Abstract

The invention discloses a turbine box waste gas bypass device. The turbine box waste gas bypass device comprises a valve body, a connecting rod, a gasket and a lining, wherein the lining is embedded in a valve seat of a turbine box, the inner center of the lining comprises a waste gas channel, and the waste gas channel of the lining is communicated with a waste gas channel of the turbine box; the valve body is installed on the valve seat of the turbine box, and the end face of the lower end of the valve body is attached to the end face of the upper end of the lining in a contact manner; and the connecting rod is installed on the valve body through the gasket, and the connecting rod drives the valve body to rotate in the axial direction. Therefore, the spiral flow characteristic is given to bypass waste gas flowing through the lining, the waste gas bypass capacity of a turbocharger is improved, vibration noise caused by impact of the bypass waste gas on the valve body is reduced, and the turbine efficiency of the waste gas turbocharger is effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the field of turbochargers, and in particular, to a turbine box waste gas bypass device. Background technique [0002] At present, automobiles are generally equipped with turbochargers to improve the performance of automobile engines, such as increasing the power density of the engine, reducing exhaust emissions, and solving the problem of vehicle power shortage. The exhaust gas turbocharger is a kind of turbocharger, which uses the high-temperature and high-speed exhaust gas discharged from the vehicle engine to drive the turbine of the turbocharger to provide sufficient air for the engine. The higher the flow rate of exhaust gas through the exhaust gas turbocharger, the faster the speed of the turbine in the exhaust gas turbocharger. The flow rate of the exhaust gas discharged by the engine is often greater than the demand of the exhaust gas turbocharger, so a waste gas bypass structure is added t...
