HOW CAN WE HELP YOU?

Building on the more than 24 years of the industry's longest running diesel research consortium, the Clean High-Efficiency Diesel Engine VII (CHEDE-VII) Consortium began in November 2015.

This program is pursuing the world's most efficient engines to meet the needs of industry 5 to 10 years into the future. The four-year multi-client consortium includes consideration of worldwide markets and technology impacts on each. Goals include research and demonstration of technologies to achieve 55% engine-system efficiency.

  • HD diesel engine system goal of approximately 55% BTE at future low NOx standard
  • LD diesel engine goal of providing a low cost effective, clean LD Diesel at 2025 GHG

CHEDE-VII Three Main Areas of Concentration

  1. Low NOx + Low CO2 Heavy Duty Diesel Engine
    Goals:  Research and demonstration of technologies to achieve 55% engine-system efficiency that meets future low NOX emissions standards (engine goal ~50% BTE, plus waste energy recover =55% BTE total)
  2. Alternative Combustion Technology
    Goals:  Evaluation and demonstration of new and alternative combustion systems. Topics include advanced dual-fuel engine technologies, smokeless diesel combustion, and gasoline compression ignition. Project goals to demonstrate potential engine efficiency and emissions improvements from alternative combustion technology.
  3. Cost Effective, Light Duty Diesel
    Goals:  Multiple paths that include cost effective LD diesel system, opening new potential for diesels in LD gasoline markets (drive-cycle efficiencies 10% better than premium gasoline), emission solution to meet U.S. SULEV, and CO2-minimized diesel for Euro-VI and beyond.
