The D license permits the operation of three-wheeled motorcycles, the E license allows the operation of two-wheeled motorcycles, and the F license only permits the operation of light motorcycles. Below is an introduction to motorcycle driving licenses: Motorcycle driving licenses generally refer to driving licenses. The full name of a driving license is a motor vehicle driving license, also known as a "driver's license," which is a certificate required by law for individuals to operate motor vehicles. Driving a motor vehicle requires certain driving skills, and without these skills, operating a motor vehicle recklessly may lead to traffic accidents. Driving without a license is prohibited. However, for those who possess safe driving skills, the document that permits them to drive on the road is the "driving license." A motorcycle driving license is a type of "permit." Classification of Motorcycle Driving Licenses: Among motorcycle driving licenses, the D license has the highest rank. In addition to allowing the operation of ordinary three-wheeled motorcycles, it also permits the operation of all vehicle types allowed by the E and F licenses.

How to Turn on the Fog Lights for Subject Three?

The fog light switch is located on the vehicle's lighting combination switch, specifically behind the left side of the steering wheel. You need to rotate the combination switch to turn on the fog lights. Here are some important notes: Purpose of fog lights: Fog lights are used in low visibility conditions. Exam tips: During the Subject Three test, there will be a voice prompt to start the lighting simulation operation. Before this, you should check if all lighting switches are turned off (including the lighting control lever on the steering wheel, which should be reset). If the previous examinee did not completely turn off the lights and you proceed directly to the test, you will fail. The fog light button for Subject Three is located on the left side of the driver's seat. First, turn on the vehicle's lights, then some models use a button to activate the fog lights, while others require rotating to turn them on. For most vehicle models, the fog light button is on the left side of the driver's seat. Some vehicles have buttons to turn on the front and rear fog lights. These buttons are usually located near the dashboard and labeled with fog light symbols. After turning on the lights, pressing the front fog light button will activate the front fog lights, and pressing the rear fog light button will activate the rear fog lights. Some models have a single fog light button marked with a fog light symbol. Turning this button to the ON position will activate the front fog lights, and turning it further down will simultaneously activate both front and rear fog lights. During the exam, pay attention to the instructions and remember not to turn on both front and rear fog lights at the same time. Also, always remember to turn off all vehicle lights.

What engine is used in the Aeolus Yixuan?

The engine used in the Aeolus Yixuan is a gasoline engine independently developed and produced by Dongfeng, belonging to a domestically manufactured engine. The engine model of the Aeolus Yixuan is DFMA15, with a maximum power of 110kW, a maximum torque of 230Nm, and a maximum horsepower of 150. For daily maintenance of the Aeolus Yixuan engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, the oil should be changed regularly based on usage conditions, with an appropriate amount of oil. When engine oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, bypassing through the relief valve and bringing contaminants back to the lubrication area, 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 powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.
