Why Do Diesel Vehicles Emit Black Smoke?

Should the front axle rubber of the Sylphy be replaced with a rubber sleeve or the entire assembly?

The front axle rubber of the Sylphy needs to be replaced with the entire assembly because the front axle rubber sleeve and the front axle are integrated. The front axle is connected to the steering system via the steering knuckle, transmitting the steering force from the steering gear to the wheels to achieve vehicle steering. The components of the front axle are as follows: 1. Front axle: As the main component, the front axle is generally made of medium-carbon steel through die forging and heat treatment. Its cross-section is I-shaped or, to improve torsional strength, has a thickened section near each end shaped like a fist, with a through-hole where the kingpin is inserted. The middle part is bent downward into a concave shape to lower the engine position, thereby reducing the vehicle's center of gravity. 2. Steering knuckle: This is the hinge for wheel steering, shaped like a fork. The upper and lower forks have coaxial holes for installing the kingpin, and the steering knuckle spindle is used to mount the wheel. The ears on the steering knuckle's pin holes are connected to the fist-shaped parts at both ends of the front axle via the kingpin, allowing the front wheels to pivot around the kingpin for steering. 3. Kingpin: This connects the front axle and the steering knuckle, enabling the steering knuckle to swing around the kingpin for wheel steering. The middle of the kingpin has a groove; during installation, the kingpin fixing bolt aligns with this groove to secure the kingpin in the fist-shaped hole of the front axle. 4. Wheel hub: The wheel hub is supported on the spindle at the outer end of the steering knuckle via two tapered roller bearings. The bearing tightness can be adjusted with an adjustment nut (located at the outer end of the bearing). The outer end of the hub is covered with a pressed metal cap, and the inner end is equipped with an oil seal. The brake backing plate and dust cover are both fixed to the steering knuckle.

Can I Wear Makeup for the Subject 1 Test?

It is advisable not to wear heavy makeup during the Subject 1 test, and there are no specific requirements for clothing. The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" clearly stipulates that the Subject 1 test can be taken twice on the same day. If you fail the first attempt, you can take a second free retest. If you still fail the second attempt, the Subject 1 test will be terminated, and you can only reschedule the test after ten days. Subject 1, also known as the Subject 1 theory test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and other related knowledge. The Subject 1 test consists of 100 questions, divided into single-choice questions and true/false questions, with each question worth 1 point and a total score of 100. If you answer 11 questions incorrectly during the test, the system will automatically submit the test and end the exam. The Subject 1 test is computer-based and has a time limit of 45 minutes. Subject 1 test content: Driving license and motor vehicle management regulations; Road traffic conditions and regulations; Road traffic safety violations and penalties; Road traffic accident handling regulations; Basic knowledge of motor vehicles; Local regulations; Knowledge of braking systems and safety devices for large and medium-sized passenger and cargo vehicles; Special knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: During the test, candidates should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the examination room. Upon entering, check your assigned seat at the identity verification area and begin the test. Ensure the camera is aimed at you and follow exam discipline. If you fail the first attempt, you can retake the test on the same day. If you fail again, you will need to pay to reschedule. After the test, queue to collect your score sheet and sign it. Failure to sign will render the test invalid. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject can be taken once, and if you fail, you can retake it once. If you do not take the retest or fail the retest, the test will be terminated, and you must reschedule. In contrast, Subject 2 and Subject 3 only allow five attempts. Subject 2 and Subject 3 tests can be rescheduled after ten days. If you fail the Subject 3 safe driving knowledge test, your previously passed road driving skills test results remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; 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 the Ministry of Public Security Order No. 123) does not include Subject 4.

Can you make a U-turn on a yellow single dashed line?

A U-turn is allowed on a yellow single dashed line when there is no prohibition sign and it does not affect normal traffic flow. However, a U-turn is not permitted on a single solid line, as it constitutes a traffic violation. According to the "Road Traffic Safety Law," violators will be fined 200 yuan and receive 3 penalty points. On long roads, white or yellow solid or dashed lines are usually marked in the middle section or before intersections. U-turns are prohibited on any solid line. Scenarios where U-turns are allowed: Intersections with U-turn signs: If there is a clear U-turn sign at an intersection, a U-turn is permitted. If there is a U-turn traffic light, follow its instructions. In the absence of a traffic light, make a U-turn based on the situation, ensuring it does not obstruct other vehicles or pedestrians. Intersections without explicit no-U-turn or no-left-turn signs: If there is no clear prohibition, a U-turn is allowed. "No explicit prohibition" means the intersection lacks signs like "No U-turn," "No left turn," or a solid center line, in which case a U-turn is safe. Yellow grid lines also permit U-turns: Yellow grid lines indicate no-parking zones, typically at intersections prone to congestion or near important facilities. While parking on these lines is prohibited, U-turns are allowed unless there is a central barrier. Yellow grid lines without barriers are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn light, proceed only when it is green. When no-left-turn and U-turn-permitted signs coexist: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No left turn." Precautions when making a U-turn at an intersection: Check road markings: If the line is solid, a U-turn is prohibited under any circumstances. Continue driving to find a suitable spot. If there is a "No left turn" sign, even without a "No U-turn" sign, a U-turn is not allowed at that intersection, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, a U-turn is not permitted at that intersection. Always yield to oncoming traffic and ensure your U-turn does not disrupt the flow of straight-moving vehicles, or you will bear full responsibility for any accident. Near intersection stop lines, lanes often have guiding arrows. Not all leftmost lanes have left-turn arrows; some may have straight arrows. Even without explicit prohibitions, U-turns are not allowed in such lanes. U-turns on crosswalks are also prohibited and constitute a traffic violation.

