The principle of plug-in hybrid electric vehicles is to power the car by simultaneously utilizing the internal combustion engine and the electric motor, thereby driving the vehicle. This results in improvements in fuel economy, comfort, and acceleration to a certain extent. Advantages of plug-in hybrids: Compared to non-plug-in hybrid vehicles, plug-in hybrid electric vehicles have larger battery capacities, which support longer driving ranges. If the vehicle is used primarily for short-distance trips and good charging conditions are available, a plug-in hybrid can operate without refueling, functioning as a pure electric vehicle and offering the benefits of pure electric cars. Differences between plug-in hybrids and conventional hybrids: Conventional hybrid vehicles have very small battery capacities, supplying/recovering energy only during start-stop, acceleration, and deceleration. They cannot be charged externally and cannot operate in pure electric mode for long distances. In contrast, plug-in hybrid vehicles have relatively larger batteries, can be charged externally, and can operate in pure electric mode. Once the battery is depleted, they switch to hybrid mode and recharge the battery as needed.

I drive a lot, and the principle of plug-in hybrid electric vehicles is actually pretty cool: at its core, it combines an electric system with a fuel engine. You can charge the battery using a power outlet, just like charging a phone. Once fully charged, it can run purely on electricity for several dozen kilometers, making it ideal for short commutes. When the battery is nearly depleted, the system automatically switches to the fuel engine for propulsion while also recharging the battery in reverse, so you don’t have to worry about getting stranded on long trips. The clever part of this design is its intelligent mode-switching capability—it operates quietly and smoothly with full electric drive during starts and low speeds, only engaging the engine at higher speeds for fuel efficiency. From my experience, a larger battery capacity means more electric usage, reducing trips to the gas station, while the engine ensures reliability. Overall, it’s much more flexible than a pure electric car.

What does ESP mean in cars?

ESP in cars stands for Electronic Stability Program, which is a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. It analyzes vehicle driving state information from various sensors and then sends correction instructions to ABS and ASR to help maintain dynamic balance. The ESP system consists of a control unit and steering sensors (monitoring the steering angle of the steering wheel), wheel sensors (monitoring the speed of each wheel), skid sensors (monitoring the state of the vehicle rotating around the vertical axis), and lateral acceleration sensors (monitoring the centrifugal force during turns).

What is a car chassis composed of?

An automobile chassis is composed of the transmission system, steering system, running system, and braking system. The transmission system includes the clutch, gearbox, final drive, half-shaft, universal joint, and drive shaft. The running system consists of the frame, stabilizer bar, axle, wheels, crossmember, shock absorber, steering knuckle, control arm, and catalytic converter. The steering system includes the steering shaft and tie rod. The braking system comprises the brake disc, brake caliper, and brake pads. The chassis serves to support and install the car's engine and its various components and assemblies, forming the overall shape of the vehicle and receiving the engine's power to enable motion and ensure normal driving. Additionally, a well-designed chassis can ensure the driver's safety.

What does 9AT mean in cars?

9AT in cars refers to an automatic transmission with 9 forward gears. The 9AT transmission controls different combinations of planetary gears through shifting components, achieving a setup of 9 forward gears and 1 reverse gear. The advantages of 9AT include fuel efficiency and faster acceleration, while the disadvantages are higher cost and complex structure. There are four types of automatic transmissions: hydraulic automatic transmission, CVT continuously variable transmission, dual-clutch transmission, and automated manual transmission. Using an automatic transmission makes vehicle operation more convenient. The core function of an automatic transmission is to achieve automatic gear shifting, meaning that while driving, the driver operates the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on engine load and the vehicle's operating conditions.

What is the 80/100-10 tire compatible with?

80/100-10 tire is compatible with 90/90-10. The first 90 represents the section width, the second 90 represents the aspect ratio of 90 percent, "-" indicates a bias-ply tire, and 10 represents the rim diameter of 10 inches. A common tire expression is 205/55r16, where 205 is the tread width of 205 millimeters, 55 is the aspect ratio, and 16 means the tire can be mounted on a 16-inch rim. Tires are round, elastic rubber products assembled on various vehicles or machinery to roll on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance.

Is it still necessary to display the vehicle insurance decal?

It is still required to display the vehicle insurance decal. Compulsory Traffic Insurance (CTI) is a mandatory insurance for vehicles, and the insurance decal must be affixed to the upper right corner of the front windshield. However, starting from 2018, pilot areas in Beijing no longer require physical insurance decals on vehicles, replacing them with electronic insurance policies. Vehicles that have already obtained license plates and registration certificates must display the annual inspection decal. Annual vehicle inspections are a mandatory check-up conducted every year to ensure driver safety. These inspections help identify hidden hazards that are not usually visible and remind drivers to perform timely maintenance, enhancing safety awareness and protecting driving safety, thereby reducing the occurrence of traffic accidents.
