As diesel engines become more popular, a fundamental knowledge of diesel technology is critical for anyone involved in the diesel engine support industry. The SAE Diesel Engine Technology e-Seminar, featuring Instructor Magdi Khair, will explain the fundamental technology of diesel engines, starting with a short but thorough introduction of the diesel combustion cycle, and continuing 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 nearly thirteen hour course is divided into an introduction and eight modules. The instructor makes reference to his book, Diesel Emissions and Their Control, co-authored with W. Addy Majewski and also available from SAE International.
Major topics include:
