Navistar Collaborates With Clean Air Power To Develop MaxxForce Engine
Navistar has signed a concept development agreement with Clean Air Power (CAP) to develop MaxxForce 13 big bore engine to run on natural gas and clean diesel fuel, for the North American market.
Jack Allen, president of North American truck group at Navistar, said: “This agreement supports Navistar’s strategy of product leadership, offering our customers differentiated products merging the unique skills of Clean Air Power in natural gas combustion and the knowledge Navistar has in diesel combustion. The volatility of global diesel fuel prices and the significant natural gas reserves available in the US make natural gas an attractive option for customers focused on managing their fuel costs.”
According to Navistar, the program will utilize Clean Air Power’s dual-fuel combustion technology to deliver a MaxxForce 13 advanced EGR engine, which is fully compliant with US Environmental Protection Agency’s (EPA) 2010 on-highway diesel emissions, without use of liquid-urea SCR (selective catalytic reduction). The two companies will move forward to product development and validation, upon successful concept development.
MaxxForce 13 natural gas engines utilizing Clean Air Power’s dual-fuel combustion technology will initially target the regional haul tractor market with a goal of achieving a 400-mile range.
Eric Tech, president of engine group at Navistar, said: “As we assess changing market conditions, the ability to offer customers choice is important not only in our U.S. markets, but in our global markets as well. As we develop this product for our International brand truck customers, we will also be able to leverage the technology in other markets and products as appropriate.”
