Abstract Building


Under scientific and technical development for almost two decades, the i-Phi™ (innovative Partial hydrogen injection) is the only hydrogen injection system on the market that has been proven effective in reducing fuel consumption through aspirating the correct amount of hydrogen along with oxygen into the engine air intake, which results in enhanced combustion, reduced maintenance requirements, all the while reducing emissions and helping green the planet.


The i-Phi™ technology is versatile, safe and requires low maintenance. At the same time, it is scalable, efficient and cleaner.

The i-Phi™ system is a bolt-on device that works on any large diesel engine, where hydrogen and oxygen is being injected into air/fuel mixture for better combustion. It operates only when engine is running and it is completely safe, since no hydrogen is stored in the unit.

Low maintenance is given due to the fact that it only requires addition of small amounts of distilled water.

On larger engines it is possible to link multiple units together. Even though only tiny amounts of hydrogen are injected, the combustion is quicker, cleaner and more complete with hydrogen. Based on most user experience, i-Phi™ technology provides greater engine power with no black smoke.


Beside increased horsepower and torque, less maintenance (extending the intervals between oil changes, diesel particulate filter (DPF) maintenance, exhaust gas recirculation (EGR) maintenance, reducing diesel exhaust fluid (DEF) consumption and longer engine life expectancy) and reduced fuel consumption, which all together mean significant cost savings, our i-Phi™ technology provides even greater environmental savings:

  • Decreased carbon dioxide (CO2) emissions by 15%+

  • Decreased smog producing Nitrogen Oxides (NOx) by 30%+

  • Reduction of particulates that release soot and black smoke by 80%+

  • Reduction of Total Hydrocarbons (THC) by 15%+

We can help you achieve your environmental goals and Environmental, Social, and Governance (ESG) ratings and with our Green Print Assessment, we can also help you calculate your carbon savings so you can earn Carbon Credits to use or sell.

Another great benefit of the IHS i-Phi™ system is its flexibility and scalability. Units can provide hydrogen on demand for a single application on an engine, applications for multiple engines or for larger engines. For larger engine applications, multiple units can be installed to generate the appropriate hydrogen level for the engine to receive maximum benefits. Our engineering team can adapt the patented i-Phi™ technology to virtually any internal combustion engine to produce fuel savings and emission reductions.

i-Phi Benefits


This technology has been verified by several third parties including Wardrop Engineering, Clean Air technologies, Global MRV, Jomini Environmental Inc. and Auburn University. Scientists, engineers and fleet owners have documented these improvements. Simply put, when the right amount of hydrogen is injected at the right time into your engine, only through the engine’s air intake the combustion is quicker, more complete and cleaner than without hydrogen. Hydrogen is the purest combustible substance on earth. It is far cleaner and more powerful than diesel.

Third Party


With a long history in the Heavy Goods Vehicle market such as Trucks, Buses, Locomotives, etc., the i-Phi™ has achieved double digit fuel savings in all climates utilizing our unique thermal management technology.

In the case of diesel generator engines (Genset), the unit is customized to the environment to maintain the unit at the optimal operating temperature (heat or cold) along with custom water reservoirs and feed systems to accommodate longer run times.

For Marine diesel engines, the unit will include a custom cooling and water feed system to deal with the extreme heat of an engine room. In addition, the unit is designed to meet international marine specifications for all hoses, connections and fittings.
