Detroit Diesel Corporation And Turbodyne Apply For EPA Certification

     DETROIT, MI., Aug. 13 /CNW-PRN/ - Detroit Diesel Corporation (DDC-NYSE)
announced today that Detroit Diesel and Turbodyne Technologies Inc.
(``Turbodyne'') (TRBDF-NASDAQ, TRBD-EASDAQ) submitted an application on July
16, 1997, to the United States Environmental Protection Agency for
certification under the Urban Bus Retrofit/Rebuild Program at the .1 gram
particulate emission level.  The application includes all mechanical unit
injection 6V92 engines manufactured between 1979 and 1989.
     Detroit Diesel and Turbodyne have responded to the challenge of providing
a cost effective means of complying to the EPA rebuild regulations, with
minimal impact on the fundamental engine and its performance.  The DDC/
Turbodyne kit includes parts traditionally replaced at time of overhaul, a
Turbopac(R) electric controlled supercharger and a catalytic converter.
Manufactured by Turbodyne, the Turbopac(R) supplies positive air intake
pressure at acceleration to optimize the fuel/air ratio.  The Turbopac(R)
mounts between the air inlet side of the turbo and the air cleaner.  Test data
for a rebuilt DDC 6V92 using the DDC/Turbodyne kit shows a reduction of
particulate emissions down to .09 grams per brake horse power hour.
     DDC and Turbodyne intend to offer the package in the form of complete
reliabilt(R) factory remanufactured engines, reliabilt(R) long blocks and
rebuild kits that the customer can install at time of overhaul.  The .10 gram
particulate rebuild kits can be purchased through authorized Detroit Diesel
distributors once certification is granted.

design, manufacture and marketing of high technology performance improvement
