A car is mainly composed of four major assemblies: the body, engine, chassis, and electrical equipment. It is the power unit of the car. Its function is to burn fuel to generate power, which then drives the wheels through the chassis's transmission system, enabling the car to move. There are two types of engines: gasoline engines and diesel engines. A gasoline engine consists of the crankshaft-connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system. Diesel engines use compression ignition, so they do not have an ignition system. The chassis serves to support and mount the car's engine and its components and assemblies, forming the overall shape of the car. It receives power from the engine, enabling the car to move and ensuring normal operation. The chassis consists of four parts: the transmission system, driving system, steering system, and braking system. The body is mounted on the chassis frame and provides space for the driver and passengers or for carrying goods. The electrical equipment consists of the power source and electrical devices. This includes the power battery and generator. Electrical devices include the engine starting system, gasoline engine ignition system, and other electrical equipment.

What to Do If You Can't Return a Yong'anxing Bike?

If you realize it in time, simply return to the parking spot to lock the bike and click "End Trip" on the mobile app. Since manual locking + ending the trip via the app are both required, forgetting either step may result in the bike being used by other users. You can report the issue via phone call. If connected, official staff will handle it promptly, but due to the large user base, the probability of reaching customer service is low. Yong'anxing Bikes has an official service group where you can contact customer support to report issues. This method is more efficient than phone calls.

What are the quick tips for passing the Subject One and Four exams?

1. Priority principle: Yield to straight-moving vehicles when turning, give way to vehicles from the right, and right-turning vehicles yield to left-turning ones. Vehicles in a safer position yield to those in more dangerous situations, and unobstructed vehicles have the right of way. 2. Safety: Let others go first: yield by slowing down, stop and yield, give way politely, and slow down to avoid. Slow: pass slowly, decelerate, proceed steadily, gradually, pass at a reduced speed, lower speed uniformly. Observe: observe in advance, carefully, thoroughly, and scan the surroundings. 3. Mistakes: Acting without consideration: proceed directly, accelerate through. Overreacting: emergency braking, jerking the steering wheel, turning sharply, stomping on the brakes.

What do 91V and 94V mean on tires?

91 refers to the tire load index of 615kg, and V stands for the speed rating with a maximum speed of 240km/h. 94=This tire has a maximum load capacity of 670kg, V=The maximum speed of this tire is 240 kilometers per hour. Tires are one of the most important components of a vehicle, and their main functions include: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Transmitting traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability; working together with the vehicle suspension to mitigate impacts during driving and dampen the resulting vibrations; 3. Preventing severe vibrations and early damage to vehicle components, adapting to the high-speed performance of the vehicle and reducing driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency.
