What is Ignition Advance Angle?

Ignition advance angle refers to the angle through which the crankshaft rotates from the moment of ignition until the piston reaches the top dead center of compression. The functions of ignition advance angle are: 1. To ensure the effective utilization of the energy generated by the combustible mixture; 2. To improve the engine's output power. The adjustment method for ignition advance angle is: 1. Check whether the platinum contacts have signs of burning; 2. Remove the secondary chamber vacuum hose from the vacuum advance compensation device, block the two ports connected to the hose, and let the engine idle; 3. Use an ignition timing light to check the ignition advance angle; 4. When rotating the distributor housing counterclockwise, the ignition advance angle will increase; 5. When rotating the distributor housing clockwise, the ignition advance angle will decrease.

What type of engine oil is recommended for the Geely Borui 1.8T?

For the Geely Borui 1.8T model, it is recommended to use fully synthetic engine oil. The relevant details are as follows: 1. Since the vehicle's engine is equipped with a turbocharger, the engine operates under high temperature and high-speed conditions when the turbocharger is working, thus requiring higher lubrication performance from the engine oil. 2. Fully synthetic engine oil provides excellent lubrication, which can extend the engine's service life. Additional information is as follows: 1. Fully synthetic engine oil is a high-grade product among engine oils. It is derived from ethylene and propylene dispersed from natural gas or crude oil gas, which then undergo polymerization, catalysis, and other complex chemical reactions to form a lubricating fluid composed of large molecules. 2. Essentially, it utilizes the superior components of crude oil, subjected to chemical reactions and controlled human intervention to achieve the desired molecular structure. 3. The molecules in fully synthetic oil are neatly arranged, giving it strong resistance to external changes. Therefore, it has superior properties, such as better thermal stability, oxidation resistance, and viscosity stability compared to mineral and semi-synthetic oils, which is why it is more expensive.

What does Mercedes-Benz's 4matic mean?

Mercedes-Benz's 4Matic is a full-time four-wheel drive system, with its core technology being the 4ETS differential limiting technology. 4ETS utilizes the automatic braking force distribution function of ABS to achieve differential limiting. Development of Mercedes-Benz 4Matic all-wheel drive system: The first-generation 4MATIC used lockable center and rear axle differentials. The center differential contained two sets of clutches, with each electronically controlled clutch operating independently to achieve various drive modes. The current Mercedes 4MATIC system employs open differentials at the front, center, and rear. The center/rear differentials feature a lockable multi-plate clutch structure, functionally serving the role of traditional differential locks. With the assistance of four-channel ABS, torque can be distributed to each wheel, maximizing driving safety and enabling strong off-road capabilities. Characteristics of Mercedes 4Matic all-wheel drive system: The 4Matic system is designed to be compact and lightweight while delivering optimized friction performance, showing significant advantages compared to other all-wheel drive systems. It also offers improvements in weight, fuel economy, comfort, and passive safety.

Is an automatic transmission C1 or C2?

An automatic transmission is classified as C2. The permitted vehicle types for C2 include small and micro automatic transmission passenger vehicles, as well as light and micro automatic transmission cargo vehicles. It only allows driving automatic transmission cars with fewer than 9 seats and a length not exceeding 6 meters. Automatic transmission vehicles do not have a clutch pedal and do not require gear shifting, making them easier to operate and eliminating concerns about stalling. More relevant information is as follows: 1. C1 is for manual transmissions, with permitted vehicle types including small and micro passenger vehicles, light and micro cargo vehicles, light, small, and micro special operation vehicles, and small passenger vehicles (with seating capacity less than or equal to 9 people). 2. A C1 license does not permit driving large buses, tractors, city buses, medium-sized buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, mopeds, wheeled self-propelled machinery, trolleybuses, or trams.

What is Tested in Driving License Exam Subject 4?

The content of Subject 4 exam includes: safety and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, knowledge on preventing secondary accidents, and first aid knowledge for the injured. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the Subject 4 exam consists of 50 questions, primarily in the form of case studies, pictures, animations, etc. The exam is scored out of 100, with a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and an additional safety and civilized driving knowledge test, commonly referred to as Subject 4. This is not a separate subject but is called Subject 4 because it is conducted after Subject 3. Officially, there is no Subject 4. The safety and civilized driving knowledge test is conducted after Subject 3. Subject 4 has no limit on the number of attempts. If you fail the first attempt on the same day, you can retake it immediately. If you still fail, you need to reschedule the exam, but no additional fees are required for retakes. However, it is important to note that the validity period of the driving skill permit is three years. If the applicant fails to complete the exam within this period, the results of any previously passed subjects will be invalidated. Subject 4 Exam Notes: Exam Duration: The exam lasts 45 minutes. If you make 10 mistakes (5 questions) during the test, the exam will be terminated. Number of Questions: Depending on the type of driving license, 50 questions are selected proportionally from the Subject 4 question bank, with each question worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions. The questions may involve animations, pictures, scenario recognition, or text descriptions. Retake Notes: If you fail Subject 4, you only need to retake Subject 4. The driving school will schedule the retake, and there is no limit to the number of retakes. You can retake it until you pass, and no additional fees are required for retakes. Subject 4 Exam Tips: Strengthen weak areas and identify the reasons for mistakes. For marked questions, do not just memorize the correct answer. Refer to regulations, textbooks, or reference materials to understand the reasons behind the mistakes and internalize them. Categorize and summarize questions. Refer to the question bank analysis for classification and find similar questions. Many questions in the bank are similar and can be confusing, so it's helpful to group them for analysis. For example, traffic signs like "pedestrian," "walking," "beware of pedestrians," "crosswalk," and "beware of crosswalk" have similar patterns and can be confusing. Grouping them during study helps avoid mistakes. Use memory techniques: Many questions in the bank involve numbers. Summarizing these numbers can make memorization easier.
