For turbocharged cars, it is best not to turn them off directly. Before shutting down, let the engine idle for 3 minutes to allow the turbo to cool down, which helps protect the turbo. Below is some relevant information about turbocharging: 1. The main difference between turbocharging and gas turbines: The turbocharging unit does not have a combustion chamber or corresponding systems. The turbo utilizes the exhaust energy of a reciprocating internal combustion engine, and the compressed air provided by the centrifugal compressor serves as the charge for the reciprocating internal combustion engine. In a turbocharger, the compressor impeller and the turbine are assembled on the same rotating shaft, called the rotor. Other components such as seals and thrust washers are also mounted on the same rotor shaft and rotate together. 2. Classification of turbocharging technologies: The main turbocharging technologies currently include mixed-flow turbocharging technology, variable turbocharging technology, two-stage turbocharging technology, and electrically assisted turbocharging technology.

Small passenger vehicles must have a seating capacity of 9 or fewer. Individuals with disabilities in the right lower limb or both lower limbs can apply for a special driving license for small automatic transmission passenger vehicles designed for the disabled, designated as C5. The vehicles they can drive include small and micro automatic transmission passenger vehicles specifically for the disabled. The restriction to small passenger vehicles primarily addresses the travel needs of disabled individuals, and for now, it does not include cargo vehicles involved in commercial operations. The limitation to automatic transmission vehicles is mainly due to their ease of operation, which is the international standard for disabled drivers. According to the "Motor Vehicle Driving License Business Operation Specifications" issued by the relevant authorities, motor vehicle driving licenses are classified into 15 levels: A1, A2, A3, B1, B2, C1, C2, C3, C4, D, E, F, M, N, and P.

Is it necessary to use turn signals when reversing into or exiting the parking space in Subject 2?

When reversing into or exiting the parking space in Subject 2, it is not necessary to use turn signals. There are a total of 6 instances in Subject 2 where turn signals are required, which are: When starting the vehicle, turn on the left turn signal; When starting on the slope, turn on the left turn signal; When parallel parking, turn on the right turn signal as the vehicle passes the side parking space and prepares to reverse at a distance of 30 cm from the side line; Before shifting into reverse gear during parallel parking, turn on the left turn signal because the steering wheel will be turned fully to the right during reversing, causing the front of the vehicle to shift left; Before exiting the parallel parking space, shift into drive gear and turn on the left turn signal, then turn it off promptly after exiting; When entering the area for a right-angle turn, turn on the left turn signal and turn it off promptly after completing the turn. Penalties for incorrect use of turn signals are as follows: Failing to use or incorrectly using turn signals before starting, turning, changing lanes, overtaking, or parking will result in a deduction of 10 points. Turning the steering wheel within less than 3 seconds after turning on the turn signal before starting, turning, changing lanes, overtaking, or parking will result in a deduction of 10 points. The full score for Subject 2 is 100 points, with assessment criteria set for disqualification, deductions of 20 points, 10 points, or 5 points. The test is considered passed under the following conditions: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for small vehicles C1 and C2 include reversing into a parking space, parallel parking, slope parking and starting (canceled for C2), right-angle turns, and curve driving (commonly known as S-curves) as the five mandatory items (some regions include a sixth item, high-speed card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include stake test, slope parking and starting, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, limited-width gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turns, as well as simulated highway driving, continuous sharp mountain road turns, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling.

How Long After Passing C1 Subject 1 Can You Take Subject 2?

For a C1 driver's license, you can schedule the Subject 2 test online 10 days after passing Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the registration requirements for Subject 2 include completing 26 study hours: 2 hours of theoretical knowledge, 3 hours of simulated driving, and 21 hours of practical training. For a C1 driver's license, you can schedule the Subject 2 test online 10 days after passing Subject 1. Each Subject 2 test appointment allows for two attempts. If the first attempt is unsuccessful, you can retake the test for free once. If you do not attend the retest or fail the retest, the test session ends, and you can reschedule Subject 2 after 10 days. Within the validity period of the driver's learning permit, the number of Subject 2 test appointments must not exceed five. If the fifth attempt is still unsuccessful, the results of other previously passed subjects will be invalidated. To continue pursuing the driver's license, you must restart the process from Subject 1. Subject 2 test content includes: driving a motor vehicle to complete test items within a designated area; demonstrating mastery of driving skills; and assessing the ability to judge the spatial position of the vehicle. Subject 2 is also known as the small road test and includes five mandatory items: reverse parking, parallel parking, hill start and stop, right-angle turns, and curve driving. Subject 2 test precautions: After getting into the car, always adjust the seat and mirrors to a suitable position and state, and ensure the seatbelt is fastened. For parallel parking, remember to find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. For hill starts, remember to engage the handbrake, activate the left turn signal when starting, release the handbrake, stabilize the clutch, and gradually release the clutch while pressing the accelerator to avoid stalling or rolling back. For right-angle turns, identify the turning point quickly and react accordingly, coordinating with the car's speed to prevent deviation. For curve driving (S-turns), slow down and proceed cautiously. Those with good driving instincts during practice may pass smoothly in one go. For reverse parking, control the speed carefully, identify reference points accurately, and make minor adjustments when observing deviations in the mirrors. The driver's license test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers traffic safety laws, regulations, and related knowledge. Subject 2 is the field driving skills test. Subject 3 is divided into two parts: road driving skills and safety and civilized driving knowledge. The safety and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official terminology (under the Ministry of Public Security's Order No. 123) does not include the term "Subject 4."

What's the reason for not being able to shift into S gear?

Failure to shift into S gear is mainly due to transmission damage. It is recommended to have it inspected and repaired at a 4S shop. Here are some related additional information: 1. S gear: S stands for 'sport'. In sport mode, the car's overall performance is enhanced, and its acceleration capability becomes stronger. Sport mode is often used for overtaking or climbing slopes. After engaging sport mode, the car's gear will drop quickly, with a certain delay in shifting, allowing the engine to maintain high RPMs for an extended period. 2. Possible fault points: It could be a fault in the clutch system's release bearing, friction disc, or pressure plate. It might also be an issue with the gear shift assembly or the shifting mechanism.
