TermiNOx D

Engine Control Systems is proud to have the TermiNOx D, a urea-based selective catalytic reduction system on the National Clean Diesel Campaign’s Emerging Technology List. The Emerging Technology list is intended to provide guidance in selecting a technology for the Clean Diesel Emerging Technologies Program’s Request for Proposals.

The ECS Terminox D System is a retrofit SCR system for on-road heavy duty vehicles aimed at the reduction of NOx and hydrocarbon emissions. The technology used is called Selective Catalytic Reduction (SCR), in which urea is injected into the exhaust stream, which then decomposes to produce ammonia (NH3). When passing through the SCR catalyst, the ammonia reacts with the NOx to produce nitrogen (N2) and water (H2O).

TermiNOx D reduces nitrogen oxides (NOx) emissions from EGR and non-EGR equipped 4-stroke diesel engines manufactured between 1998 through 2006. The system consists of a Catalytic Muffler, Urea Dosing & Control unit, Urea Tank, Sensors, Dash Indicator Unit and Harness for easy installation and retrofit. The TermiNOx D reduces Particulate Matter (PM) by 25%, Carbon Monoxide (CO) by 85%, Hydrocarbons (HC) by 85% and Nitrogen Oxides (NOx) by 65%.

Emerging Technology List

The primary goal of the Emerging Technology program is to support early deployment of new technologies that will reduce diesel emissions from existing engines. The program provides an opportunity for manufacturers to obtain feedback from fleet partners on their technology while it is in-use. A technology may reside on the Emerging Technology List for one year from the effective date. During that year, the manufacturer will seek full verification. The verification process officially evaluates the emission performance of the technology. Once verified, EPA will list the official performance data and associated information on the National Clean Diesel Campaign’s Verified Technology List.
