摘要
We present herein a design for and performance measurements of a prototype thermoelectric generator (TEG) mounted on both a spark ignition engine (0.9 dm3) and a self-ignition engine (1.3 dm3). Using the prototype TEG as a tool, benchmark studies were performed in order to compare its parameters in terms of heat recovery from exhaust gases of both engine types. The test bed study was performed with an Automex AMX-210/100 eddy-current brake dynamometer. To provide a comprehensive overview of the TEG operating conditions, characterization of its parameters such as temperature distribution, heat flux density, and efficiency was done at engine speeds and loads similar to those within the range of operation of real road conditions.
