BMW 1 Series dual-clutch transmission is a wet type, model: Magna wet 7DCT300. The related introduction of the dual-clutch transmission is as follows: Definition of dual-clutch transmission: The dual-clutch transmission (DCT) is different from the general automatic transmission system. It is based on a manual transmission but belongs to the automatic transmission. In addition to the flexibility of the manual transmission and the comfort of the automatic transmission, it can also provide uninterrupted power output. Advantages of dual-clutch transmission: The shifting time of the dual-clutch transmission is very short, even faster than that of the manual transmission, less than 0.2 seconds. The dual-clutch transmission eliminates torque interruption, which means the engine's power is always being reused and always working at its best, so it can save a lot of fuel. Compared with the traditional planetary gear automatic transmission, it is more conducive to improving fuel economy, and the fuel consumption can be reduced by about 15%.

Where are Dunlop tires produced?

Dunlop tires are produced in the UK. Dunlop is a Japanese tire brand, owned by the Sumitomo Group. Dunlop's run-flat tires are commonly known as "run-flat tires". The characteristic of run-flat tires is that they can still travel a certain distance at a certain speed when the tire pressure is zero, greatly improving driving safety without the need for a spare tire. Tires are often used under complex and harsh conditions, bearing various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have relatively high load-bearing performance, traction performance, and cushioning performance. According to their usage, tires can be divided into: passenger car tires, light truck tires, construction machinery tires, off-road vehicle tires, and agricultural and forestry machinery tires.

What are the reasons for a slightly shaking steering wheel?

The reasons for a slightly shaking steering wheel are: 1. Poor driving habits of the owner, caused by excessive braking; 2. Abnormal wear on the surface of the brake disc or brake pads; 3. Issues with the installation of the braking system, tires, or bearings; 4. Excessive braking force leading to overheating and deformation of the brake disc and brake pads. The function of the steering wheel is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. It mainly consists of a skeleton, foam, and the corresponding mounting clips or screw holes for the driver's airbag (DAB). The brake disc is a round disc that rotates as the vehicle moves. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop the vehicle.

What is the principle of automatic wipers?

Automatic wipers operate by driving the output shaft through a worm gear on the armature shaft, which then drives the output gear via an idler gear and idler shaft. The output arm, connected to the wiper linkage, is manipulated by the output shaft. When the motor rotates, the output arm and linkage are driven to move back and forth. Wipers are essential accessories installed on the windshield, designed to clear rain, snow, and dust that obstruct visibility. Wipers can be categorized by their driving mechanisms into mechanical, vacuum, pneumatic, hydraulic, and electric types. Modern vehicles typically use electric wipers due to their simple structure and convenient control.

Can temporary license plates be used for driving in the city?

Temporary license plates can be used for driving in the city. They are paper motor vehicle license plates issued for temporary road use, also known as temporary driving license plates. These are temporary vehicle driving permits issued by the public security vehicle management department for newly purchased vehicles before formal registration, with a validity period generally not exceeding thirty days. License plates, commonly referred to as vehicle plates, are panels hung on the front and rear of a vehicle, usually made of aluminum, sheet iron, plastic, or paper, inscribed with the vehicle's registration number, registration region, or other relevant information. License plates serve as a numbering and information registration system for vehicles, primarily enabling identification of the vehicle's region of registration and facilitating access to the vehicle's owner and registration details through the license plate number.

Why do vehicles need to add urea?

Vehicles add urea to meet emission standards, and only diesel vehicles require urea addition. National regulations mandate that electronically controlled diesel engine vehicles must use urea because diesel vehicles emit higher levels of exhaust gases. Adding urea helps reduce carbon oxides in the exhaust, lowering pollutant emissions and making diesel vehicles more environmentally friendly. Currently, most diesel engines employ Selective Catalytic Reduction (SCR) technology. This means that after the engine exhaust exits the turbocharger and before entering the vehicle's exhaust pipe, it must first pass through a catalytic converter for transformation. The urea injector on the exhaust pipe sprays urea under the control of the vehicle's onboard computer.
