What are the running-in tips for new automatic transmission cars?

Running-in tips for new automatic transmission cars are as follows: 1. Pay attention to the running-in mileage: The running-in mileage for new cars is generally 1,000 to 3,000 kilometers. 2. Emphasize warming up the car: Do not start driving immediately after starting the car; wait until the water temperature reaches the normal temperature before moving. 3. Vary the speed: Avoid maintaining a constant speed for extended periods. Unlike manual transmission cars where you can select specific gears for running-in, automatic transmission cars can only achieve this by continuously varying the speed. 4. Avoid heavy loads during running-in: During the running-in period within the specified mileage, try to drive with no load or light loads and avoid full loads. 5. Check equipment: Before hitting the road, test all the gauges to ensure they display normal functions for all parts.

Are fenders and wheel arches the same?

Fenders and wheel arches are the same; fenders are also known as wheel arches. Below is relevant information about fenders: 1. A fender is a body panel that covers the wheel, named for its resemblance to a bird's wing in older vehicle designs. Based on their installation position, they are divided into front fenders and rear fenders. The front fender is installed near the front wheel and must accommodate the maximum space required for the wheel's rotation and movement. Therefore, designers use a "wheel travel diagram" based on the selected tire model and size to verify if the fender's design dimensions are appropriate. 2. The function of the fender is to prevent sand, gravel, and mud kicked up by the wheels from splashing onto the underbody of the vehicle during driving. As such, the materials used must be resistant to weather aging and have good formability. Some vehicles' front fenders are made of a certain elastic plastic material, which provides cushioning and enhances safety.

Are the toll fees the same for 7-seater and 5-seater vehicles?

7-seater and 5-seater vehicles have the same toll fees, with no difference in charges. According to the 'Toll Road Vehicle Classification Standards,' both are uniformly classified as Class 1 small passenger vehicles. Therefore, the highway toll standards for these two types of vehicles are the same. More details are as follows: 1. During annual inspections: The annual inspection is likely where 5-seater and 7-seater vehicles differ the most. According to regulations, small passenger vehicles with 7 seats or more continue to follow the original policy of inspection every 2 years, while those with 6 seats or fewer can be inspected every 6 years. 2. Compulsory traffic insurance is mandatory for vehicle owners every year. For 5-seater vehicles, the annual fee is 950 yuan, while for 7-seaters, it is 1100 yuan.

What Causes High Exhaust Temperature Alarm in China VI Diesel Vehicles?

China VI diesel vehicles high exhaust temperature alarm causes: The idle switch does not close, the idle contact is disconnected, the ECU determines that the engine is under partial load. At this time, the ECU determines the fuel injection quantity and injection time based on the air flow sensor, crankshaft position, and speed signals. The exhaust temperature increases because modern vehicles are equipped with three-way catalytic converters. Types of exhaust systems: Exhaust temperature protection is one type of compressor temperature protection device. Effects of excessive temperature: During compressor operation, certain factors can cause the exhaust temperature to exceed normal values. This not only increases compressor power consumption but also causes lubricating oil to carbonize, degrading its performance and affecting the compressor's normal operation. To avoid excessively high exhaust temperatures, an injection valve can be used to control the exhaust temperature.
