Please Service Power Steering indicates a power steering system malfunction. The causes of power steering failure include: 1. Excessive air in the power steering system; 2. Foreign objects in the steering hydraulic lines causing the steering pump flow control valve to stick; 3. Loose connections in the power steering system leading to steering fluid leakage; 4. Excessive wear of the steering gear piston cylinder, poor oil seal performance, or control valve sticking/damage. Power steering systems are classified into mechanical hydraulic power steering, electro-hydraulic power steering, and electric power steering. The principle of mechanical hydraulic power steering involves converting part of the engine's power output into hydraulic pump pressure to provide auxiliary force to the steering system, enabling tire rotation.

What is the Difference Between Leopard Super Select 4WD and Mechanical 4WD?

The following are the differences between Leopard Super Select 4WD and Mechanical 4WD: 1. Driving Force: The Super Select 4WD is an electronically assisted SS4-II system. The advantage of the Super Select 4WD system is that the vehicle can freely switch between 2H and 4H gears within a speed of 100 km/h. When in the 4H position, it achieves true full-time four-wheel drive, providing better traction and driving force. 2. Applicability: When in the 4HLC position, it is equivalent to the high-speed four-wheel drive of a hardcore part-time 4WD off-road vehicle, and the vehicle's central differential is locked at this time, with the front and rear axle power distribution maintained at 50:50 and constant output. It is suitable for unpaved roads such as sand and muddy paths. 3. Climbing: When in the 4LLC position, it is equivalent to the low-speed four-wheel drive of a hardcore part-time 4WD off-road vehicle, with the central differential also locked, and the front and rear axles each outputting 50% of the power. Additionally, the transfer case switches to a low-speed gear, which can amplify the torque by 1.9 times.

Is a Break-in Period Inspection Necessary for Mercedes-Benz?

It is highly recommended to conduct a break-in period inspection after purchasing a new car. Concept of the break-in period for new cars: The so-called break-in period for a new car refers to the initial driving period after the car leaves the factory, during which the engine components are allowed to wear in smoothly. The typical break-in mileage for a new car ranges from 1,000 to 3,000 kilometers. Characteristics of the break-in period for new cars: Higher incidence of driving faults: Due to factors such as improper assembly of components, new cars are more prone to driving faults during the break-in period; Increased fuel consumption: To ensure the new car operates under light load during the break-in period, carburetor-equipped cars are fitted with speed limiters, which can easily lead to an overly rich air-fuel mixture, thereby increasing fuel consumption; Lubricating oil is prone to deterioration: During the break-in period, the rough surfaces of components and the small gaps between them cause the lubricating oil temperature to rise. Additionally, many metal particles are worn off and mix into the lubricating oil, making it more susceptible to oxidation and deterioration.

Does the Tang DM have memory function for the rearview mirrors?

The Tang DM's rearview mirrors do not have a memory function. Features of the BYD Tang's rearview mirrors: The BYD Tang DM's rearview mirrors are divided into interior and exterior mirrors. The interior rearview mirror comes standard with an auto-dimming function across all models. The exterior rearview mirrors are equipped with electric heating for defrosting and an automatic folding function as standard. Additionally, the ZhiLian ChuangLing and ZhiLian ChuangShi versions also feature an automatic tilt-down function for the exterior mirrors when reversing and dual-curvature exterior mirrors. These features apply to the 2019 model year. BYD Tang DM: The newly added BSG motor in the Tang DM model is primarily used for faster and smoother engine starts and generally does not participate in power output. The vehicle's power is still provided by the original front/rear motors. The electric four-wheel-drive layout, with one motor each at the front and rear, remains unchanged, with the main upgrade being an enhancement to the rear motor's performance. This upgrade increases the maximum power by 70 kW and the maximum torque by 130 N·m. In terms of battery configuration, the Tang DM offers two options: 80 and 100. The Tang DM80 model has a total battery energy of 20kWh, providing a pure electric range of 80 kilometers.

What is the function of the brake wheel cylinder?

The brake wheel cylinder, also known as the hydraulic brake master cylinder, is the power source of the service brake system. The braking force comes from the pedal force applied by the driver on the brake pedal and the vacuum degree of the engine intake manifold (vacuum booster), with the vacuum degree being the main power source of the master cylinder. Here is relevant information about the brake wheel cylinder: 1. Function: The function of the brake wheel cylinder is to convert the hydraulic energy input from the brake master cylinder into mechanical energy to bring the brake into working condition. There are two types of brake wheel cylinders: single-piston and double-piston. The single-piston brake wheel cylinder is mainly used in double-leading shoe and double-trailing shoe brakes, while the double-piston brake wheel cylinder is more widely used and can be applied to leading-trailing shoe brakes, bidirectional double-leading shoe brakes, and bidirectional self-energizing brakes. 2. Classification: The clearance self-adjusting device is divided into one-time adjustment type and step type. The former automatically restores the clearance in the brake to a preset value after each braking, while the latter requires multiple braking actions to eliminate accumulated excessive clearance during braking or release. The excessive clearance of the brake is not entirely caused by the wear of the friction pair but also includes the thermal expansion of the brake drum and the clearance caused by the elastic deformation of the shoe and hub.
