How Many Kilometers Can 4 Liters of Oil Run?

4 liters of oil can generally run for about 50 kilometers. Mineral Oil: Mineral oil base is refined from crude oil. After extracting gases, gasoline, diesel, kerosene, and heavy oil from crude oil, the mineral oil base is then refined, leaving asphalt as the final residue. The mineral oil base is transparent with a slight amber tint, similar to the color of salad oil. Typically, mineral oil is very low-cost, but since the mineral oil base oxidizes more easily, even though modern mineral oils contain various imported additives, their service life is still about six months. Full Synthetic Oil: Full synthetic oil contains only PAO or ester-based synthetic compounds, all of which are artificially made through chemical processes. Initially used in the aviation industry, it was later adopted in racing and is now widely used in passenger cars. The advantages of full synthetic oil include high cleanliness, excellent fluidity, superior cooling capability, and outstanding oxidation resistance. Semi-Synthetic Oil: Semi-synthetic oil is a blend of synthetic oil with a portion of mineral oil, typically in a ratio of 4:6 (mineral oil to synthetic oil). It combines the benefits of full synthetic oil while being more affordable. However, semi-synthetic oil performs slightly worse than full synthetic oil in all aspects, with the main advantage being its lower price. Its replacement cycle is also slightly shorter than that of full synthetic oil.

How should the compulsory traffic insurance cost for vehicles be calculated?

The cost of compulsory traffic insurance can vary (except for the first year), and the calculation formula is as follows: Final premium = Base premium × (1 + floating rate linked to road traffic accidents) × (1 + floating rate A linked to traffic safety violations). According to regulations, the downward floating rate can only decrease by a maximum of 30%, meaning if the vehicle owner has driven safely for three consecutive years without any claims, the floating rate can decrease by 30%; conversely, the upward floating rate can increase by a maximum of 30%. Failure to pay compulsory traffic insurance may result in the traffic management department of the public security authority detaining the vehicle and imposing a fine of twice the amount of the unpaid premium. Compulsory traffic insurance is mandatory and must be paid. The role of compulsory traffic insurance: With the continuous increase in domestic vehicles, traffic accidents are frequent, but many responsible parties are unable to compensate for the victims' losses, causing irreparable hardships to the victims and their families. With the involvement of compulsory traffic insurance, when the responsible party is unable to compensate, the insurance company can help alleviate the difficulties caused by the traffic accident for the victims and their families. The liability limits are divided into death and disability compensation limits, medical expense compensation limits, property loss compensation limits, and compensation limits for the insured party who is not at fault in the road traffic accident.

What should vehicles do when navigating mountain curves?

When navigating curves on mountain roads, vehicles should adhere to the principles of 'reduce speed, sound the horn, and keep to the right.' Below is a detailed introduction to precautions when turning: 1. Mountain roads: When navigating curves on mountain roads, vehicles should follow 'reduce speed, sound the horn, and keep to the right.' 2. Left turns: For left turns, drivers should signal in advance and stay as close to the center of the road as possible to facilitate vehicles behind and those making right turns. Speed should be slower than during the day, and at intersections or curves, use high and low beams to alert oncoming vehicles while strictly adhering to traffic regulations by keeping to the right. Vehicles must reduce speed when turning.

When parking without turning off the engine, should you release the clutch or the foot brake first?

You can release either one first, but it is generally recommended to release the clutch first. Below are the relevant explanations: 1. Operate slowly: When braking, pressing the clutch and brake slowly will prevent the engine from stalling. Additionally, during the vehicle's forward movement, the speed must also be slow to ensure that you have time to think about any operation if you are not yet proficient. 2. Only release the clutch and brake pedals after shifting to neutral: If the vehicle is still in 1st gear, even if the car has come to a stop, releasing the clutch and brake too quickly can still cause the engine to stall due to the clutch being released too fast.

What does it mean when the subject 4 reservation is still under processing?

When the subject 4 reservation is still under processing, it means there are too many applicants for the subject 4 exam, so it is currently queuing for processing and will continue to show as under processing. Methods for reserving subject 4: There are two methods to reserve subject 4. The first is to reserve it together with subject 3. After completing subject 3, you can take the subject 4 exam on the same day. In some regions, you can directly take the exam within 7 days after completing subject 3 without needing to reserve. The second method is to reserve subject 4 separately, following the same procedure as other exam subjects, by operating on the 12123 APP. Make sure to select "Subject 3 Safety and Civilization Knowledge Test" as the exam subject. Tips for reserving subject 4: Choosing the "System Allocation Mode" can to some extent improve the success rate of reservation, but the exam session and time will not be fixed. Content and format of the subject 4 exam: The main assessment content includes safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. The exam consists of 50 questions, primarily in the form of case studies, images, animations, etc. The question types include true/false questions, single-choice questions, and multiple-choice questions. The full score is 100, with a passing score of 90.

What does 8t mean?

T stands for Turbo, which means turbocharging. A turbocharger is essentially an air compressor that utilizes the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage). The turbine, in turn, drives the coaxial impeller (located in the intake passage), which compresses the fresh air delivered by the air filter pipeline and then sends it into the cylinders. Expansion: When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase simultaneously, thereby enhancing the degree of air compression. Consequently, the engine's air intake increases accordingly, allowing for an increase in the engine's output power. The greatest advantage of turbocharging is that it can significantly boost the engine's power without increasing the engine displacement.
