                          NOTES TO FINANCIAL STATEMENTS
                               September 30, 2002
                                   (Unaudited)

BASIS  OF  PRESENTATION

     The  accompanying  unaudited,  consolidated  financial statements have been
prepared  in  accordance  with  accounting  principles generally accepted in the
United  States  for  interim  financial information and with the instructions to
Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all
of  the  information  and  footnotes required by accounting principles generally
accepted  in the United States for complete financial statements. In the opinion
of management, all adjustments considered necessary for a fair presentation have
been  included. All such adjustments are of a normal recurring nature. Operating
results  for the nine-month period ended September 30, 2002, are not necessarily
indicative  of the results that may be expected for the year ending December 31,
2002.  For  further information, refer to the Financial Statements and footnotes
thereto  included  in  the  Company's  Form 10-K for the year ended December 31,
2001.

     Clean  Diesel  Technologies, Inc. (the "Company" or "CDT") was incorporated
in  the  State  of Delaware on January 19, 1994, as a wholly owned subsidiary of
Fuel-Tech  N.V. ("Fuel Tech").  Effective December 12, 1995, Fuel Tech completed
a  Rights Offering of the Company's Common Stock that   reduced its ownership in
the  Company to 27.6%. Fuel Tech currently holds a 16.3% interest in the Company
as  of  September  30,  2002.

     The Company is a specialty chemical and energy technology company supplying
fuel  additives  and  proprietary  systems  that  reduce  harmful emissions from
internal  combustion  engines  while improving fuel economy.  Prior to 2000, the
Company was a development stage enterprise devoted to research, development, and
commercialization  of  platinum  fuel  catalysts (PFCs) and Nitrogen Oxide (NOx)
reduction  technologies  for  diesel engines.  During December 1999, the Company
received its EPA registration for its platinum - cerium product and recorded its
first  commercial  sales.  Accordingly, in the opinion of management the Company
was  no  longer  a  development  stage enterprise.  The success of the Company's
technologies  will  depend  upon  the  commercialization  opportunities  of  the
technologies  and  governmental regulations, and corresponding foreign and state
agencies.

     Prior  to  2000,  the  Company  was  primarily  engaged  in  research  and
development  and  has  incurred  losses  since  inception  totaling  $21,625,000
(excluding  non-cash  preferred  stock dividends).  In management's opinion, the
Company's  cash  balance  at September 30, 2002 and the $1.4 million raised from
investors  in October 2002 (see Subsequent Events section) will be sufficient to
fund  the  Company's  operations  into the fourth quarter 2003.  The Company may
require  additional  capital  to  fund its future operations and working capital
needs.  Although  the  Company  believes  that it would be successful in raising
additional  capital,  there  is  no guarantee that it will be able to raise such
funds  on  terms  that  will  be  satisfactory to the Company.  The Company will
develop  contingency  plans  in  the  event  future  financing  efforts  are not
successful.  Such  plans  may include reducing expenses and selling or licensing
some  of  the  Company's  technologies.

INVENTORIES

     Inventories  are  stated  at  the  lower  of  cost or market and consist of
finished  product.  Cost  is  determined  using  the  first-in, first-out (FIFO)
method.

INTANGIBLE  ASSETS

     In  fiscal  year 2002, the Company began capitalizing the costs of patents.
Patents  include costs to secure patents on technology developed by the Company.
Patents  are  amortized on a straight-line basis over the remaining useful lives
of  three  to  eighteen  years.  Patents  are evaluated for potential impairment
whenever  events  or circumstances indicate that undiscounted cash flows are not
sufficient  to  recover  their  carrying  amounts.

REVENUE  RECOGNITION

     The  Company  recognizes  revenue  from  sales  of Platinum Plus fuel borne
catalyst  and  ARIS  2000  systems  upon  shipment.

     In  April  2001,  the Company amended its February 2000 ARIS Stationary NOx
Reduction  license  agreement with the RJM Corporation.  Under the amended terms
of the license agreement, the Company received two fixed non-refundable payments
of  $412,500  each  on  June  1 and September 1 in lieu of potentially receiving
$1,040,000  on  the  second  or  third  anniversary.  The Company recognized the
$825,000 as license revenue in 2001.  The Company receives unit royalties on all
ARIS  sales  of  stationary,  marine  or  locomotive  applications  by  RJM.

