Is an ignition advance angle of 12 degrees or 9 degrees better?

An ignition advance angle of 9 degrees is better, for the following reasons: The ignition advance angle is generally between 6 and 12 degrees. A 12-degree ignition advance angle is too large compared to 9 degrees, which can lead to delayed ignition. If ignition is delayed, the gas will have difficulty performing work, fuel consumption will increase, efficiency will decrease, and exhaust noise will also increase, affecting the engine's working efficiency. Additional information: Ignition advance refers to the spark plug firing before the engine piston reaches the top dead center of compression. The angle through which the crankshaft rotates from the moment the spark plug fires until the piston reaches the top dead center of compression is called the ignition advance angle.

How Many Questions Are There in Subject 4 Exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," Subject 4 consists of 50 questions, each worth 2 points, totaling 100 points. Questions 1-10 are true/false; questions 11-40 are single-choice; and questions 41-50 are multiple-choice. The exam includes question types such as image analysis, animated case studies, and textual descriptions. The scope of Subject 4 covers driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and hand signals; accident rescue and hazardous material handling knowledge; comprehensive judgment of violations and case analysis; emergency avoidance knowledge; safe driving knowledge; and driving ethics and civilized driving knowledge. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," there is no limit to the number of attempts for Subject 1 and Subject 4 exams. If the first attempt on the same day is unsuccessful, a retake can be conducted immediately. If it still fails, a new appointment is required, and no retake fee is charged. However, it should be noted that the validity period of the driving skill test permit is three years. If the applicant fails to complete the exam within the validity period, the passed subject scores will be invalidated. Subject 4, also known as the Subject 4 theory exam or driver theory exam, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and the addition of a safety and civilization knowledge exam, commonly referred to as "Subject 4." Subject 4 is the colloquial term for the Subject 3 safety and civilized driving knowledge exam and is not a separate subject. Since this exam is conducted after Subject 3, it is commonly referred to as the Subject 4 exam. Officially, there is no Subject 4. The safety and civilized driving knowledge exam is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 30 minutes, and incorrect answers totaling 12 points (6 questions) will terminate the exam. Number of Questions: Depending on the type of license being tested, 50 questions are proportionally selected from the corresponding Subject 4 question bank. Small vehicle licenses draw from 800 questions, while large vehicle licenses draw from 1,023 questions, with each question worth 2 points. Question Types: The questions include single-choice (including true/false) and multiple-choice. The first 45 questions are single-choice, and the last 5 are multiple-choice. The exam also includes animated questions, image-based questions, scenario recognition questions, and textual description questions. Retake Notes: If Subject 4 is not passed, only Subject 4 needs to be retaken. The driving school will schedule the retake, with no limit on the number of retakes. No retake fee is required for Subject 4. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills exam; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge exam.

Under What Circumstances Should the Transmission Fluid of the New Santana Be Replaced?

The transmission fluid of the New Santana should be replaced when it becomes viscous, turns black, or emits an unusual odor. Relevant knowledge about the New Santana's transmission fluid is as follows: Automatic Transmission Fluid: The New Santana uses an automatic transmission. The automatic transmission fluid has two main functions: transmitting hydraulic power and cleaning/lubricating. The original color of the automatic transmission fluid is red and transparent. Replacement Considerations: The recommended amount of transmission fluid for the Volkswagen New Santana is approximately 2 liters. When replacing the fluid, it is essential to use the automatic transmission fluid specified by the manufacturer. This is because different automatic transmissions have varying internal structures, friction components, and sealing components. The original fluid is specially formulated based on the transmission's structure and materials. Even if other brands of fluid are of high quality, they may not be suitable.

Can You Still Drive with Low Tire Pressure Display?

When the tire pressure is too low, it is recommended to find a safe place to stop slowly, then place a warning sign 150 meters away from the vehicle, and finally call the insurance company for assistance. Driving for a long time with low tire pressure can cause significant damage to the tires and, in severe cases, endanger the safety of the driver and passengers. It is best not to let the tire pressure fall below the manufacturer's recommended value, which is generally between 2.2 and 2.5. Below are the hazards of low tire pressure: 1. The tire's self-friction coefficient increases, the tread on the ground becomes flatter, and the non-ground tread loses its normal shape, leading to an abnormal movement cycle that raises tire temperature; 2. Low tire pressure increases tire deformation, making the sidewalls prone to cracks and causing flexing movements, which generate excessive heat, accelerating rubber aging, cord fatigue, and cord breakage, while also increasing the tire's contact area and accelerating deformation; 3. Additionally, low tire pressure can lead to increased fuel consumption, a heavy steering wheel, and a tendency for the vehicle to pull to one side.

How to Align Points for the S-Turn in Subject 2?

Subject 2 S-turn generally has 5 alignment points. The specific alignment methods are as follows: 1. After entering the curve, carefully observe the position of the engine hood relative to the road edge line. When the engine hood aligns with the right edge line, turn the steering wheel one full turn to the left; 2. Keep the vehicle moving forward. When the left front of the car overlaps with the right edge line, turn the steering wheel half a turn to the left, maintaining the overlap between the car front and the edge line; 3. When preparing to turn right, straighten the steering wheel when the left front of the car aligns with the left edge line; 4. Continue driving. When one-third of the left engine hood aligns with the edge line, turn the steering wheel one full turn to the right; 5. When the right front of the car overlaps with the left edge line, turn the steering wheel half a turn to the right, then maintain the overlap between the car front and the left edge line.
