Energy Scavenging in a Vehicle’s Exhaust System

Abstract

Present-day development of power transmission systems, especially the ones based on combustion engines, is trying to cope with the issue of improving the energy efficiency of energy processing systems. One of the directions is to use the techniques of thermal energy recovery from an engine's exhaust system. Vast part of the energy produced while burning the air-fuel mixture is lost in the cooling and exhaust systems. Research in this area was conducted by numerous teams, both abroad and in Poland, while focusing on use of Peltirea cells. The results of their research demonstrated small efficiency of these cells. In this paper, the authors have focused on modifications of the exhaust system in order to improve heat exchange between the exhaust system's elements and TEG.

Advancements in Thermoelectric Generator Design: Exploring Heat Exchanger Efficiency and Material Properties

“…Hilali and Talbi both present experimental applications of engine exhaust gas-driven cooling systems, with Hilali focusing on an absorption refrigeration system and Talbi on a turbocharged diesel engine and absorption refrigeration unit combination [14,15]. Lubikowski explores the potential for energy scavenging in a vehicle's exhaust system, mainly through thermoelectric generators [16].…”