     In August 2001, the Company completed a license agreement with Mitsui & Co.
Ltd  for  CDT's  ARIS  2000  NOx  control system for all stationary diesel power
generators  in Japan. Under the agreement, the Company received a non-refundable
upfront license payment of $495,000, and will receive ongoing standard royalties
on  each  system  sold  by Mitsui. The Company recognized the license payment as
revenue  in  2001, as there were no significant ongoing services to be performed
by  the  Company.  Mitsui  also has an option to license the ARIS technology for
mobile  applications  in  Japan  for  an  additional  license  fee.

     Royalty fees are recognized by the Company when earned.

STOCKHOLDERS'  EQUITY

     During  December 2001, the Company received proceeds of $3.721 million (net
of  $0.644  million  in  expenses  and  $0.817  million in term loan re-payment)
through  private  placements  of  2,580,664  of  its Common Stock.  In 2000, the
Company  received  $1.021  million through private placements of 1,362 shares of
its  Series  A  Preferred  Stock.  In addition, in 1999 $1.75 million was raised
through  a  private  placement  of  3,500 Series A preferred stock shares and in
1998, $1.4 million of bridge loans and $0.5 million of term loans were converted
into  2,800  and  1,029  shares  of  Series  A  Preferred  Stock.

     During  2001,  $1,897,000 of non-cash stock dividend and conversion premium
were  declared for the Series A preferred stock and converted into the Company's
Common Stock. On December 28, 2001, the Company converted all outstanding Series
A Preferred Stock (15,897 shares) including accrued stock dividends, into Common
Stock  (5,934,829  shares).

EARNINGS  PER  SHARE

     Employee stock options and stock purchase warrants were not included in the
computation  of  diluted earnings per share for 2002, because either the Company
reported  a  loss  for the period or their exercise prices were greater than the
average  market  price  of the common stock and therefore would be antidilutive.



RELATED  PARTY  TRANSACTIONS

     In  November 2000, the Company secured a $1,000,000 term loan facility at a
10%  interest rate from several preferred shareholders, including Fuel Tech Inc.
which  pledged  $250,000.   In  2000  and  2001 the Company drew down the entire
$1,000,000  term  loan.  In  December  2001,  $750,000  of term loan and accrued
interest  was  repaid  as  part of the December 2001 private placement of common
stock  discussed in the stock holders equity note.  In January 2002, the Company
repaid  the  remaining $250,000 term loan payable to Fuel Tech Inc. plus accrued
interest.

     The  Company  has a Management and Services Agreement with Fuel Tech. Under
the  agreement,  the Company pays Fuel Tech a fee equal to an additional 3 - 10%
of  the  costs  paid  on  the Company's behalf, dependent upon the nature of the
costs  incurred.  Currently,  a fee of 3% is assessed on all costs billed to the
Company from Fuel Tech.  Charges to the Company, inclusive of the administrative
fee,  were  approximately  $17,300  in  both the third quarter of 2002 and 2001.

COMMITMENTS

     Effective  October  28, 1994, Fuel Tech granted two licenses to the Company
for  all  patents  and  rights  associated  with  its  platinum  fuel  catalyst
technology.   Effective  November  24, 1997, the licenses were canceled and Fuel
Tech  assigned to the Company all such patents and rights on terms substantially
similar  to  the  licenses. In exchange for the assignment, the Company will pay
Fuel  Tech  a  royalty  of  2.5%  of  its annual gross revenue from sales of the
platinum  fuel  catalysts  commencing in 1998. The royalty obligation expires in
2008.  The  Company may terminate the royalty obligation to Fuel Tech by payment
of  $7,636,364 in 2002 and declining annually to $1,090,910 in 2008. The Company
as  assignee and owner will maintain the technology at its own expense. The 2001
royalties of $2,673 were paid to Fuel Tech in 2002 and royalties payable to Fuel
Tech  at  September  30,  2002  were  $683.

