Diesel Emissions and Their Control

Magdi Khair is a staff engineer in the Department of Emissions Research at Southwest Research Institute. He received his B.S. in Automotive Engineering from Am Shams Univ.; his M.S. in Thermodynamics from the Univ. of Birmingham; and his M.B.A. from Michigan State Univ. Mr. Khair is experienced in the areas of engine testing from exhaust emissions control. His prior experience was with AlliedSignal Automotive Catalyst Co. with the development of catalytic aftertreatment for light-duty and heavy-duty diesel engines; Ford New Holland with primary responsibility for the development of the 6.6 and 7.8 liter midrange diesel engines to meet 1991 emissions standards; Bendix Diesel Engine Controls where he led the development of advanced electronically controlled diesel fuel injection systems and also established several cooperative engineering programs with European and North American engine manufacturers; and with Chrysler Corp. where he converted the slant six gasoline engine into an open chamber, pilot injected and electronically controlled diesel engine, supervised a combustion kinetics project, and participated in the design and development of electronic controls for a passenger car turbine engine. Early in his career, Mr. Khair had professional assignments at Nasr Automotive Mfg. Co., Egypt, and John Brown Engineering Ltd., Scotland. His experience includes extensive engine emissions testing, calibration of fuel injection systems, development of intake manifolds, optimization of intake ports, and development of electronic engine controls. Mr. Khair holds 13 U.S. patents in electronic fuel injection, turbocharging, exhaust gas recirculation, and aftertreatment systems. He has authored and co-authored numerous SAE and ASME papers and is a popular instructor of SAE’s Diesel Engine Technology Seminar.

Addy Majewski holds a Ph.D. in Chemical Engineering from the Wroclaw University of Technology, Poland. He worked at the University in areas of heat transfer and heat exchangers, evaporation, distillation and absorption with chemical reactions. Since 1991 he has lived and worked in Toronto, Ontario, Canada. His work experience includes development of diesel particulate filters and emission control catalysts for diesel, LPG and natural gas engine applications. Currently he is the president of Ecopoint Inc., a consulting firm that specializes in engine emission control technologies. He is also the founder and editor of DieselNet.com, an internet-based technical information service on clean diesel engine and emission technologies. Mr. Majewski is a member of the Society of Automotive Engineers (SAE), and a professional engineer in Ontario.
