Eco-Friendly Removal and IoT-Based Monitoring of CO Emissions Released from Gasoline Engines Using a Novel Compact Nomex/Activated Carbon Sandwich Filter.

A novel cost-effective, rapid, and eco-friendly method was described for the removal of carbon dioxide (CO) from the gaseous emissions of gasoline engines. This involved the use of a sandwich filter (~10 cm diameter) made of a nonwoven poly (-phenylene isophthalamide) (Nomex) fabric loaded with a thin layer of activated carbon. The optimized filter, with an activated carbon mass of 2.
