exempted add—on or modified part continues to meet the standards and procedures of
California Code of Regulations, Title 13, Section 2474, et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION,
ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE
AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF ESW
TECHNOLOGIES‘ THERMACAT DIESEL PARTICULATE FILTER.

Violation of any of the above conditions shall be grounds for revocation of this Executive
Order. The Executive Order may be revoked only after a ten—day written notice of
intention to revoke the Executive Order, in which period the holder of the Executive
Order may request in writing a hearing to contest the proposed revocation. If a hearing
is requested, it shall be held within ten days of receipt of the request, and the Executive
Order may not be revoked until a determipation is made after a hearing that grounds for
revocation exist.

                                          EVALUATION SUMMARY

 Manufacturer Name: ESW Technologies

 Name of Device: ThermaCat diesel particulate filter

 Background:
        ESW Technologies (ESW) of 200 Progress Drive, Montgomerywlle Pennsylvama 18936
has requested exemption of its ThermaCat diesel particulate filter from the prohibitions in
Section 38391 of the California Vehicle Code. The ThermaCat diesel particulate filter is
designed for use on 1996 through 2010 model—year Tier 1 and Tier 2 off—road compression—
ignition engines with displacements from 3 to 17 liters.

Recommendation:
          Grant exemption to ESW as requested and issue Executive Order D—702U. The
  exemption covers ThermaCat diesel particulate filter installed on 1996 through 2010 model—year
  Tier 1 and Tier 2 off—road compression—ignition engines with displacements from 3 to 17 liters.
. The exemption covers engines used in mobile applications. It does not cover engines used in
  stationary applications such as pumps, compressors, or generators. This exemption is not valid
for any engines originally equipped with an aftertreatment emission control system such as a
catalytlc converter or a diesel particulate filter. Major components of the ThermaCat diesel
partlculate filter are identified in Attachment A.                   —

Device Description:                                      '
         The ThermaCat diesel particulate filter is an actively regenerated filtration system _
designed to reduce hydrocarbons, carbon monoxide, and particulate matter emissions from diesel
engines. It consists of a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), fuel
injfection system, backpressure sensor, temperature sensors, and an electronic control unit
(ECU). Particulate matter in the engine exhaust is captured on the ceramic wall—flow
filter. The filter is catalyzed to maximize passive regeneration. DOC, installed upstream of
the DPF, also promotes regeneration by increasing the exhaust temperature. When a pre—
determined condition is met (backpressure and exhaust temperature), fuel is injected in the
exhaust pipe between the exhaust manifold and the DOC. Fuel injection further increases
exhaust temperatures by promoting oxidation of hydrocarbons and raising the exhaust
temperature to the level required to support regeneration. The amount of injected fuel is
controlled by the ECU. The DOC—DPF module is installed with exhaust pressure and temperature
sensors. The system requires annual maintenance which includes cleanmg of the injector nozzle,
_DPF ash removal, and overall system check.

Discussion/Basis for the Recommendation:                                            |
       In support of its exemption request, ESW provided the following emission data:

Notes:
* Reported data are averages of three hot start tests.
** The device was degreened for 25 hours.
Test engine: 1996 Caterpillar 14.6 liter 3406 289 hp engme engine family TCP14. RZDBRJ
Test system: DOC ESW & DPF ESW
Test: 180 8178 C1 8—mode steady—state engine dynamometer test
Emission tests were conducted at ESW America, Inc. (ESWA; also known as Air Testing Services (ATS))
in Montgomeryville, Pennsylvania.

Data on the off—road engine showed no adverse emission impact from using the Thermacat
diesel particulate filter. To further support its exemption request, ESW provided field use
information. The Thermacat diesel particulate filter was installed on a Caterpillar dozer (engine
family 1CPXL10.5MRG; Tier 1) and operated for 1,020 hours. No problems or issues were
encountered during its operation.. Similar results are expected when the system is used on any
of engines include in this application.
