AI Technical Summary
Technical Problem
Existing gas mixing devices struggle to effectively mix exhaust gas and cooling gas, particularly in applications where the exhaust gas has a higher flow velocity in the radially outer direction.
Method used
A gas mixing device with a cylindrical portion having a cooling gas inlet, exhaust gas inlet, and mixed gas outlet, featuring openings along its peripheral wall positioned differently in the axial direction, and incorporating a vortex generation suppression wall to enhance mixing efficiency.
Benefits of technology
The device efficiently mixes exhaust and cooling gases, preventing vortex formation and ensuring smooth discharge, thereby optimizing the operation of internal combustion engines.

Abstract
To provide a gas mixing device capable of effectively mixing exhaust gas and cooling gas. [Solution] The gas mixing device 10 mixes exhaust gas discharged from an internal combustion engine 26 with cooling gas introduced from outside the internal combustion engine. The gas mixing device comprises a cylindrical section 46 and a cooling gas inlet 50 for introducing cooling gas into a space 58 outside the cylindrical section. An exhaust gas inlet 52 is provided at one end of the cylindrical section, and a mixed gas outlet 54 is provided at the other end of the cylindrical section for discharging the mixed gas, which is a mixture of exhaust gas and cooling gas. Multiple openings 72 are formed in the peripheral wall 56 of the cylindrical section to allow the cooling gas in the space to flow into the inside of the cylindrical section, and the positions of the multiple openings in the axial direction of the cylindrical section are different from each other.
