Problems solved by technology

There are large differences in the exhaust temperature, flow velocity and pressure of the two airflows, and they are violently mixed in the exhaust duct 22 of the turbine casing, which is close to the turbine, resulting in unstable flow of the airflow, resulting in airflow loss, reducing the efficiency of the turbine, and is not conducive to the engine Improved economy, at the same time the unstable flow of the airflow also creates noise problems

Abstract

The invention discloses an integrated waste gas bypass turbo machine with an airflow management device at the turbine end. The integrated waste gas bypass turbo machine comprises a turbine shell, a bypass waste gas channel and a turbine waste gas channel, as well as an integrated turbine shell cover plate which is arranged at the air outlet end of the turbine shell; both the bypass waste gas channel and the turbine waste gas channel extend from the turbine shell to the integrated turbine shell cover plate; and flow guide grooves are formed in the integrated turbine shell cover plate, the bypass waste gas channel and the turbine waste gas channel communicate with each other through the flow guide grooves, and the flow guide grooves are formed in the position, away from a turbine, of the integrated turbine shell cover plate. According to the integrated waste gas bypass turbo machine with the airflow management device at the turbine end, the bypass waste gas and the waste gas entering theturbine are naturally mixed in an exhaust passage which is far away from the turbine, and the impact is relatively small when the two strands of airflow are converged; and the advantages of being small in airflow loss, low in noise, high in turbo machine efficiency and the like are achieved.

Description

technical field [0001] The invention relates to a turbine on a turbocharger, in particular to an integrated waste gas bypass turbine with an airflow management device at the vortex end, and belongs to the field of internal combustion engines. Background technique [0002] The speed range of the vehicle engine is wide, and the supercharger is required to have good responsiveness, high torque at medium and low speeds, high torque reserve coefficient, and high rated power. In order to realize the matching of all working conditions of vehicle engines, wastegate turbochargers are generally used in vehicle engines. [0003] To meet these requirements, the wastegate turbocharger is designed with a turbine with a smaller flow capacity and a smaller compressor to increase the boost pressure and intake air flow in the low-speed section to meet the low- and medium-speed torque characteristics, smoke emission and response. sexual issues. Due to the design of a turbine with a small flo...
