The Role of Alternative Fuels in
Next Generation Large Engines
Driving the Future:
s the global push for sustainable energy and
transTortation intensifies, alternative JYels tLat redYce
greenhouse gas emissions increasingly take center
stage. Among these, ammonia, methanol, and hydrogen stand
out for their remarkable potential to power large engines,
which play a crucial role in the shipping and power generation
industries. These fuels offer substantial emissions reductions
while maintaining performance and reliability. AVL has been
developing ammonia, methanol, and hydrogen large engines
for different market sectors for many years.
AVL Methodology
Despite the different fuel properties, safety concepts, and
sTecific reUYirements oJ eacL JYel, %:0 s YniUYe metLodology
in large engine development proves exceptional in minimizing
development time and costs while achieving high accuracy.
This methodology integrates single-cylinder engine (SCE)
tests with comprehensive simulation tasks and advanced
measurement techniques. Simulation is crucial in developing
large engines as their size often makes prototype production
impractical. The optimization of engine thermodynamics,
mixture formation, thermal load, NVH (noise, vibration, and
harshness), and many other tasks relies therefore heavily on
simulation. Continuous development of simulation tools and
methods enables AVL to provide the right solutions also for
carbon-neutral combustion engines.
