Background
The turbocharger utilizes waste gas generated during combustion of the engine to push the turbine so as to drive the compressor to rotate, thereby achieving the purpose of increasing the air input of the engine and the power of the engine. In order to meet the increasingly strict emission regulations and achieve the best emission effect, for a gasoline supercharged engine, it is always desirable to control the air-fuel ratio of the engine to the optimum exhaust gas conversion air-fuel ratio when closed-loop control conditions are met. However, as engine load and speed increase, the exhaust temperature may increase beyond or near the tolerance of the turbine if controlled at the optimum exhaust gas conversion air-fuel ratio at all times. The prior turbocharger cooling method mainly cools a volute and a turbocharger bearing, but the prior turbocharger cooling method can cause thermal damage to a turbine, so that the service life of the turbine is shortened.

Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, the turbocharger turbine inlet air cooling device provided by the utility model comprises an engine exhaust manifold interface 1, a compressor 2, a compressor outlet pipe 4, a turbine 5, a venturi tube 8, a compressor outlet pipe branch pipe 10, a check valve 11, a compressor casing 12 and a volute 13; wherein, the compressor 2 is arranged inside the compressor shell 12; the turbine 5 is arranged inside the volute 13, and the compressor 2 and the turbine 5 are coaxially arranged; one side of the compressor shell 12 is provided with a compressor air inlet 3; the inner end of the gas outlet pipe 4 of the compressor is communicated with the compressor shell 12; a turbine air outlet 7 is arranged on one side of the volute 13; the inner end of the Venturi tube 8 is connected with the turbine air inlet 6 on the volute 13, and the outer end of the Venturi tube 8 is a Venturi tube throat 9; the inner end of the engine exhaust manifold interface 1 is connected with the outer end of the venturi tube throat 9; one end of a compressor air outlet pipe branch pipe 10 is connected with a compressor air outlet pipe 4, and the other end is connected to the side surface of a venturi tube throat pipe 9; the one-way valve 11 is arranged on the compressor air outlet pipe 4, and the air flow flows from the compressor air outlet pipe 4 side to the venturi tube throat 9 side.
The check valve 11 is a pneumatic or electric check valve.
Will now the utility model provides a turbo charger turbine cooling device that admits air's theory of operation as follows:
in the working process of the turbocharger, waste gas flows into a Venturi tube 8 from an engine exhaust manifold interface 1 through a Venturi tube throat 9, then enters the inner part of a volute 13 through a turbine air inlet 6, then drives a turbine 5 and a coaxially arranged compressor 2 to rotate together, and then flows out through a turbine air outlet 7; meanwhile, air enters the interior of the compressor shell 12 through the compressor air inlet 3, is pressurized by the compressor 2, and then flows into the compressor air outlet pipe 4 to be discharged outwards. When the exhaust gas flows through the venturi throat 9, the pressure drops below the pressure in the compressor outlet duct 4 due to the increased flow velocity. When the temperature of the exhaust gas exceeds a set value, the one-way valve 11 is opened, and then the air flow in the compressor air outlet pipe 4 flows into the venturi tube throat 9 through the one-way valve 11, then flows into the upper part of the venturi tube 8, is mixed with the exhaust gas from the engine exhaust manifold interface 1, and then enters the interior of the volute 13 through the turbine air inlet 6. Because the temperature of the air flow in the air outlet pipe 4 of the compressor is far lower than that of the exhaust gas flow, the temperature of the exhaust gas at the inlet of the turbine can be reduced. The air flow passing through the valve can be controlled by adjusting the opening size of the valve on the one-way valve 11, so that the air-entraining quantity from the air compressor 2 can meet the requirement of the turbine 5 on air intake cooling, and the loss of the air intake quantity of the engine can be reduced as much as possible.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
