What are the internal parts of turbocharging parts?

First of all, about the structure of Turbocharger Accessories, exhaust turbocharger accessories are mainly composed of pump wheel and turbine, of course, there are some other control elements. The pump wheel and turbine are connected by a shaft, that is, the rotor. The exhaust gas from the engine drives the pump wheel, and the pump wheel drives the turbine to rotate. After the turbine rolls, it pressurizes the intake system. The supercharger is installed on the exhaust side of the engine, so the operating temperature of the turbocharger is very high, and the rotor speed of the turbocharger is very high, which can reach more than 100000 revolutions per minute. Such high speed and temperature make the common mechanical needle roller or ball bearing unable to work for the rotor. Therefore, the Turbocharger Accessories generally use full floating bearing, which is smoothed by oil, There is also coolant to cool the supercharger. Once, most Turbocharger Accessories were used in diesel engine, now some gasoline engine also choose turbocharger parts. Because the burning methods of gasoline and diesel are different, the selection of Turbocharger Accessories for the engine is also different.
Turbocharging is very simple, beyond the 1 bar boost value, for example, Golf R can reach 1.3. After cylinder reinforcement and computer tuning, many modified vehicles can easily achieve a high supercharging value of 1.5. For example, the original factory supercharging value of STI of the 10th generation cheetah is 0.9, and it can easily reach 1.5 after adjusting the engine computer. However, most of the household non functional vehicles we buy, such as golf 1.4T and regal 2.0T, are much lower than 1, generally between 0.3 and 0.5, which can balance the functions, fuel consumption and the life of the engine. It can be seen that the turbocharging is much higher than the supercharging value of the mechanical supercharging, and the corresponding engine power improvement is also greater.
Engineering supercharger, piston type aviation engine to add cylinder intake pressure equipment. The air before entering the engine cylinder is compressed by the supercharger to improve the air density, so that more air is filled into the cylinder, and then the power of the engine is increased. The engine equipped with supercharger can not only output more takeoff power, but also improve the altitude characteristics of the engine.
Marine supercharger: the so-called supercharging is to pre tighten the air before it is supplied into the cylinder, so as to improve the air density and add a skill of air intake. The intention is to add air volume, improve power, improve economy and emission.
The Turbocharger Accessories use the high-temperature exhaust gas of 700-900 ℃ from the engine to drive the turbine in the turbine to rotate. The turbine shaft drives the impeller in the compressor to rotate at a high speed. The air is compressed by centrifugation, and the inlet density of the engine is improved to 2-3 atmospheres. Then we can inject more fuel into the engine to improve the engine power.
The exhaust gas turbocharger is composed of a turbine driven by exhaust gas, a compressor for compressing fresh air, a center body with a bearing supporting function in the center and a bypass valve operating organization.
Supercharger shall refer to the air intake turbocharger of the engine, including three modes: exhaust turbocharger, mechanical turbocharger and electric auxiliary turbocharger. After the supercharger tightens the air, the intake density of the engine is improved, and then the power of the engine can be improved. At the same time, because the mixed incineration conditioning of the starter has been improved, the incineration power has been improved, and it can also save fuel and reduce emissions. It is an important skill improvement of modern initiators. Now the most widely used is the engine exhaust turbocharger. Let's explain in detail some common sense of the engine exhaust turbocharger.
