EPS on a car stands for Electric Power Steering system, which uses the power generated by an electric motor to assist the driver in steering. The structural components of EPS vary depending on the vehicle. Relevant information about EPS is as follows: 1. Composition: It generally consists of a torque sensor, electronic control unit, motor, reducer, mechanical steering gear, and battery power source. 2. Function: When a car is subjected to lateral and longitudinal forces during driving, excessive lateral force can significantly reduce the steering force, making it easy to lose control. EPS, based on CPU calculations when the vehicle shows unstable tendencies, can independently apply braking to each wheel and participate in the management of the engine system to ensure driving safety.

I've driven several cars before and noticed significant differences in steering feel, only later realizing that EPS plays a crucial role. EPS stands for Electric Power Steering, essentially adding an electric assistant to your steering wheel. The old hydraulic power steering required the engine to drive an oil pump, which was fuel-consuming and cumbersome, while EPS directly uses an electric motor to drive the gear mechanism. The most noticeable difference is how light the steering feels at low speeds, like when reversing into a parking spot—even women can operate the wheel with one hand. At high speeds, the steering automatically becomes heavier to prevent the car from feeling unstable. Plus, it's more fuel-efficient than hydraulic systems, simpler in structure, and less prone to oil leaks. However, I should mention that if the steering suddenly feels heavy after driving through water, it might be due to the motor getting damp, and you should get it checked immediately. Overall, this system makes driving both easier and safer.

What does the one-kick function in cars mean?

One-kick function in cars means that when your hands are not free to open the trunk, you can sweep your foot under the rear bumper to open it. Here are some tips for using the one-kick function: Keep the key on you: The key should be located near the rear of the car, preferably on your person. Maintain a distance of at least 300mm: When performing the kicking motion, stand at least 300mm away from the vehicle. If you touch the rear bumper or move too slowly, this function may not work. Perform a back-and-forth motion: You must make a back-and-forth kicking motion toward the vehicle to successfully activate it. The one-kick feature is now available in many mid-to-high-end car models and can be very useful in certain situations. It is believed that this feature will become more widespread in the near future.

How spacious is the rear seating area of the Audi e-tron?

The Audi e-tron offers a rear longitudinal space of 860mm, which is quite impressive, providing a very spacious rear seating experience. Audi e-tron exterior: The e-tron features a very streamlined body design. Although it doesn't have an exaggerated fastback shape, its smooth lines give it an ultra-low drag coefficient of just 0.28Cd. The digital exterior mirrors were canceled due to Chinese regulations and replaced with conventional ones, slightly reducing its distinctive appearance. Audi e-tron interior: The interior design of the Audi e-tron still focuses on allowing users to operate it easily without much adaptation. The fully digital instrument panel, combined with the upper and lower high-quality screens on the center console, is a hardware configuration that can also be seen in other Audi models, but it seems to fit even more naturally in this pure electric vehicle.

What Does Engine Oil Viscosity Mean?

Engine oil viscosity is a measure of the thickness of a liquid or its resistance to flow. Engine oil, also known as engine lubricant, consists of: 1. Base oil: The main component of lubricating oil, determining its fundamental properties; 2. Additives: These compensate for and improve deficiencies in the base oil's performance. The effects of excessively low engine oil viscosity include: 1. Poor engine lubrication, increasing wear on piston rings and cylinder walls, reducing sealing performance, leading to oil burning; 2. Poor sealing performance of valve seals and damage to the crankcase forced ventilation valve; 3. Blockage of the crankcase ventilation port, causing excessive pressure inside the crankcase; 4. Inability of the oil to form a stable oil film on the surfaces of various engine components, resulting in the sudden generation of a large amount of heat within the engine.

How Many Airbags Does an Audi Have?

Audi is equipped with six airbags: two for the driver and front passenger, and two side airbags each for the front and rear rows. Function of Airbags: To prevent injuries caused by collisions between occupants and interior components during a car crash, serving as a supplementary safety device to seat belts, with both working in tandem. Protection Principle of Airbags: When a car experiences a certain level of impact force, the airbag system triggers a chemical reaction similar to the detonation of a small amount of explosive. The hidden airbags inside the car inflate and deploy instantly, positioning themselves in time before occupants collide with interior components. Upon contact with the airbag, the airbag begins to deflate through holes on its surface, thereby cushioning the impact and reducing the force exerted on the body, ultimately minimizing occupant injuries.
