High Efficiency Combustion Systems With the increased demands for fuel efficiency and fuel economy, the internal combustion engine (ICE) continues to be examined for design enhancements to improve these measures. Overall, the program will examine several technological advances required to maximize efficiency, including: o Advanced, low-temperature combustion techniques o Improved understanding and modeling of heat loss mechanisms o Electrification and intelligent control of accessory loads o Possible redesign of mechanical systems (e.g., variable stroke for fully expanded cycles) o High-efficiency turbo-machinery to extract exhaust energy and provide boost Emissions Reduction With a greater than 10 percent growth expected in the domestic passenger vehicle market, China now has the world’s largest auto market; and emissions from transportation are growing rapidly as well.

The ability to quickly and accurately model vapour cycle systems is of increasing interest to a diverse range of industrial applications where energy is lost in the form of ‘waste heat’ from a combustion process. This is especially the case for the Organic Rankine Cycle (ORC), which has long been associated with Combined Heat & Power (CHP) plants and small-scale power generation due to its ability to recover heat from relatively low grade engery sources such as biomass, geothermal and solar. However, vehicle manufacturers are also realising the opportunity of recovering some of the 60-70% of fuel energy that is normally lost to the surroundings. Indeed ORC systems are particularly well suited to recovering heat from the vehicle’s exhaust, or liquid cooling system. The recovered energy is used to heat the working fluid to a superheated vapour which is then expanded using either a turbine or a postive displacement machine to extract useful work.
