2017 by Taylor & Francis Group, LLC. This section discusses the two most common reciprocating internal combustion (IC) engine types in current use: the spark ignition (SI) and the compression ignition (CI or Diesel) engines. Space limitations do not permit detailed coverage of the very broad field of IC engines. For a more detailed treatment of SI and CI engines and for information on variations, such as the Wankel rotary engine (Norbye, 1971) and the Miller cycle engine (a variation on the reciprocating four-stroke engine), several textbooks, technical papers, and other sources on the subject are included in the list of references.
