Anyone got a view on CDT please? They've had their technology approved by the US Environmental Protection Agency which took the price up to 260p a while back but then it fell back. First order just received from Coca Cola for trucks in three states in the US took price up 15-20p to 187p. Very tight market. Is the price up with events or ahead of expectations? Cheers.

CDT was building castles in the air from these previous updates...

CLEAN DIESEL TECHNOLOGIES ANNOUNCES NEW PURIFIER EMISSION CONTROL TECHNOLOGY TO MEET VEHICLE REQUIREMENTS OF EUROPEAN LOW EMISSION ZONES


London to Be First of 31 European Cities to Enforce Low Emission Zones;

Market Potential Estimated at More than 500 Million

Clean Diesel Technologies, Inc. ('Clean Diesel' or 'the Company')(EBB:CDTI, AIM:CDT/CDTS & XETRA:CDI), an innovation leader for clean energy and environmental technologies to reduce harmful engine emissions today announced that it has developed a range of retrofit emissions control technologies, called Purifier, to meet the requirements of the London Low Emissions Zone (LEZ). The Mayor of London recently approved plans for the implementation of a London-wide LEZ. In addition, Clean Diesel's Purifier technologies will benefit 31 other similar LEZs planned for metropolitan areas throughout Europe over the next three to four years. The goal of the LEZs is to dramatically reduce the number of heavily polluting commercial vehicles from entering large cities, including London starting in spring 2008, and to enable London and the other cities to achieve European Union air quality objectives.

Dr. Bernhard Steiner, Chief Executive of Clean Diesel Technologies, said Transport for London data indicate there are over 400,000 non-compliant vehicles entering London annually.. He stated that those and hundreds of thousands of vehicles throughout Europe would benefit from the Purifier technology. Dr. Steiner estimated the potential market opportunity for Clean Diesel's Purifier technologies in LEZs over the next few years in excess of 50 million.

Tim Rogers, Clean Diesel's Executive Vice President International, stated 'Purifier provides fleet operators a cost effective alternative to replacingtheir vehicles, which in itself offers a huge environmental impact. Furthermore, we are already well advanced with our European partners to license Purifier in many European countries. In London, we have already started the confirmatory test work required to obtain the low emissions certificate that proves LEZ compliance and expect to finish that additional testing by August 2007. We consider the LEZ movement to be a significant opportunity for us and have been developing technology for vehicle emission control for many years, in anticipation that this market would flourish.'

Commercial operators wishing to enter the London LEZ, as confirmed recently by Mayor Ken Livingstone, can either opt to pay a fixed fee of 200 per day or ensure that their vehicles comply with Euro III standards on particulate matter. Almost two-thirds of particulate matter and half of the emissions of oxides of nitrogen (two of the key pollutants of concern in London) are from road transport. The LEZ applies specifically to diesel engine trucks, buses, coaches, large vans and minibuses.

Mr. Rogers said, 'The Clean Diesel Purifier technology systems are among the lowest priced solutions on the market and are designed to ensure all vehicles are made compliant within the LEZ. Existing retrofit particulate filter systems on the market are often unnecessarily complex and require a comparatively high level of maintenance.'

Clean Diesel has a range of Purifier technology products including the Purifier E4, to upgrade vehicles from Euro I to Euro III emissions levels, or from Euro II to Euro IV standards and the Purifier E3 to upgrade from Euro II to Euro III standards. These products are based on Clean Diesel's Purifier particulate matter filtration technology which has been verified in the Environmental Technology Verification of the U.S. Environmental Protection Agency, and its diesel particulate filter technology which has been approved by the European VERT.

The Purifier products have been extensively tested and are in commercial use around the world. As well as reducing particulate matter, the Company's Purifier products are also neutral with regards to harmful nitrogen dioxide(NO2) emissions, which are often an unwanted by-product of many of the catalyzed emission systems currently in use.

Clean Diesel Technologies is currently offering to license its Purifier
technologies to systems integrators and to other suppliers of emission control solutions. The Company's products were well received during April's Commercial Vehicle Show in Birmingham, England by many including haulers and bus companies.

