Clean Combustion Engine Laboratory

University of Windsor, Windsor, Ontario
What the facility does

The laboratory conducts high efficiency clean combustion engine and hybrid powertrain research.

Areas of expertise

The Clean Diesel Engine Laboratory (CDEL) at the University of Windsor was founded in 2003. Since 2009, the state-of-the-art facilities in CDEL have been further enhanced through CFI-ORF support, resulting in an advanced engine research lab. As the director of CDEL, Dr. Ming Zheng has led his research team in establishing advanced engine research platforms and has engaged in many innovative research projects that target sustainable heat engine development to improve engine combustion efficiency and to reduce pollutant emissions.
