New energy vehicles consist of the following components: 1. Electric drive system: including electronic controller, power converter, electric motor, mechanical transmission device, and wheels; 2. Power supply system: including power source, energy management system, and charger; 3. Auxiliary system: auxiliary power source, power steering system, navigation system, air conditioner, lighting and defrosting devices, wipers, and radio. New energy vehicles refer to vehicles that use fuels other than gasoline or diesel as power sources, which are divided into: 1. Hybrid electric vehicles, using conventional and unconventional fuels as power sources; 2. Pure electric vehicles, relying on motor-generated electricity as the power source; 3. Fuel cell electric vehicles, using hydrogen fuel as the power source.

What Causes the Raised Edge on Brake Discs?

Brake disc edge protrusion causes: Severe wear on the brake disc, which only requires replacement with a new one. The braking system is crucial for vehicles as it directly affects driving safety and stability. A car's braking system mainly consists of brake pads, brake discs, brake linings, vacuum booster pumps, master brake cylinders, and slave brake cylinders. Brake discs undergo wear during use, and uneven wear can lead to an uneven surface—some areas higher and others lower. This condition causes brake judder, affecting braking performance. If an uneven brake disc impacts braking effectiveness, it should be removed for resurfacing or replaced entirely.

Where to Set Up Keyless Entry?

Keyless entry in cars allows the driver to automatically unlock the anti-theft system without operating the smart key. Simply carrying the key and approaching the vehicle will trigger the system. Once inside, the driver can directly operate the one-touch start button to ignite the vehicle. The specific steps are as follows: 1. Open the driver's side door. 2. Release the electronic parking brake switch. 3. Depress the brake pedal all the way down until it cannot be pressed further, preparing to start the engine. 4. Press the one-touch start button. 5. All dashboard lights will illuminate, indicating that the engine has started successfully.

What Causes Black Exhaust Pipes?

Reasons and solutions for black exhaust pipes are as follows: 1. Poor fuel quality. Poor fuel quality not only leads to incomplete combustion but also causes carbon deposits to form in the engine. The optimal air-fuel ratio is 14.7:1, which ensures maximum combustion efficiency and reduces pollutant emissions. Solution: Try to use the same brand of engine oil. 2. Poor driving habits. Carbon buildup in cars is closely related to the driver's poor habits. Common behaviors like idling with the air conditioning on or not warming up the car in winter can result in an improper air-fuel ratio, causing the exhaust pipe to turn black. Solution: Develop good driving habits.

How Many Cylinders Does a V12 Have?

V12 refers to a 12-cylinder engine arranged in a V-configuration. Common V-type engines include V6, V8, V10, and V12, but there are also V3, V5, and V16 variants. Cylinder arrangements are generally categorized into inline (L-type), V-type, horizontally opposed (B-type), and W-type. A V-type engine divides all cylinders into two groups, positioning adjacent cylinders at a specific angle so that the two sets of cylinders form a plane with an angle between them. V-type engines have compact height and length dimensions, making them easier to install in vehicles. They allow for increased displacement and power by expanding cylinder diameter and are well-suited for higher cylinder counts. Additionally, they effectively counteract operational vibrations, resulting in greater stability.

What is the Principle of Car Steering?

Car steering principle is: By turning the steering wheel, the car transmits torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. The longer the rack pushes, the greater the angle the tires turn. When the vehicle leans forward, the engine makes both wheels rotate forward to maintain balance; when the vehicle leans backward, the engine makes the wheels rotate backward. Simply put, the steering wheel can be understood as a lever, with the radius of the steering wheel being the length of the force arm. The larger the steering wheel, the less effort is required. Currently, the automotive market universally adopts power steering. By detecting the direction in which the driver turns the steering wheel and the vehicle speed, the power steering motor controls the amount of steering torque applied to achieve the steering function.
