Double-runner controllable turbocharger

Abstract

The double-runner controllable turbocharger comprises an installation shell, a double-runner air inlet mechanism and a filtering mechanism, the double-runner air inlet mechanism comprises a first connecting shell, a connecting rod is fixedly connected to the interior of the first connecting shell, a stabilizing block is fixedly connected to one end of the connecting rod, a connecting shaft is arranged in the stabilizing block, and the connecting shaft is fixedly connected to the other end of the connecting rod. One end of the connecting shaft is rotationally connected with an impeller. Due to the arrangement of the double-flow-channel air inlet mechanism, when high-temperature waste gas exhausted by an engine enters the double-flow-channel air inlet mechanism, the waste gas enters the supercharging chamber from the channels corresponding to the first flow channel pipe and the second flow channel pipe to impact the blades on the surface of the impeller, the double-flow-channel design is adopted, when the engine is at a low rotating speed, the gas displacement is relatively small, and the engine is more stable. However, the double-flow-channel structure can enable the waste gas to be more concentrated and impact the impeller more effectively, the problem that the turbine is difficult to quickly reach the ideal rotating speed due to insufficient waste gas flow and pressure is avoided, and the turbine delay phenomenon is greatly reduced.
