The article reviews the fundamental phenomena (i.e. physics, chemistry, heat transfer, etc.) that interact within LTC engines, describes emissions characteristics and fundamental limits constraining maximum power output, and reviews promising strategies for extending the high power limits of these engines. The article is a valuable resource not only engine research experts, who will find a compiled comprehensive review of literature in the field, but also for students who are learning the basics of this engine technology.
