Car air conditioning not cooling in high temperatures is due to a lack of refrigerant. The following is a related introduction to car air conditioning: 1. Air conditioning layout: Different types of air conditioning systems have different layout methods. Currently, cars widely use integrated heating and cooling air conditioning systems. The layout form involves assembling the evaporator, heater radiator, centrifugal fan, and control mechanism together, known as the air conditioning unit assembly. 2. Air conditioning components: Modern air conditioning systems consist of refrigeration systems, heating systems, ventilation and air purification devices, and control systems. Car air conditioning generally includes the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller, and control system. Car air conditioning is divided into high-pressure and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, condenser, receiver-drier, and liquid pipelines; the low-pressure side includes the evaporator, accumulator, return pipelines, compressor input side, and compressor oil pan.

What Does the Driving Test Subject 2 Include?

The C1 and C2 license tests include five mandatory items: reverse parking, parallel parking, hill start and stop, right-angle turn, and S-curve driving (commonly known as the S-bend). Some regions may also include a sixth item: highway toll card collection. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), starting from June 1, 2021, the hill start and stop test was removed for C2 and C5 license applicants in Subject 2. However, for large vehicle licenses (A and B), Subject 2 includes 16 items: reverse parking, continuous obstacle course, S-curve driving, highway simulation test, narrow gate, bumpy road, single-plank bridge, narrow road U-turn, hill start and stop, parallel parking, highway emergency handling, mountain road simulation, right-angle turn, rain and fog weather simulation, highway tire blowout, and tunnel simulation driving. For small vehicles, a passing score is 90. The Subject 2 driving test is scored out of 100, with criteria for failure, 20-point deductions, 10-point deductions, and 5-point deductions. The following rules apply for passing: applicants for large buses, trailers, city buses, medium buses, and large trucks must score at least 90; applicants for other license types must score at least 80. Article 44 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" states that each test subject can be taken once, with one retake allowed if the initial attempt fails. If the retake is not taken or fails, the test session ends, and the applicant must reschedule. Within the validity period of the learner's permit, the number of attempts for Subject 2 and Subject 3 practical tests must not exceed five. If the fifth attempt fails, previously passed test scores for other subjects become invalid. According to the "Road Traffic Safety Law": Article 19 states that driving a motor vehicle requires a valid driving license. Applicants must meet the driving permit conditions set by the public security department under the State Council. Upon passing the test, the traffic management department of the public security authority issues the corresponding category of driving license. Drivers must operate vehicles within the scope of their license and carry their driving license while driving. Therefore, it is clear that both driving without a license and driving a vehicle not covered by the license are illegal. As per the State Council Legislative Affairs Office's reply to the "Interpretation of the 'Road Traffic Safety Law' and Its Implementing Regulations": driving a vehicle not covered by the license is considered unlicensed driving. Penalties may be adjusted based on the principle of proportionality, with lighter penalties possible compared to unlicensed driving. Thus, both unlicensed driving and driving a vehicle not covered by the license fall under Article 99, Paragraph 1 of the "Road Traffic Safety Law": driving without a license, with a revoked license, or during a suspension period may result in fines and up to 15 days of detention by the traffic management department.

Is the Audi Q2L equipped with a wet dual-clutch transmission?

Audi Q2L uses a dry dual-clutch transmission. Since Audi and Volkswagen share common parts, it is natural that this dual-clutch transmission also comes from Volkswagen. Dual-Clutch Transmission: Dual-clutch transmissions can be divided into dry and wet types. In principle, both are the same, but structurally, there are differences mainly in the clutch part and internal gear ratios. Within the Volkswagen Group, the 7-speed dry dual-clutch is mainly paired with the 1.4T engine, while the 7-speed wet dual-clutch is mainly paired with the 2.0T engine. Audi Q2L: In terms of exterior design, the Audi Q2L features the brand's signature hexagonal grille and is equipped with T-shaped LED daytime running lights in the headlights. The front bumper is further accentuated with a silver trim, giving the car a sporty and stylish appearance. In terms of dimensions, the Audi Q2L measures 4190mm in length, 1790mm in width, and 1510mm in height, with a wheelbase of 2600mm. It is positioned as a compact SUV, and the domestically produced Q2L will undergo further lengthening. At the rear, the Audi Q2L also features T-shaped LED taillights, combining style and robustness.

How to Start the Vehicle with a Remote Key?

There is a semicircular arrow circle on the car key with '2X' or 'A' written inside. Press it quickly twice to start the vehicle. Below is a brief introduction on using a car remote key: 1. Avoid contact with strong magnetic fields: For example, try to avoid parking the vehicle in places with strong magnetic signals such as high-voltage lines or transmission towers, as smart keys use low-intensity radio waves and may not function properly under magnetic interference. 2. Avoid contact with the ground: Try not to drop or throw the smart key when using it. Although most smart key shells are quite sturdy, frequent dropping can lead to poor battery contact inside.

What does the Dongfeng Honda Inspire recall mean?

Dongfeng Honda Inspire recall refers to Dongfeng Honda Automobile Co., Ltd. filing a recall plan with the State Administration for Market Regulation in accordance with the requirements of the Regulations on the Management of Defective Automobile Product Recalls and the Implementation Measures of the Regulations on the Management of Defective Automobile Product Recalls. The recall is due to the air velocity design at the outlet of the vehicle's intercooler. When driving in high-temperature and high-humidity environments such as heavy rain, a small amount of condensed water may accumulate at the intercooler outlet. During rapid acceleration, condensed water droplets may be sucked into the combustion chamber, causing engine misfire. In extreme cases, this may trigger engine protection, leading to engine stalling.
