Otherwise building and installing a generator of unknown output on a vehicle with unknown demand is like pissing into the night (and a windy night at that!)
Not trying to be critical, and not in a million years do I mean to deter anyone's experimenting, but we need some hard scientific data...at least to determine some reasonable baseline info.
Clark or should I call you Mr Kent here is a rough calculation i did.
I my 5l V8 I am getting around 15L/100k sitting on 100 KPH that means I am using 15 litres of LPG per hour. Thats 15 Litres of compressed LPG or 4800 Litres in it natural gas form. that works out to 80 Litres per minute.
So at 100KPH I am using 80 Litres of Propane per minute.
now the AFR is 15.4:1 which is stoich for Propane (LPG)
80 x 15.4 = 1232 Litres
so I am actually burning 1232 Litres of GAS per minute.
Yes Propane and Oxygen and air are all gases.
So I suppose when you think about it 2 or even 3 litres per minute of browns soup is hardly even pissing in the wind.
Just one more thing to think about. if your generator is producing 1 litre per minute then it is only producing around 600 mill of hydrogen
thats 0.048% of the total gas needed to move the vehicle.
Evidently it takes 3 or is it 3.5 times as much space to store an equal quantity of hydrogen as it does to store propane and it is suggested you cannot get enough hydrogen into the motor via the manifold to run the car entirely on hydrogen.
They have found the most effective way to use propane is inject the propane into the cylinder while it is still in liquid form and the rapid expansion actually creates the compression to move the cylinders. It actually produces more torque and economy that fuel injected petrol.
seems the only way to use hydrogen on demand to entirely fuel a car is to seperate the water in the cylinder.
