Basics of Internal Combustion Engines PD730944

In your profession, an educated understanding of internal combustion engines is required, not optional. This course covers the most relevant topics for maximum comprehension, from the chemistry of combustion to the kinematics of internal components of the modern internal combustion engine. You’ll gain a practical, thorough 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. The course also includes the design theories that embody these concepts.

This ten-hour course is comprised of twelve modules that include the instructor’s insights and industry experience working with internal combustion engine design and application. The modules cover various topics including (but not limited to), two- and four-stroke cycles, principle operational differences of various fuels, timing and working relationships among internal components, limitations to current designs, and the evaluation of new designs.

While the course is approximately ten hours in length, the estimated time to completion, including knowledge checks and the learning assessment is eleven hours.
