Title: **Evan S Guy: Innovator in Gas Compression and Emissions Reduction**

Introduction

Evan S Guy, based in Helotes, TX, is a notable inventor with a focus on advancements in gas compression and emissions reduction. With a total of five patents to his name, Guy has contributed significantly to the field of environmental sustainability and innovation in internal combustion engine technology.

Latest Patents

Among his latest inventions is a **System of gas compression utilizing variable input pressures to produce a consistent output pressure**. This innovative system addresses the issue of fugitive natural gas emissions by enabling the reintroduction of gas in an unchanged and undiluted state into pressurized gas pipeline systems. By utilizing leakage from natural gas compressor piston rod packing seals and blowdowns during maintenance or emergencies, this system transforms practices within the natural gas pipeline industry, which traditionally vented or flared emissions.

Another impressive patent is the **Method and apparatus for reducing emissions of internal combustion engines**. This method involves the strategic introduction of secondary air into the combustion chamber after the main combustion event. It aims to significantly reduce hydrocarbon (HC) and carbon monoxide (CO) emissions, particularly in “rich burn” utility engines operating at an equivalence ratio of about 1.2 or above. The process capitalizes on the engine’s existing design to enable a secondary reaction that dramatically lowers emissions while maintaining low levels of nitrogen oxides (NOx).
