Summary

Hydrogen will become an important energy carrier of the future. It can be produced from renewable electricity and can be stored and transported as gas, liquid and in hydrogen derivatives. For on-road mobility applications, hydrogen will contribute to well-to-wheel and life cycle CO₂ neutral solutions. Important automotive markets, e.g. China, United States, EU, Korea and Japan have already started and will accelerate the build-up of a hydrogen refueling infrastructure.

Following a technology open approach, and complementary to fuel cells, hydrogen engine powertrains are considered as a potentially attractive solution. For passenger car applications, the integration of hydrogen engines into hybrid powertrains is of particular interest because it creates significant functional benefits. A joint research between Aramco, Bosch and Hyundai Motor Group is established to investigate within a demonstration project the potential of such a system.

This paper presents the hydrogen adaptation of the combustion system for a 1.6 l turbo-charged Hyundai mass production gasoline engine. It includes the simulation-supported alignment of hydrogen specific components, the integration of hydrogen subsystems as well as an empowered charging concept to enable the lean burn combustion. The results demonstrate feasibility and attractive characteristics of hydrogen engine powertrains for future passenger cars.
