I'm experimenting with fuel ratios leaner than 14.7 > 21.5 Using on demand hydrogen [see water4gas-save.com for more info] mixed into air flow.
1993 Buick park ave
3.8 Ltr V6
fuel inj
My objective is to use the new hydrogen enriched fuel to save gas, increase performance and life of motor. The hydrogen gas has a cooling effect on heads allowing for a leaner gas mix as well as better more powerful burn rate. If I lean it too far out it will raise head temps to a destructive level.
I need to know that threshold temperature so I can monitor it using a cylinder head temperature sensor and stay below it under all the road conditions, yet be able to go above the factory recommendations to achieve dramatic fuel savings for the engine.
I will be using synthetic oils, and a fuel enhancing formula additive for more efficient burn, reduced oil thermal breakdown and lubricocity, less unburned gas, and a combination of O2 sensor/map sensor adjusters to fool the ECU into accepting the new ratios.
The results should be vary dramatic, but I don't want to burn up the motor in the initial stages of all this, so... I need to know the thermal ceiling of the head temperatures so I don't exceed them.
Anyone know this answer ?

I don’t know the answer to your question sorry.
But if you’re going to be raising the cylinder head temperatures by leaning this thing out that much what’s going to happen to Nox output.
Heat & load are the main components for the production of oxides of nitrogen, are they not? You may increase your power (load) and fuel mileage but likely not pass an Accelerated Simulation Mode (ASM) emissions test?

Sorry this took so long to get back. I'm utilizing an electrolizer generator. It's principle function is to seperate hydrogen and oxygen molecules in water and using vacuum to send them into the airstream of the injector assembly. They do a number of functions (including cooling the heads)as well as enrich the fuel mixture allowing for a leaner gas mix. The emmissions are reduced by almost 60% because of the hydrogen, it's turned back into water vapors afer the burn. The hydrogen has more than three times the combustive power then gas per litter, and produces 0.0 SMOG emmissions, which is part of the problem with computerized injection systems.
The MAP/O2 sensors don't read what they think should be in the exhaust (unburned fuel) and then deliberately enrich the gas that draggs the gas mileage back to factory settings. What is currantly in place for this type of hybirdization is these control devices for MAP/MAF/O2 that moderate the sensor sig to conform to ECU specs while allowing the system to lean out and get the savings.
What I am proposing to do is take it to the next level by adding head temperature sensing to the mix (excuse the pun) and get the leanest outcome without any damage to heads, cylinders, rings or valves. Through the hydrogen on demand device the emmissions will actually be reduced so far below the standard that a catalytic converter will not even be needed, even though it's there by law.
The result will be more power, less gas, and longer engine life. There are even more advantages like tax breaks and reduced SMOG emmissions, check out my site...www.water4gas-save.com for additional information.