CLEAN DIESEL AND ROBERT BOSCH GmbH ENTER AGREEMENT ON SELECTIVE CATALYTIC REDUCTION (SCR) TECHNOLOGY

Targets Global Vehicle Markets

Stamford, CT... Clean Diesel Technologies, Inc. ('Clean Diesel Technologies' or
'the Company') (EBB:CDTI, AIM:CDT/CDTS & XETRA:CDI), an innovation leader for
clean energy and environmental technologies to reduce harmful engine emissions,
said today that it has signed a binding contract for a worldwide non-exclusive
licensing agreement with Stuttgart, Germany-based Robert Bosch GmbH, a leading
global supplier in the areas of automotive and industrial technology, customer
goods and building technology.

Under the agreement, Robert Bosch GmbH has secured non-exclusive worldwide
rights to patents held by Clean Diesel Technologies for control of oxides of
nitrogen (NOx) emission by selective catalytic reduction (SCR). The patents
Bosch has agreed to license include Clean Diesel's ARIS(R) method of
single-fluid return-flow cooled urea injection for SCR control of NOx emissions,
as well as patents covering the combination of exhaust gas recirculation (EGR)
with SCR to minimize toxic emissions while optimizing vehicle fuel efficiency.
SCR has been recognized as a leading technology for controlling NOx emissions,
as required to meet international environmental standards now being implemented.
In addition to providing a cost-effective control of NOx emissions, these
inventions of Clean Diesel Technologies provide improved fuel economy, also
contributing to reduced vehicle carbon dioxide and other greenhouse gas
emissions. The agreement also includes provision for the use of these
technologies in non-vehicular applications such as stationary power generation,
rail and marine.


The terms were not disclosed, but Clean Diesel said that its licensing
agreements generally are structured around license initiation fees and running
royalty payments. Clean Diesel expects its 2007 financial results to include
the first revenue under this agreement. Products incorporating these emission
control and fuel-efficiency SCR technologies have been developed by Bosch and
are likely to further gain in market acceptance.
With many years of research and development, accompanied by rigorous testing and work with regulatory bodies internationally, Clean Diesel Technologies' robust
portfolio of intellectual property is poised to lead the growing green, clean-air movement around the world with its solutions to clean up major pollutants such as oxides of nitrogen, targeted by this agreement.

Clean Diesel Technologies CEO Bernhard Steiner commented, 'Through this new
relationship with Bosch, an industry leader whose products are included in all
classes of engines and vehicles manufactured around the world, we are happy to
announce this agreement as a further endorsement of the value of the Clean Diesel Technologies emission control inventions. This is a significant step for our Company. Clean Diesel has had prior agreements with major companies addressing retrofit markets, and this is the first license targeting a substantial portion of the new diesel vehicles with SCR technology that are predicted to be built over the next several years. These SCR patents were originated and developed to address the global need for cleaner air through emissions control, sustainability and fuel efficiency.'

Clean Diesel Technologies Executive VP and Chief Technology Officer Walter Copan
added, 'The increasing concern over the impacts of air pollution has resulted in
substantially more demanding requirements to control oxides of nitrogen,
particulate matter and carbon dioxide emissions, while also reducing fossil fuel
consumption. Our patented platform technologies have worldwide application
directly addressing these areas. Bosch has the expertise and full range of
capabilities to deliver these integrated SCR emission control solutions to
original equipment manufacturers and its other customers around the world.'

Stamford, CT, Clean Diesel Technologies, Inc. ('Clean Diesel Technologies' or 'the Company') (EBB: CDTI, AIM: CDT/CDTS & XETRA: CDI), an innovation leader for clean energy and environmental technologies to reduce harmful engine emissions, reported results for its first quarter ended March 31, 2007. Total revenue for
the quarter was US$216,000 with a net loss of US$1.8 million, or US$0.06 loss per share, versus revenue of US$269,000 for the comparable quarter of 2006 with a net loss of US$1.6 million, or US$0.06 loss per share. The higher revenue last year was due primarily to a market assessment consulting project that generated US$73,000 in the 2006 quarter.

