GF-6 standard is divided into GF-6A and GF-6B. The following are the specific details of the GF-6 standard: 1. Effective Date: May 2020, when GF-6A came into effect, replacing GF-5 and earlier standards. 2. Incompatibility with Older Standards: GF-6B is not compatible with previous older standards and is only recommended for use in new vehicles requiring 0W-16 oil, primarily Japanese cars at present. 3. Not Recommended Oils: Similar to the GF-5 standard, GF-6A/B does not recommend any xW-40 viscosity oils, mainly due to greater consideration for fuel economy. Currently, API-SP can still be found in xW-40 viscosity oils.

Will I Get Penalty Points for Making a U-Turn After Accidentally Entering a One-Way Street?

If you are caught by an electronic surveillance camera while driving in the wrong direction on a one-way street, you will be penalized with 3 demerit points and a fine. Definition of Wrong-Way Driving: Wrong-way driving refers to motor vehicles or non-motor vehicles traveling on the left side. Article 35 of the "Road Traffic Safety Law of the People's Republic of China" stipulates: Motor vehicles and non-motor vehicles shall drive on the right side. Hazards of Wrong-Way Driving: Driving in the wrong direction is a serious intentional traffic violation that can lead to traffic congestion, reduced road capacity, and in severe cases, major traffic accidents, even resulting in fatal consequences. Typically, in accidents caused by wrong-way driving, the party driving in the wrong direction bears full responsibility.

What are the requirements for setting up accessible parking spaces?

Accessible parking space setup requirements include that regardless of whether the parking area is above or below ground, the most convenient parking spaces with the shortest distance to the entrance/exit should be designated as accessible parking spaces. If possible, accessible parking spaces should be located next to the entrance/exit. The ground of accessible parking spaces should be flat, slip-resistant, and free of water accumulation, with a slope not exceeding 1:50. There should be a wheelchair passage at least 1.20 meters wide on one side or between adjacent parking spaces. The ground of accessible parking spaces should be marked with parking lines, wheelchair passage lines, and accessible signage. Accessible parking spaces are designated for vehicles driven or used by individuals with physical disabilities, and these spaces are marked with a "wheelchair" symbol. According to State Council Order No. 622, if vehicles other than those driven or used by individuals with physical disabilities occupy accessible parking spaces, thereby affecting their use by individuals with physical disabilities, the traffic management department of the public security authority shall order corrections and impose penalties in accordance with the law.

How many kilometers per hour is a speed of fifty yards?

A speed of fifty yards is equivalent to 50 kilometers per hour. Below is an introduction about vehicle speed: Concept of vehicle speed: The distance a vehicle travels per unit of time, referred to as vehicle speed. Common units are kilometers/hour or meters/second. Vehicle speed is one of the three parameters describing traffic flow and holds significant importance in traffic flow theory research. Classification of vehicle speed: Vehicle speed can also broadly refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Speed limit requirements during special periods and adverse weather: During nighttime (from 10 PM to 5 AM the next day), the speed of passenger vehicles must not exceed 80% of the daytime speed limit. Additionally, according to the Road Traffic Safety Law and its implementation regulations, when driving on ordinary roads under conditions of fog, rain, snow, dust, or hail with visibility less than 50 meters, as well as on icy or muddy roads, the speed limit is 30 kilometers per hour.

What is the fog light symbol?

The front fog light symbol features three diagonal lines on the left, intersected by a curved line, with a semi-elliptical shape on the right. The rear fog light symbol has a semi-elliptical shape on the left and three horizontal lines on the right, intersected by a curved line. Front and rear fog lights are easily distinguishable: the front fog light's light lines point downward, while the rear fog light's light lines are straight. Function of car fog lights: The purpose of the rear fog light is to make the vehicle more visible to drivers behind in low-visibility conditions such as fog, snow, rain, or dust. Precautions for using fog lights: Car fog lights increase visibility distance, improving the driver's and other road users' ability to see each other, allowing approaching vehicles and pedestrians to spot each other from farther away. Under normal circumstances, fog lights should not be used; they are only necessary in thick fog. Even in heavy rain, only low-beam headlights are needed, as fog lights provide no additional benefit to the driver.

How are engines classified?

Automobile engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems based on their power sources. The details are as follows: 1. Diesel Engine: The advantages of diesel engines include high torque and good fuel economy. The working process of a diesel engine shares many similarities with that of a gasoline engine, as each working cycle also undergoes four strokes: intake, compression, power, and exhaust. However, since diesel fuel is used in diesel engines, its viscosity is higher than that of gasoline, making it less prone to evaporation. Additionally, diesel has a lower autoignition temperature than gasoline. As a result, the formation of the combustible mixture and the ignition method differ from those of gasoline engines. 2. Gasoline Engine: A gasoline engine is an engine that converts internal energy into kinetic energy using gasoline as fuel. Due to the low viscosity and high volatility of gasoline, a fuel injection system can be used to inject gasoline into the cylinder. After compression reaches a certain temperature and pressure, a spark plug ignites the mixture, causing the gas to expand and perform work. Gasoline engines are characterized by high rotational speed, simple structure, lightweight, low cost, smooth operation, and ease of maintenance. They are widely used in automobiles, especially in small cars. 3. Electric Vehicle Motor: An electric vehicle motor is an electromagnetic device that converts or transfers electrical energy based on the principle of electromagnetic induction. Also known as a motor, it is represented by the letter "M" in circuits. Its primary function is to generate driving torque, serving as the power source for electric vehicles. 4. Hybrid System: A hybrid system refers to a vehicle that uses both gasoline and electric power for propulsion. The advantage lies in the fact that when the vehicle starts and stops, it relies solely on the electric motor. The engine does not operate until a certain speed is reached, thereby keeping the engine in its optimal working condition. This results in excellent performance and very low emissions. Moreover, the electricity is generated by the engine, requiring only refueling.
