In-line with the growing interests in renewable fuels worldwide, this research team will, in close collaboration with industrial and academic partners, utilize the established research capabilities of the Clean Combustion Engine Laboratory (CCEL), to make significant progresses and breakthroughs on the enabling of ultraclean and efficient combustion in the advanced diesel and gasoline engines, especially when using the bio-source derived fuels. Extensive research has been performed at Windsor, to explore the compliance of the advanced hardware design and the combustion control strategies to biofuels and the other fuel property departures. Comprehensive air and fuel management strategies are developed to raise the fuel efficiency significantly and to cut the exhaust emissions drastically. However, the implementation concerns are yet to be fully addressed, and the control hurdles overcome, by new research efforts from the collective expertise of the collaborative partners. The technique of low temperature combustion, to which the Windsor group has a lead worldwide, are to be applied to the bio-ethanol and blends in combustion, via an energy and volume controlled ignition strategy that includes igniting by the adaptive arcing, diesel pilot, and other innovative ignition techniques. A cluster of unique corona discharge techniques have been explored at CCEL to present an ignition corona pulse-train of variable volume and duration that are suitable to ignite a lean and diluted cylinder charge, especially when using an alcohol fuel. Due to the polar structure of alcohol molecule, the application of corona ignition in a bio-ethanol mixture could possess significant advantage over the conventional fossil fuels such as gasoline and diesel. The advanced techniques of CCEL, i.e. the ignition control algorism of multi-fuel combustion and the multi-mode combustion controller including the corona system, will directly contribute the product innovations of the industrial partners, and broadly benefit the other worldwide engine manufacturers. The project aims at a fuel efficiency significantly exceeding that of the current gasoline engines, and an emission standard most stringent worldwide, in addition to directly benefit Canada and China.
