This weeks hydroxy results

Well, the results I posted last week were good, but the computer in the Chevy is fighting back. Damn the oil cartels and car makers, I’m convinced they are in league to empty our pockets. OBD2 computers are designed for their benefit and forced on us sheeple as being good for the environment.
Filled the car to the brim, did 207 miles of mixed city and highway driving and had to add 4.4 gallons to refill.
Same gas station, same pump and filled to pump click off each time. 47mpg from mixed driving, down from the 53mpg average I got across the city last sunday. Still a long way to go to my 100MPG target.
A few basics about the system I have installed:
The cells are fitted into the space in front of the radiator on my 97 Chevy Cavalier 2.2l with the reservoir/recirculation tank/primary gas seperator under the hood in the space between the cooling fan and the battery.
6 cells with 25 sq inches of active surface for cathode and anode each per cell. Electrodes are 4mm apart wired +-+- . The individual cells are wired in series. 2.3 gallon total capacity including a header tank/recirculating electrolyte system. The cells are all contained in a common electrolyte but with about 4 inches space and plastic baffles between adjacent cells to minimise crossover currents. Also the circulating electrolyte helps to reduce heating from stray electric current.
System runs at about 12 amps warm, when cold 1 cell is bypassed to improve gas generation at lower temperatures, and switched in automaticaaly as the system warms up. In 5 cell mode the system pulls approx 15 amps cold but would blow the 20 amp fuse if allowed to heat up.
Electrolyte is sodium hydroxide in distilled water.
Generates approx 1.6 litres/min of hydroxy/browns gas either with 5 cells cold or 6 cells hot.
Anti backfire bubbler, safety blowout cap and low water sensor are fitted to the system. Low water sensor also cuts out the whole system including sensors if I fail to top up. Hydroxy gas is fed directly into the air intake hose close to the throttle body. The 200+ miles of the last test didn’t trip out the low level sensor, about half a pint of distilled water needed to be added to bring the system back to level.
Resistors in parallel on both Intake air temp sensor (2.4k ohm) and coolant temperature sensor (3.3k ohm) .
Voltage regulator on Manifold Air pressure sensor reducing supply voltage from 5.06v to 4.81v
Voltage adder fitted to oxygen sensor wire lifts the mean point by 265mv
All the sensor mods are controlled by relays so that they are only activated when the Hydroxy system is enabled. When the hydroxy generator is switched off all sensors revert to stock settings.
Next step is to either add another generator or add load sensing controls to regulate the amount of gas produced to the demand from the motor. That should enable me to add more offset to the various sensors and improve results.

Good Day People
Sorry to bother you with my stupid Q. I have built a generator with 2 x ss pipes within one another, about 6mm apart and 250mm long and 45mm diameter. i get 1.5l gas per 4 minutes at 20A max. must i alter my design, because i am building another generator. i am going to use 2 on my vehicle. i am driving a ISUZU 3L diesel. 2008 model. This is the forth forum site that i am visiting for help.
kind regards
Deon

Hi Deon,
6 mm spacing is on the large side, and will need fairly high concentration of electrolyte for the current to push through. 2-4 mm is normal. Smaller gap needs less concentration of electrolyte and 2mm is considered the minimum to allow hydrogen bubbles to build up and escape easily.
If you are only using one cell, it receives the full 12 volts available. Only about 2 - 2.5 volts is needed for electrolysis. 2 cells wired in series will halve the voltage but still flow 20 amps for double the production. You will need to use more catalyst in the electrolyte to bring the current back up.
With 4 of your cells running at 20 amps you would be producing 1 litre per minute which is a reasonable amount of hydroxy for a 3 litre diesel.
With 4 cells wired in series the voltage would come down to about 3 volts per cell which will reduce heating, I would guess your current single cell gets way to hot to handle.
For an electrolyte I would recommend either Sodium Hydroxide (NaOH) ( available easily as drain cleaner, but check the label for 100% NaOH ) or Potassium Hydroxide (KOH) which can be obtained from a soap makers. May need to sign a Hazmat Waiver to get hold of it though.
Use either of the above in steam distilled water to minimise foaming and residue. You would be amazed at the amount of crap that comes out of tap water when you subject it to electrolisis.
Any other points you want clarification on, feel free to ask here.

i really like this topic!.. i’ve learned a lot
