Check the Certificate of Conformity: The vehicle's certificate of conformity contains key information, including the emission standard the vehicle complies with. Check the Environmental Protection List: Review the environmental protection information list provided with the vehicle when purchasing through official channels. The first section of this list includes details about the vehicle's emission stage, clearly indicating the emission standard of the model. Query via Specialized Websites: Use specialized websites to verify the emission standard.

What is the difference between left and right fuel tanks?

For automobiles, there is no difference whether the fuel tank is located on the left or right side. The following is an introduction to the position of the car fuel tank: 1. When refueling, the vehicle can be adjusted, so it is impossible to be unable to refuel due to the different positions of the fuel tank. 2. Regarding the position of the fuel tank, there is no international unified requirement, and there are no relevant legal requirements in China. The fuel tank can be on either the left or right side. 3. There are two types of driving rules in the world: left-hand traffic and right-hand traffic. In countries with left-hand traffic, the fuel tank opening is generally on the left side. Correspondingly, in countries with right-hand traffic, for the convenience of refueling, the fuel tank is generally on the right side. 4. In left-hand traffic countries, the driver's cab is on the right side, while in right-hand traffic countries, the driver's cab is on the left side. The fuel tank is located diagonally opposite the driver's cab, and the position of the fuel tank opening is arranged on the diagonal line of the driver's seat to avoid accidents during refueling.

What to Do When the Motorcycle Handlebar Steering is Not Flexible?

First, check whether the steering stem bearing clearance is appropriate. If the clearance is too small, adjust the adjusting nut to set the clearance to the proper position. Check whether the front shock absorber sleeve is bent. If it cannot be straightened, replace it with a new sleeve. If the oil levels in the two sleeves are unequal or insufficient, add an equal amount of oil. For older motorcycles, if the steering bearing is severely worn, it should be replaced without hesitation.

Can the Air Conditioning Be Turned On Without Starting the Car?

It is possible to turn on the air conditioning without starting the car, but the air blown out by the blower will only be the ambient air inside the cabin. Below is a detailed introduction to car air conditioning: 1. The car air conditioning compressor is driven by the engine's power. If the engine is not started, the compressor naturally will not work. 2. The car air conditioning system is designed to cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The air conditioning system has become one of the indicators of a car's full functionality. 3. When the car is turned off, the air conditioning compressor does not operate. The natural air blown by the blower is powered by the battery. Prolonged use of the air conditioning without starting the car can drain the battery, potentially leaving the car unable to start or causing long-term battery depletion. This applies only to traditional fuel vehicles; new energy vehicles do not face this issue.
