New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is ... Read moreabout the condition
Compatible Makes: Jaguar

You are bidding on a brand new 30 amp 100Hz PWM (Pulse Width Modulator)

This item is new and in its box and is designed for HHO sytems and 12 volt motor control.

Pulse Width Modulators for Our HHO Dry Cell System

The PWM HHO Generator Controller Parts Specifications   FCC & CE APPROVED

) PWM Unit MX66 Two Transistor PWM

2) Black ABS Plastic Enclosure
Size 4.7" x 3.2"x 2.2" with mounting flange

3) Cooling Fan - 60mm x 10mm Ball Bearing Fan

4) Adjustment Knob

All the holes are pre-drilled and unit comes fully assembled with the fan leads soldered to the board.

You will have to unmount the board by removing two screws and the pot retaining nut to make the connections to the PWM

To install just feed the wires through the large holes in the back of the box connect the two power wires to the two outside spade                  

connectors making sure the + wire goes to the + spade on the PWM and connect the HHO generator to the inside two spade connectors.         

Full Installation Instructions come with this HHO pulse width modulator

The pulse width modulator (PWM) has an onboard trim potentiometer to control the amount of RMS voltage and current to your hydrogen booster

Your HHO Generator will run cooler and make more hydrogen which has greater ability to increase fuel mileage.

The PWM pulses at 100 Hz.

This PMW may be used on any 12 volt system only

EFIE   (Electronic Fuel Injection Enhancer)

 Fuel Injection

Fuel injected vehicles use a computer and sensing devices to sense and maintain the correct air/fuel ratio. One of the key sensing devices is the oxygen sensor. Fuel injected vehicles have one or more oxygen sensors installed in the exhaust stream. The computer extrapolates what the air/fuel ratio is based on the amount of oxygen in the exhaust, as reported by the oxygen sensor.
When Hydrogen on demand device is installed, the petroleum based fuel is burned more completely. One of the results of this is that there is more oxygen (and less unburned hydrocarbons) in the exhaust stream. This is a good thing, and is in fact, what we are trying to achieve. However, the computer will perceive this condition as a "too lean" air/fuel mix. In other words, what is now a desirable condition in the exhaust will be interpreted as "not enough gas", and the computer will direct the fuel injectors to increase the amount of gas being pumped into the engine.The result is that the oxygen sensor and computer prevent efficient combustion from occurring

The Solution
The oxygen sensor "tells" the computer what the oxygen content is by providing a voltage on it's signal wire between 0 and 1 volt. 450 millivolts (.45 volts) means that the fuel/air mixture is correct. Higher values means the mix is rich (has too much gas), and lower voltages means the mix is lean. By adding voltage to the sensor's output, we can compensate for the additional oxygen in the exhaust.
The Electronic Fuel Injection Enhancer (EFIE) does exactly this. It adds a floating voltage to the top of whatever the oxygen sensor is putting out. It has an adjustment that allows you to control, to within a few millivolts, the amount of this added voltage. This allows the computer to be unaware of the additional oxygen content of the exhaust, and the electrolyzer can now achieve it's full potential in fuel savings.
Most cars have oxygen sensors both before and after the catalytic converter. The ones downstream from the converter do not need to be treated. Their data is used to determine when the converter has gone bad, but are not used in the air/fuel calculations. EFIEs are only needed for all upstream oxygen sensors

Wideband Quad EFIE

This is the EFIE for V6 and V8 engines that are equipped with wide band oxygen sensors. Note: Vehicles that use wide band sensors only use them upstream of the catalytic converter. The downstream sensors will still be narrow band. Therefore this product has 2 wide band EFIEs and 2 narrow band EFIEs


Wideband Dual EFIE 

This is the EFIE for 4 cylinder engines that are equipped with wide band oxygen sensors, or any vehicle with one wide band and one narrow band sensor. Note: Vehicles that use wide band sensors, only use them upstream of the catalytic converter. The sensors will still be narrow band. Therefore this product has a wide band EFIE and a narrow band EFIE



The HHO generator wiring has one important necessary feature: its ability to automatically turn on and off the HHO gas generator.
Instead of using a toggle switch to operate the HHO system, a relay is installed. What is a relay?  A relay is an electrical switch that controls another circuit. It is also a device that contain an electrical winding motor inside which when powered up, will allow connection of 2 wires or circuits together. This is important in our Hydrogen on demand wiring which needs to be shut off when we stop the engine. If we are using a toggle switch to turn the HHO generator on, there is a chance that we can forget to shut the toggle switch off.  HHO Is EXPLOSIVE The relay is activated when you turn on the ignition and is turned off accordingly. You can fit a toggle switch in between to deactivate the HHO system as a method of override.  ALL NQ HYBRID SYTEMS COME WITH A 30 AMP RELAY



The Bubbler: is a simple flashback device, used to prevent the burning gas from entering the HHO gas generating chamber and creating an explosion.The HHO coming from the cell moves the electrolyte around. The bubbler acts a reservoir to help with heat build                                                 



Now the installation of your unit should be complete. You are now going to Mix the Catalyst (electrolyte) with Distilled Water. KOH is recommended.                               Potassium hydroxide is an inorganic  compound with the formula KOH. Its common name is caustic potash. Potassium Hydroxide is the best electrolyte for a Hydrogen Generator. We wont use any thing else for catalyst in our HHO Dry cells                                                                                       
The strength of your electrolyte mixture is what controls the amps drawn by your dry cell. To keep my unit running at 18 Amps or less and get a least 1 liter per minute of gas or more)
 Start with 100gms of KOH to 900 gms of  distilled water for start up , you may need to add more  to get higher amps but run your unit with a weak solution to condition it first.
Use "Safety First" rules when mixing KOH or other caustic materials. Mix thoroughly in a separate container.
* Once this has been mixed add to the reservoir, you should be able to see the water flowing into the dry cell. Bring the level up to the 3/4 mark on the reservoir and make sure to put the cap back on.
*** Now you
HHO Dry Cell System should be fully functioning and ready for a test drive. Before you take a test drive start the vehicle, you should now see the water in full circulation. Double check for air and water leaks at this time BY getting a spray bottle and a teaspoon of dish soap once mixed spray on all of your hose connectors, bubbler cap and reservoir cap, if there are bubbles you have a leak and this needs to be fixed.

Always read MSDS data sheets when using corrosive / caustic solutions

Disclaimer In no event will nqhybrids be liable for any loss or damage to any vehicle or person including without limitation, indirect or consequential loss or damage, or any loss or damage whatsoever arising from the use of our products. NQ Hybrids recommends a competent person installs there units and the purchaser does does his or hers own research on the use of these exsperimental fuel cells.

What's a max bid?
Your max bid should be the highest amount you're willing to pay for an item.
We keep your max bid amount a secret from the seller and other bidders.
Max bidding example:
If a current bid is £20 and your max bid is £30, we bid £21 for you.
If no one else bids, you win and pay £21.
However, if someone else places a bid for £35, you will be out bid and the new highest bid on the auction will be £31. You will need to increase your max bid to more than £35 to be the highest bidder.
