Background

AFT’s Mission • Develop True “Clean Diesel Technology” • Help Improve World Energy Security • Aid in Reducing Global Warming

Methodology • Promote Development of a New Alternative Fuel-DME • Develop Fuel System Technology Needed for DME

CV of Jim McCandless • “65 –”66 Test Engineer, Detroit Aluminum & Brass • ‘68-69 Test Engineer, Continental Engines • ‘69-82 International Harvester-Division Chief EngineerDiesel Engines • ‘82-86 Director-Kohler Engine Div. • ‘86-93 VP-Engineering Navistar (International Truck & Engine Co.) • ’94-2005 Partner, AVL Powertrain Technologies • 2005…Managing Member, AFT • Many U.S. & International Patents on Diesel Engines

International Engines Developed by JMc & Associates

Powerstroke with “HEUI” Injector

DT 466 with HEUI Injector

Driving Force Behind HEUI Development: World’s First Common Rail

Advantages of DME • • • • •

No Soot Emissions (PM Trap Not Needed) Very Low NOx…Very High EGR Rates Low Injection Pressures (350-400 Bar) Low Cost, Abundant Fuel Multiple Feed Stocks…Natural Gas, Coal, Biomass • No Major Engine Changes Needed • Low Cost Fuel Injection System

Challenges & Status of DME • • • • •

No Significant Infrastructure for Distribution Low Liquid Viscosity (0.2 cSt) Very Poor Lubricity Technical Problems Solved China, Japan & Sweden Working on Infrastructure • Expect Commercial Use in China by 2010
