Abstract

On the global race to reduce CO2 emissions solutions for road traffic play a major role. Vehicles with hydrogen internal combustion engines can be operated CO2 free and with optimized combustion and exhaust aftertreatment also achieve zero impact emissions.
Powertrain systems with highest efficiency are needed. To keep the energy for hydrogen production on the lowest level and to increase the range of the hydrogen fueled vehicle. Future passenger cars powertrains will be electrified and therefore allow a specific hydrogen engine layout: A dedicated hybrid engine. For commercial vehicles hybridization will have a significant lower market share, which means that efficiency increases cannot use electrification in the same extend.
This publication deals with the layout of hydrogen engines for passenger cars and commercial applications with highest efficiencies also for hybridized powertrains.
