What is the difference between T3 and T4 brake fluid for cars?

The difference between T3 and T4 brake fluid lies in their applicable speed ranges: T3 brake fluid is suitable for speeds between 90 to 140 kilometers per hour, while T4 is designed for speeds ranging from 140 to 180 kilometers per hour. It is crucial not to mix different types of brake fluid due to the following hazards: 1. Mixing can degrade the performance indicators of the brake fluid or trigger chemical reactions, thereby reducing the vehicle's braking effectiveness; 2. The fluid's temperature resistance may decrease, compromising driving safety. The procedure for replacing brake fluid is as follows: 1. Park the vehicle on level ground, turn off the engine, open the hood, and drain the old fluid from the reservoir; 2. Use a funnel to refill the reservoir with new brake fluid; 3. Lift the vehicle using a jack, starting with the rear wheels, and remove the tires; 4. Take off the rubber dust caps on the brake calipers; 5. Loosen the bleeder screws with a wrench, attach a rubber tube to them, and connect the other end to a drainage bottle; 6. Have someone press the brake pedal inside the car while observing the fluid drainage until the fluid level in the engine compartment reservoir reaches the lower limit.

What is the 0-100 km/h acceleration time of the H2R?

According to official data, the H2R's 0-100 km/h acceleration time is 2 seconds, while the H2's 0-100 km/h acceleration time is approximately 2.8 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in layman's terms, represents how much force is available. The greater the torque, the more force is available to propel the vehicle, resulting in faster acceleration. The H2R has a maximum torque of 165 Nm, achieving 0-100 km/h in 2 seconds. The H2 has a maximum torque of 137 Nm, achieving 0-100 km/h in 2.8 seconds. Transmission efficiency: The transmission is the medium for transferring power and inevitably involves power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The H2R is equipped with a 6-speed transmission. Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit is Hp/T). The higher the power-to-weight ratio, the faster the acceleration. The H2R has a power-to-weight ratio of 1540 hp/T, achieving 0-100 km/h in 2 seconds. The H2 has a power-to-weight ratio of 925 hp/T, achieving 0-100 km/h in 2.8 seconds.

From being one of China's earliest modern industrial pioneers, it has developed into the country's largest small vehicle and engine manufacturer with total assets exceeding 30 billion yuan and over 40,000 employees. It ranks among the top four in China's automotive industry and leads the mini-vehicle sector, standing as one of the pioneering enterprises in China's independent automotive innovation. 2. Business Areas: Changan Group's industries cover three main sectors: complete vehicles and engines, military products, and components. 3. Vehicle Models: Changan Automobile has launched product series including mini trucks and vans, sedans, MPVs, SUVs, trucks, and medium-to-large buses. It has successively introduced China's first fully independently developed vehicle—the Changan CM8, concept cars like the Jiexun, Yangtze Sturgeon, and Longteng, the MPV 'Landwind Fashion,' and the CV11. Additionally, upcoming models include the CV6, CV7, and CV8, which are economical and mid-level sedans.

What does AHD reversing camera mean?

AHD reversing camera refers to a high-definition reversing image system installed at the rear of the vehicle. It consists of ultrasonic sensors, a controller, a display, and a buzzer. Its function is to allow the driver to see the situation behind the vehicle on the display when reversing, avoiding accidents caused by the driver's inability to see the rear situation during reversing, thereby improving driving safety. The method to activate the reversing camera is: shift the vehicle into reverse gear, and the reversing camera will automatically turn on. The automotive reversing camera system uses a far-infrared wide-angle camera device, which can clearly display obstacles behind the vehicle on the in-car display screen.

When is it not necessary to paste the car insurance sticker?

Since 2018, the car insurance sticker no longer needs to be pasted, but this does not mean that the car does not need to be insured. Additional information: 1. Relevant laws: Compulsory traffic insurance is one of the types of car insurance that must be purchased as stipulated by the state. The compulsory traffic insurance sticker must still be pasted on the car. According to the "Road Traffic Safety Law", any vehicle driving on the road without the inspection qualification sticker or compulsory traffic insurance sticker, or without carrying a driver's license or vehicle license, will be detained by the public security traffic management department in accordance with the law. The compulsory traffic insurance sticker and the motor vehicle inspection qualification sticker should be pasted in the upper right corner of the motor vehicle. Failure to paste or violation of regulations will result in a fine. 2. Notes: The environmental protection sticker for motor vehicles also does not need to be pasted. In the future, all vehicle-related inspection information can be queried in the local vehicle management database. Pickup trucks will be treated the same as family cars, and there is no need to paste insurance stickers or environmental protection stickers. The reflective strips on the rear of the vehicle also do not need to be pasted. Although these stickers do not need to be pasted, car insurance must still be purchased in accordance with regulations, which is also for the safety of the car owner. Remember to bring your driver's license and vehicle license when you go out.
