Are Seat Heating and Ventilation Functions the Same?

Seat heating and ventilation functions are not the same. Below are the relevant introductions about seat heating and ventilation functions: 1. Seat Heating: Seat heating refers to the electric heating device inside the seat, which is further divided into front seat heating and rear seat heating. Front seat heating is generally found in vehicles equipped with leather seats. The surface material of leather seats tends to be cold in winter, and most electric heating devices come with adjustable temperature functions. Rear seat heating is usually equipped in luxury cars or high-end models, such as the Mercedes-Benz S-Class, BMW 7 Series, Audi A8, etc. 2. Seat Ventilation: This is the 'summer cooling device' of car seat air conditioning. Although automatic air conditioning can maintain a constant temperature inside the car during summer, the close contact between the passenger's body and the seat restricts air circulation in the contact area, making it difficult for sweat to evaporate and causing discomfort. The unique ventilation circulation system of seat ventilation continuously delivers fresh air through small holes in the seat cushion and backrest, preventing sweat accumulation on the buttocks and back, and providing a comfortable riding environment. This effectively improves the air circulation in the contact area between the human body and the seat surface. Even after prolonged sitting, the contact area between the body and the seat remains dry and comfortable.

What is Power Steering?

Power steering system is a device that utilizes the engine's power to assist the driver in steering operations. It converts the engine's energy into hydraulic energy (electrical or pneumatic energy), and then transforms this hydraulic energy (electrical or pneumatic energy) into mechanical energy applied to the steering wheels to aid the driver in steering. Therefore, it should be referred to as a power-assisted steering system. Initially, it was primarily installed in vehicles to reduce the steering force required from the driver on the steering wheel. Below is an introduction to the power steering system: 1. Steering systems are divided into two categories: mechanical steering systems and power steering systems. The mechanical steering system consists of three main components: the steering control mechanism, the steering gear, and the steering linkage mechanism. It relies solely on the driver's physical strength as the steering energy source, with all force-transmitting components being mechanical. 2. The power steering system combines both the driver's physical strength and the engine's power as steering energy sources. Under normal circumstances, only a small portion of the energy required for vehicle steering is provided by the driver, while the majority is supplied by the engine through the power steering device. However, in the event of a power steering device failure, the driver should generally still be able to independently handle the vehicle's steering tasks. Therefore, the power steering system is formed by adding a set of power steering devices to the mechanical steering system.

What Causes the Sizzling Sound in a Car?

Here are the main reasons for the sizzling sound: 1. Foreign objects inside the tire: Most abnormal noises during driving come from the tires. If there are foreign objects in the tire, the noise will be very noticeable; 2. Suspension noise; 3. Noise from the vehicle itself: If any fixed components in the vehicle become loose, the most direct effect is the generation of abnormal noise. Additional information: The main reasons for the clunking sound in a car are: 1. Sound from the turn signal reset: When turning, the turn signal is used, and the reset of the turn signal is accompanied by a sound, which is normal; 2. Friction between plastic parts: Most components on the steering wheel are made of plastic, so when the temperature drops, the friction noise between these components will gradually increase; 3. Noise caused by aging of the steering tie rod ball joint: If this aging phenomenon occurs in the steering wheel, it is recommended to replace the steering tie rod ball joint in a timely manner and perform a wheel alignment operation on all four wheels after replacement.

Why Does the Low-Pressure Pipe of a Car's Air Conditioner Freeze?

The reason for the low-pressure pipe of a car's air conditioner freezing is due to a malfunctioning expansion valve or a failed evaporator temperature sensor. Below are the related explanations for the faults: 1. Malfunctioning Expansion Valve: The low-pressure pipe of a car's air conditioner freezing is most likely caused by a malfunctioning expansion valve, which fails to sense the real-time temperature of the low-pressure pipe. If the temperature is too low, the low-pressure pipe will inevitably freeze (the expansion valve's opening cannot be adjusted lower). This issue is generally irreparable, and a new expansion valve needs to be replaced. 2. Failed Evaporator Temperature Sensor: It may be due to a failed evaporator temperature sensor. This component is designed to detect the surface temperature of the evaporator and transmit the data to the automatic air conditioning control unit. When the temperature drops below 2°C, the air conditioner will stop operating to prevent frost or ice formation. If the evaporator temperature sensor fails, it naturally cannot detect the corresponding temperature data, leading to the low-pressure pipe freezing. In this case, a new sensor needs to be replaced.
