Here are the methods to determine the national emission standard of a vehicle: 1. Check the vehicle's environmental protection label, which usually has clear markings on the back. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Take the vehicle registration certificate (original or copy) to the vehicle management office for inquiry. 4. For new cars, you can refer to the vehicle's factory certificate, which contains this information. However, the vehicle certificate is usually kept at the vehicle management office, so it's advisable to make a copy when purchasing a new car. 5. Make a rough estimation based on the year the vehicle was registered.

I'm an ordinary driver who owns a used car, and I only realized the importance of emission standards after encountering traffic restrictions before. Checking the national emission standard is simple: first, look at the environmental label on the inside of the windshield—the round sticker directly shows the national standard level, such as blue for National IV. If the label is missing, check the vehicle registration certificate or the motor vehicle license, where the emission standard is clearly stated in the corresponding column. When I sold my car last time, I used the VIN code to check—just enter the 17-digit code on the vehicle management office’s official website or a free app, and you’ll get the result in a minute or two. Don’t underestimate this—in big cities like Beijing and Shanghai, vehicles below National III are restricted from entering urban areas, or you’ll face fines and points deducted. Always check before buying a used car to avoid ending up like my neighbor, who got stuck on a long trip and wasted money for nothing.

Where is the fuel pump located in the BYD Song?

The fuel pump of the BYD Song is located inside the engine, installed within the oil pan. Here are the relevant details about the fuel pump: Function of the fuel pump: The fuel pump's role is to draw gasoline from the fuel tank and pressurize it through the pipelines and fuel filter into the float chamber of the carburetor. Gasoline serves to cool and lubricate the fuel pump. If fuel is not replenished promptly after the fuel warning light comes on, the cooling and lubrication effects will diminish, potentially causing damage. Impact of fuel quality on the fuel pump: Impurities in low-quality gasoline can clog the fuel supply system and wear out the fuel pump, leading to damage. Early failure of the fuel pump is often caused by the use of inferior fuel. Electric fuel pump: An electric fuel pump is not driven by the camshaft but operates through electromagnetic force repeatedly moving the pump diaphragm. This type of electric pump allows for flexible installation locations and helps prevent vapor lock.

Is the BYD Song Fuel-Efficient?

BYD Song is not fuel-inefficient. The fuel consumption of the Song Pro gasoline version is 7.0L/100km, while the BYD Song Pro DM version consumes 1.4L/100km. The following factors affect fuel consumption: Driving Habits: Personal driving skills have a significant impact on a car's fuel consumption. For short trips of just a few kilometers, due to the mechanical design characteristics of the vehicle, it takes some time of operation to reach optimal efficiency. If the car hasn't fully warmed up during these short trips, higher fuel consumption is inevitable. Road Conditions: Road conditions include whether the road is smooth, the level of friction, the size of inclines, and whether there is traffic congestion. Generally, roads with many sharp turns and frequent braking will result in significantly higher fuel consumption. During peak commuting hours in the morning and evening, it's common to travel only a few kilometers in an hour, leading to fuel consumption that can be more than three times higher than during smooth traffic conditions.

What is the tire model of BYD Song Plus DM-i?

BYD Song Plus DM-i has three tire models: 235/50R19, 235/55R18, and 245/45R20. The first number 235 represents the tire width of 235MM, 50 indicates the tire's aspect ratio is 50%, meaning the section height is 50% of the width, the letter R stands for radial tire, and 16 represents the rim diameter of 16 inches. The BYD Song Plus DM-i has a fuel consumption of 6.9L per 100 kilometers. In addition to the model, the tire also marks the following common data: Tire cord material: Represented by Chinese Pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under specified conditions. Letters from A to Z represent the certified speed ratings of the tire from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim specification compatible with the tire. For practical use, such as standard rim 5.00F.

What is the reason for BYD's alarm to keep ringing?

BYD's alarm keeps ringing due to a faulty door contact switch, which can also cause the alarm to sound. It is necessary to go to a repair shop for maintenance. The sensitivity of the anti-theft sensor is too high. There is a sensitivity adjustment knob on the anti-theft vibration sensor, which can be fine-tuned. Alarm working principle: When the sensor is struck or shaken, the ball inside the chamber will roll. When it rolls away from a smaller secondary electrical contact element, the circuit formed by this secondary electrical contact element and the central electrical contact element will be disconnected. Controller ball displacement: At this time, the switch will open, indicating that the controller ball has been displaced. As the ball continues to roll past other secondary electrical contact elements, the circuit will repeatedly close and open until the ball finally stops rolling.

Can the BYD Han DM be used without charging?

Han DM hybrid cannot be used without charging. Because the Han DM hybrid is a plug-in hybrid, unlike a conventional hybrid, it requires external charging to replenish its electrical energy. Its technology primarily allows for external charging, enabling it to drive in pure electric mode. Once the battery is depleted, it switches to hybrid mode (primarily using the internal combustion engine) and recharges the battery as needed. Based on the connection method of hybrid power drive, hybrid vehicles are generally divided into three categories: Series Hybrid Electric Vehicle (SHEV): Mainly consists of an engine, generator, and drive motor, which are connected in series to form the HEV power system. Parallel Hybrid Electric Vehicle (PHEV): Both the engine and the drive motor serve as power units. The power outputs of these two units can be combined or used separately. Power-Split Hybrid Electric Vehicle (PSHEV): Combines the structures of series and parallel hybrids to form an electric vehicle, mainly composed of an engine, electric generator, and drive motor as the three major power units.