MARKETING  AND  LICENSE  AGREEMENTS

     In  March 2001, the Company licensed the Lubrizol Corporation to distribute
and blend the Company's patented Platinum Plus fuel borne catalyst in Europe for
use  with  particulate  filters.  The  seven  year  exclusive agreement includes
minimum annual sales performance requirements.  Effective November 1, 2002, as a
result  of changing market conditions in the European particulate filter market,
the  Company  and Lubrizol mutually agreed to terminate their Platinum Plus fuel
borne  catalyst  agreement.

     In  June  2001  the  Company announced a non-exclusive distribution license
agreement  with  Baker  Petrolite,  a division of Baker Hughes.  Baker Petrolite
will  distribute CDT's patented Platinum Plus diesel fuel combustion catalyst to
refineries  and  fuel  terminals  in  the  U.S.  and  Canada.

     In August 2001, the Company completed a license agreement with Mitsui & Co.
Ltd  for  CDT's  ARIS  2000  NOx  control system for all stationary diesel power
generators  in  Japan.  Under the agreement, the Company received non-refundable
upfront license payments of $495,000 and will receive ongoing standard royalties
on  each  system  sold by Mitsui.  Mitsui also has an option to license the ARIS
technology  for  mobile  applications  in  Japan  for an additional license fee.

     In  September  2001,  the  Company  signed  a license agreement with Global
Companies  LLC  for  bulk  treatment  of diesel fuel with the Platinum Plus fuel
additive.  Global  Companies  LLC  of Waltham, MA will be the exclusive terminal
blender  of the Platinum Plus diesel fuel combustion catalyst in New England for
delivery  to  select  fuel  marketers  and  fleet  customers.

SUBSEQUENT  EVENTS

     In  October  2002, the company raised $1.4 million in common stock at $2.00
per  share  from several existing institutional shareholders. The new shares are
being  issued  in  reliance  with Regulation S under the U.S. Securities Act and
because they are subject to transfer restrictions for a period of time, they may
not  be  resold  to  persons  in  the U.S. or U.S. persons, but may otherwise be
traded  in  the  UK without other restrictions. The shares will be traded on AIM
under  the  ticker/symbol  CDTI.

     Effective  November  1,  2002, as a result of changing market conditions in
the European particulate filter market, the Company and Lubrizol mutually agreed
to  terminate  their  Platinum  Plus  fuel  borne  catalyst  agreement.

Item 2.   Management's  Discussion  and  Analysis  of  Financial  Condition
          and  Results  of  Operations


FORWARD-LOOKING  STATEMENTS

     Statements  in  this  Form  10-Q  that  are not historical facts, so-called
"forward-looking statements," are made pursuant to the safe harbor provisions of
the  Private  Securities Litigation Reform Act of 1995.  Investors are cautioned
that  all  forward-looking statements involve risks and uncertainties, including
those  detailed  in  the  Company's  filings  with  the  Securities and Exchange
Commission.  See  "Risk Factors of the Business" in Item 1, "Business," and also
Item 7, "Management's Discussion and Analysis of Financial Condition and Results
of  Operations" in the Company's Form 10-K for the year ended December 31, 2001.


RESULTS  OF  OPERATIONS

     Prior  to  2000,  the  Company  was  a development stage enterprise and its
efforts  were  devoted  to  the  research,  development and commercialization of
platinum  fuel  catalysts  and  nitrogen  oxide reduction technologies to reduce
emissions  from  diesel engines.  During December 1999, the Company received its
US  EPA registration for its platinum-cerium fuel catalyst product and completed
its  first  commercial  sales.

     Product  sales  and cost of sales were $39,000 and $17,000 respectively for
the  third  quarter  of 2002 versus $65,000 and $50,000 for 2001.  Platinum Plus
fuel catalyst sales of $11,000 and $16,000 were recorded in the third quarter of
2002  and  2001,  respectively.  ARIS product sales of $28,000, primarily due to
Mitsui  &  Co.,  Ltd.,  were  recorded  in  the  third  quarter  of  2002.

