Video about the Clean High-Efficiency Diesel Engine VI Consortium
Building on the more than 20 years of the industry's longest running diesel research consortium, the Clean High-Efficiency Diesel Engine VI (CHEDE-VI) Consortium began in November 2011.
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
- Engine goal of approximately 48% BTE
- Plus waste energy recovery of 55% BTE total
CHEDE VI Three Main Areas of Concentration
- Advanced Heavy-Duty Engine Research
Goals: Research and demonstration of technologies to achieve 55% engine-system efficiency (engine goal ~48% BTE, plus waste energy recover =55% BTE total)
- Advanced Non-Road Engine Research
Goals: Engine efficiency improvements of >10%, to achieve ~45% BTE with engine technology to allow simplified aftertreatment, robustness to off-road operation, strong transient capability, and cost effectiveness.
- Advanced Light-Duty Engine Research
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.
Specific Clean High-Efficiency Diesel Engine Research Areas
- Combustion systems
