What is the reason why the Civic's AC only blows air but does not cool?

Is the 1.8T transmission in the Boyue dry or wet?

The 1.8T transmission in the Boyue is wet. Differences between dry and wet transmissions: The working environment of the clutch differs between the two. In a wet transmission, the clutch is immersed in transmission fluid, which acts as an intermediary to connect with the engine. In a dry transmission, the clutch directly contacts the engine flywheel. Response speed: Dry transmissions perform better than wet ones. Because dry transmissions involve direct contact for power transfer, the transmission is more immediate. The metal plates are pressed tightly, increasing the transmission ratio, resulting in more direct and noticeable effects. Wet transmissions require an additional step—from the driving disc speeding up to the increased centrifugal force of the fluid, and then to the driven disc speeding up—so the response speed is slightly slower. Transmission: Refers to the vehicle's transmission system, which is divided into manual and automatic types. Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, achieving speed and torque changes through hydraulic power transfer and gear combinations.

How Long Should a Car Warm Up in Winter?

In winter, a car can be driven after warming up for 30 seconds to one minute. Below is an introduction to car warm-up: 1. The correct warm-up method is to start driving after 30 seconds to one minute of idling, but avoid driving at high RPMs at this time. Maintain a low speed with the engine RPM not exceeding 3000, generally keeping it around 2000. Otherwise, the severe wear on the engine and transmission may be irreversible. Once the engine temperature rises to the normal operating temperature (which usually takes 3 to 5 minutes), normal driving can resume. 2. Driving immediately after starting the car is harmful. When starting the vehicle, you may notice that the tachometer needle briefly stays at a position more than double the normal idle RPM (this is more noticeable in automatic transmission cars). This happens because the modern car's computer control module (commonly known as ECU) instructs the fuel injection system to inject more fuel into the cylinders to increase the engine RPM, allowing the engine to warm up quickly in cold conditions. The extent to which the cold-start RPM increases depends on the external ambient temperature and the ECU settings for each specific car model, meaning not all cars will have the same RPM value. Under normal circumstances, the engine RPM will drop significantly within one minute of a cold start.

Where is the transmission oil filler port of Chery Fengyun 2?

The transmission oil filler port is located on the transmission oil pan. There is a yellow ring at the top left corner of the engine, and below the yellow ring is a nut. Hold this ring and unscrew it to add transmission oil. Transmission oil replacement cycle: The oil change interval is generally two years or 40,000-60,000 kilometers. During normal use, the working temperature of transmission oil is usually around 120 degrees Celsius, so the quality requirements for the oil are very high, and it must be kept clean. It is usually difficult to determine whether the oil needs to be changed by visual inspection or touch. However, after long-term use, the oil will accumulate a large amount of impurities. If the oil is not replaced in time, these impurities will wear the engine over time and shorten the lifespan of the vehicle. Transmission oil replacement method: A better oil change method is dynamic oil change, which uses a dedicated transmission cleaning device. During the operation of the transmission, the old oil is fully circulated and discharged, and then new transmission oil is added, achieving an oil change rate of over 90% and ensuring a good oil change effect. Function of transmission oil: Transmission oil is an oil product that keeps the gear system clean, lubricates and extends the life of the transmission device, and has anti-low temperature properties, providing effective lubrication even at low temperatures. It reduces oil loss under harsh operating conditions. Depending on the structure of the transmission, transmission oil is divided into automatic transmission oil and manual transmission oil.

What are the performance features of the Audi A3?

Audi A3 performance is equipped with 1.4T and 1.8T engines, paired with a 6-speed manual transmission or 7-speed Stronic dual-clutch transmission. Key advantages: abundant power. Main disadvantages: lower configuration, not cost-effective. Handling: The Audi A3 has a solid chassis; the entire lineup is matched with a 7-speed dual-clutch transmission and a manual-automatic integrated gearbox; the steering wheel is light; the suspension is firm; gear shifting is smooth without any jerking; road feedback is clear; the chassis tuning is quite firm; however, wind noise becomes noticeable at high speeds. Power: The Audi A3 delivers strong overall performance with quick acceleration. Fuel consumption: According to feedback from most users, the Audi A3's average fuel consumption is around 10 liters per 100 kilometers.

Why is the Subject One Test Reservation Still Under Processing?

There are several possible reasons why the driving test reservation shows as under processing: The reservation deadline has not yet been reached. The number of reservations has not reached the predetermined quota, causing the deadline to be postponed. For online Subject One test reservations, the result (success or failure) is usually displayed within 24 hours after submission. If the page continues to show "under processing," it means the reservation was unsuccessful, and you need to cancel and resubmit the reservation. For first-time Subject One test reservations, the order is based on the submission time. If a reservation is canceled due to personal reasons after being successfully booked, the order is based on the cancellation time. For non-first-time reservations, the order is based on the previous test time, unless canceled for reasons beyond the applicant's control (e.g., power outage at the testing center, network failure preventing completion of the test), in which case the ranking time remains unchanged. For Subject Two and Subject Three road driving skill tests, the number of attempts must not exceed five times each (i.e., a total of ten test opportunities). If the Subject Two test shows as "under processing," it means the system has received the reservation request and is scheduling the date and session for applicants. If it remains in this status for an extended period, it indicates the request has been pushed out due to exceeding the available slots.

How to Start with One-Button Start?

The method to start a car with one-button start: After the owner opens the door and enters the car, press the brake and lightly press the one-button start button to start the car. Here are the advantages of the car's one-button start: 1. Unlike the traditional mechanical key ignition method and the traditional starting procedure, simply pressing the one-button start button can start or turn off the engine, avoiding the hassle of losing or searching for keys. Most of the time, the brake pedal needs to be pressed during the ignition process. 2. The starting button procedure is entirely controlled by a chip for conversion, ensuring stable and reliable performance. It simulates the original car key starting mode OFF-ACC-ON-START-ON-OFF, normally achieving each function. 3. Intelligent sensing entry (opening the door)—When approaching the vehicle, the RFID intelligent detection system will automatically unlock the door within a range of 1.0-2.0 meters. The sensing distance is stable and non-directional, accompanied by flashing turn signals and a short honk with light and sound prompts. When approaching the door at a normal speed, the system will automatically unlock. 4. Intelligent sensing entry (closing the door)—When leaving the vehicle, if the RFID detection system cannot find the signal of the "smart key" within the set range, it will immediately lock all four doors. At the same time, the turn signals will flash, and a short honk will sound to remind the owner that the vehicle has automatically entered the anti-theft state.
