drop in oil price and Hydrogen. April 22 2020 today , and no reported cases of COVID19 in Perth for the past 4 days. Social Distancing is working.

The recent Covid 19 crisis has had a significant effect on global pollution from reduced operation of Internal combustion engines. It has also affected the Hydrogen economy due to the sudden drop in the price of a barrel of oil the the point where is is now a negative value. THis has had a major impact on the promotion of hydrogen as a fuel .

drop in oil price and Hydrogen. Sales of hydrogen fuel systems has dropped significantly. Fortunately the excellent marketing of these systems before 2020 , means we are financially in a good condition . It has given us more time to look at ways of increasing the output and efficiency of the hydrogen generator systems as well as looking deeper into developing improved Electronic Fuel enhancer modules for diesel and petrol / gasoline fueled vehicles

We have further updated the power supply units so as to reduce wasted electrical energy ( as heat) and increase the gas production of these systems.

We have also developed a new electrolyte solution and dynamic pumping system that further increases the gas production output for a low current input.

The Power supplies use a patented schematic arrangement that is easily incorporated into old and new hydrogen systems to increase the gas output. Unfortunately at present we will not be showing photos of the electronic components until the patent is fully approved. The Pumping system we are using is a high power magnetic rotor pump that has high efficiency as well as having now rotor seals that leak and fail with age. With the new pulsating power supply system powering the pump and cells there is no wasted electrical energy making the solution heat up. This protects the magnetic impeller pump as Heat is the greatest problem with any magnetic assembly,

HHO GAS AS FUEL ADDITIVE

Introduction

Reducing the emission pollution associated with oil combustion is gaining an increasing interest worldwide. Recently, Brown’s gas (HHO gas) has been introduced as an alternative clean source of energy.

A system to generate HHO gas has been built and integrated with Honda G 200 (197 cc single cylinder engine). The results show that a mixture of HHO, air, and gasoline cause a reduction in the concentration of emission pollutant constituents and an enhancement in engine efficiency. The emission tests have been done with varying the engine speed. The results show that nitrogen monoxide (NO) and nitrogen oxides (NOX) have been reduced to about 50% when a mixture of HHO, air, and fuel was used. Moreover, the carbon monoxide concentration has been reduced to about 20%. Also a reduction in fuel consumption has been noticed and it ranges between 20% and 30%.

1. Introduction

Global warming is considered one of the major problems the scientific community has to face. Many theories refer to the in-crease of exhaust gases concentration in the atmosphere as oneof the major causes of the global warming [1]. Industrial plantsand automobiles are the major source of the exhaust gases.

Ground-Breaking Power supplies Massively Increase Hydrogen gas output

Ground-Breaking Power supplies. As part of our ongoing R and D I have dedicated time into improving the power supply and control modules which power the Hydrogen generator cell.

One of the issues of any electrolysis unit for mobile units is the available voltage and to a lesser extent the available current.

Current flow is essential to produce hydrogen  gas and using Faradays laws (1832) it is easy to calculate the amount of electrical current needed to produce a given quantity of Hydrogen gas.  Some of the “experts”  on free energy sites still believe that all they need is a resonant and a low current.  My definition of these “EX SPURTS” is that they are a “Drips” under pressure , – Pressure to prove they actually know somewhat more than a “demented earthworm”.

Excuse  my irritation on free energy morons and Getting back to the essential developments of this post….Power supplies

2 electrons are required for every molecule or hydrogen gas produced and electrical current is the flow of electrons through a conductor… 22 amp of current at 13.2 volts supplies enough electrons for a maximum of 0f 4.2 Litre of Hydrogen / oxygen  gas. Any less energy than that will reduce the gas produced.

When producing a DC power supply of fixed current , we have been conditioned to use electronic components such as constant current PWM devices.  There are several faults of such devices in control o fa DC current supply

  1. The electronics of the circuit introduces an internal resistance into the electrolysis circuit which reduces the available voltage for the unit and therefore the number of available cells that can be used for generating hydrogen gas. The REDOX potential for converting water into hydrogen and oxygen is 1.23 volts.  The internal resistance of the electrolysis produces a back voltage of 0.5 volt  and at least 0.5 volt overvoltage is required per cell to sustain a reasonable current flow through the cell. This equates to at least 2.2 volt is required to generate a useful supply of hydrogen gas from an electrolysis cell.  If we are using 6 cells then  we need 6 times 2.2 volt = 13.2 volt , to generate a reasonable supply of hydrogen gas. IF we have a PWM unit that is using 2 volts due to  internal resistance, that reduces our number of usable cells to 5 and drops the system efficiency by almost 20%.        Far too great a power / energy efficiency loss
  1. The PWM units are frequency modulated devices designed for use on DC motors designed to reduce back voltage loss due to reverse inductance and lenses law. This is not a motor and pointless using a complex frequency generating circuit that uses electrical energy in pretending to reach the resonant frequency of water. – which is several  giga-hertz not kilo-hertz as produced by commercial PWM devices.
  2. The High frequency PWM circuit forces the electrolysis cell to act as a capacitor , constantly charging and discharging and introducing a resistance known as Capacitive reactance.  Capacitive reactance is an internal resistance that uses more of the available input voltage , further putting a strain   on the voltage required for the OXIDATION / REDUCTION reaction producing water.

