Hydrogen is widely regarded as a promising transportation fuel because
it is clean, abundant, and renewable. In a gaseous state, it is
colorless, odorless, and non-toxic. When hydrogen is combusted with
oxygen, it forms water as the by-product. Due to hydrogen’s
high flammability range, it can be completely combusted over a wide
range of air/fuel ratios.
However, like other gaseous fuels, the delivery
of hydrogen into an engine’s intake by conventional fuel injection
techniques leads to a displacement of the vital air needed for full
load performance. This loss in volumetric efficiency can be overcome
by the use of direct injection technology. The challenges for the
hydrogen researcher do not end there. Whilst direct injection improves
the pre-ignition behaviour over cabureted and port injection schemes,
in-cylinder combustion know how is a prerequisite.
Orbital’s direct injection combustion
know-how, advanced combustion development facilities and streamlined
analysis techniques mean that you will partnering with someone who
has decades of DI experience.
