Engine Valvetrain Design Series

Explore the fundamentals of Internal Combustion engine valvetrain systems and their critical role in controlling air systems for power and efficiency. Through detailed modules covering variable valvetrain systems, camshaft design, and failure analysis, participants will gain practical expertise to improve engine performance and compliance. Collaborative workshops and industry-driven discussions further enhance learning, providing a strong foundation for advanced engineering projects.

• Engineers involved in engine performance, combustion, air handling, and emission control development for diesel or spark-ignition engines.
• Engineering managers overseeing engine design, mechanical development, and valvetrain optimization projects.
• Controls and vehicle application engineers seeking deeper knowledge of air handling systems and aftertreatment processes in engines.

This course can be taken online anytime and offers maximum flexibility, allowing you to complete it online at your own pace. Designed to mirror the in-person version, it includes additional learning quizzes for an enhanced educational experience. The course consists of five individual modules from the Engine Valvetrain Design Series, and participants will receive a comprehensive course notebook shipped upon registration. Please refer to the course outline for detailed information.

Note: Students outside the USA are responsible for covering the shipping cost of the course material binder.
