Engine turbocharging (engine enhancement device: turbocharging system) - makes the power stronger With the continuous development of science and How to mitigate currency fluctuation risktechnology, the automobile industry is also constantly updating and innovating, in order to meet people's driving experience In continuous pursuit, automobile manufacturers are also constantly pushing out new and launching more automobile enhancement devices to make vehicle performance better and better. Among them, the turbocharging system, as one of the very important devices, has been widely used in different types of cars.This article will introduce relevant knowledge such as turbocharging system, its working principle and different types of turbocharging systems. I. What is a turbocharging system? Turbocharging system, referred to as turbocharging, is a device that uses exhaust emissions to drive the internal turbine to improve the output power and torque of the engine. It is a mechanical supercharging system, because it uses the kinetic energy generated by the engine exhaust, converts it into the kinetic energy of the turbine, and then transmits it to the engine intake. The working principle of the turbocharging system is to increase the intake pressure, so that more air and fuel are mixed, and the combustion in the cylinder produces stronger thrust to improve the output power and torque of the engine. II. The working principle of the turbocharging system. The core part of the turbocharging system is the turbine, which is like a smallThe fan is composed of small blades, and has mechanical bearings and turbine oil seal protection to avoid too much oil diversion into the turbine. The working principle of the system can be divided into two parts, namely the exhaust part and the pressure part. ( 1) The first part of the exhaust part of the turbocharging system is the exhaust part. When the engine is running, the exhaust gas produced is sent into the turbocharger by the exhaust manifold to push the rotor of the turbine to rotate. The faster the turbine rotates, the more exhaust gas flows through it, and the greater the force that drives the turbine rotor to rotate. ( 2) The second part of the compressed part of the turbocharging system is the compressed part. The air supercharged by the exhaust part is sent into the intake of the turbocharger. The air passes through the turbine to form high-pressure air, and then it is sent into the intake manifold through the outlet part of the supercharger, and then enters the engine for combustion, thus improving the output power of the engine.III. Different types of turbocharged systems. There are different types of turbocharged systems, which are mainly divided into single-turbocharged, twin-turbocharged, variable geometric turbocharged and oriented turbocharged. ( 1) Single-turbocharged single-turbocharged system is the most basic and common turbocharged system and the most widely used system. It has only one turbine and one supercharger, and the exhaust and pressure are performed on the same turbine, which is usually suitable for four-cylinder or six-cylinder engines. ( 2) Dual-turbocharging dual-turbocharging system refers to the system of engine exhaust airflow entering a group of independently operating turbochargers respectively, and then sending the supercharged air into the engine intake duct through two independent superchargers to increase power and torque, which can greatly improve the output capacity of the engine, usually applicable to eight-cylinder Engines and engines with higher displacement.(3) Variable geometric turbocharging Variable geometric turbocharging technology refers to the installation of a geometric structure of a variable angle on the blades of the supercharger, which is used to change the outlet area and angle of the turbine to maintain the equivelosmity of the turbine intake part, so that the supercharger can work better under different working conditions and improve the low speed of the turbine. The work efficiency and exhaust volume below. ( 4) The difference between the positive turbocharger and the traditional turbocharger is that the direction needs to change beyond the physical rotation speed by better flowing the compressed air and fuel mixture to the supercharger. FORWARD TURBOCHARGER IS A KIND OF GAS CHARGER, WHICH IS MORE USED IN GAS TURBINE ENGINES, AIRCRAFT, ROCKETS AND OTHER FIELDS. Conclusion: Turbocharging systems have become the mainstream of major automobile brands, which can not only improve the dynamics, reliability and fuel economy of the vehicle, but also bring a more comfortable driving experience.Although the turbocharging system is so important, we should pay attention to it in daily use to avoid unnecessary damage. At the same time, manufacturers are also constantly improving the technical level of turbocharging systems to bring drivers a better driving experience.
