General Information
Company: Woodward Inc.
Country of Origin: United States
Patent Title: High-Efficiency Exhaust Gas Return System
Patent Publication Number: CN116670385B
Filing Date: October 2021
Authority: China National Intellectual Property Administration (CNIPA)
Technology Overview
The patented system is designed to improve the efficiency of exhaust gas recirculation (EGR) by optimizing the return flow of exhaust gases within combustion systems. EGR technology is widely used in internal combustion engines and industrial power equipment to reduce nitrogen oxide (NOx) emissions and improve overall fuel efficiency.
By enhancing gas return efficiency, Woodward’s system aims to support more stable combustion control while reducing energy losses and emissions. Such improvements are particularly relevant for applications in gas turbines, large engines, and distributed power systems.
Industry Significance
Exhaust gas management remains a critical focus area in industrial automation and energy systems, especially as global emissions regulations become increasingly strict. Innovations like this patent demonstrate how control system providers are advancing hardware-level solutions to complement digital optimization strategies.
Woodward’s continued investment in combustion efficiency technologies aligns with broader industry trends toward decarbonization, regulatory compliance, and improved operational performance across energy and transportation sectors.
