Abstract

The invention relates to a turbine end structure for a turbocharger. A volute of the turbine end structure is provided with a turbine inlet channel, a turbine exhaust outlet, a volute exhaust outlet and a turbine rear pipeline. The turbine inlet channel is used for being connected with an engine exhaust manifold. A volute bypass gas channel is arranged between the turbine inlet channel and the turbine rear pipeline and internally provided with a bypass valve system. According to the turbine end structure for the turbocharger, the volute and the turbine rear pipeline are integrated, the problem that integration of an existing bypass valve system of an existing integrated volute is difficult is solved, and the space requirement of the turbocharger is better met; and besides, gas at a turbocharger volute outlet is rectified through an external rectiblock, and the whole performance of a turbocharger system is improved. The turbine end structure for the turbocharger is suitable for the application occasion with particular limit to the space of the turbocharger, including but not limited to a two-stage turbocharger.

Description

technical field [0001] The invention relates to a scroll end structure for a turbocharger, in particular to a scroll end structure that integrates a traditional turbocharger volute and a post-vortex pipeline, and is suitable for turbocharger Space-constrained applications including, but not limited to, two-stage turbochargers. Background technique [0002] With the update of engine technology, the requirements for turbochargers are getting higher and higher. On the one hand, the space occupied by the turbocharger is required to be small, and on the other hand, the turbocharger is required to have higher performance. [0003] In some special turbocharger applications, the exhaust gas outlet is required to be turned in a small space, and the traditional method of connecting the turbocharger volute outlet to the post-vortex pipeline has some shortcomings, such as the number of system components More, the required engine installation space is larger, and there is more risk of p...
