Manual-automatic transmission AT refers to automatic shifting or automatic gear changing. Its working principle involves installing two turbine blades in a space filled with hydraulic oil, which are connected to the power input and output ends respectively. The powerful vortex generated by the impeller at the power input end drives the impeller at the output end to achieve power transmission. The core of the automatic transmission lies in achieving automatic gear shifting. Automatic gear shifting means that while the car is in motion, the driver operates the accelerator pedal as needed during the driving process, and the automatic transmission can automatically shift into different gears based on the engine load and the vehicle's operating conditions.

Is it normal for a car to leak water when the air conditioning is on?

It is normal for a car to leak water when the air conditioning is on. This water is the condensate from the air conditioning system. When the air conditioning is cooling, the temperature of the evaporator and the air ducts leading to the passenger compartment is very low. The water vapor in the outside air will liquefy and condense on the walls of the air conditioning pipes and housing at such low temperatures. If there is no way to drain it, it can cause dampness around the air conditioning system and corrosion of components. When designing a vehicle, pipelines are reserved to collect and drain the condensate. The outlet to the outside of the car is usually located directly below the center of the dashboard, which, when projected to the underside of the car, is basically at the front of the transmission. Therefore, in summer, if you start the engine, turn on the air conditioning, and leave the car parked for a while before driving away, you will often see a puddle of water on the ground. This puddle is actually the result of water vapor in the air condensing due to the cold, which is a normal phenomenon.

Is Installing Shock Absorber Buffers Useful?

Automotive shock absorber buffers are generally made of rubber materials. Like shock absorbers and suspension springs, they can assist in providing shock absorption and cushioning effects. During the operation of the shock absorber, the impact generated by the road surface is converted into the repeated bouncing motion of the spring by the suspension spring. Simultaneously, the shock absorber refines and accelerates the attenuation of the spring's inherent vibrations, with the final cushioning transmitted to the vehicle body via the shock absorber top buffer. Below is an introduction to shock absorber buffers: 1. Principle of Shock Absorber Buffers: They feature a spiral rubber design and are installed in the middle of the suspension spring. When the car corners and the center of gravity shifts to one side, causing the vehicle body to tilt and compress the spring, the buffer provides support, thereby reducing the car's body roll. 2. Overview of Shock Absorber Buffers: The buffer is a highly elastic and durable rubber product, classified as an automotive modification accessory. It is installed at the spiral spring of the car's suspension system, primarily serving to cushion shocks and protect the shock absorbers.

When will I receive the SMS notification for the Subject 2 driving test appointment?

Generally, the result of a Subject 2 driving test appointment will be known within 5 working days. Due to differences in the efficiency of relevant departments and the number of candidates in various regions, there is no precise standard for the timing of SMS notifications regarding appointment results. Therefore, it is also possible to receive an SMS notification approximately three days before the test. Below is more information about the Subject 2 driving test: 1. Introduction: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and is the abbreviation for the field driving skills test. 2. Test Items: The test items include reversing into a parking space, stopping and starting on a slope, turning at a right angle, driving along a curve, and parallel parking. In cities like Shanghai, Subject 2 consists of nine mandatory test items: reversing into a parking space, turning at a right angle, parallel parking, driving through a tunnel, stopping to take a card, driving along a curve, making a U-turn on a narrow road, emergency stopping, and stopping and starting on a slope.

How to Turn on the High Beam on a Mercedes-Benz GLE?

The high beam switch for Mercedes-Benz is located below the steering wheel, with the left lever serving as the light control lever. By rotating the left knob once, you can turn on the parking lights; rotating it twice activates the low beams. To turn on the high beams, simply pull the light control lever backward once.

Are There Subsidies for Imported New Energy Vehicles?

Imported new energy vehicles do not qualify for subsidies; only domestic models, including those from independent and joint-venture brands, are eligible. New energy vehicles included in the central government's subsidy program must meet specific requirements for pure electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles. Subsidies for new energy vehicles consist of national and local subsidies. More details are as follows: 1. National Subsidy. Firstly, the subsidy applies to new energy vehicles that meet the central government's criteria, specifically pure electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles that fulfill the requirements. Secondly, the national subsidy is not allocated to automakers or dealers but is directly provided to consumers. When purchasing a new energy vehicle, consumers pay the sales price minus the subsidy. It's important to note that the subsidy standard decreases annually, primarily due to considerations like economies of scale and technological advancements. 2. Local Subsidy. Local governments are tasked with implementing the national initiative to promote new energy vehicles. This was further emphasized in the "Notice on Continuing the Promotion and Application of New Energy Vehicles" issued in September 2013, which specifically called for immediate action from demonstration regions, such as the Beijing-Tianjin-Hebei area, Yangtze River Delta, and Pearl River Delta, where particulate matter pollution control is a significant challenge.