     Included  in  the  2002  and  2001  third  quarter  revenue  is $12,000 and
$434,000,  respectively,  of  license  and royalty income.  The 2002 license and
royalty  income  is  from  a  major European diesel fuel system supplier for a 6
month  lease  of  an ARIS 2000 system.  In 2001, CDT received a one-time license
payment  from  Mitsui  & Co., Ltd.  CDT earns a royalty on all sales of the ARIS
2000  system.

     Year-to-date  sales  and  cost  of  sales were $141,000 and $72,000 in 2002
versus  $1,443,000        and  $109,000  in  2001.  Included  in  the total year
revenue  is  $26,000 and $1,290,000 of ARIS license and royalty revenue for 2002
and  2001  respectively.  Year-to-date  Platinum  Plus  FBC  sales for 2002 were
$28,000  versus  $101,000  in  2001.

     General  and  administrative expenses increased $108,000 to $569,000 in the
third  quarter  2002  versus $461,000 in the same period of 2001.  For the first
nine  months  of  2002 general and administrative expenses increased $358,000 to
$1,704,000  versus  $1,346,000  in 2001.  The rise in spending is related to the
hiring  of  a  Vice President of Sales and Marketing in April 2002, increases in
salaries  and  marketing  related costs associated with the commercialization of
the Platinum Plus-FBC.  The 2002 year-to-date general and administrative expense
also  includes  a  one-time  $95,000  non-cash  charge  for  additional  2001
compensatory  stock  warrant  expense  to  a  third  party.

     Research  and  development  expenses  increased $107,000 to $185,000 in the
third quarter 2002 versus $78,000 in the comparable period in 2001. For the year
research  and  development  costs are up $343,000 to $597,000 versus $254,000 in
the  same  period  in 2001. The increase is attributable to the start of several
verification  and  certification  programs  for  the  Platinum  Plus  FBC.

     Patent  filing  costs  decreased  $34,000 to $4,000 in the third quarter of
2002 versus $38,000 in the comparable 2001 period.  During the second quarter of
2002,  the  Company  began  capitalizing its patent costs and will amortize such
costs  over  the  life  of  the  related  patent.  For  the year patent cost has
decreased $107,000 to $31,000 versus a $138,000 in the same nine month period in
2001.

     Third  quarter  interest  income  increased $4,000 in 2002 to $7,000 versus
$3,000 in the comparable period in 2001.  For the year interest income increased
$23,000  to  $32,000 versus $9,000 in the same period in 2001. This was a result
of  an increase in the amount of cash and cash equivalents on hand in 2002.  For
the  year  interest  expense  declined  to $9,000 from $64,000 in the first nine
months  of 2001 as the result of the repayment of the term loan in January 2002.


                                      -9-

LIQUIDITY  AND  SOURCES  OF  CAPITAL

     Prior  to  2000,  the  Company  was  primarily  engaged  in  research  and
development  and  has  incurred  losses since inception aggregating $ 21,625,000
(excluding the effect of the preferred stock dividends).  The Company expects to
incur  losses  through  the  foreseeable  future  as  it  further  pursues  its
commercialization  efforts.  Although  the  Company  started  selling  limited
quantities  of  product in 1999 and licensing revenue in 2000, sales and revenue
to  date  have  been  insufficient  to cover operating expenses, and the Company
continues  to  be  dependent  upon  sources other than operations to finance its
working  capital  requirements.

     For  the  nine  months  ended September 30, 2002 and 2001, the Company used
cash  of  $2,176,000  and  $602,000  respectively,  in  operating  activities.

     At  September 30, 2002 and December 31, 2001, the Company had cash and cash
equivalents  of  $1,462,000  and $4,023,000, respectively.  The decrease in cash
and  cash  equivalents  in  2002  was  the  result of payments made for expenses
related  to  the  stock offering in December 2001, various product certification
programs  and  the  normal  on-going  operations  of  the  Company.  The Company
anticipates  incurring  additional  losses  through  at least 2002 as it further
pursues  its  commercialization  efforts.

