Automobile maintenance should adhere to the principle of prevention first, abandoning the concept of repairing instead of maintaining. Maintenance means keeping and caring, maintaining the vehicle in good working condition through good usage habits. Caring involves keeping the vehicle in good working condition through operations such as inspection, adjustment, tightening, lubrication, and replacement. The related introduction is as follows: 1. Purpose of maintenance: The purpose of automobile maintenance is to keep the vehicle clean and tidy, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life. Modern automobile maintenance mainly includes the maintenance of the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 2. Daily maintenance: Daily maintenance, also known as daily upkeep, is the work done before driving, during driving, and after parking, which is the responsibility of the driver. The main content of the work is cleaning, replenishment, and safety inspection, which are regular and necessary tasks to keep the vehicle in normal working condition. Primary maintenance is performed by professional maintenance enterprises. In addition to daily maintenance tasks, the main content of the work is cleaning, lubrication, and tightening, as well as inspecting safety components such as brakes and controls. Secondary maintenance is performed by professional maintenance enterprises. In addition to primary maintenance tasks, the main content of the work is inspection and adjustment, as well as dismantling and inspecting tires for tire rotation. Before secondary maintenance, diagnostic testing and technical evaluation should be conducted to determine additional tasks or minor repairs based on the results, which are carried out together with the secondary maintenance. The maintenance cycle for each level depends on the type of vehicle and operating conditions.

Is CVT Continuously Variable Transmission an Automatic Transmission?

CVT continuously variable transmission comes in both automatic and manual versions. CVT technology, or continuously variable transmission technology, uses a drive belt and variable-diameter primary and secondary pulleys to transmit power, allowing for continuous changes in the transmission ratio. This achieves the best match between the transmission system and the engine's operating conditions. Advantages and disadvantages of CVT continuously variable transmission: 1. Advantages: (1) Since there are no transmission gears like in a conventional automatic transmission, the gear-shifting jerkiness is eliminated, resulting in a very smooth driving experience. (2) Gear settings are more flexible, making it easier to achieve the balance between gear ratios, speed ratios, performance, fuel consumption, and exhaust emissions in traditional transmission systems. (3) The mechanical efficiency and fuel economy of CVT transmission are significantly better than those of conventional automatic transmissions. 2. Disadvantages: (1) Compared to traditional automatic transmissions, maintenance costs are higher, and the probability of issues is greater if operated improperly. (2) CVT transmissions have limited torque capacity and are only suitable for small cars with engine displacements ranging from about 1 liter to 1.5 liters.

1. Golden Mobil 1 is essentially Mobil 1, with the distinction lying in different viscosity levels. The manufacturer separates the packaging to facilitate consumer differentiation. 2. Mobil 1 is a high-performance oil capable of operating under the most demanding conditions while effectively protecting the engine. Additional Information: Features and Benefits: 1. Contains active cleaning agents to prevent carbon deposits and sludge buildup, keeping the engine clean over the long term and extending its lifespan. 2. Thermal and oxidation stability delays lubricant aging, extending oil change intervals. 3. Low oil consumption reduces hydrocarbon pollution. 4. Friction characteristics enhance fuel efficiency.

Why Can't Eagle Flag Engine Oil Be Purchased Online?

Different industries have different marketing channels, so some engine oils cannot be purchased online. Here is a partial introduction to engine oil: 1. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives are an important part of the lubricating oil. 2. Types of engine oil: The winter oil grades classified by SAE lubricant viscosity are 0W, 5W, 10W, 15W, etc. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity and the lower the applicable minimum temperature. The summer oil grades classified by SAE lubricant viscosity are 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature.

The maximum power speed of this engine is 5800 rpm, and the maximum torque speed is 1350 to 4500 rpm.

What are the test items for the C2 Subject 2 exam?

The C2 Subject 2 exam consists of 4 test items: reversing into a garage, parallel parking, curve driving, and right-angle turns. In some regions, there is also an additional item for highway toll card collection. Compared to the C1 manual transmission exam, the C2 exam does not include the hill start item. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" (Ministry of Public Security Order No. 123), starting from June 1, 2021, the C2 and C5 Subject 2 exams no longer assess the hill start and stop item. Reversing into a garage is one of the more challenging items in the Subject 2 exam, so many test centers have made it the first test item in Subject 2. The requirement is to follow the designated route and sequence, ensuring the vehicle is fully reversed into the garage without crossing lines, brushing lines, or stalling. Students should slow down, observe the left and right rearview mirrors carefully before fully entering the garage, identify the correct entry points, and make decisive adjustments to the vehicle's position. Parallel parking focuses on aligning the front line of the parking space with the rear wheel reference point, observing the rear corner in the mirror, and maintaining the distance between the wheel and the left dashed line. After parking, there is no need to straighten the wheels, but do not forget to use the turn signal when exiting. The vehicle body must not exceed the lines when stopped, and the tires must not touch or cross the lane boundary lines during movement. Curve driving, commonly known as the S-curve, is manageable for many students with good driving intuition, who can complete it "by feel," indicating its relatively low difficulty. However, some students misjudge the line positions during the actual exam, leading to immediate failure by crossing the lines. The key to the S-curve is observing the reference points on the front hood and the boundary lines. The wheels must not press against the road edges. Right-angle turns are even simpler, essentially a breakdown of the exiting step from the reversing into a garage item. The method for finding the reference points is the same as for exiting—using the relationship between the front hood's horizontal line and the front boundary line (either aligning exactly or slightly delaying). Ensure the wheels do not touch the road edges. Completing the required training hours is a basic requirement for taking the Subject 2 exam. Training hours can only be increased, not reduced. If additional test items are added, corresponding training hours must also be increased. Each training hour is 60 minutes, with effective teaching time no less than 45 minutes. If a student fails the Subject 2 exam, they can retake it once. If they fail the retake, the exam session ends, and the applicant must reschedule the exam after 10 days. If the student fails five consecutive exam attempts (including retakes, totaling 10 attempts), all previously passed subject scores will be voided, and the student must restart from Subject 1.

Is the C2 Subject 2 Test Easy to Pass?

C1 or C2 Subject 2 tests are basically the same in difficulty, including reverse parking, parallel parking, right-angle turns, curve driving, and in some areas, a fifth item of high-speed toll card collection. The passing score for the C2 Subject 2 test is 80 points. For some vehicle types, a score of 90 is required to pass. These vehicle types include large buses, tractors, city buses, medium-sized buses, and large trucks. For these vehicle types, a score of 90 is needed in Subject 2. Other vehicle types only require 80 points to pass, and since C2 is for automatic transmission cars, 80 points are sufficient. During the test, paying attention to small details and avoiding more than two minor point deductions can help you pass smoothly. Each Subject 2 test has two attempts. If you fail the first time, there is a free retake opportunity on the spot. About 30% pass on the first try, and with those who pass on the retake, the overall pass rate is around 60%. Both Subject 2 and Subject 3 have only five test attempts. If you fail the fifth test, all previously passed subjects will be invalidated, and you will need to retake the driving test.
