What engine does the Huasong 7 use?

The Huasong 7 is equipped with the N20B20C engine, which delivers a maximum horsepower of 242 HP, a maximum power output of 178 KW at 5000 rpm, and a peak torque of 315 Nm. The engine in the Huasong 7 is a 2.0T turbocharged engine provided by BMW with their technology. For daily maintenance of the Huasong 7's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What brand is the special oil for Toyota cars?

Toyota's original special oil is Toyota Genuine Oil. The special oil models for Toyota include 0W20, 5W20, 5W30, 5W40, and 10W30. The viscosity of the oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The latter number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing Toyota's oil is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Loosen the oil drain plug with a wrench and use an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Remove the oil filter with a special wrench; apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the engine valve cover's oil filler port, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check that the engine oil level is within the standard range.

How many questions are there in the Subject 4 exam and what is the passing score?

According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the road driving skills and safe and civilized driving knowledge test for Subject 3 requires a score of 90 points to pass. There are a total of 50 questions, with each incorrect answer deducting 2 points. You can only miss 5 questions; exceeding this will result in failure. The full score is 100 points. Questions 1-10 are true/false questions; questions 11-40 are single-choice questions; and questions 41-50 are multiple-choice questions. The exam includes question types such as image analysis, animated case studies, and text descriptions. The scope of the Subject 4 exam includes: driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and hand signals; knowledge of traffic accident rescue and handling of common hazardous chemicals; comprehensive judgment of illegal behaviors and case analysis; knowledge of emergency avoidance; safe driving knowledge; and knowledge of driving ethics and civilized driving. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," there is no limit to the number of attempts for Subjects 1 and 4. If you fail the first attempt on the same day, you can retake the exam immediately. If you still fail, you need to reschedule the exam, and no additional fees are required for retakes. However, it is important to note that the validity period of the driving skills test permit is three years. If the applicant does not complete the exam within the validity period, the scores of any previously passed subjects will be voided. Subject 4, also known as the Subject 4 theory test or driver's theory test, is part of the motor vehicle driver's 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 safe and civilized driving knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Subject 4 is the colloquial term for the safe and civilized driving knowledge test under Subject 3. It is not a separate subject but is commonly referred to as Subject 4 because it is conducted after Subject 3. Officially, there is no Subject 4. The safe and civilized driving knowledge test is conducted after Subject 3. Subject 4 exam notes: Exam duration: The exam lasts 45 minutes. Number of questions: Depending on the type of driver's license being pursued, 50 questions are selected proportionally from the Subject 4 question bank. Question types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions, with question formats such as animated questions, image-based questions, scenario recognition questions, and text-based questions. There are a total of 3 subjects in the driver's license exam: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the examination of road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safe and civilized driving knowledge test.

What Causes the Clicking Sound During Low-Speed Gear Shifts in Wet Dual-Clutch Transmissions?

Wet dual-clutch transmissions producing clicking sounds during downshifts is a normal phenomenon. Reasons for abnormal noises during gear shifts: Since dual-clutch transmissions are equipped with two clutches, each independently connected to a set of gears controlling odd and even gears respectively, when the hydraulic servo system of the clutch or the transmission computer fails to precisely control the separation and engagement of gears, abnormal noises and jerks may occur. Gear shift mechanism: A wet dual-clutch transmission refers to a dual-clutch transmission where the clutch plates are immersed in transmission fluid. The gear shift is achieved through the alternating operation of two clutches, which ensures smooth gear shifting in wet dual-clutch transmissions. There are two types of dual-clutch transmissions: dry and wet.
