Storage type turbocharger

Abstract

The invention belongs to the technical field of turbochargers, and particularly relates to a storage type turbocharger. The turbocharger comprises a casing, an air intake turbine, an air exhausting turbine and a driving device; an air exhausting passage, an air intake passage and an air intake storage groove communicating with the air intake passage are formed in the casing; a front-side air intake passage and a back-side air intake passage are arranged on the air intake passage; a front-side air exhausting passage and a back-side air exhausting passage are arranged on the air exhausting passage; the air intake turbine is arranged in the air intake passage; the air exhausting turbine is arranged in the air exhausting passage; the air exhausting turbine is fixed axially; the air intake turbine and the air exhausting turbine rotate coaxially; and the driving device is used for driving the air intake turbine to slide between the air intake passage and the air intake storage groove. The turbocharger has the beneficial effects as follows: when the storage type turbocharger is not required to work, the driving device controls the air intake turbine to be stored in the air intake storagegroove, the condition that the flow velocity of an air intake flow is reduced due to the fact that the air intake flow is hindered by the air intake turbine is prevented, and the air intake efficiencyof an engine is increased.

Description

Technical field [0001] The invention belongs to the technical field of turbochargers, and in particular relates to a retractable turbocharger. Background technique [0002] Regardless of whether the turbocharger in the existing engine works, its intake and exhaust turbines are located in the corresponding air passages, which hinder the airflow in the corresponding air passages, especially the intake turbines in the intake passages. The intake air flow rate has a greater impact. When the engine is idling or the speed is lower than 1500r / min, the intake turbine cannot produce enough positive pressure on the intake, but the intake turbine is located in the intake duct, which will cause resistance to the already low intake airflow, making the intake air The flow rate is lower. Summary of the invention [0003] In order to solve the problem in the prior art that when the turbocharger does not need to function, the intake turbine is located in the intake duct to hinder the intake airf...
