WASTE HEAT RECOVERY FOR COMMERCIAL VEHICLES: BASICS AND THE MAIN CHALLENGES

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Conventional propulsion systems for heavy duty trucks using internal combustion engines have evolved to a highly sophisticated level, reaching very good efficiency levels and thus quite low CO2 emissions. Nevertheless, recent development of world’s climate has made clear that even from the actual, refined technological level, further steps have to be made in order to reduce fuel consumption of the Diesel drive train.
One option, which has attracted more and more attention in recent times, is to use the “lost” heat of the engine being released into the environment unexploited via the cooling system and the exhaust gas. The usage of this barren energy, the so called Waste Heat Recovery (WHR), can be done via different methods, e.g. thermoelectrical elements, thermoacoustic machines or with Rankine cycles.
The paper gives a short overview of the different possibilities of WHR and their pros and cons; the Rankine cycle will be investigated in more detail, discussing the basic layout of the cycle, its components and the challenges that have to be faced, be in the design of the components, the selection of the working fluid, the build-up of the WHR system or its operation.
