Internal Combustion Engine
Hydrogen is arguably the
ideal fuel since its use in internal combustion engines
produces only water.
The current political climate is such that most car
manufacturers are designing hydrogen fuel-cell cars and the
buzzword around the world is Hydrogen Economy. However, here
at Omnitek we believe that fuel-cell cars are many years away
and based on the tremendous cost and complexity of such
may never become a reality.
Even if fuel-cell cars make it to market, there are still several hundred million
cars in the world that are running on gasoline and diesel,
and continue to pollute.
Initially, it is more likely that gasoline and diesel fueled vehicles
will be converted to burn hydrogen. Vehicles with internal
combustion engines (ICEs) burning hydrogen is a practical
and achievable technology to serve as an interim step to
commercialization of fuel-cell vehicles.
The primary advantage hydrogen-fueled ICEs have over fuel-cell
vehicles is that it uses a proven and existing technology. Unlike
fuel-cell vehicles, which face daunting cost barriers and
technological challenges, hydrogen-fueled ICE vehicles could
be on the road faster. Hydrogen-fueled ICEs generally employ
various technologies, not unlike technologies developed for
vehicles burning compressed natural gas.
The Omnitek Hydrogen System and EMS can be retrofit onto gasoline and diesel engines
making it possible for these engine to operate on hydrogen
therefore becoming near-zero emissions vehicles (NZEV).
Electronic Engine Management System for
Hydrogen IC Engines
The key to this technology
is a sophisticated engine control unit (ECU) which senses
engine parameters in real time and instantly adjusts to
deliver the correct amount of Hydrogen and the correct
ignition timing. The system result in optimal engine
performance, while always operating at near-zero emissions.
The Omnitek EMS is easy to calibrate,
which guaranties a reduced time to go from prototype to
production. Engine manufacturers can even perform most of
the system integration in their own laboratory.
The system can be used to convert gasoline or diesel engines
to operate with Hydrogen. Many of the off-the-shelf sensors
and components used are readily available around the world.
A cost effective solution to some of the enormous air
pollution problems around the world.
The Hydrogen Engines
The Omnitek engine
management system can be used to convert gasoline or diesel
engines to operate with Hydrogen, however, in order to get
maximum performance and lowest emissions mechanical changes
to the engine should be performed. Changes to piston design
and the addition of forced induction (turbo or
supercharger), result in the biggest improvement to engine
performance. Improvements to the ignition system is
absolutely necessary in order to operate the engine in a
lean-burn state for best combustion control.
