Abstract

The work presents experimental results of performance tests and theoretical calculations for the thermoelectric generator TEG mounted in the exhaust system of a 1.3 dm3 JTD engine. Benchmark studies were carried out to analyze particularly the problem of the influence of back pressure of exhaust gases, caused by the heat exchanger of the TEG generator, on the efficiency of the entire driveline. The detailed study was performed using a new prototype of the thermoelectric generator TEG equipped with 24 BiTe/SbTe modules with the total nominal power of 168W. Both experimental and theoretical results show that at certain conditions flow resistance losses can be comparable to the energy produced by the TEG. In order to describe the actual efficiency of the whole TEG-based waste recovery system we propose to introduce a new parameter – net efficiency Nnet
