Pollution is a major concern for many IC engine manufacturers, as many Electric engines, taking over the Automobile industries, making a threat to IC engines, that’s one of the reasons, many manufacturers are turning towards improved injection systems solutions. for reducing pollution, and to have their place in their industries. This is where Hydrogen Technology comes into the picture, as it is quick to market propulsion solution that requires only slight adjustments to the traditional IC engines and Hydrogen Injection System takes its place as one of the system solutions.
So basically,
Hydrogen Injection System H.I.S is an onboard technology that injects
hydrogen in real time to reduce fuel consumption and polluting emissions in combustion
engines. It is a miniaturized, autonomous, new security system for combustion
improvisation, through electrolyzing of water or deionizing of water. It
greatly reduces the carbon impact and is suitable for all engine sizes.
H.I.S. is
estimated that it saves up to 25% of fuel and reduces 70% of pollutant
emissions. With reduced fuel consumption, the engine system gives excellent
Return on Investment (ROI) with increased performance and cleaner burns of
fuels. Many Tier companies are coming up with improvised hydrogen systems of
their own, so it is the OEM's decision to decide better Injection system to
improve combustion and reduce pollutant emissions.
Here are some
of the H.I.S. done by various Tier companies.
1.
Dual Fuel Marine Engine - MAN
The MAN
D2862 Dual Fuel engine is a proven V12 marine diesel engine. In that, hydrogen
is introduced into the charge air via an adapter and is added to the combustion
cycle. The combustion process is thereby started according to the diesel
principle, which requires the injection of approx. 5% of diesel fuel. The
diesel fuel common rail injection parameters have been optimized here for dual
fuel operation.
2.
Hydrogen Injection System -> BorgWarner
BorgWarner recently was its first hydrogen
injection system production program for an off-road application by a European
construction equipment manufacturer. Being in the field of injection systems for
years, they are actively working on hydrogen components for low, medium, and
high-pressure environments, and due to hydrogen’s lesser density than gasoline
and diesel, BorgWarner is also actively finding new solutions like port fuel
injection and direct injection solutions.
3. Low-Pressure Hydrogen Fuel
Injection System -> Liebherr
Liebherr is developing low-pressure direct
injection (LPDI) hydrogen fuel systems for combustion engines, mainly
concentrating on Heavy duty diesel vehicles from 7 to 100 liters in
displacements. The company focused on Injectors, which can be used as a part of a common rail system for spark-ignited engines or could also be a part of dual fuel systems. They incorporate a flexible blow cap design that allows for
different injection angles into the combustion chamber.
4.
High-Pressure Hydrogen Direct
Injection system –> UNSW Sydney
Engineers from UNSW Sydney have successfully converted a diesel engine into a hydrogen diesel hybrid engine, reducing carbon emissions by more than 85 percent in the process. The Hydrogen-Diesel Direct Injection Dual-Fuel System features independent control of hydrogen direct injection timing, as well as diesel injection timing, enabling full control of combustion modes – premixed or mixing-controlled hydrogen combustion, which kind of reduces nitrogen oxide emissions, which causes air pollution and acid rain.
5.
Hydrogen Gas Injector -> Bosch
Mobility Solutions
It is a compact proportional valve for Hydrogen gas
injection and is the main component in the hydrogen supply path in fuel cell
electric vehicles, when so requested by a control unit, the component injects the requested or necessary amount of hydrogen to the fuel cell system, with the
shutoff function for separating medium pressure stage from the fuel cell
stack.
