Dear Mr. Fairchild:
The California Air Resources Board (ARB) staff reviewed the emissions test data
submitted for a Detroit DieseI71-seriestwo$trok~die~elengine

compliance requirements fotarfexistiriglsngiheto
meet United States Environr11ental
Protection Agency (U ;S.EPA)tier2 marineenqineemlsstonstandards
or equivalent.
ARB is not certifying the engine rebuildkit, Rather, we areapprovinq engines-rebuilt
with this kit to comply with the Commercial, Harbor Craft Regulation U.S. EPA Tier 2
marine engine requirements. The rebuilt engine will have a new label attached
identifying the engine as rebuilt with this eCTS Detroit Diesel rebuild kit.
Two sets of emissions test data have been submitted for the GCTS Detroit Diesel
rebuild kit. These data sets are summarized in Table 1. Both sets of data showed ,
emissions rates below the U.S. EPATier 2 marine engine standards for the 71-series
Detroit Diesel engine. The U.S. EPA Tier 2 marine engine standards, which vary with
engine size, are summarized in Table 2 below. One set of emissions tests were
performed .by thebJhiversi~ of 'California.; ~jverside .(YCR.yano. theqth~rbySol.tthwest

"'The.emissions tests were conducted with.CARB diesel fuel:' The HarborCraft ','
Regulation allows compliance by demonstrating emissions levels that meet U.S. EPA
Tier 2 marine engine emission limits. The emissions test results for particulate matter
(PM), nitrogen oxides plus hydrocarbons (NOx+HC), and carbon monoxide (CO) are at
or below the U.S. EPA Tier 2 marine engine emission standards fora marine category 1
diesel engine with a per cylinder displacement of less than 1.2 liters/cylinder.

staff finds that the eeTS Detroit Diesel rebuild kit, when used with a Detroit Diesel
71-sedes engines, can be used to comply with the emission standard requirement in the
Commercial Harbor Craft Regulation for Tier 2 engines. This does not extend to the
Detroit Diesel 92-series engines because these engines are required to meet a stricter
Tier 2 PM emission standard.
A component parts list for this engine rebuild kit is attached to provide a means to
identify the individual parts specific to this rebuild kit. The component parts list may be

Dear Mr. Fairchild:
On behalf of the California Environmental Protection AgEmcy (CaUEPA). I am pleased to
forward an official certificate-for the Clean Cam Technology Systems' (CCTS) CamShaft Cylinder Reengineering Kit - Version I (for application-to Detroit-Diesel
Corporation's pre--1993-modelyearengines:
1~V-92, 12V-9_2,8V-92, 6V-92~ 16V-71,
12V-71, 8V-71 , 6V-71 , 6L-71 , 4L-71 , and-31-71). This performance certification is
- subject to the conditions in the Air Resources' Board (ARB) Executive Order ~G~96~29~
'038, which is also enclosed.
'
The control of exhaust emissions from stationery reciprocating -engines is an .important
part of GaUEPA's strategy to achieve and rnaintaln healthy air quality in California.
Upon review, local air 'management districts issue permits for stationary sources. The,
CCTS's Reengineering Kit can be incorporated in a districfs plan_to control nit~ogen
oxides, hydrocarbons, carbon monoxide, and particulate matter emissions.
I
-CCTS's custom earn Shaft and Cylinder Reengineering Xit allows the specified pre1993-model yea-r engines to meet 2001 exhaust emission standards established by U.S.
EPA and ARB. The Reengineering Kit modifies the camshattcyllnder
liner, and piston
along witl1 changing the fuel il1ljection timing and O>sYg~nratio to allow ~he engine to be
operated with lower emissions. ARB" staff at the CaUEPA has independently verified the operation ofthe iisted model year engines. Additional information about the Certificati.on of this technology is available at www.calepa.ca.gov/CaICertlcEutified.htn)

Increasing the use of innovative products that have a net environmental benefit will
assist CallEPA in improving our state's overall environmental quality. CallEPA has
endeavored to share certification information with our colleagues in environmental
protection, as well as potential technology customers. This year, we plan to eOncentrate
our efforts in advancing the acceptance of the California Environmental Technology
Certification Program (CaICert) among private and regulatory communities. I invite you.
to join the CalCert team ·in coordinating our outreach, marketing, and technical transfer
activities.
.
.
I have also enclosed a sorvey we developed to solicit client feedbaCk on the certification
process, cost, .and timeframe. We welcome your observations and opinions, particularly
any recommendations toward improving our service and your certification experience.
"Please complete the enclosed survey at your earliest convenience and return it to the
Office of Environmental Technology at P.O. Box 2815, Sacramento, CA 95812. Your
candid feedback will help CallEPA improve CalCert and ensure a more efficient and
responsive certification service.
Congratulations on the re-certification of the Reengineering Kit. We look forward to
continuing our cooperative association with Clean Cam Technology Systems to
facjlitate the development, use and transfer of innovative environmental sofutions.
Shouldyou have questions or need assistance in this endeavor, please contact.
Ms. Melissa Meuser, CalCert's marketing analyst, by telephone at (916) 445-6023 or
