                CLEAN DIESEL TECHNOLOGIES COMPLETES $9.5 MILLION
                                PRIVATE PLACEMENT

STAMFORD, CT (JANUARY 3, 2007)   Clean Diesel Technologies, Inc. (EBB:CDTI,
AIM:CDT/CDTS & XETRA:CDI), a developer of chemical and technological solutions
to reduce harmful engine emissions, announced today that it has secured
commitments totaling US$9.5 million in gross proceeds from new and existing
individual and institutional shareholders, as well as from directors and
management of the Company.  The private placement will result in Clean Diesel
issuing an aggregate of 7 million separable units of common stock and warrants
at a price of US $1.35 per unit.

     CEO Bernhard Steiner said the proceeds of the financing will provide
working capital, predominantly for the continued commercialization and
protection of its core technologies and products at a pivotal time for the
Company.

     Dr. Steiner added "In light of the growing concern for the effects of
global warming and air pollution, the world and its governments have adopted a
more focused attitude towards greenhouse gas emissions and especially the need
for the immediate reduction of particulate matter, oxides of nitrogen and fuel
consumption.  This acceleration and enforcement of legislation is requiring
polluters to reduce tailpipe and other emissions.  It is in precisely these
markets that our technologies have worldwide application, especially when they
enable cheaper and more effective use of existing pollution control systems."

     The units now being issued include shares of common stock, Class A Warrants
and Class B Warrants.  The Class A Warrants will entitle the holder until July
2, 2007 to purchase, at a price of $2.00 per share, one share of common stock
for every two shares acquired in the offering.  The Class B Warrants will
entitle the holder until December 29, 2007 to purchase, at a price of $2.50 per
share, one share of common stock for every two shares acquired in the offering.
The total number of shares of common stock which could be issued upon exercise
of all of the Class A and Class B Warrants is 7 million.  After completion of
this financing, Clean Diesel will have 33.2 million common shares outstanding
(approximately 44.9 million shares on a fully diluted basis).



     Directors and senior management have invested US$106,321 for a total of
78,756 common shares and 78,756 warrants.  These include Derek Gray,
non-executive Chairman of the Board of Directors, for 37,037 units; John de
Havilland, non-executive Director, for 25,000 units; Dr. Walter Copan, Executive
Vice President, North American Operations and Chief Technology Officer, for
7,410 units; Timothy Rogers, Executive Vice President, International Operations,
for 3,704 units; and Ann Ruple, Vice President Administration, Chief Financial
Officer and Treasurer, for 5,605 units.

     The placement of 7 million common shares and 7 million warrants was managed
and completed by the specialist environmental, London-based investment banking
house, Innovator Capital Limited.

     Application will be made for the common shares and the warrant shares, when
and if such shares are exercised, to be listed on AIM.  Trading of the new
common shares outside the US is expected to commence on or about January 8,
2007.

     The Company intends to file a registration statement with the US Securities
and Exchange Commission following completion of the audit of the Company's 2006
financial statements.
