Trucks can be distinguished between National IV and National V by the following methods: 1. Different Labels: The simplest and most direct method is to look at the vehicle's environmental protection label, which has clear markings on the back. For new vehicles, you can check the vehicle's factory certificate; or log in to the Motor Vehicle Environmental Protection Website and query by entering the vehicle's VIN number and the last 6 digits of the engine number. 2. Different Emission Standards: The National IV emission standard is the fourth stage of national motor vehicle pollutant emission standards. The National V emission standard, known as the 'National V Standard,' has an emission control level equivalent to the fifth stage emission standard currently implemented in Europe.

How to Adjust a Motorcycle Rear Wheel?

First, start the motorcycle, then select the up arrow from the left side of the handlebar on the dashboard interface displaying the mileage. When a series of English letters appear, press the R button on the dashboard to display the detection values, then press the reset button on the dashboard. If the tire pressure is too low, it can cause the motorcycle tire to deform, making it prone to cracking, accelerating rubber aging, increasing the tire's contact area with the ground, and speeding up tire wear. If the tire pressure is too high, the tire's elasticity decreases, increasing the load on the tire during riding, making the motorcycle more susceptible to blowouts. The pressure value when the tire is cool best matches the labeled tire pressure. The most accurate tire pressure measurement is obtained when the motorcycle has been parked for three hours or has been ridden for no more than 1.6 kilometers.

How to Fix Water in Headlights by Yourself?

After the headlights are turned on for a period of time, the fog will be discharged out of the light through the vent pipe along with the hot air, which basically does not damage the headlights and electrical circuits. Then open the lamp cover, dry it, and check whether there is any damage or possible leakage on the surface of the headlight.

Can you temporarily park in the emergency lane?

Emergency lanes are not for temporary parking. They are reserved for ambulances, rescue vehicles, police cars, and other emergency vehicles. Regular vehicles are not allowed to park there. If an emergency occurs, you should stop at a service area. The emergency lane on highways is a lifeline, exclusively for emergency vehicles. Except in cases of vehicle breakdown, no vehicle is permitted to park in the emergency lane at any time. Otherwise, according to traffic laws, the driver will face a fine and a deduction of 6 points from their license. If a vehicle is involved in an accident or breaks down and needs to stop temporarily in the emergency lane, the driver must use hazard lights as a warning and place a warning triangle at least 150 meters behind the vehicle to alert oncoming traffic.

What are the reasons for the windshield washer not spraying water?

If the windshield washer is not spraying water, it may be due to a blockage inside. It is recommended to inspect and repair it as soon as possible. Checking the washer: Inspect the pipeline connections of the washer system. If they are loose or detached, they should be reinstalled and secured. If the plastic pipelines are aged, broken, or cracked, they should be replaced. Check the washer nozzle; if it is clogged, you can use a needle to unclog it. The nozzle angle should be adjusted. When the switch is pressed, the nozzle should spray the washer fluid onto the windshield. If it does not, check the spraying part or the circuit part. Special circumstances: Freezing of the washer fluid is a situation that can easily occur in cold winters. Frozen washer fluid can also cause the washer not to spray water. Therefore, if you are a car owner in the northern regions, be sure to add washer fluid with sufficient antifreeze capability. In cold weather, do not fill it to the top; filling it to two-thirds is sufficient. This is because the washer fluid is likely to freeze in cold conditions, and space for expansion needs to be reserved to avoid damaging the fluid reservoir.

Is a larger or smaller engine displacement better?

Whether a larger or smaller engine displacement is better depends on your usage: larger displacements are suitable for long-distance driving or frequent highway use, offering more comfort and power for climbing hills and overtaking; smaller displacements (below 1.6L naturally aspirated) are ideal for urban commuters, with lower fuel consumption and quieter operation. In China, passenger cars are classified by engine displacement: mini cars have displacements ≤1.0L; compact cars range from 1.0 to 1.6L; midsize cars from 1.6 to 2.5L; executive cars from 2.5 to 4.0L; and luxury cars have displacements >4.0L.
