What kind of power machine is a turbocharger？
If the oil seal at the turbine end of the turbocharger fails, the exhaust gas will enter the engine lubrication system through the sealing ring, and the oil will fail prematurely after a long time. In addition, when the engine is running at low speed, the oil will also enter the exhaust pipe through the sealing ring. The exhaust pipe is discharged and discharged, causing smoke from the exhaust pipe; if the oil seal at the compressor end fails, the oil in the turbocharger will enter the compressor casing, and be sucked into the cylinder together with the intake air for combustion, resulting in excessive oil consumption, resulting in the phenomenon of "burning oil", and in severe cases, it will also cause an increase in carbon deposits in the cylinder.
A turbocharger turbine is a rotating power machine that converts the energy of the flowing working medium into mechanical work. It is one of the main components of aero-engines, gas turbines and steam turbines.
The turbocharger takes the working principle of a gasoline engine as an example. For each kilogram of gasoline supplied to the cylinder, it takes about 15 kilograms of air to be sucked into the cylinder to ensure that the gasoline is fully burned. However, the volume of this 15 kg of air will be very large, and it is not easy to completely inhale such a large volume of air only by the vacuum generated by the cylinder during the intake process of the engine. Therefore, it is particularly important to improve the ability of the engine to inhale gas, that is, to improve the charging efficiency of the engine. There are two ways to increase the intake air volume of the engine. The first is the rear-stage turbocharging technology. In principle, the rear-stage turbocharging technology uses a special compressor to compress the gas before entering the cylinder to improve the gas entering the cylinder. Gas density, reducing the volume of the gas so that, per unit volume, the gas
The mass is greatly increased, and the intake air volume can meet the combustion needs of the fuel, thereby achieving the purpose of improving the engine power.
