The Basics of Internal Combustion Engines

In your profession, an educated understanding of internal combustion engines is required, not optional. This two-day technology survey seminar covers the most relevant topics - ranging from the chemistry of combustion to the kinematics of internal components of the modern internal combustion engine - for maximum comprehension. Attendees 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.

What Will You Learn

By attending this seminar, you will be able to:
  • Discuss in detail the basic functioning and component interaction in a modern internal combustion engine, specifically; two and four-stroke cycles as they relate to reciprocating and rotary engine designs
  • Describe the general thermodynamic concepts governing the operation of an internal combustion engine and its various cycles
  • Compare the principle operational differences of the various fuels used in internal combustion engines, their availability, and understand the applicability of each
  • Discuss the function and operation of all major components and systems within a modern internal combustion engine
  • Identify the operational principles behind the timing and working relationships among all internal components, and articulate the importance of this inter-relationship
  • Recognize the limitations of the current designs and implementations of the modern internal combustion engine
  • Perform a basic assessment and evaluation of new, cutting-edge designs and new powertrain initiatives as they apply to the mobility industry

Is This Course For You

Designed for powertrain engineers, component suppliers, vehicle platform powertrain development specialists, and those involved in the application, design and discussion of engines. It is recommended that seminar attendees have an undergraduate engineering degree.
