What does variable gear ratio steering in cars mean?

Variable gear ratio steering system refers to adjusting the steering ratio of the car's steering mechanism based on the vehicle's speed and steering angle. Below is relevant information: 1. When the car is driving at low speeds or with large steering angles, it provides a smaller steering ratio. When the car is driving at high speeds or with small steering angles, it provides a larger steering ratio to enhance the stability of the vehicle body. 2. Currently, there are mainly two types of variable gear ratio steering systems. One relies on a special rack to achieve the effect, with relatively simple working principles and lower production costs. The other method is more complex, utilizing planetary gear structures and electronic systems, resulting in higher production costs. Structurally, they can be divided into mechanical variable steering ratio systems and electronic variable steering ratio systems. 3. The naming of variable gear ratio steering systems varies among different car brands. For example, BMW calls it the AFS active steering system, Audi refers to it as the dynamic steering system, Toyota and Lexus name it the variable gear ratio steering system, and Mercedes-Benz calls it the direct steering system. Although their functions are similar, the production technologies used by each car manufacturer differ, with higher-end car brands generally having better-developed steering systems.

What is the difference between 5W30 and 10W40 motor oil?

The W in the motor oil grade stands for Winter. The number before W indicates the oil's low-temperature fluidity. The smaller the number, the better the low-temperature fluidity of the oil, making cold starts easier. The number after W represents the oil's high-temperature viscosity. The larger the number, the better the protection performance at high temperatures. The main differences between 5W30 and 10W40 motor oils are as follows: 1. Different applicable temperatures: 5W oil has a freezing point temperature of -30°C, while 10W oil has a freezing point temperature of -20°C. 5W30 oil has better cold resistance than 10W40, can be used at lower temperatures, and has better cold start performance. 2. Different oil viscosity: 30 and 40 indicate the high-temperature viscosity of the oil. 10W40 oil has higher viscosity than 5W30, providing better high-temperature protection and sealing performance. However, higher viscosity does not always mean better performance. Excessive viscosity can increase engine operating resistance, leading to insufficient engine power and increased fuel consumption.
