The results demonstrate that when properly installed, the HYFS Fuel 2(TM) technology allows a diesel engine to exceed federal and state emission reduction standards. HYFS recently announced that company's "No School Bus Left Behind Initiative(TM)," a total emission control/monitoring program under which HYFS proposes to convert school buses with the Company's Fuel 2(TM) non-invasive patent conversion technology and followed with quarterly emission audits to ensure the highest level of pollution reductions are maintained.
