Save The World Air's CAT-MATE Anti-Pollution Device Successfully Completes Motorcycle Tests at Independent VCA-Certified Laboratory LOS ANGELES, Sept. 8 /PRNewswire-FirstCall/ -- Final tests conducted at an independent Hong Kong laboratory approved by Britain's Vehicle Certification Agency (VCA) found that the CAT-MATE pollution-reduction device developed by Save The World Air, Inc., (OTC:ZERO) cut carbon monoxide emissions from a two-stroke motorcycle engine by an average 78%, the company announced today. "These test results are the validation we have been waiting for," said Edward Masry, SWA's Chief Executive Officer. "They demonstrate the CAT-MATE's real ability to reduce emissions and are a key step in our efforts to bring this product to market." The tests were conducted at the Hong Kong Exhaust Emission Laboratory (HKEEL), which has been certified by the VCA of the United Kingdom to conduct tests based on European Community (EC) and United Nations Economic Commission for Europe (ECE) standards. SWA now plans to submit its findings to the VCA's Asian headquarters in Nagoya, Japan. The VCA, an executive agency of the UK Department for Transport, is responsible for the certification of vehicles from many of the world's leading manufacturers. Multiple tests conducted under closely controlled conditions on a 150cc two-stroke Honda motorcycle engine showed that SWA's CAT-MATE device reduced carbon monoxide (CO) emissions by an average 78%, nitrous oxide (NOX) emissions by 75%, and total hydrocarbon (THC) emissions by more than 50%. Similar tests of the CAT-MATE device conducted at HKEEL in July on a 63cc two-stroke generator engine showed a similar reduction in toxic emissions. The CAT-MATE works in conjunction with the catalytic converter to drastically reduce emissions by 2- and 4-stroke engines, which are a major source of air-borne pollution around the world. According to the U.S. Environmental Protection Agency, two-stroke engines account for almost 1.1 billion pounds of hydrocarbon emissions each year, contributing to an estimated 38 million respiratory ailments a year throughout the world. The problem is most acute in Asia, where two-stroke motorcycles are a leading form of transportation. "Emissions by these engines are taking a daily toll on the health of people in Asia. We are very excited that the CAT-MATE has demonstrated its potential to literally save lives that might otherwise be lost to pollution-induced ailments," said Erin Brockovich, SWA's Vice-President for Environmental Affairs. In order to evaluate market conditions and opportunities in Asia, senior Save the World Air executives will embark on a tour of Asian markets such as Thailand and Indonesia in the coming weeks. The SWA executives plan to meet with government officials, business leaders, environmentalists and automobile manufacturers. Save The World Air said that it is maintaining its previously-announced target of commencing production of the CAT-MATE in early 2005. Save The World Air, Inc., was created to develop devices using proprietary technologies that can be installed on motor vehicles to reduce harmful emissions, improve fuel efficiency, and/or improve performance.
