Current/recent research projects:

Diesel particulate emissions measurement and control. A copper additive in conjunction with a ceramic particulate matter trap is being studied relative to its effect on emissions and the regeneration process in the trap. A new silicon carbide trap material is being used for the research. The emissions are measured relative to their size distribution, chemical and biological character.

Diesel particulate and gaseous emission measurement and control in underground mines. Advanced tailpipe and ambient measurement methods are being applied to various mines using diesel particulate traps and oxidation catalysts to determine the control efficiency of the technology in the mine environment.

Vehicle Cooling System Simulation Model. A detailed thermal model of the cooling system of a heavy-duty diesel vehicle is being developed to simulate the complete engine, radiator, oil cooler, the air to air intercooler and the controls of the vehicle.