Is it mandatory to install ETC?

It is not mandatory but encouraged for vehicle owners to install ETC. According to the State Council's regulations, vehicles without ETC installed by 2020 will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and vehicles can only pay tolls through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated first. During free holiday periods, vehicles with ETC can still use highways, and no fees will be deducted for ETC users passing through ETC lanes. The principle of ETC fee deduction: There will be one or more ETC lanes on highways. Through microwave-specific short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the purpose of vehicles not needing to stop at toll stations to pay road and bridge fees is achieved. All this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions, minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also explicitly set the goal in the main indicators of the "13th Five-Year" comprehensive transportation development: "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, efforts will be made to promote the use of ETC for trucks in the future. Exploration will be conducted for the deep integration of the ETC system with the development directions of smart transportation, such as vehicle-to-vehicle communication and vehicle-road coordination, to provide vehicle owners with comprehensive travel services. This means more application scenarios will support ETC applications.

Is it allowed to brush the line during reverse parking?

Brushing the line with the car body means the car body crosses the line, which results in a 100-point deduction and failure of the current test. Other actions that also lead to a 100-point deduction include the car body crossing the line, failing to enter the parking space, stopping midway, not following the prescribed route, not following the sequence, or exceeding the specified time. The full score for Subject 2 is 100 points, with evaluation criteria set for failure, 20-point deduction, 10-point deduction, and 5-point deduction. The rules for the Subject 2 driving test state that any of the following actions will result in failure: stopping or rolling back midway during the test, not following the voice prompts, or having the wheels or car body cross the line. Many learners encounter the issue of crossing the line during Subject 2 training, and the most common mistake leading to failure is "crossing the line." The main reason for crossing the line is that learners fail to master the correct timing for steering. Besides missing the right moment to steer, another reason could be that the steering speed does not match the car's speed. Subject 2 deduction criteria: Not wearing a seatbelt: 100-point deduction. Starting the engine without the gear in neutral: 100-point deduction. Not using the turn signal (including when starting, changing lanes, overtaking, turning, or parking); using the turn signal for less than three seconds (note that this is easily overlooked!); forgetting to turn off the turn signal or using it incorrectly: 10-point deduction. Stalling once: 10-point deduction. Reverse parking: Not following the prescribed route sequence: 100-point deduction. Car body crossing the line: 100-point deduction. Failing to complete the parking: 100-point deduction. Before reversing, if both front wheels do not pass the control line: 100-point deduction. Exceeding the 210-second time limit: 100-point deduction. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. Slope parking and starting: After stopping, if the car's front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: 100-point deduction. After stopping, if the car's front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: 10-point deduction. After stopping, if the starting time exceeds 30 seconds: 100-point deduction. Driving with wheels crossing the road edge line: 100-point deduction. Starting with the car rolling back more than 30 cm: 100-point deduction. After stopping, if the car body is more than 50 cm from the road edge line: 100-point deduction. After parking, not tightening the parking brake: 10-point deduction per occurrence. After stopping, if the car body is more than 30 cm but less than 50 cm from the road edge line: 10-point deduction per occurrence. Starting with the car rolling back more than 10 cm but less than 30 cm: 5-point deduction per occurrence. Parallel parking: After parking, if the car body crosses the line: 100-point deduction. Not using or incorrectly using the turn signal when parking: 10-point deduction. Exceeding the 90-second time limit: 100-point deduction. During driving, if the car body touches the parking space edge line: 10-point deduction per occurrence. During driving, if the wheels touch the lane edge line: 10-point deduction per occurrence. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. Right-angle turn: Wheels crossing the road edge line: 100-point deduction. Not using or incorrectly using the turn signal during the turn, or not turning off the turn signal after the turn: 10-point deduction. Stopping for more than 2 seconds midway: 5-point deduction per occurrence. Curve driving: Wheels crossing the road edge line: 100-point deduction. Stopping for more than 2 seconds midway: 100-point deduction. Driving without the gear in second or higher: 5-point deduction.
