In what it is describing as the first commercially-available compressed natural gas (CNG) concrete mixer, McNeilus Truck and Manufacturing will offer a choice of Bridgemaster and standard versions on either a Kenworth W900 or T800 chassis. Meeting EPA 2010 heavy-duty engine emission standards for nitrogen oxides and particulate matter, the CNG-powered concrete mixers will be fitted with a six-cylinder, 8.9-liter Cummins ISL G engines developed by Cummins Westport of Canada. CNG platforms for other manufacturer's chassis are pending, says McNeilus.
