Thermochemical Heat Storage For Consumption Reduction In IC Engines

Cover Story December 2019 Vienna University of Technology Austria Thermochemical Heat Storage Consumption Reduction IC Engines

A modular thermochemical heat storage prototype, developed at the Institute for Powertrains and Automotive Technology, Vienna University of Technology, was integrated in the coolant circuit of an SI engine for passenger cars

The aim was to analyse the basic suitability of the system as well as the potential for reduction of fuel consumption through storage of engine waste heat. The functionality of the system was confirmed in the framework of the conducted driving cycles – it has been proven that improvements of energy density and power release are needed for an effective series application.
