focusing on hydrogen internal combustion engines as a
zero-emission technology since 2019. In addition to extensive
activities in the commercial vehicle sector, developments even
include a hydrogen racing engine presented in 2023.
The Internal Combustion Engine Is Becoming Climate-Friendly
By making use of the synergies between the internal combus-
tion engine and electrification, maximum efficiency levels of
up to 45 % can be realized in the car sector. In China especially,
AVL is strongly represented in the dedicated hybrid engine sec-
tor. We also offer solutions for regenerative fuels, and in the
commercial vehicle sector we are working on a hydrogen HPDI
engine that combines the advantages of diesel engines and
hydrogen. With this concept we were able to demonstrate an
efficiency level of more than 50 % for the first time in 2023.
Our current developments for high-speed large engines
include an innovative cylinder power unit with ignition pres-
sures of up to 330 bar: It enables the use of alternative fuels
and thereby contributes to the decarbonization of various
high-power applications.
For marine engines, for example, we rely on ammonia and
methanol produced regeneratively to meet the high range
requirements.
From Concept to Practical Application
AVL’s systems support current and future zero-carbon mobility
by means of simulation, test and measurement systems,
software, data analysis, as well as lab and workflow manage-
ment. Our testing solutions and virtual approaches – including
the Digital Twin in an SiL environment – facilitate rapid and
cost-effective development, testing, and measurement of
new propulsion technologies and concepts. Thus, we offer
modular, configurable, and extendable solutions for all types of
propulsion system and for all energy carriers.
“In a global environment,
ICE-based drivetrains
will continue to play an
important role as part
of the solution towards
sustainable mobility.
The crucial factor is a
fact-based openness to
technology.”
