What is a Joint Venture Brand Car?

Joint venture brands mainly refer to brands and models developed by domestic automobile joint venture companies through purchasing and introducing foreign product technology platforms, with intellectual property rights belonging to the joint venture companies. Foreign partners provide technology, talent, brands, etc., for domestic assembly, but the core technology is still controlled by the foreign side. Below is an introduction to joint venture cars: FAW Group's joint venture brands: FAW-Volkswagen, FAW-Audi, FAW-Mazda (all produced in Changchun, Jilin), FAW-Toyota (produced in Changchun, Jilin; Tianjin; and Chengdu, Sichuan). Dongfeng Motor Group's joint venture brands: Dongfeng-Citroën, Dongfeng-Peugeot, Dongfeng-Honda (all produced in Wuhan, Hubei), Dongfeng-Nissan (produced in Guangzhou, Guangdong), Dongfeng-Yueda-Kia (produced in Yancheng, Jiangsu), Dongfeng-Fengxing (produced in Liuzhou, Guangxi), Dongfeng-Zhengzhou-Nissan (produced in Zhengzhou, Henan).

What is the normal speed of a motorcycle?

Different motorcycles have different speeds under different circumstances. The specific details are as follows: Measured on flat roads: 40-60 km/h is the economical speed for motorcycles. This speed is both safe and fuel-efficient, with minimal wear on the vehicle. Most motorcycles can reach 80-120 km/h. Racing motorcycles: Can reach a maximum speed of around 300 km/h. Oil change intervals: The break-in mileage for a new motorcycle is approximately 1,600 km. During the break-in period: 0-500 km: Speed should not exceed 45 km/h, and the first oil change should be done. 500-1,000 km: Speed should not exceed 55 km/h, and the second oil change should be done. 1,000-1,600 km: Speed should not exceed 80 km/h, and the third oil change should be done. After the break-in period, change the oil every 2,000-2,500 km. During normal operation, the speed should not exceed 90 km/h.

Do Imported Vehicles Come with a Certificate of Conformity?

Imported vehicles come with an engine certificate of conformity. The importance of the certificate and precautions when purchasing imported vehicles: Importance of the Certificate of Conformity: The certificate of conformity for imported vehicles, like standard certificates, includes a serial number and a barcode or QR code for scanning. The certificate is another crucial document for the vehicle and is essential for registration. Only vehicles with a certificate of conformity meet the national requirements for motor vehicle equipment quality and related standards. The numbers on the certificate must match the engine number and chassis number on the vehicle. Precautions When Purchasing Imported Vehicles: When purchasing, pay attention to the vehicle's source. Imported vehicles should be bought from domestic agents designated by the foreign car manufacturer. Carefully inspect all vehicle attachments and included tools to ensure they are complete. Check all parts of the vehicle for proper sealing and any signs of oil, gas, water, or electrical leaks. Also, pay special attention to the vehicle's mileage. Typically, a new vehicle should have less than 200 kilometers, and it should not exceed 1,000 kilometers at most.

What Emission Standard Does the Prado Meet?

The emission standard of the Prado is as follows: The Prado meets the China V emission standard. 1. The China V emission standard is the fifth stage national standard for motor vehicle pollutant emissions, also known as "China V Standard". 2. From China I to China V, each upgrade in the standard reduces vehicle pollution by 30%-50%. The China V Standard was implemented nationwide on January 1, 2017. Below is an introduction to vehicle exhaust emissions: 1. Vehicle emissions refer to harmful gases such as CO, hydrocarbons, nitrogen oxides (NOx), and PM (particulate matter) discharged from the exhaust. 2. These harmful gases are produced during the combustion process in the engine. The reasons for their production vary: CO is an intermediate product of incomplete fuel oxidation, occurring when oxygen is insufficient. High fuel mixture concentration and uneven mixture distribution can increase CO in the exhaust. 3. HC (hydrocarbons) are unburned substances from the fuel, caused by uneven mixture distribution or cold combustion chamber walls, leading to some fuel being emitted without complete combustion. 4. NOx is produced during the combustion process of fuel. PM is also a substance generated when fuel burns under oxygen-deficient conditions, most notably in diesel engines. This is because diesel engines use compression ignition, and diesel fuel is more prone to cracking under high temperature and pressure, producing visible carbon soot.

Should a new car be waxed or coated with crystal?

Waxing is inferior to crystal coating; waxing is cheaper than crystal coating. The price of a single waxing is less than one-tenth of crystal coating, which has no advantage in this regard. Crystal coating requires higher technical skills from the construction personnel and a better construction environment, and it takes more time. In terms of durability: a single waxing usually lasts 1-2 months, while crystal coating is more durable, generally lasting about 1 year. There are two types of waxing: one is direct waxing, which is relatively simple and has the lowest price, starting at around 350 yuan in first-tier cities. It is suitable for new cars and cars without scratches. After washing the car, car wax is directly applied to the surface. Just like applying a layer of cream directly to our face after washing, it forms a thin protective layer between the car and the air, preventing rainwater, dust, etc. from directly contacting the car paint, thus protecting the car paint. This protection is also the weakest. Generally, it will be washed off after two car washes. "Crystal" is actually a type of glass cellulose, called "crystal" because of its gloss, with the scientific name of full silane. It exists in liquid form. After curing, it forms a transparent protective layer on the car paint surface, isolating external substances from damaging the paint. At the same time, the protective layer itself has a certain hardness, just like applying a tempered film to a mobile phone.

How to Solve the Abnormal Noise from the Sylphy Water Pump Bearing?

Sylphy water pump bearing abnormal noise solution is as follows: You can first conduct a test by removing the belt and starting the engine to listen for any abnormal noise. After the belt is removed, the water pump does not operate. If the abnormal noise persists, it indicates that the water pump bearing is not damaged; otherwise, the water pump bearing is faulty. When using this method, the engine must be turned off within 1 minute to avoid engine damage. If the bearing is damaged, it needs to be replaced. The repair method for water pump leakage is as follows: 1. Remove the water pump: First, drain the coolant from the water pump, remove the V-belt, use a special tool to press out the water pump pulley, and then remove the water pump. 2. Disassemble the water pump: Use a special tool to first remove the water pump bearing, then remove the water pump impeller and seal assembly from the water pump bearing. 3. Replace the sealing ring, new gasket, new V-belt, and new pulley. 4. Assemble: Use a special tool to first press the bearing onto the water pump impeller, then press the water pump impeller and seal assembly into the specified position, and press the water pump bearing onto the water pump pulley seat. During the operation, the bearing end face should be pressed flush with the housing, and the water pump impeller plane should be 0.1-0.3mm lower than the pump housing plane. 5. Inspection: The assembled water pump should have a shaft that can rotate flexibly, and the water pump bearing should have no noticeable radial clearance. 6. Fill with new coolant.
