What is the optimal position for adjusting car rearview mirrors?

What are the reasons for a car air conditioner hissing and not cooling?

Car air conditioner hissing and not cooling reasons are: 1. Lack of refrigerant, leading to insufficient refrigerant in the air conditioning system pipelines and reduced pressure; 2. Long-term lack of maintenance, causing clogged air filters and condensers; 3. Air conditioning compressor failure; 4. Loose compressor drive belt, reducing compressor speed; 5. Poor remote control or faulty air conditioning receiver; 6. Four-way valve or compressor high-low pressure gas mixing, rendering the air conditioning ineffective. The air conditioner is used to adjust and control the temperature, humidity, air cleanliness, and airflow within the car cabin to an optimal state. Functions of the air conditioner: 1. Achieve cooling effect through the continuous phase change cycle of refrigerant; 2. Remove dust, odors, smoke, and toxic gases from the car's air, making the interior air fresh; 3. Humidify the car's air, increasing the relative humidity inside the vehicle.

What is the solution for transmission overheating alarm?

The solutions for transmission overheating alarm are: 1. Repair the engine; 2. Clean the radiator; 3. Fix the torque converter; 4. Repair the valve body or replace the oil pump; 5. Replace the thermostat. The causes of transmission overheating alarm are: 1. Insufficient flow in the transmission cooling oil circuit; 2. Transmission clutch slipping; 3. High engine and coolant temperature; 4. Blocked radiator grille; 5. Thermostat sticking. The functions of the transmission are: 1. Change the transmission ratio to expand the range of torque and speed changes of the driving wheels; 2. Adapt to frequently changing driving conditions, allowing the engine to work under favorable conditions; 3. Enable the vehicle to reverse while the engine rotation direction remains unchanged; 4. Utilize neutral gear to interrupt power transmission, facilitating gear shifting or power output.

What emission standard does LV represent?

LV represents the China IV emission standard. The main pollutants emitted by vehicles include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, these pollutants are controlled and reduced to levels below the specified standards. Methods to distinguish vehicle emission standards include: 1. Checking the vehicle's environmental protection label; 2. Querying on the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center; 3. Checking the vehicle's factory certificate; 4. Roughly identifying based on the year of vehicle registration; 5. Querying at the vehicle management office with the motor vehicle registration certificate.

What grade of gasoline does the Lexus UX use?

Lexus UX uses 92-octane gasoline. 92-octane gasoline is composed of 92% isooctane and 8% n-heptane. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum, used as fuel, and appears as a transparent liquid. Taking the 2020 Lexus UX as an example, its front suspension is a MacPherson independent suspension, the rear suspension is a multi-link independent suspension, equipped with a 2.0L naturally aspirated engine, with a maximum horsepower of 173ps, maximum torque of 207Nm, and maximum power of 127kW.

Can Mercedes-Benz Cars Use 92 Octane Gasoline?

Mercedes-Benz cars cannot use 92 octane gasoline. According to the official vehicle manual, Mercedes-Benz models should use 95 octane gasoline. In addition to checking the recommended gasoline grade in the vehicle manual, you can also find it on the fuel tank cap, which will indicate the appropriate octane rating. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Cars with a compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the required gasoline grade, as high-compression engines can also be tuned to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you accidentally use the wrong gasoline grade in a Mercedes-Benz, simply switch back to the correct grade after the current tank is used up. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles designed for lower octane gasoline, using higher octane gasoline will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in extreme cases.

How Long Does It Usually Take to Receive a Notification After Running a Red Light?

After running a red light, the illegal photo notification SMS is usually received within 3 to 7 days, and at the latest, within about 13 days. However, some cities now offer "instant electronic police capture alerts," where you can receive an SMS notification within 5-10 minutes of being captured. However, the notification does not equate to a traffic violation; it serves only as a capture alert. The final determination of whether it constitutes a violation still takes 3-7 days. If it is indeed a violation, you will receive another SMS notification. For traffic violations captured by surveillance cameras, vehicle owners generally do not receive an immediate violation SMS; there is a delay, and the duration may vary. This is because after an electronic camera captures a violation, the relevant violation information needs to be transmitted through a dedicated channel to the traffic police management center, where it is compiled and then verified by relevant staff. Once confirmed as a violation, the system automatically retrieves the vehicle owner's phone number based on the license plate information and sends the violation details via SMS. Only then does the owner receive the corresponding violation SMS. After receiving the violation SMS, the vehicle owner must go to the traffic police department where the violation occurred to handle the matter within one month before the vehicle's annual inspection. Generally, if a vehicle owner suspects a violation, they can use 15 days as a benchmark. If no violation SMS is received beyond 15 days, it is likely that no violation was recorded. Traffic Violation Query Methods: Traffic violation queries refer to checking motor vehicle violations of traffic management regulations through online platforms or query terminals. Methods for querying vehicle violations include website queries, phone queries, SMS queries, and mobile app queries. Website Query: You can search for "vehicle violation query" and enter your vehicle information to check. Phone Query: To inquire about violations, you can call the local 114 (area code + 114) or 12580 for confirmation. Violations can only be processed at the traffic police department where the violation occurred or where the vehicle's license plate was issued. For on-the-spot violations, such as those directly caught by a traffic officer, they must be handled at the location of the violation. SMS Query: Open your phone's SMS interface; enter the violating license plate number and color in the message content; input 1062650001 as the recipient and click send. Mobile App Query: Open the Traffic Management 12123 app, select "violation query," and find unresolved violations to clear them.
