According to GlobalData’s Technology Foresights, which uses over one million patents to analyze innovation intensity for the automotive industry, there are 300+ innovation areas that will shape the future of the industry.

Exhaust gas mixing device is a key innovation area in Hybrid Electric Vehicles

An exhaust gas mixing device is a system or mechanism that mixes exhaust gas and reducing agents (such as urea) to improve the performance of exhaust emission purifying systems. The mixing device can be in the form of a nozzle, a diffuser panel, a static mixer, or a multi-stage mixer, and is designed to promote mixing and improve the hydrolysis reaction of the reducing agent to reduce and purify NOx in exhaust gas.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 20+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of exhaust gas mixing device.
