Diesel Engine Technology

I.D. #

93014

Duration

2 Days

As diesel engines become more popular, a fundamental knowledge of diesel technology is critical for anyone involved in the diesel engine support industry. This course will explain the fundamental technology of diesel engines starting with a short but thorough introduction of the diesel combustion cycle, and continue with aspects of engine design, emission control design, and more. An overview of developing technologies for the future with a comprehensive section on exhaust aftertreatment is also included.

The text, Diesel Emissions and Their Control, authored by Magdi Khair and W. Addy Majewski is included with the seminar.

Learning Objectives

By attending this seminar, you will be able to:

Summarize the technological advances in modern diesel engines
Evaluate the sources of emissions from diesel engines and the influence of engine component design on curbing these emissions
Explain diesel exhaust aftertreatment systems and their effectiveness in reducing emissions
Recognize the importance of fuel injection parameters to performance and emission control

Who Should Attend

You should attend this seminar if you are involved in diesel engine support industries such as catalytic converters, lube oils, gaskets, and turbocharger suppliers, and if you are not well versed with diesel engines although they play a major role in your career's survival.

Instructor(s):

Magdi Khair

Dr. Magdi Khair currently holds the position of Chief Technologist at Watlow, where he is assisting with the introduction of new technologies for the diesel engine industry. Dr. Khair recently retired from the position of Institute Engineer in the Engine, Emissions, and Vehicle Research Division at Southwest Research Institute. He is experienced in the areas of engine testing and exhaust emissions control. His prior experience was with AlliedSignal Automotive Catalyst Company 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 Corporation 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. Dr. Khair holds 20 U.S. patents in electronic fuel injection, turbocharging, exhaust gas recirculation, and aftertreatment systems. He has also authored and co-authored numerous SAE and ASME papers. Dr. Khair is the co-author of the Diesel Emissions and their Control a text book marketed by SAE. Dr. Khair received a B.S. in Automotive Engineering from Ain Shams University, an M.S. in Thermodynamics from the University of Birmingham, England, an M.B.A. from Michigan State University, and a PhD in Engineering Management from Warren National University.
