Why is the Mercedes-Benz C200 engine noise loud?

What's the matter if the hood is open but stuck?

Car hood stuck may be due to damage to the front hood switch, or the front hood cable falling off or breaking. The following is relevant information: 1. Function: The hood is made of rubber foam and aluminum foil materials, which can reduce engine noise while isolating the heat generated during engine operation, effectively protecting the paint surface on the hood and preventing aging. 2. Principle: For objects moving at high speed in the air, the air resistance and turbulence generated by the airflow around the moving object will directly affect the trajectory and speed of movement. The shape of the hood can effectively adjust the direction of the air flow relative to the car's movement and the resistance force acting on the car, reducing the impact of airflow on the car. Through diversion, air resistance can be decomposed into beneficial forces, increasing the force of the front tires on the ground, which is beneficial to the stability of the car. The streamlined appearance of the hood is basically based on this principle.

If the right turn arrow is red and I didn't notice when turning right, will I be caught by the camera?

In general cases, running a red light will be captured by electronic monitoring systems. Below is relevant information: 1. Definition criteria: Running a red light requires three photos as evidence - the vehicle crossing the stop line, the vehicle moving to the middle of the intersection, and the vehicle reaching the opposite side of the intersection. Only when all three photos are captured will it be considered as running a red light. 2. General situation: According to current red-light running detection technology, the system's vehicle capture rate is 100%, recognition time is about 1 second, daytime recognition rate exceeds 95%, and nighttime recognition rate exceeds 90%. Therefore, in most cases, running a red light will be captured by electronic monitoring. 3. Special circumstances: When photos show no red light, incomplete license plate numbers, or two license plates appearing in the same photo, these are considered invalid captures. However, the probability of such situations occurring is extremely low.

What is the Engine Oil Viscosity Grade Chart?

The viscosity grade of engine oil is closely related to the vehicle model and local temperature, indicating the ambient temperature. Below is an introduction to vehicle models and grades: 1. Vehicle models: Japanese cars primarily use low-viscosity oil, while German cars primarily use high-viscosity oil. 2. Grades: (1) 0W suitable temperature: -35°C (polar regions). (2) 5W suitable temperature: -30°C (northeast and northwest regions). (3) 10W suitable temperature: -25°C (north-central and southwest regions). (4) 15W suitable temperature: -20°C (north-central and southwest regions). (5) 20W suitable temperature: -15°C (areas south of the Yellow River and north of the Yangtze River). (6) 25W suitable temperature: -10°C (subtropical regions).

Where is the OBD port on Dongfeng Fengguang?

The OBD interface of Dongfeng Fengguang is located behind the glove box on the passenger side. You can see the interface by removing the glove box. The OBD port of a car mainly has four functions: 1. Display of engine control unit data: The OBD port can provide various operational data of the vehicle, such as data displayed on the vehicle dashboard, fuel consumption records, battery voltage, air-fuel ratio, throttle opening, knock count, etc.; 2. Reading fault codes: The OBD port can be used to read fault codes, which helps in quickly diagnosing vehicle faults and reducing manual diagnosis time; 3. Changing codes to achieve more functions: By connecting the vehicle's CAN bus through the OBD port's data cable and adjusting the codes of various modules, many different 'hidden' functions can be achieved, enabling 'additional configurations'; 4. Reading and flashing ECU and TCU programs: This allows manufacturers to update the ECU control program at any time, but it is not recommended to modify it yourself.

How long must the interval be between driving test subject 1 and subject 2?

For a C-class driver's license, you can schedule the subject 2 test online 10 days after passing subject 1, while for B-class and A-class licenses, you must wait 20 days. Each subject 2 test appointment allows for two attempts. If you fail the first attempt, you can retake it once for free. If you do not take the retest or fail the retest, the test session ends, and you can reschedule the subject 2 test after 10 days. Within the validity period of the driver's license learning permit, the number of subject 2 test appointments must not exceed five. If you fail the fifth attempt, all previously passed subjects will be invalidated. To continue learning for the driver's license, you must restart from subject 1. Article 33 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulates the content of the subject 2 test: For large buses, heavy-duty trailers, city buses, medium-sized buses, and large trucks: yard test, hill start, parallel parking, single-plank bridge, curve driving, right-angle turn, narrow gate, U-turn on narrow roads, and simulated highway driving, continuous sharp mountain roads, tunnels, rain (fog) conditions, slippery roads, and emergency handling. For small cars and low-speed trucks: reverse parking, hill start, parallel parking, curve driving, and right-angle turn. For small automatic transmission cars and small automatic transmission cars for the disabled: reverse parking, parallel parking, curve driving, and right-angle turn. Some regions also include a sixth item: highway toll card collection. For light trailers: yard test, curve driving, and right-angle turn. For three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, and light motorcycles: yard test, hill start, and single-plank bridge. The test content for wheeled special machinery, trolleybuses, and trams is determined by the provincial traffic management department of the public security authority. For the vehicle types specified in items 1 to 3 of the first paragraph, the provincial traffic management department of the public security authority may add test content based on actual conditions. Subject 2 test precautions: After getting in the car, adjust the seat and mirrors to a suitable position and state, and always fasten your seatbelt. For parallel parking, find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. For hill starts, remember to pull the handbrake, turn on 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, find the correct point and turn quickly, coordinating with the car's speed to avoid deviation. For curve driving (S-turn), slow down and proceed cautiously. Those with good driving skills during practice can pass quickly in one go. For reverse parking, control the speed, identify reference points, and make minor adjustments if deviations are observed in the mirrors. The driving test consists of three subjects: subject 1, subject 2, and subject 3. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after subject 3, so it is commonly referred to as subject 4. However, the official term (as per Public Security Ministry Order No. 123) does not include "subject 4."
