Emerging Technologies
Actifilter SG
Engine Control Systems Limited (ECS) and NxtGen Emission Controls Inc. are pleased that the U.S. Environmental Protection Agency (EPA) has placed the Actifilter SG, an ECS diesel particulate filter (DPF) emissions reduction system that utilizes NxtGen’s patented syngas generator and Catalytic Solutions’ catalyst technology, on the National Clean Diesel’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.
Actifilter SG is an actively regenerating DPF system designed to reduce particulate matter (PM) for exhaust gas recirculation (EGR) and non-EGR equipped 4-stroke highway diesel engines manufactured from 1994 through 2006. Unlike other active DPF’s which employ fuel burners or diesel fuel injection, the Actifilter SG incorporates a syngas generator. The syngas generator delivers a stream of syngas (hydrogen and carbon monoxide), which readily oxidizes over an oxidation catalyst to create the heat necessary to reliably keep the DPF clean and working efficiently. The syngas generator performs seamlessly without operator intervention or vehicle use interruptions. The Actifilter SG system is designed for intra-city medium duty trucks and buses where the passive regeneration of a DPF is impeded by low exhaust temperatures caused by low vehicle speeds and frequent stops. The system is projected to reduce PM emissions by 90% and hydrocarbon and carbon monoxide emissions by 80%.
Actifilter SG fleet trials on urban buses and delivery trucks have currently accumulated more than 5,000 hours of combined service already which have included demonstration vehicles operating successfully through a Canadian winter. Funds for these fleet trials and a portion of the Actifilter SG development were provided by Cenovus Energy’s Environmental Opportunity Fund and Sustainable Development Technology Canada (STDC).
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.
