avistar officials said the recent introduction of its 15-liter en- gine, its developments in alternative fuel engines, and growth in other areas have enabled the company to establish itself at a much broader level of industry leadership than five years ago. “With the addition of our Maxx- Force 15, our line-up of MaxxForce Advanced EGR big bore engines truly differentiates us from the com- petition,” said Jim Hebe, Navistar’s senior vice president, North Amer- ican sales operations. “The intro- duction of the ProStar+ with Maxx- Force 15 now gives customers the ultimate combination in durability and power.” Navistar is the only heavy-duty engine maker using exhaust gas re- circulation without selective cata- lytic reduction to meet federal emis- sions regulations. The MaxxForce 15 for the Inter- national ProStar+ is available with up to 500 hp and 1,850 lb.-ft. of torque. International PayStar heavy- duty vocational trucks are available with MaxxForce 15 up to 550 hp. Navistar also demonstrated a pro- totype 2011 International ProStar+ powered by a 13-liter MaxxForce dual fuel engine powered by diesel and liquefied natural gas. In partnership with Clean Air Power Ltd., Navistar has built and tested the 122-inch BBC tractor with a 430-hp, 1,550 lb.-ft. engine that uses diesel pilot injection for com- bustion on the compression stroke and mixes air and LNG on the in- take stroke. The result is an engine that runs on a mixture of 15 percent diesel and 85 percent natural gas. The dual fuel MaxxForce engine includes minimal changes to the stock diesel engine other than the addition of a natural gas injection system. Changes to the chassis in- clude the addition of a 26-inch di- ameter, 119-gallon standard LNG tank that provides a 400-mile range, a coolant heated fuel vaporizer, and an LNG regulator and filter.