During the first quarter of 2007, the Company made substantial progress in its ongoing initiative to achieve technology license agreements with significant manufacturers and component suppliers. Clean Diesel Technologies will announce its achievements as agreements are signed and its licensees have consented to the contents of the announcements.

'We are confident this will be a landmark year for Clean Diesel,' said Dr.Bernhard Steiner, President and CEO. 'The quarter's numbers don't tell the interesting part of the story, but it is worth emphasizing that with our cash on hand and the potential for additional financing from the exercise of our outstanding warrants, we will have enough staying power to achieve our strategic goals. As of today, we are poised for growth through OEM and Tier-One supply and licensing agreements, some of which have been in test and negotiation for many years. The progress we have made in our license negotiations is leading to exciting new opportunities for the Company and its partners.'

Dr. Walter Copan, Executive VP and Chief Technology Officer, said, 'The growing concern over the effects of air pollution has resulted in substantially more demanding requirements to control oxides of nitrogen, particulate matter and carbon dioxide emissions, while also reducing fossil fuel consumption. Our patented platform technologies have worldwide application in precisely these areas.'

Dr. Steiner added that the strength of the worldwide movement toward more environmentally friendly technology promises to benefit Clean Diesel in the coming months because of the Company's focus on expanding application of technologies and solutions designed to improve fuel efficiency and reduce harmful engine emissions.

'Over the course of the Company's existence, we have performed extensive and rigorous testing at best-in-class reference sites, collecting significant data that have enabled us to gain the respect of regulators and the interest of major manufacturers worldwide. We are proud that our technologies can clean up vehicles already on the road as well as those from the OEM market, along with stationary engines for such applications as power generation - but perhaps more importantly, we believe our technologies can provide keys to producing ultra-low emission vehicles in the future. The upside is that our technologies also provide significant fuel savings so that implementation 'pays for itself','Steiner said.

Additive revenue in the three months ended March 31, 2007 was US$122,000 compared to US$150,000 in the prior year quarter, a decrease of US$28,000, or 18.7%, due to a shift in order placement resulting from a transition of supply chain to distribution partners. Hardware revenue was US$83,000 in the 2007 first quarter compared to US$45,000 in the same 2006 period, an increase of US$38,000, or 84.4%, due to increased sales of our ARIS advanced reagent injector and dosing systems for selective catalytic reduction. License fees and royalty revenue was US$11,000 in the three months ended March 31, 2007 compared to US$1,000 in the three months ended March 31, 2006, an increase of US$10,000 primarily due to royalty payments related to the Company's ARIS technology.

Operating costs and expenses were US$2,058,000 in the three month ended March 31, 2007 compared to US$1,906,000 in the comparable 2006 period, an increase of US$152,000, or 8.0%, reflecting higher selling, general and administrative expenses and higher patent-related costs, partially offset by lower research and development expenses. Selling, general and administrative expenses included US$551,000 of non-cash charges for the fair value of stock options compared to US$53,000 in non-cash share-based compensation expense in the three months ended March 31, 2006 in accordance with SFAS No. 123R, which the Company adopted in January 2006. The 2006 period also included US$357,475 of severance charges for the former president and chief operating officer who had been released from employment in January 2006. Research and development expenses were US$176,000 lower than the same prior year period because the 2006 period included significant special costs on a project that was then substantially completed. Patent-related costs were higher in the 2007 period due to additional costs associated with the protection of the CDT patents.

Clean Diesel's CFO Ann Ruple noted that at March 31, 2007, the Company had cash and cash equivalents of US$6,298,000 and working capital of US$6,725,000. In the three months ended March 31, 2007, the Company's operating activities used US$2,050,000 of cash (primarily to fund the 2007 net loss) and its investing activities used US$40,000(predominantly for investments in the Company's patents). Cash provided by financing activities was US$3,074,000 in the three months ended March 31, 2007, due primarily to proceeds from collection of subscriptions receivable from the 2006 private placement.
