The ring inside the tire is called the wheel hub, also known as the rim or steel ring. It is a cylindrical metal component used to support the tire and is an important part of automotive components. When driving, special attention should be paid to the maintenance of the wheel hub, as it is prone to accumulating dirt. If not cleaned for a long time, it may corrode and deform, potentially leading to safety hazards. In the market, wheel hubs can be categorized into steel wheel hubs and alloy wheel hubs based on material. The main advantages of steel wheel hubs are their simple manufacturing process, relatively low cost, and strong resistance to metal fatigue. Alloy wheel hubs are lighter in weight, have lower inertial resistance, higher manufacturing precision, and less deformation during high-speed rotation. They also help improve the car's straight-line driving performance, reduce tire rolling resistance, and consequently decrease fuel consumption.

What does das-auto mean?

das-auto means that Volkswagen represents automobiles. Volkswagen is a German automobile manufacturing company headquartered in Wolfsburg, Germany, and is the core enterprise of the Volkswagen Group, one of the world's four largest automobile manufacturers. The Volkswagen brand portfolio includes eight brands: Volkswagen Commercial Vehicles, Volkswagen Passenger Cars, SKODA, Bentley, Bugatti, Porsche, SCANIA, and MAN. Additional information: 1. General explanation: Overall, volkswagen is the trademark of Volkswagen, while das-auto is just an advertising slogan. In German, volkswagen means 'the people's car,' and das-auto directly translates to 'the car' in English. 'das' is a neutral article indicating that the following noun is inanimate or of undetermined gender; 'auto' means 'car' in German. The Chinese translation of Das-Auto is 'The Way of Cars, Only Volkswagen.' 2. From a German language perspective: Additionally, Das-Auto is German, where 'das' is merely a prefix indicating grammatical gender without actual meaning. In German, nouns have gender prefixes indicating masculine, neuter, or feminine. 'auto' means 'car' in German, so Das-Auto essentially means 'the car' in Chinese. Translated into English, Das-Auto is 'The-Auto,' which can roughly be understood as 'This is the car.'

Is Porsche Manual or Automatic Transmission?

Porsche Macan is equipped with an automatic transmission. The Porsche Macan utilizes the chassis of the Audi Q5. Whether it's the 2.0T-L4, 3.0T-V6, or 3.6T-V6, all models are fitted with a 7-speed dual-clutch transmission. The 7-speed dual-clutch DSG differs from conventional semi-automatic transmission systems; it is based on a manual transmission rather than an automatic one, thus also classifying it as an AMT (Automated Manual Transmission). Below are common transmission faults: Oil leakage: Oil seeping from the transmission casing or oil pan can be caused by aging seals leading to poor sealing or manufacturing defects resulting in porous casings. Engine stalling when engaging gear: Stalling upon shifting into D or R may be due to a faulty lock-up solenoid valve or a stuck lock-up control valve. Locked gear: Incorrect input/output signals from the transmission or issues with components and their circuits can cause this, sometimes also arising from communication problems between the transmission computer and other system computers. No response when engaging gear: The vehicle doesn't move after shifting into D or R and releasing the brake, often due to damage to the input shaft or reverse clutch, or failure of the D/R brake. Abnormal noises: Unusual sounds from the transmission area during driving are typically caused by worn parts or improper installation of the transmission.

What does engine start-stop technology mean?

Introduction to the meaning of engine start-stop technology: Engine start-stop technology refers to the automatic shutdown of the engine when the vehicle comes to a temporary stop during driving (e.g., at a red light). When it's time to move forward again, the system automatically restarts the engine. Here are more details: 1. The working principle of the start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensors of the anti-lock system show zero; the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops. 2. The operation of the automatic start-stop system is as follows: while driving, as soon as the brake pedal is pressed directly and the vehicle comes to a complete stop for about two seconds, the engine will automatically shut off. As long as the brake pedal is held down, the engine remains off. As soon as the brake is released or the steering wheel is turned, the engine automatically restarts immediately, allowing the driver to press the accelerator and start moving again, all while remaining in D gear.

How Long Does the Driving School Learning Period Expire?

According to Article 38 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the learning driving permit obtained during the process of learning to drive on training grounds and roads will expire after three years. The validity period of the learning driving permit is three years, and applicants must complete the subject two and subject three tests within this period. Failing to complete the tests within the validity period will result in the invalidation of any previously passed subjects. The passing standards for the driving license test are as follows: 1. Traffic regulations and related knowledge (Subject One) written test, with a full score of 100, and a passing score of 90 or above (including 90). 2. Field driving (Subject Two) on-site, actual vehicle operation. Only pass or fail is assessed. There are nine mandatory test items (all without poles), including reversing into a garage, turning around on a narrow road, parallel parking, stopping and starting on a slope, turning at a right angle, driving on a curve, emergency braking, driving through a tunnel, and taking a card at a toll booth. All nine items must be passed to pass the Subject Two test. 3. Road driving (Subject Three) on the highway or simulated site, actual vehicle operation. The test is fully monitored by electronic eyes and traffic police, making the road test more fair.

What are the symptoms of abnormal intake manifold vacuum?

Symptoms of abnormal intake manifold vacuum are as follows: 1. It can cause weak engine operation. 2. It may lead to difficulty in engine starting. 3. It can affect emissions. 4. It may result in unstable idle. The effects of intake manifold air leakage on the engine mainly include the following aspects: 1. Abnormal intake manifold vacuum can cause weak engine operation: If the intake manifold vacuum is too low at idle, it indicates that air is entering the intake manifold through bypass routes. Since this air is not measured by the mass air flow sensor or controlled by the throttle, the sensor's reading will be lower than the actual intake air volume. The ECU determines the basic fuel injection quantity based on signals from the mass air flow sensor, leading to insufficient fuel injection and an overly lean air-fuel mixture, resulting in weak engine operation. 2. Abnormal intake manifold vacuum can cause difficulty in engine starting: If the circular cover at the end of the intake manifold's upper stabilizer chamber falls off, excessive air intake will make the air-fuel mixture too lean, causing difficulty in engine starting. 3. Abnormal intake manifold vacuum can affect emissions: Reduced intake manifold vacuum increases engine load and combustion chamber temperature, raising the peak temperature of exhaust gases per cycle, which leads to higher NOx emissions. 4. Abnormal intake manifold vacuum can cause unstable idle: If there is an intake manifold air leak, the mass air flow sensor cannot accurately measure the real intake air volume, causing the ECU to inaccurately control the air intake, resulting in unstable engine idle.
