A highly efficient low-emission co-generation system using a 2000-cc common-rail direct-injection (CRDI) diesel engine with an after-treatment device (re-combustor) was developed. The co-generation concept was utilized to produce electric power by a generator as well as to recover waste heat from the exhaust gases. A re-combustor was installed at the exhaust gas outlet to perform secondary burning of the exhaust gases, resulting in an improvement of the system’s thermal efficiency as well as a reduction of exhaust gas emissions. The main components of the re-combustor were coiled Nichrome wires installed in a ceramic housing, a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF). The tests were conducted at four water flow rates (10, 15, 20, and 25 LPM) and four electric power outputs (5, 15, 25, and 35 kW). In general, a great deal of time and expense are required to determine the optimum experimental conditions for the maximum efficiency of a co-generation system. However, in the present study, relationships between experimental conditions were derived by performing only a minimal number of experiments, applying a method based on Taguchi design and analysis of variance (ANOVA). The results show that at a water flow rate of 20 LPM, an electric load of 25 kW, and a ceramic heater input of 4 kW, the system achieved a maximum total efficiency of 85.7%.
