If the oil seal at the turbine end of a turbocharger fails, the exhaust gas will enter the automobile engine lubricating management system through the analysis of the sealing ring, and the oil will fail prematurely with the passage of social time; In addition, when the engine develops low speed operation, oil will also enter the exhaust pipe and exhaust from the exhaust pipe by studying the sealing ring, resulting in no smoke produced in the exhaust pipe; If the oil seal at the end of the compressor fails, the oil in the turbocharger will flow into the compressor housing of the enterprise and be sucked into the cylinder for combustion together with the intake air, resulting in that part of the oil can not be consumed excessively, resulting in "oil burning" phenomenon, and even more carbon deposition in the cylinder.

Turbocharger is a kind of rotating power engineering machinery that converts the energy of flow as working medium into output mechanical work. It is one of the main components of aeroengine, gas turbine and steam turbine.

According to the working principle of the gasoline engine, the turbocharger can supply 1 kg of gasoline for each cylinder, and about 15 kg of air needs to be inhaled for each cylinder to ensure the full combustion of gasoline. However, the volume of the 15kg air will be very large, and it will not be easy to draw such a large volume of air into the engine simply by virtue of the vacuum generated by the cylinder during the intake process of the engine. Therefore, it is very important to improve the ability of the management work engine to inhale gas, that is, we can effectively improve the inflation efficiency of our automobile engine.

There are two ways to continuously increase the intake volume of the engine. One is the post-stage turbocharging system technology. In principle, the development of the post-stage turbocharging technology is that before the gas enters the cylinder for data compression, we use a special compressor to pre-design the gas to improve the gas density of the students entering the cylinder, reduce the gas volume, and improve the gas quality within the unit volume, The intake volume is obtained to meet the needs of fuel combustion itself, thus effectively increasing the power of vehicle engine.