One solution to this situation is to run DC current into the system and control the current flow simply by the solution concentration. Sounds great but problem is

  1.  as the solution warms the resistance further falls and current flow increases exponentially overloading the vehicle generator/ alternator
  2. There is no effective control of the gas volume produced
  3. The electrolyte boils and steam is not what we want
  4. Thermal runaway changes the chemical thermodynamics of the electrolysis cells and the break down

So some form of circuit is required to limit the current without introducing a load onto the already voltage sensitive circuit.

With this in mind we have developed a relatively simple circuit that limits the voltage loss, does not produce a pointless high frequency output and yet still is able to control the voltage applied to the system so as to control the current flow and not lead to excessive heating of the electrolyte .

This circuit is simple and uses a number of Power FETS and their biasing potentiometers .   Extensive lengthy testing under a variety of temperatures has shown that this simple circuit is far superior , more robust and easier to use than the common PWM and constant current power supplies commonly used .

Hydrogen fuel systems have included this development into their patented design and manufacturing process.  A great advantage of this design is that it can easily and effectively be retrofitted to older systems currently being used  using PWM power controlling devices.

Because it  is patented process the exact schematics of the units will not be released …. Enough to say ,it is a design with will be incorporated  on all  future hydrogenfuelsystems    generator systems.

Fuel saver – frequency multimeter – Tuning Gen 10 Hydrogen fuel system

Fuel saver – frequency multimeter.  Over the  few years I have strived to optimize  the fuel efficiency of my V6 , 3.6 L engine through the use of my patented Hydrogen fuel system

We have achieved massive fuel savings and increased condition and longevity of the engine by using our patented Gen 10 Hydrogen fuel system on the vehicle. Today we Achieve savings of 47% on our family car which is very  satisfying, just using the Hydrogen system and an electronic fuel enhancer module that adjusts  the fuel map ,by adjusting the sensor signals from the following engine sensors

  1. Oxygen sensor

  2. Lambda Sensor

  3. Manifold air pressure sensor

  4. Coolant temperature sensor

  5. Intake air temperature sensor

In the case of the V6 commodore engine there is one other engine sensor which can be adjusted so as to improve the engine operating condition.  This is the Mass intake air flow sensor which is located just before the Throttle body assembly of the engine.  I have never adjusted this sensor as

  1. we have excellent fuel savings already and

  2. we did not have access to a meter which can be used to measure and adjust the Mass intake air flow (MAF) sensor sensor readings

However with the help of fellow university colleagues I made aware of a new device produced by an Australia-wide electronics company called JAYCAR electronics   –     called

Cat III True RMS Auto-ranging 4000 Count DMM with Temperature  Cat Number = QM1551

This device can be used along with our Mass air flow  (MAF) enhancer module to adjust the signal from the mass airflow sensor   on any  vehicle that has a frequency modulated sensor to measure and control and Mass air flow readings sent  to the engine ECU.

IN the past  ( before 2006), the sensors which measure air intake volume were simple Analog  / voltage based systems , and were able to be adjusted by simply putting a resistor in the circuit from the MAF sensor, but these Older style sensors were slow to react , inefficient and easily corrupted making the engine run in Limp Mode.

The Modern , improved and more stable MAF sensor used jn Europe, Australia and ASIA  were the frequency controlled MAF sensors , and now with the New Multimeter from JAYCAR  (Cat Number = QM1551) – It is easily adjusted to further improve the fuel map settings.  Please note that The USA is still a little behind in Using frequency controlled sensors in the MAF Sensor and even the oxygen sensor , as the rest of the world now use… WHY you ask….. well  the USA still has not accepted the metric system as they think they Know Best….. I will leave it to you to come to an opinion on their antiquated choices.

IN the past the MAF sensor is either ignored or the engine ECU is adjusted  be able  to use  a MAFLESS Tune , so as to ignore the MAF sensor readings and their effect on the engine.

IN my case I have found the MAF sensor has been a major sensor for stop start driving , whereas the MAP sensor is the a major sensor for driving at constant Speed

My vehicle economy has been improved from 12.5 L/100 km to 7.2 L/100 km  without using adjustment for the MAF sensor readings. Now with the availability if the New Multimeter from Jacar electronics , the vehicle savings have been further improved which is great fore driving in heavy , stop start  city conditions

Electronic fuel enhancer needs time to activate

The electronic fuel enhancer needs time to activate

Many people fail to get the maximum  benefits out of  their hydrogen fuel system. They may be too eager to have everything operational as soon as they get in their vehicle. Drivers need to understand that the electronic fuel enhancer can’t work properly until the Engine Computer Unit (ECU) has gone through its setup tests.

