Diesel Engine System Controls

epd.wisc.edu/RA01637 See upcoming dates

Course Overview

This course will help you understand engine system control requirements, basic architecture, and strategies used in the control system. You’ll become familiar with controls terminology and the development process that is used to meet engine system requirements, and develop an appreciation of transient behavior and dynamic coupling in an engine system. 

Who Should Attend?

  • Engineers, managers, technical and program managers with backgrounds in systems, mechanical, electrical, or industrial engineering who are involved in vehicle powertrains, sensors/actuators, and diagnostics
  • Test engineers and technicians
