The reasons for no air in the first, second, and third gears of the air conditioner are as follows: 1. Evaporator box air leakage: If there is air leakage at the connection between the evaporator box shell and the air duct, the cold air originally released from the air conditioner vent will continuously leak from the air leakage point, resulting in a reduced air volume from the air conditioner vent. 2. Air filter: The air filter is located at the air intake of the blower. All cold or hot air blown out from the car air conditioner must pass through the air filter. However, the air filter is also prone to accumulating dirt. If the owner does not replace the air filter in time, a large amount of dust can easily adhere to the air filter, and these impurities will naturally reduce the gas flow passing through the air filter. 3. Poor sealing of the air duct: The air conditioner vent is connected to the blower via an additional air duct. If the sealing of the additional air duct deteriorates, air leakage will occur, and the air volume from the air conditioner vent will decrease.

What are the length, width, and height of the Baojun 530 in meters?

The length, width, and height dimensions of the Baojun 530 are 4695mm/1835mm/1750mm, which are the official data. The length of the Baojun 530 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The naturally aspirated engine of the Baojun 530 has a maximum power of 108kW and a maximum torque of 250 Nm. The engine's maximum power speed is 5200 rpm, and the maximum torque speed ranges from 2200 to 3400 rpm. It is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head. This engine is paired with a 6-speed manual transmission. There are national regulations regarding vehicle dimensions. According to the national standard 'GB1589-89,' the total width of a vehicle does not include the rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.

Lifespan of Audi's Wet Dual-Clutch Transmission?

Audi's wet dual-clutch transmission has a lifespan of approximately 20 years or 500,000 kilometers. Here are the specific details: 1. Dual-clutch transmissions are divided into two types: dry dual-clutch and wet dual-clutch. Both operate by having two clutches alternately switch gears. 2. Dry dual-clutch transmissions provide more direct power transmission: Dry dual-clutch transmissions use direct contact between metal plates for power transmission, resulting in more direct power transfer. When the metal plates are pressed together, the transmission ratio increases, leading to significant transmission efficiency. In contrast, wet dual-clutch transmissions are immersed in oil, which increases transmission resistance. Additionally, dry dual-clutch transmissions use air cooling, while wet dual-clutch transmissions use liquid cooling, making the latter more efficient in heat dissipation. 3. The medium for power transmission between the driving and driven plates differs between dry and wet dual-clutch transmissions: Dry dual-clutch transmissions use air, while wet dual-clutch transmissions use oil.