Each time you start the engine the ECU must read the sensors and set the appropriate fuel map for the engine conditions. This process takes  time.

You should NOT switch on the electronic fuel enhancer modules for the first 3 to 4  minutes of operation. This will give the ECU time to conduct its internal tests and setups.

When driving my V6  Holden Captiva I find it takes under 3 minutes to complete the ECU self tests.  With my 3.6Litre  V6 commodore I wait 4 minutes before switching on the electronic fuel enhancer. This gives the ECU time to read the sensor signals and select the engine fuel map that provides maximum power and best economy.

Without allowing enough time for the ECU  to set up the sensors and initial fuel map,  the fuel savings and power increases are harder to attain.

As long as the engine is running, the ECU will continue to monitor the sensors. Depending upon the sensor reading it continually adjusts the fuel map to provide optimum economy and power.engine cross-section working

PWM power supply explained Contrary to popular belief on places like “ Green Source” the real purpose of a PWM controller is reduce the back emf of the load and provide more usable energy to the electrolysis reaction. All too often these so called experts with little or no traditional scientific training regurgitate half truths and pure ignorance to pretend to know what they are talking about and win the confidence of the scientifically untrained masses A PWM power supply is originally designed as a motor speed control ,which it is well designed for and then put to use as an electrolysis control unit as it is able to fix the current at a given value.

This is ideal to lock in the current drawn , and reduce an excessive load on the vehicle electrical system….. but …. A PWM unit also is designed to reduce back voltage as produced by a n inductive load of a motor and produce a more efficient series of square waves to minimize energy wastage.

However an electrolysis system does not have an inductive load and has no back voltage to overcome and so the extra circuitry of the PWM and square wave production is simply a waste of electronics , a waste of energy and a waste of money

Ideally the best circuit to use In this event is a MOSFET circuit which allows the current to be controlled and locked at a predetermined values and not waste energy or your money on expensive circuitry that dissipates energy as heat to the expense of producing hydrogen

There are many MOSFET power control circuits that Are shown on youtube and google , that are a fraction the price of the expensive commercially available circuits such as the MXA 067, that can be easily built and used to control the HHO systems

In Fact H.F.S has developed a very efficient and simple circuit to control the Systems which we manufacture. Some people will tell you they are trying to make the High frequency PWM produce resonance within the electrolysis cell.

These PWM units oscillate at 100 to 5000 hertz… which is a far cry from the required resonant frequency of several billion hertz. Moral to the story ,,, dont waste your money .

Costly inefficient PWM Power supply running hydrogen Fuel systems

Costly inefficient PWM Power supply,  whilst many experimenters are attempting to manufacture Hydrogen gas for Hydrogen on demand systems used in Vehicles , most if not all are falling into the same hole of wasting excessive electrical energy by using A DC motor speed control unit for a purpose for which it was not  designed.  The DC Motor speed control unit is readily available  and is adjustable in output, but it was not designed for electrolysis units .  They waste a large percentage of the limited input electrical energy as heat energy – energy that is better put to use in converting water into hydrogen gas.

Much is heard about the unit being a pulse width modulated unit and how a high frequency square  wave is produced to reduce back EMF and avoid energy wastage.  Yes Back EMF is a problem in any electrical motor and reducing it does make the motor speed control more effective and efficient, but this is not a motor assembly .  Back EMF is not an issue in electrolysis and so square wave generation is a pointless activity.  It simply means a more expensive control unit, wasted energy in unrequired electronics and a reason to further financially exploit a small community of individuals trying to gain from Hydrogen generation… The Cost of power supply controls has increased exponentially over the past 6years.  Compare the cost of so called HHO control units and the cost of far more complex and superior Solar power PWM control devices…. These superior solar power control PWM units are more substantial, superior units that can be modified for use in HHO systems and are a fraction the cost of the DC motor speed control units.

However even these solar devices are PWM and have specifications that are unneeded   for hydrogen generation systems

So what is the solution?

Well a control system is required that can limit the current flow into a system and fix the load in the engine electrics. However a much simpler switching system that uses MOSFETS , Power transistors , aluminium heat sinks,  Biasing resistors and potentiometers far more efficient , cheaper / simpler system  for powering the hydrogen generator.   We have done away with the square wave generation procedure to make the control unit simpler , less prone to heat damage and thermal runaway and allow more electrical energy be used to produce Chemical energy in the form of Hydrogen.

A major advantage of this new control unit is that it is simple to construct and Use and is inexpensive.  Why pay $150 for a deficient PWM motor speed control unit , from Malaysia when a simple MOSfet circuit costing under $10 can do a better job.

We at Hydrogen fuel systems pty Ltd have investigated a number of such control units and are in the final stages of selecting the Best …. Remember the old ”KISS” principle….. KEEP IT SIMPLE STUPID!
