Automotive Thermoelectric Generator impact on the efficiency of a drive system with a combustion engine

Abstract

Abstract. Increasing the combustion engine drive systems efficiency is currently being achieved by structural changes in internal combustion engines and its equipment, which are geared towards limiting mechanical, thermal and outlet losses. For this reason, downsizing. In addition to these changes, all manner of exhaust gas energy recovery systems are being investigated and implemented, including turbocompound, turbogenerators and thermoelectric generators. The article presents the author's idea of a thermoelectric generator system of automotive applications ATEG (Automotive Thermoelectric Generator) and the study of the recovery of exhaust gas energy stream. The ATEG consists of a heat exchanger, thermoelectric modules and a cooling system. In this solution, 24 commercial thermoelectric modules based on Bi 2 Te 3 (bismuth telluride) were used. Measurements were made at two engine test sites on which SI and CI engines were installed. The exhaust gas parameters (temperature and mass flow rate), fuel consumption and operating parameters of the ATEG -the intensity and the voltage generated by the thermoelectric modules and the temperature on the walls of the heat exchanger -were all measured in the experiments. Based on the obtained results, the exhaust gas energy flow and the power of the ATEG were determined as well as its effect on the diesel engine drive system efficiency.

The Electrochemical Stability of Starch Carbon as an Important Property in the Construction of a Lithium-Ion Cell

“…Energy storage devices used in alternative drive vehicles are also recharged during the operation of the vehicle with the energy generated during the recuperation process. An example of the analysis of the balance amount of the exhaust energy recuperation process is the publication by Ziolkowski A [ 48 ]. The author presented his own design of an ATEG thermoelectric generator for automotive applications and made measurements to determine the amount of recovered electricity.…”

Study of Thermoelectric Generator Utilization to Recover Heat at Low Temperature Grade Application: A Review

“…From the fuel energy supply at ICE, it is only 25% that convert to power output for driving (see figure 4). Majority of fuel energy is indicated as an energy loss to surrounding that dissipated as waste heat through engine exhaust [22]., Several researchers have worked to optimize the ICE system by recovering the waste heat from engine exhaust using thermoelectric to optimize the system, produce power and reduce the emission. They named it ATEG application (Automotive Thermoelectric Generator) as a combination device between thermoelectric and automotive heat exchanger equipment.…”

Experimental study of the potential for thermal energy recovery with thermoelectric devices in low displacement diesel engines

“…However, the increased exploitation of ICEs is one main driver of the accelerated depletion of fossil fuels and the large emissions of greenhouse gases and other pollutants [6,7,8,9]. Commercial vehicles represent around 38% of the global consumption of fossil fuels [10] while accounting for 16.4% of the global emissions of CO 2 [11,12].…”
