Micro Bird Brings CARB-Certified Propane Bus to Market

Micro Bird says it is the first company to bring a Type A propane autogas school bus with low nitrogen oxides to market.

The company’s G5 Type A bus equipped with ROUSH CleanTech’s Gen 5 propane fuel system is certified to California Air Resources Board’s optional low nitrogen oxide emissions standard of 0.05 grams per brake horsepower-hour (g/bhp-hr), making it 75% cleaner than federal U.S. emission standards. Type A buses, made of a bus body constructed on a cutaway front-section vehicle, usually carry nine to 36 students.
