UEFA TV

Automatic transmission engine is UEFA TVthe most common type of engine in modern automobile production. Due to its simple operation, more and more automobile consumers choose automatic transmission models. Corresponding to it is the braking system, which is one of the most important safety devices of the car and the content that the driver must be familiar with. This article will analyze the operation mechanism of the automatic transmission engine and braking system in detail for you. I. Automatic transmission engine Automatic transmission engine is a power system with internal combustion engine as the core, which is composed of hydraulic drive system, transmission system, cooling system, emission system, ignition system, etc. Compared with manual transmission vehicles, drivers of automatic transmission vehicles only need to stop, forward, reverse, idle and other operations through the gear lever, without involving clutch, gear shifting and throttle adjustment and other processes.In this way, drivers can focus more on the observation of driving conditions and driving safety, thus improving the comfort and reliability of driving. II. The braking of the automatic transmission engine. During the operation of the automatic transmission engine, the braking system ensures its safety and plays a key role. The brake system is mainly composed of brake pads, discs, drums, brake fluids and other components. When the driver steps on the brake pedal, the brake fluid in the brake cavity is compressed, and the brake pads in the brake disc or brake drum come into contact with it, so that the vehicle slows down or stops. Of course, the brake system mentioned here is only applicable to braking when driving, and it is generally done through the handbrake when parking. In automatic transmission vehicles, disc brakes are generally used. When the driver steps on the brake pedal, the brake master pump obtains high-pressure liquid from the booster, through the brake pipe,Brake valves, etc. are transmitted to the brake components composed of brake discs and brake pads, so as to achieve the purpose of braking. After braking, the pressure reducing valve will generate a rapidly fluctuating speed signal, which is recognized by a device on the transmission. This signal tells the transmission that the speed must be recalculated and the torque output by the engine must be reduced to an appropriate speed. III. In addition to braking, the automatic transmission engine has another braking method, that is, engine braking. Engine braking is a way to use the cylinder pressure of the engine to slow down the vehicle, which can play a certain braking effect. In some driving situations, the strength of the engine brake can also be adjusted by adjusting the accelerator pedal. It should be noted that in the process of high-speed driving for a long time, too much engine systemIt is easy to cause engine overload and excessive speed. There is no problem in short-term use. It is recommended to use brakes mainly. IV. The use of automatic transmission engine and braking system. When driving an automatic transmission vehicle, it is necessary to fully master the use of the engine and braking system. First of all, drivers should be familiar with the vehicle's instruction manual and understand the characteristics and usage of the engine and braking system of the vehicle they are driving. Secondly, the wear of the brake pads should be checked before driving to ensure that the brakes are effective, while keeping the brake fluid level not lower than the lower limit. During the driving process, you should pay special attention to the road conditions, keep a safe distance, and try to avoid sudden braking. In a word, automatic transmission engines and braking systems are key components of automobiles. Mastering their principles and usage methods will help improve driving skills and safety awareness.
