The first product, scheduled to debut in April, is the key to everything else.
It’s called Internal Combustion Assistance (ICA), a
modification to internal combustion engines that enables them to
substantially increase their fuel efficiency and reduce their air
pollution. It does this by adding tiny amounts of gaseous hydrogen and
oxygen to the fuel just before it is combusted in the engine’s
cylinders. The HHO mix lends intensity to the combustion, allowing the
fuel to burn more completely, generating more oomph and less pollution.
The ICA system can technically work on any internal
combustion engine, but to begin with, HyTech is targeting the dirtiest
engines with the fastest return on investment, namely diesel engines —
in vehicles like trucks, delivery vans, buses, and forklifts, but also
big, stationary diesel generators, which still provide backup (and even
primary) power by the millions across the world.
