Diesel Engine Technology Engineering Academy: Beyond 2020

This newly updated Academy covers diesel engine engineering principles relevant to the development, application, engine control and exhaust emission control of diesel engines for the next decade. The course will address how and why the engine that “powers the world” will continue to be relevant in the age of electrification including how electrification may benefit the diesel engine and its application. Course subject material will cover thermodynamic principles, combustion, modeling, in cylinder and aftertreatment exhaust emission control, diesel noise control, fuel injection systems, turbocharging/boosting, on-board diagnostics, lubricants and fuel requirements, and diesel engine applications. Evolving trends in the subject matter as well as new or revised innovative architectures and hardware will be addressed. It is an intensive learning experience comprised of lecture and structured practical sessions.

Hundreds of professionals from across Europe, Asia, and the Americas have benefited from the SAE Diesel Engine Technology Engineering Academy. This Engineering Academy has been the source for comprehensive diesel engine technology training. Professionals from companies like Infineum, Ford Motor Co., AVL, MAHLE, Robert Bosch, Komatsu, John Deere, BorgWarner, Eaton, Shell, Volvo, and numerous others have looked to SAE and the Diesel Engine Technology Engineering Academy for this technical training.

Practical Component
This Academy includes several practical activities, including team-based case studies or discussions, a technical tours and guest speakers. The course will be taught by a team of highly experienced professionals from industry and academia and led by an experienced engineer with a full and broad career in the diesel industry sharing experience and practical insight.

***Depending on the location of the Academy, please be advised this course may involve one or more of the following: driving and/or riding in a vehicle; participating in a vehicle demonstration; and/or taking part in an offsite tour using outside transportation. You may be required to sign a waiver on-site and produce a valid driver's license from your state/country of residence.***

Featured Technical Tours
This Academy will feature two technical tours where students will experience and reinforce lessons learnings in the classroom. Featured tours will be as follows:

Robert Bosch LLC
Robert Bosch LLC facility in Farmington Hills, MI will host a tour of their facilities where they perform advanced diesel fuel injection systems research. The tour will include the fuel-injection lab and engine dyno area. Students will experience live demonstrations of common-rail diesel fuel-injection technology in the lab, potentially in the dyno, and on a vehicle. The students will see how diesel fuel-injection equipment is characterized on a special test bench and see many of the operating principles that they learned in the Academy in actual operation.

University of Michigan Walter E. Lay Automotive Laboratory
The University of Michigan in Ann Arbor, Michigan will host a tour of the Walter E. Lay Automotive Laboratory. The tour will feature the engine test facilities; advanced engine configurations for research into fuels, aftertreatment, combustion chamber and valve timing design; and instrumentation for autoignition studies.
