KleenAir to Exhibit Particulate and NOx Reduction Systems at the SAE Show in Detroit

    IRVINE, Calif.--Feb. 27, 2003--KleenAir Systems Inc. (OTCBB:KAIR) will be exhibiting at the Annual Convention of the Society of Automotive Engineers (SAE) in Detroit from March 3rd to 7th. Displayed at the Ford booth will be ServoTech's Ford licensed SOBRIS SCR and HC injection systems. Applications to be demonstrated include HC injection systems with a Dinex DPF Particulate Filter and a urea injection system with KleenAir's NOxMaster(R) SCR/DOC catalysts. Dinex, headquartered in Denmark, is the reseller of KleenAir's systems in Europe.
    The SAE has been a forum for reviewing and discussing a variety of alternative possible strategies for reducing NOx. In the past it has provided a platform leading to the adoption of particulate filter technology, such as that to be displayed. This year, SAE has implemented some striking changes that will benefit KleenAir Systems as this new format will expose them to a much wider marketplace.
    The Company's Chief Design Engineer for CarbonGuard (TM), Carroll Smith, who has been selected to receive a Triple "E" Lifetime Achievement Award from the SAE, will be in attendance at the KleenAir exhibit within the Ford stand.
    A number of automotive manufacturers are working on programs to integrate SCR systems by 2006, including testing of the ServoTech's Ford licensed SOBRIS SCR injection system. It is anticipated that both the EPA and the California Air Resource Board (CARB) will shortly introduce special test programs for SCR designed to launch approved SCR systems into the commercial marketplace.
    In Europe, where over 6 million diesel vehicles are manufactured annually, SCR technology has already been rigorously tested and approved by a variety of governmental authorities. KleenAir has recently been approved as the first SCR technology to be approved by the British Government for retrofit installations of SCR systems on vehicles in the UK, and is in discussion with other entities in a variety of other European countries.
    SCR technology significantly reduces nitrogen oxides and filter technology significantly reduces particulates. The SOBRIS system injects aqueous urea into the exhaust stream, which then converts to ammonia and interacts with NOx produced during combustion. The result converts environmentally hazardous NOx into harmless nitrogen and water. KleenAir's NOxMaster(R) SCR/DOC catalysts facilitate the interaction of ammonia and NOx. The combination offers a cost-effective bolt-on system suited to both retrofit applications in the field or integration into new vehicles. The system is suited for all sizes of vehicles from light-duty through heavy-duty.
