Accomplished entrepreneur Levon Termendzhyan serves as the equity owner of Viscon USA and Viscon International, two companies focused on manufacturing and distributing the Viscon fuel additive around the world. Under Levon Termendzhyan’s leadership, this product has been approved for use by the U.S. government and certified by the California Air Resources Board (CARB) as a possible candidate for its 2015 mandate to reduce harmful emissions.

Dedicated to protecting the public from harmful air pollution, the CARB develops and maintains various programs, including its recent Real Emissions Assessment Logging (REAL) initiative. Created as part of the On-board Diagnostic (OBD) Regulations approved by the Board, REAL will help regulators better track greenhouse gas and smog-related emissions in the state’s vehicles. In doing so, this makes the identification of automobiles that produce excess emissions easier and moves California closer to its goal of meeting federal and state air-quality standards.

The OBD Regulations approved by the CARB apply to the use of OBD systems in vehicles. These mechanisms largely consist of software that detects malfunctions with an automobile’s emission control system. Once an issue is discovered, the driver is alerted by the OBD system via an indicator light. Information about the faulty equipment is also stored to promote fast repairs from technicians.

REAL would ask the OBD system to do more than this. It will gather data about nitrogen oxide (NOx) emissions in heavy- and medium-duty diesel vehicles starting in 2022 and collect fuel-consumption data that can characterize carbon dioxide (CO2) emissions on heavy-duty vehicles. This information can subsequently be retrieved with the use of a data reader or scan tool. The technology needed to do this already exists in the CARB’s Portable Emissions Measurement Systems (PEMS), so the program can be implemented without installing new equipment into vehicles.
