Should the External Air Circulation Be Turned Off When Parking the Vehicle?

It is not necessary to turn off the external air circulation system when parking the vehicle. Doing so can lead to poor air circulation inside the car. Recirculating air inside the vehicle can cause the windows to fog up, which may reduce driving safety. Therefore, when temporarily parking the vehicle, it is essential to keep the external air circulation on or turn off the air conditioning system. Different vehicle models have different control methods, which can be divided into two types: The first control method involves buttons. The air conditioning control panel has buttons for internal circulation and external circulation. To use either system, simply press the corresponding button for internal or external circulation. The second control method uses a single button that toggles between internal and external circulation systems. When the button's light is on, it indicates the internal circulation system is active. The internal circulation system should be used when the air conditioning is on or when external odors are strong, effectively preventing outside air from entering the vehicle. Choosing between internal and external circulation depends on the following scenarios: Road conditions: On highways, use external circulation. Due to wind resistance and high speeds, opening windows is not advisable. Prolonged use of internal circulation can lead to hypoxia, impairing reaction and judgment, which is dangerous. Additionally, air quality on highways is generally good, with low exhaust concentrations, making external circulation suitable. In congested urban areas or during rush hours, where exhaust concentrations are high, switch to internal circulation. Vehicle condition: New vehicles often contain high levels of toxic gases like formaldehyde. For the first three to six months after purchase, it is recommended to use external circulation along with opening windows to enhance air circulation and dilute toxic gas concentrations. Air quality: In areas with severe PM2.5 pollution (above 50), where air quality is not good, it is advisable to use internal circulation to avoid inhaling excessive PM2.5 particles. Function of external circulation: External circulation ventilates the car, expelling stale, oxygen-depleted air and bringing in fresh air. In winter, if the heater is on, remember to switch to external circulation to prevent dizziness and chest tightness. Function of internal circulation: Use internal circulation during traffic jams or on dusty roads. Close the windows and switch to internal circulation to block external airflow. When parking, it is best to set the system to internal circulation. On long highway drives, if the air inside becomes stale, switch to external circulation. The use of internal and external circulation should be coordinated with the air conditioning and heating systems.

What does it mean when a motorcycle engine seizes?

Engine seizure is a severe mechanical failure caused by lack of engine oil, clogged oil passages or filters, or oil pump damage in the engine. It occurs when the cylinder block, piston, and piston rings melt and fuse together due to high-temperature friction without oil lubrication. Below are relevant explanations: 1. Oil-related issues: This severe mechanical failure is caused by insufficient engine oil, clogged oil passages or filters, or oil pump damage, resulting in the cylinder block, piston, and piston rings melting and bonding together due to high-temperature friction without oil lubrication. 2. Cooling problems: When a motorcycle's temperature becomes excessively high, engine seizure can occur. Therefore, motorcycle RPM should not be too high, as it can easily cause the engine's operating temperature to exceed the originally designed tolerable limit. When the engine block temperature is too high, with surface temperatures exceeding 90°C.

What does 'full tire wear' mean for motorcycles?

Tire wear marks extend to the edge of the tire, commonly referred to as aggressive cornering where the tire is fully worn. Below are relevant details about tires: 1. Wear: Tires have wear indicators; there are triangular marks on the sidewall, and it is recommended to replace the tire when wear reaches the point indicated by the triangle. Inside the tire tread grooves, there are also raised markers—when wear reaches these markers level with the tire surface, replacement is necessary. Simple punctures can be repaired without needing replacement, but bulges must be replaced. 2. Aging: Rubber oxidizes in the air, and oxidized rubber hardens, reducing grip. Therefore, even unused tires will have a reduced lifespan. It is not recommended to use tires for more than 5 years from the production date, which is marked on the tire sidewall.

Do motorcycles require annual inspection?

Motorcycles also require annual inspection. Here are the relevant details: 1. Mandatory inspection vehicles: Motorcycles fall under mandatory inspection vehicles. The new policy states that newly registered motorcycles within 6 years do not need on-site inspection. Owners should collect the inspection-exempt mark in the 2nd, 4th, and 5th years. Motorcycles older than 6 years must undergo on-site inspection and participate in annual inspection once every year as required. If the inspection fails, the motorcycle cannot be driven on the road. In severe cases, the motorcycle may directly lose its road qualification and be scrapped. 2. Documents: For motorcycle annual inspection, owners only need to bring their driver's license, vehicle license, and compulsory traffic accident liability insurance policy to participate.

Is it necessary to display the 2022 vehicle inspection sticker on the car?

It is not required to display the 2022 vehicle inspection sticker on the car. Here are the relevant details: 1. Inspection reform: Vehicle inspection information is now interconnected. During roadside checks, traffic police can use PDAs to access the vehicle monitoring system, which will provide early warnings for approaching vehicles that have not undergone inspection, eliminating the need for visual verification of inspection information. 2. Changes in inspection: There is no longer a need to obtain a paper inspection sticker, meaning it does not have to be affixed to the car's windshield. However, it is important to note that vehicle owners must apply for an electronic inspection certificate every two years. Since paper inspection stickers have been replaced by electronic inspection certificates, vehicles that pass the regular inspection may still receive a paper inspection sticker from the inspection agency, while the electronic certificate can be viewed on a mobile phone. The decision to display the paper inspection sticker is optional.
