Patent number: 11629625Abstract: Engine systems and methods use a dual air injection approach to control exhaust reactions and to maintain temperatures below a maximum limit of exhaust system components during engine enrichment operation conditions. Dual air injectors are disposed in the exhaust system with one upstream from, and another downstream from, the catalytic converter. Providing air injection before and/or after the converter helps convert all HC, CO, and PM emissions while keeping the catalyst temperature below the catalyst protection temperature limit. Air injection quantity may be controlled and diagnosed by monitoring the temperatures before and after the catalytic converter. The catalytic converter may be a three-way catalytic converter for lower cost or a downstream two-way catalytic converter may be added if further emission reduction is necessary.Type: GrantFiled: July 5, 2022Date of Patent: April 18, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATONS LLCInventors: Chengke Liu, Rafat F Hattar, John Michael Ellenberger, Philipp A Seyfried
