Emissions measurements on natural gas buses in Tacoma, Washington, revealed high CO and NOx emissions. Replacement of the mixers on two buses produced dramatic reductions in CO and reduced NOx, while adjustment on the third bus reduced CO but did not appreciably affect NOx. Further research was conducted on LNG and diesel over-the-road tractors, and on CNG and diesel transit buses employing newer technology engines. Particulate matter (PM) was substantially lower for natural gas and NOx was reduced except in the case of the three transit buses that showed high NOx emissions. High variability of NOx emissions was also observed among the CNG fueled buses.
