PROPULSION | MANUFACTURING FEATURE
and direct injection. This solution is particularly suitable
for heavy-duty vehicles on long hauls with especially
heavy loads.
" A hydrogen engine can do everything a diesel engine
does, but on top of that, it is carbon neutral. This
is a quick and cost-efficient way into the mobile use of
hydrogen, " Heyn said, adding that more than 90% of
the engineering and manufacturing technologies
needed for it already exist.
Many of the systems components in existing powertrain
solutions can be transferred to the fundamental
structure of the fuel, air-supply and exhaust systems.
While the H2
ICE still emits NOx, proven exhaust-gas
treatment systems work to allow " no appreciable effect
on air quality, " according to Bosch.
" The biggest technological challenge is the injector
for direct injection, " Heyn explained. " Unlike in a diesel
engine, it has to work without any lubrication from the
fuel, and yet, just like in a diesel engine, still be capable
of opening and closing billions of times over.
Our engineers are in the process of solving this problem
without any additional oil being emitted. Nobody
else in the world has managed this so far. "
The first production vehicles equipped with these
More than 90% of the engineering and manufacturing technologies needed for the
H2
ICE already exist, Heyn said.
engines are expected in 2024. Bosch currently has four orders for
production projects from various regions and expects six-figure unit
volumes by the end of the decade.
