EPS stands for Electric Power Steering system, which represents the development direction of automotive steering systems. The role of EPS is to independently apply braking to individual wheels and participate in engine system management when the vehicle shows signs of instability, ensuring driving safety. EPS mainly consists of a torque sensor, vehicle speed sensor, electric motor, reduction mechanism, and electronic control unit. Below are the advantages of the EPS system: 1. The motor provides assistance only during steering, which can significantly reduce fuel consumption. 2. The steering assistance level can be adjusted via software, balancing steering ease at low speeds with handling stability at high speeds, while maintaining good return-to-center performance. 3. The steering gear operates with minimal noise, making steering more effortless.

Hey, EPS in cars stands for Electric Power Steering. I've driven vehicles equipped with this feature, and the steering wheel feels exceptionally light and effortless, especially during low-speed parking or turning maneuvers where single-handed operation is possible—unlike the old hydraulic systems that required more effort. EPS relies on an electric motor to provide steering assistance, which reduces engine load and consequently lowers fuel consumption during driving. In daily use, the system responds quickly and intelligently adapts to various road conditions. If any issues arise, such as a loss of power assistance, a warning light will appear on the dashboard, prompting immediate inspection of the wiring or motor components.

Should You Worry About Minor Scratches on a New Car?

No need to worry, it's quite normal for beginners to have minor scratches while driving. Just be cautious while driving. Here are some precautions for novice drivers: 1. Speed: As long as you're not on the highway, you can maintain a steady speed of around 60 km/h, which helps with control. 2. Observe the rearview mirrors: The rearview mirrors allow you to monitor the road conditions on both sides and behind the vehicle, especially when changing lanes, reversing, or overtaking. Their role is crucial. 3. Maintain a safe distance: Following too closely can be dangerous if the car in front brakes suddenly or cuts in. Sometimes, excessive tension may cause you to turn the steering wheel too sharply, leading to an accident. Therefore, keeping a safe distance from the car ahead is essential. If a car cuts in, slow down appropriately to yield. 4. Proper use of lights: Do not turn on the hazard lights randomly. Turn on the parking lights at dusk, and fog lights should only be used in foggy conditions with poor visibility.

Does the throttle need cleaning?

The throttle needs cleaning. The throttle is a controllable valve that regulates the air entering the engine. Since the air contains dust and sand particles, impurities are left on the throttle surface as air passes through. Combined with the oil vapor from the crankcase, this forms a black, greasy deposit layer. A dirty throttle can cause inflexible movement of the throttle valve, allowing impurities to enter the engine and affecting normal gasoline combustion. The throttle should be cleaned every 20,000 to 40,000 kilometers. If the driving environment is harsh, the cleaning interval should be shorter. However, excessive cleaning can lead to premature throttle failure, as frequent cleaning gradually removes the special coating inside the throttle chamber, making it more prone to grease buildup and creating a vicious cycle, ultimately resulting in the throttle's failure.

Where is the rearview mirror switch for the Buick GL8?

Buick GL8's heated rearview mirror shares the same button with the rear window defroster. Press it to activate the heating function for the rearview mirrors. The rearview mirror adjustment for the Buick GL8 is located on the door armrest. Before adjusting the up and down mirrors, you need to press the up and down mirror adjustment button first, then you can adjust the mirrors left, right, up, or down. Here are the methods for accurately adjusting the angles of the rearview mirrors: 1. Central rearview mirror Adjust the central rearview mirror so that it is parallel to the horizon, with the horizon positioned at the center of the mirror, occupying 1/2 of the mirror's surface. To ensure a clear view of the road behind, the mirror can be slightly tilted towards the driver. 2. Left rearview mirror Since the driver's seat is on the left, adjusting the left rearview mirror is particularly important. It is recommended to adjust the car's image to occupy 1/4 of the mirror's surface, with the horizon occupying 1/2. This adjustment ensures that you can see the following car's position behind you in the mirror, as well as vehicles in other lanes, aiding in driving judgment. 3. Right rearview mirror Due to its position on the right, the driver's blind spot is larger, so the adjustment angle differs from the left rearview mirror. Keep the car's image at 1/4 of the mirror's surface, but adjust the horizon's proportion to occupy 2/3 of the mirror's surface.

Is it necessary to add fuel cleaner?

It is necessary to add fuel cleaner. Here are the specific reasons for adding fuel cleaner: 1. Currently, fuel cleaner is also known as fuel additive. Fuel additive is a commonly used gasoline additive; 2. It is designed to compensate for certain deficiencies in gasoline, endowing gasoline with new and excellent characteristics, such as cleaning system carbon deposits, increasing octane value, improving atomization, reducing wear, and protecting the engine; 3. However, for new cars, it is not recommended to add fuel cleaner to allow parts and components, especially the engine, to grind to the optimal state. Using normal fuel directly can grind the vehicle to the best condition.

The 1.6-liter naturally aspirated engine delivers 128 horsepower and a maximum torque of 168 Nm. This engine features multi-point fuel injection technology and utilizes an aluminum alloy cylinder head and block. It is paired with a 5-speed manual transmission. The 1.5-liter turbocharged engine produces 178 horsepower and a maximum torque of 265 Nm. This engine incorporates direct fuel injection technology and also uses an aluminum alloy cylinder head and block. It is matched with either a 6-speed manual transmission or a 7-speed dual-clutch transmission. The dual-clutch transmission enhances gear shifting speed and transmission efficiency. One clutch in the dual-clutch system controls the odd-numbered gears, while the other manages the even-numbered gears. 2. The Changan Oushang Kosai employs a MacPherson independent suspension at the front and a torsion beam non-independent suspension at the rear. The use of a torsion beam rear suspension helps to maximize rear passenger space and trunk capacity.
