Engine Valvetrain Design Series

Learn the fundamentals of IC engine valvetrain systems and how they are designed to control the Internal Combustion Engine Air System for power, emissions and improve fuel economy. These skills and tools will have immediate and long term benefits to workplace engineering decision-making and problem-solving.

• Engineers involved in performance, combustion, air handling, and emission control development of diesel or spark-ignition engines
• Engineers having responsibilities in engine design or mechanical development, whose work includes aspects of camshaft, cam drive, or valvetrain layout and development
• Engineering managers whose responsibilities include engine design, mechanical development, or engine performance, combustion, and emission control
• Engineers and managers in supplier companies supporting performance, combustion, and emission control
• Controls engineers involved in fuel system, aftertreatment and air handling control who would like to gain a greater understanding of the air handling system in spark-ignition or diesel engines
• Vehicle application engineers whose responsibilities include engine air handling, or aftertreatment systems

This course is an Anytime course which is structured to duplicate the in-person course plus additional learning quizzes. The full course consists of five individual courses in the Engine Valvetrain Design Series and provides a significant discount over taking individual courses. In addition, a full course notebook will be shipped to you after registering whereas this option is not available for the individual courses. Please see the course outlines and overview links below for additional information.  NOTE: For shipping outside of the USA, the student is responsible for paying the shipping fee of the course material binder.
