Abstract

The present invention relates to technology of increasing the air density and the air intake amount of turbo supercharging mechanism, and is especially one kind of water cooled intermediate shell turbo supercharging mechanism. The technological scheme is that one water cooled intermediate shell with mutually communicated water inlet hole and water returning hole is set between the air compressor vane wheel and turbine vane wheel on supercharger shaft, and water is made to enter into the water cooling passage inside the intermediate shell for heat exchange circulation. The present invention can increase the air density and the air intake amount to ensure complete combustion in the combustor of engine, increase engine power and reduce tail gas exhaust.

Description

technical field [0001] The invention relates to a technology for increasing the air density of a turbocharger mechanism and increasing the intake air volume, in particular to a water-cooled middle casing turbocharger mechanism. Due to the increase of intake air density, the intake air volume can be increased correspondingly, so that the combustion chamber of the engine can be burned more fully, so that the engine power can be increased and the emission of automobile exhaust can be reduced. Background technique [0002] In order to fully burn the fuel and reduce the discharge of exhaust pollutants in the existing multi-cylinder engines, methods such as improving the fuel system of the diesel engine such as the electronic control fuel injection system and the structure of the combustion chamber are generally adopted, but this will inevitably increase the cost of the engine. Customers bring too much economic expenditure; ordinary turbochargers only rely on air cooling for super...
