PATENTED  (2018) Hydrogen Fuel systems   – Background – Hydrogen Generator kits

About Us  hydrogenfuelsystems Hydrogen Generator kits.

Gavan Knox is a professional Physics and Chemistry Teacher in West Australia/ Scientist /  Inventor  / university researcher with 35+ years experience. Gavan is  qualified with a Bachelor of Physics, Engineering, Chemistry, Education (Chemistry/Physics) and is currently studying to complete his Masters in Chemical engineering (metallurgy).  Hydrogen Fuel Systems Pty Ltd specializes in alternative energy systems for use in internal combustion engines.   The aim is to improve the Fuel efficiency, Power output and Torque of an engine as well as reducing the toxic polluting gases produced by internal combustion engines. As a parent of 6 wonderful children, I feel a need  to do my best to help stop global warming  by promoting the use of Hydrogen technology worldwide.  My company has sold a large volume of hydrogen systems worldwide. As more and more people realize the savings that are achieved by using our systems My inventions greater impact  worldwide.  In China My systems are widely accepted and used on transport Vehicles for  their effectiveness in reducing pollution and increasing engine efficiency.

Fuel Savings

1-This investigation establishes that hydrogen can be utilized in compression ignition engines operating them on dual-fuel principle.
2-Such operation improves Chemical  thermodynamic efficiency, makes the engine run with very lean equivalence ratios, which means very low engine emissions.
3-This operation results in lower exhaust gas temperatures leading to longer live of components such as exhaust valves.
4-Increasing hydrogen volumetric fractions accompanied with injection timing retarding, due to increasing in the flame velocity till the air is completely utilized. Excessive increase in HVF (Hydrogen Fraction) causes knock to appear, and OIT (optimum injection timing) must be retarded sharply, which reduce the bp resulted from engine.
 At optimum HVF  engine knock reduce and therefore Engine  perforance , BHP and efficiency markedly increase.    Introducing Hydrogen increases the CR  (compression ratio) significantly and therefore increases the Brake Horse Power for the Diesel engine (http://www.ijerd.com/paper/vol9-issue3/A09030109.pdf).
5-Knocking in the engine limits the proportion of energy input that can be supplied through hydrogen. The occurrence of knock in this type of hydrogen addition operation may be due to hydrogen rapid rate of pressure rise or flaming particle that is left behind due to bad engine scavenging.
6-When engine was run with hydrogen addition, bp was improved. The effect of hydrogen addition on the power enhancement was both quantitatively and qualitatively by the means of combustion improvement

Using hydrogen injection into a diesel, petrol or LPG fuelled engine results in significant fuel savings, by:

1. Allowing a leaner air/fuel mixture.

2. By more thoroughly burning all the fuel introduced into the engine.

3. By increasing the power output of the engine, increasing the efficiency of the engine thereby reducing the “throttle “ setting required to achieve the engine speed and vehicle speed

4. Ensuring the valves, piston head and cylinder head is free of carbon buildups , which would otherwise interfere with the air/fuel flow in the cylinder and reduce engine efficiency.

5.  Hydrogen gas significantly increases the rate of combustion of the fuel ( due to the incredibly fast flame speed which is  600 times that of diesel and petrol).  Consequently, the entire fuel charge is burnt at or close to top dead centre on the power stroke. Having fuel burn at the bottom or near the bottom of the expansion/ power stroke of an engine, is a pointless procedure.  Consequently more power is delivered by the engine having the fuel charge burn at TDC (Top Dead Centre)  and allowing the expanding gasses to deliver power more efficiently to the engine.

6.  Hydrogen also allows increased compression ratio because of the ability of hydrogen rich gas to prevent knock (high octane).

7. The brake thermal efficiency is greatly improved with the addition of hydrogen, especially at lean conditions.

Cleaner Emissions

Hydrogen Generator kits

– Using Hydrogen injection into the engine the fuel is “ flashed” at a much higher temperature allowing the fuel to burn more completely. A leaner fuel mix ensures a more complete combustion process resulting in less unburnt or partly burnt fuel/ hydrocarbons being passed out the exhaust.

Cleaner Engines

Hydrogen generator Systems

– By having a more thorough combustion process there is less wasted fuel producing buildups / coating on the valves, pistons and cylinder heads. The contaminants of incomplete combustion mean the lubrication fluids remain cleaner and in better condition for engine lubrication.

What Drives Us


As an West Australian Physics and Chemistry teacher /  research Scientist for the past 35 years I have  attained knowledge which I use to develop a alternative fuel system to help reduce the environmental stress on our fragile planet. As a parent of 6 children , I  put my education to use into working  to protect the environment my young family will inherit. I see that reducing pollution due to the incomplete combustion of fossil fuels is a major risk to my childrens planet and lifestyle. Furthermore this pollution problem can be rectified by introducing Hydrogen fuel technology.  Over the past 10 years  my HFS systems are  internationally  accepted and used.   HFS systems will  provide the people of the world with:

a)  a better fuel supply option  ,

b) a safer option,

c) a cleaner option and

d) a cheaper option than indiscriminately burning fossil fuels….

e) a more reliable fuel supply than the petro-chemical industry

f) hydrogen for producing electricity using hydrogen fuel cell technology to improved coal fired generator systems – which use a patent pending innovation involving hydrogen and exhaust gases from burning coal to have  less pollution and more available energy
