What does 4matic mean?

4matic refers to the 4ETS differential limiting technology, which is the core technology of Mercedes-Benz's 4MATIC four-wheel drive system. Below is a partial introduction to 4ETS: 1. Principle: 4ETS utilizes the automatic braking force distribution function of ABS to achieve differential limitation. Its characteristics include a compact and lightweight design, and it is applied to Mercedes-Benz sedans. 2. Function: 4MATIC enhances the active safety performance of the vehicle during high-speed driving. The 4ETS technology of 4MATIC can dynamically adjust the torque of each wheel from 0% to 100%, thereby optimizing the rational distribution of driving force and ensuring the active safety of the vehicle at high speeds. Additionally, it allows for higher cornering speeds and limits.

What is the function of a vacuum booster pump?

The relevant introduction of the vacuum booster pump is as follows: 1. Meaning and function of the booster pump: The automotive booster pump refers to a component that helps improve and stabilize the performance of a car. It mainly assists the driver in adjusting the direction of the car. Currently, most cars are equipped with booster pumps, mainly including steering booster pumps and brake vacuum booster pumps. 2. Classification of booster pumps: In the current market, power steering systems can be roughly divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. In mechanical hydraulic power steering systems, the amount of assistance is only related to the increment (angular velocity) of the steering wheel angle.

What is the main function of a car differential?

The main function of a car differential is to ensure that both driving wheels perform pure rolling motion. Below is an introduction to the differential: 1. Introduction: The car differential enables the left and right (or front and rear) driving wheels to rotate at different speeds. It mainly consists of left and right axle gears, two planetary gears, and a gear carrier. 2. Function: Its purpose is to allow the left and right wheels to roll at different speeds when the car is turning or driving on uneven road surfaces, ensuring that both driving wheels perform pure rolling motion. 3. Objective: The differential is designed to adjust the speed difference between the left and right wheels. In four-wheel drive systems, to drive all four wheels, they must be connected. If all four wheels were mechanically connected, the car would not be able to rotate at the same speed when driving on curves. To allow the car to maintain a relatively consistent rotational speed during curve driving, a center differential is added to adjust the speed difference between the front and rear wheels.

What Causes Abnormal Noise When Starting the Engine?

When starting the vehicle, the reasons for abnormal engine noise include: 1. Premature connection of the electromagnetic switch main contacts: The starter makes abnormal noise when the starter drive gear has not yet engaged with the flywheel ring gear. 2. Poor contact of the electromagnetic switch: The rotor collides with the magnetic pole, the brushes are excessively worn, or the electromagnetic switch has poor contact. 3. Drive gear failure to disengage: The drive gear fails to disengage and continues to operate. Even after turning off the ignition switch and cutting off the power, the starter still runs, and a screeching sound occurs immediately after the engine starts. The starter is dragged at high speed and cannot stop or takes a long time to stop, causing the starter to sweep and burn out.

How are trucks that fail the annual inspection usually handled when caught by traffic police?

Generally, a fine of 200 yuan will be imposed and 3 points will be deducted. Here are the relevant details: 1. Failing the inspection for 2 years: If a vehicle fails the annual inspection for more than 2 years, its vehicle record will be canceled. At this point, the vehicle will not be able to undergo the annual inspection procedure, and to restore its use, the vehicle record must first be reinstated. You need to apply at the vehicle management office, pay a substantial fine, and go through a cumbersome process to restore the record. 2. Failing the inspection for 3 inspection cycles: If a vehicle fails the annual inspection for more than 3 inspection cycles, the vehicle management office will enforce a mandatory scrapping process, and driving a scrapped vehicle will result in the revocation of the driver's license.

What is the emergency rescue number for highways?

The emergency rescue number for highways in most provinces across the country is 12122, with slight variations in different cities and provinces. Vehicle owners can dial 12122 for assistance in case of accidents or emergencies on the highway. In addition to the nationwide unified emergency number, different provinces may have their own specific service hotlines. Additional Information: 1. 12122 is the national highway emergency rescue number, which is completely non-profit and can only be used with approval from the Communications Administration. It is specifically for reporting emergency highway accidents. Additionally, 12328 is a supervision service number, while 122 is the accident reporting number. 2. In the event of a traffic accident, dial 122 to report the incident. The correct way to make the call is as follows: When dialing the traffic accident emergency number, remain calm and composed. After hearing the dial tone, dial 122. Once connected, confirm that you have reached 122 to avoid dialing the wrong number. Clearly state the location, position, and time of the accident, as well as key details such as casualties, to ensure a swift police response and timely medical assistance for the injured. Answer the dispatcher's questions calmly and provide your name and phone number to maintain contact.
