Basics of Internal Combustion Engines

Basics of Internal Combustion Engines

A 2-Day Class

As a mobility professionalhaving a fundamental understanding of internal combustion engines is required, not optional.  This course covers the most relevant IC engine topics including the theory of ignition, the chemistry of combustion and the kinematics of internal components.  Learners will gain a practical, hands-on approach to the basics of the most common designs of internal combustion engines, as they apply to the gaseous cycles, thermodynamics and heat transfer to the major components, and the design theories that embody these concepts. 


Learning Objectives 

By completing this course, you will be able to identify, recognize or articulate: 

  • Basic functioning and component interaction in a modern internal combustion engine 
  • Thermodynamic concepts governing the operation of an internal combustion engine 
  • Operational differences of the various fuels used in internal combustion engines 
  • Function and operation of all major components and systems within a modern internal combustion engine 
  • Operational principles of the timing and working relationships among all internal components 
  • Limitations of the current designs and implementations of the modern internal combustion engine 


Who Should Attend 

The intended audience for this course is powertrain engineers, component suppliers, vehicle platform powertrain development specialists, and those involved in the application, design and discussion of engines.  



Learners should have an undergraduate engineering degree.
