Performance Characteristics of a 10㎾ Gas Engine for Generation Package

Cogeneration has been widely introduced in many countries for use in industrial, commercial and residential applications. However, there have been few models with an output of less than 100㎾. In the present study, a spark ignited gas engine with electric generation output of 10㎾ was developed for micro cogeneration package. Developed gas engine achieved following performance characteristics such as 26.7% of electric generation efficiency, NOx emission less than 10 ppm at 13% oxygen, 82㏈ of noise level, and about 3 seconds of switching time from idling to nominal power.
