Among distributed power generation technologies, combustion engines (CEs) are the most mature prime movers. Advantages include comparatively low installed cost, high shaft efficiency, suitability for intermittent (start-stop) operation, high part-load efficiency, and high-temperature exhaust stream for combined heat and power (CHP). Additionally, a sales and technical support structure is already in place, parts are readily available and generally inexpensive, and service technicians (from both the dealer and customer’s staff) have experience with maintenance and repair. Figure 2.1 shows a typical CE-based generator set (genset). This chapter details not only traditional internal combustion engine generators, but also developments in external combustion, or Stirling, engines.
