Development of a Self Regenerating Particulate Trap for Diesel Emission Control(ST9165-1)

Environmental Energy Technologies, Inc


Uncontrolled emissions from diesel engines, such as those used in distributed generation and backup power systems, are a major health concern, and contribute to the formation of environmentally damaging acid rain and smog. Significant reductions in emissions of nitric oxide, particulate matter (PM), and other emissions would improve the environment and public health. In order to maintain and enhance environmental quality, there is a need for the development of clean generation equipment. At present, a device that is robust, efficient, durable, commercially-packaged, and maintenance-free is not available for controlling PM. Several devices using different filtration technologies with either thermal regeneration or manually replaceable filtration media were designed for this PM collection application. Unfortunately, these devices quickly clog and increase the exhaust back-pressure, negatively affecting engine efficiency and performance. Furthermore, thermal regeneration requires energy and produces high temperatures. Other technologies for PM control have costly energy requirements and/or lower efficiencies. A device that combines non-thermal plasma with electrostatic precipitation and diesel oxidation catalysis shows promise as an efficient, low-cost PM control device that does not have the performance deficiencies of other technologies. A prototype of this device was developed and tested under a previous NYSERDA contract with Rochester Institute of Technology.

Project Description

This was a two phase project. The overall objective was to develop a device that would improve air quality by reducing particulate emissions from DG diesel engine generators. Phase 1 of the project builds on the previous NYSERDA Contract 6867 to: (1) develop an optimized corona probe; (2) conduct further tests in-house at EET and at NYS DEC Automotive Emissions Laboratory to refine the prototype; and (3) develop a commercialization plan that would identify NYS manufacturers and stakeholders of this technology. The Objectives of Phase 2 of the project were to: (1) develop a robust multiple-probe NTP prototype for continuous use in full exhaust flow; (2) evaluate the performance of this device with tests at EET and AEL; (3) develop a commercial grade version of this NTP system for full exhaust treatment; and (4) begin commercialization process with NYS manufacturers and stake holders of this technology.


This could reduce particulate emissions from diesel generators that would lead to improved air quality. Emissions can be readily measured with and without the particulate trap installed on a diesel generator engine. Reduced particulate emissions will help to lower public health risks. It could result in a new product that can be manufactured in NYS and result in employment opportunities.

Project Results

Acceptable developmental progress was achieved for the device and a Final Report was prepared. Also, the Contractor progressed from a one-person startup company to a viable (but still incubation-level) small business with permanent staff for engineering, marketing, and administration, and part-time legal and additional support services.
