2010-Present
In 2008, CCC was invited to head up a research program funded by the California Air Resources Board (CARB). For three years, CCC provided products, personnel, and testing for the project. This research uncovered specific requirements to effectively control, over an extended time, emissions reduction for Natural Gas Engines.

The project with CARB concluded in 2012 with a long list of significant findings necessary to reduce emissions on large gas engines. These concepts included, more complete mixing of air and fuel, use of higher quality oxygen and NOx sensors in the control, the use of fast and accurate pressure control valves for varying AFR mix, venturis designed to create a proportional mix of fuel to air and many other advanced control concepts.

CCC’s new emissions control systems would be widely adapted for use on engines trying to meet rigorous emissions compliance requirements. In areas and states with very low emissions requirements, CCC’s products were often the only ones that could meet the more strenuous requirements.

By 2016, CCC expanded its control product line to include very precise measurement of natural gas in a small package which included a venturi for a true mass flow calculation. The FM50 was the right product at the right time and has become widely adopted by gas utilities and pipelines for measuring fuel consumption on their individual engines and turbines.

About the same time, CCC introduced the Cat Monitor products, which interfaces with the O2 and NOx sensors and communicates the data to the ECV5 to provide a complete AFR system. It also monitors and stores data related to the health and operation of the Three Way Catalyst used to eliminate most emissions: NOx, CO, and non-methane hydrocarbons.
