Engine - Four-Cycle Theory is part 17 of the Dresser-Rand Reciprocating Products 19-part training series.
This intermediate-level course gives students a comprehensive understanding of the theory of four-cycle gas engines. The course begins with a brief review of components specific to four-cycle engines and how they differ from those used in two-cycle gas engines. A basic introduction to combustion theory and the natural gas laws follows. Once students are familiar with these important concepts the course proceeds to describe the two-stroke cycle process in detail through the use of P-V and P-T diagrams and animations.