     The  Company  signed  an  agreement with the RJM Corporation on February 2,
2000  which  licensed  RJM  to  sell  CDT's ARIS 2000 NOx control system for all
stationary,  marine,  and  locomotive  applications in North, Central, and South
America.  Under  terms of the agreement CDT received an initial $360,000 license
fee  and  inventory  payment.

     In  April  2001,  the Company amended its February 2000 ARIS Stationary NOx
Reduction  license  agreement with the RJM Corporation.  Under the amended terms
of the license agreement, the Company received two fixed non-refundable payments
of  $412,500  each  on  June  1 and September 1 in lieu of potentially receiving
$1,040,000  on  the  second or third anniversary of the license agreement.   The
Company  will  continue to receive unit royalties on future sales of stationary,
marine  or  locomotive  applications  by  RJM.

     In  August  2001, the Company completed a license agreement with Mitsui for
CDT's ARIS 2000 NOx control system for all stationary diesel power generators in
Japan.  Under the agreement, the Company received non-refundable upfront license
payments  of $495,000 and will receive ongoing standard royalties on each system
sold  by  Mitsui.  Mitsui  also has an option to license the ARIS technology for
mobile  applications  in  Japan  for  an  additional  license  fee.

     In  November 2000, the Company secured a $1,000,000 privately financed term
loan  facility.  In  December  2000,  the Company drew down $500,000 of the term
loan  facility  and  in  March  2001 the remaining $500,000 of the term loan was
drawn  down.  As  part  of  the  private placement stock transaction in December
2001,  $750,000 of the outstanding term loan plus accrued interest was converted
to  common stock.  The remaining $250,000 plus accrued interest was paid in cash
in  January  2002.

     In  December 2001, the Company received $3.721 million (net of expenses and
term  loan  repayment)  through  a  private placement of 2,580,664 shares of its
common  stock.  In conjunction with the private placement, the Company converted
all  of  its  Series  A  Preferred  Stock to Common Stock.  All of the Company's
Common  Stock  shares  were  registered  to trade on the AIM of the London Stock
Exchange.

     As  a  result  of the Company's recurring operating losses, the Company has
been  unable  to  generate  a  positive cash flow.  In management's opinion, the
Company's  cash  balance  at  September  30, 2002 and the $1.4 million raised in
October  2002  private  placement  (see  Subsequent  Events  section)  will  be
sufficient  to  fund the Company's operations into the fourth quarter 2003.  The
Company  may require additional capital to fund its future operations.  Although
the  Company believes that it will be successful in its capital-raising efforts,
there  is  no  guarantee  that it will be able to raise such funds on terms that
will be satisfactory to the Company.  The Company will develop contingency plans
in  the  event  future  financing  efforts  are  not successful.  Such plans may
include  reducing  expenses  and  selling  or  licensing  some  of the Company's
technologies.

ITEM 3.   QUANTITATIVE  AND  QUALITATIVE  DISCLOSURES  ABOUT  MARKET RISK

     In  the  opinion  of  management,  with  the  exception  of  exposure  to
fluctuations  in  the  cost  of  platinum,  the  Company  is  not subject to any
significant  market  risk  exposure.

     The  Company  generally  receives all income in United States dollars.  The
Company  typically  makes  several  small  payments  monthly  in various foreign
currencies  for patent expenses, product tests and registration, local marketing
and  promotion  and  consultants.


ITEM 4.   CONTROLS  AND  PROCEDURES

     Within  90  days  prior  to  the filling date of this report, the Company's
certifying  officers  performed  an  evaluation  of  the  effectiveness  of  the
Company's  disclosure  controls  and  procedures.  The  disclosure  controls and
procedures  were determined to be sufficient to ensure that material information
relating  to the Company, including its consolidated subsidiaries, is made known
to the certifying officers within those entities, particularly during the period
in  which  this  quarterly  report  is  being  prepared.

     There  were no significant changes in the registrant's internal controls or
in  other  factors  that could significantly affect these controls subsequent to
the  date  of  their evaluation, including any corrective actions with regard to
significant  deficiencies  and  material  weaknesses.
