirror.

What is a Dust Filter?

Dust filter is a device that works in conjunction with the charcoal canister, installed at the end of the pipe leading from the charcoal canister to the atmosphere. Below is relevant information about dust filters: Functions of a dust filter: Maintains air pressure balance and absorbs fuel vapor. The engine's fuel supply relies on the fuel pump drawing gasoline from the fuel tank. Without an external air passage, the fuel tank would remain in a negative pressure state, which would progressively increase, causing the tank to collapse and deform. Simultaneously, the working resistance and load on the fuel pump would continuously rise, potentially leading to severe cases where the fuel pump could burn out, and the sliding rod of the fuel level sensor could be crushed and deformed. Methods to extend the service life of a dust filter: Generally, the service life of an activated charcoal canister is quite long, and manufacturers typically do not recommend regular replacement of the charcoal canister. However, due to environmental factors, the ventilation pipe is prone to clogging from dust and debris. Therefore, installing a dust filter on the ventilation pipe can help prolong the effectiveness and service life of the charcoal canister.

Can a New Car Be Replaced If It Has Been Soaked in Water?

New cars cannot be replaced if they have been soaked in water. Below are the impacts of a water-damaged car. 1. Electronic System Failure: The most vulnerable component in a car to water damage is the electronic system. Although modern vehicles have waterproofing measures for electronic circuits, they cannot withstand heavy or prolonged water exposure. If water remains in the engine compartment for an extended period, it may cause wire corrosion and short circuits, leading to electronic malfunctions or even spontaneous combustion. 2. Engine Failure: Generally, if water has entered the engine compartment, do not attempt to start the car. There is no guarantee that the engine is free from water ingress, and starting it directly could result in complete engine failure. 3. Transmission Failure: The depreciation of a water-damaged car largely stems from transmission issues. Transmissions have vent holes to relieve pressure caused by temperature changes, usually located at the top of the transmission. If water levels rise high enough to submerge the engine compartment, water may enter the transmission. This can lead to problems such as slipping, shaking, or gear-shifting jerks, and in severe cases, the transmission may require major repairs. 4. Interior Mold Growth: Rainwater contains numerous impurities, and a soaked car interior creates an extremely humid environment prone to mold growth. If the vehicle is not dried promptly, mold can damage fabric and leather upholstery and produce unpleasant odors.
