What Causes the Left-Right Shaking of a Mercedes-Benz at Idle?

Mercedes-Benz left-right shaking at idle can be attributed to the following reasons: Engine Mount Issues: For instance, if the engine mounts are too dirty, aged, or damaged, they can cause engine vibrations that transmit throughout the entire vehicle body. Resonance at Idle: For example, some cars may shake when the idle speed is stable at 700 RPM. In such cases, simply increasing the idle speed slightly can stop the shaking. Therefore, if all else fails, you can try adjusting the idle speed in D gear. Air-Fuel Mixture Problems: Among these, excessive carbon buildup in the throttle body and fuel injectors is the most common cause of shaking. On one hand, carbon deposits tend to absorb fuel vapor, leading to a leaner air-fuel mixture. Once the carbon deposits absorb enough fuel vapor, the car returns to normal operation. This is one reason why the car shakes when cold but stops shaking once it warms up. On the other hand, carbon deposits can cause blockages, such as clogging the fuel injectors, reducing the amount of air-fuel mixture entering the cylinders or causing poor atomization, which can also lead to shaking.

What Causes Jerking in Automatic Transmission Cars?

Common causes of jerking in automatic transmission cars are as follows: Engine Power Supply System: Spark plugs and ignition coils: If high-voltage sparking is poor, it can lead to intermittent engine malfunction. Engine Fuel Supply System: Fuel injectors: If the fuel injectors have carbon deposits, minor blockages, or poor atomization, it can easily cause irregular fuel injection. Transmission Issues: If the transmission experiences impacts, jerking, or gear slipping, it is usually due to a damaged valve body or dirty transmission fluid with internal impurities. Especially when dirt and impurities accumulate and block the passages inside the valve body, it can prevent effective regulation of oil pressure, leading to jerking, impact, or slipping. Damaged Engine Mounts: Damaged engine mounts or transmission mounts fail to provide cushioning when releasing the throttle, resulting in jerking. Excessive Carbon Deposits in the Throttle Body: If the throttle body is not cleaned for a long time, excessive carbon deposits can alter the throttle opening angle, causing jerking when releasing the throttle.

What does driver's license clock-in mean?

When obtaining a driver's license, clock-in refers to the "time-recording system" implemented in driver's license tests. Upon registration for the driving test, students receive a card from the driving school. During in-car practice sessions, the instructor will have students insert this card into the vehicle's onboard device to start accumulating training hours. Only after completing the required hours can students take the relevant subject tests. Below are clock-in precautions: 1. Daily clock-in is limited to 2 hours: Excess time won't be accumulated. 2. No proxy clock-ins allowed: A camera installed in the vehicle facing the driver's seat will record the process, which is automatically uploaded to the DMV for verification. Any single clock-in session shorter than 20 minutes (within the daily 2-hour limit, multiple sessions are allowed but each must be at least 20 minutes) or if the clock-in is done by someone else will be considered invalid. 3. Start clock-in before 12 noon: If the session spans the 12-1 PM period, do not remove the card. Otherwise, the time will be invalid. For example, if clock-in starts at 11:59 AM, the card must remain inserted until after 1 PM. Removing it midway will void that clock-in session.

What Causes the Smell of Burning While Driving?

During vehicle operation, oil stains may accumulate on various channels and pipelines of the engine and transmission due to various reasons. When exposed to high temperatures while driving, these stains can emit a burning smell, which is harmless to the vehicle and will dissipate on its own after a short time. Plastic Bag Stuck to the Exhaust Pipe: If the burning smell is coming from your own vehicle, it might be caused by a plastic bag stuck to the exhaust pipe. Thin plastic bags on the road can be lifted by the wind as the car passes and adhere to the hot exhaust pipe, where they melt and produce a burning plastic odor. Although the smell originates from the underside of the vehicle, once the plastic melts, the odor spreads around the car and can enter the cabin through the air intake, making it noticeable inside. In such cases, simply stop the car, inspect, and remove the plastic bag. Forgetting to Release the Handbrake: If you forget to release the handbrake before driving, continuing to drive can also produce a burning smell. With the handbrake engaged, the brake pads remain in constant friction during driving, generating significant heat that can burn the pads and create a burning odor. This situation is more common in automatic transmission vehicles and typically occurs with novice drivers, though the probability of it happening is relatively low.

What is the fuel tank capacity of the BMW 3 Series GT in liters?

The fuel tank capacity of the BMW 3 Series GT-2020 320i M Sport Night Edition is 60L. It is equipped with a 2.0L turbocharged engine and an 8-speed automatic transmission (AT). The drivetrain is front-engine, rear-wheel drive. The front suspension features a double-joint spring strut, while the rear suspension is a multi-link independent suspension. In the same vehicle class, the Audi A4 (imported)-2022 Avant 40 TFSI Fashion Elegance model has a fuel tank capacity of 54L, and the Mercedes-Benz C-Class (imported)-2022 facelifted C200 Coupe has a fuel tank capacity of 66L. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the manufacturer is measured from the bottom of the tank to the safe fill level, and there is additional space from the safe fill level to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the marked capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, marked with E (Empty) and F (Full). When the needle approaches E, it indicates low fuel, while nearing F means the tank is sufficiently full.

Can a novice driver drive on the highway, and what are the penalties for novice drivers on the highway?

Novice drivers can drive on the highway but must be accompanied by an experienced driver with more than three years of driving experience. The penalties for driving on the highway during the probationary period are as follows: 1. A fine of 200 yuan for driving alone on the highway: The probationary period for first-time applicants of a motor vehicle driver's license and those who have added a new vehicle category is 12 months (i.e., 12 months from the 'initial license date' on the driver's license). If the probationary period is extended, it will be 24 months from the 'initial license date.' Drivers in the probationary period must be accompanied by a driver holding a corresponding or higher-level driver's license for more than three years when driving on the highway. The accompanying driver should sit in the front passenger seat to guide the novice driver. If there is no accompanying driver or the accompanying driver does not meet the requirements, a fine of 200 yuan will be imposed. 2. A fine of 200 yuan for not displaying the 'probationary sign': During the probationary period, drivers must display a standardized probationary sign on the rear of the vehicle. Traffic police remind that if a probationary driver does not display or hang the standardized sign on the rear of the vehicle; if the sign cannot be properly identified; or if the sign does not meet the requirements, such as 'new driver on the road' or self-printed signs, it will be considered as not displaying the sign, and a fine of 200 yuan will be imposed.
