I can buy ($657.00) a 400 watt 5 Liter/minute oxygen concentrating machine....

To inject 5 LPM of pure (95%) oxygen into the FEH/MMH engine air intake. How much would FE improve due to the lower engine RPM (50% lower..??)to produce a given level of HP..??

FE improvement range..??

 

The machine uses electricity for power? I assume you are going to get that from the FEH?

Willard what the $#%#* are you talking about!?!?!?!?!

Contrary to popular belief, Oxygen is not a fuel, and Oxygen does not burn.... at all!

Oxygen only allows a FUEL to burn ( Gas, Coal, paper, plastic, ).

Adding oxygen to your car's intake in any proportion will only allow you to burn MORE FUEL... not less.

Let's say right now your car burns 99% of what fuel you squirt into the cylinders. 1% goes out the tailpipe because the oxygen ran out before the fuel did. Adding more oxygen gets you closer to that theoretical 100% combustion. Not changing the fuel injection rate, at best, you would get a 1% improvement in FE.

However, if you add oxygen in excess, it allows you to add fuel in excess, and you can now drag race and do a quarter mile in 8 seconds vs. 16.
And get 4 MPG.

Your FEH has 2.3 L engine and it breathes 9,200 L/min of air at 2,000 rpm, which means 1,840 L/min of oxygen.
Adding 5 L/min means 0.27 % increasing.

Since the computer monitors intake conditions and exhaust composition, I would guess that any kind of intake addition or boost would just be counteracted by throttle plate closure with no net change in engine performance.

 

I would think it would be similar to nitrous oxide, that doesn't burn either but it's an awful good accelerant. Adding it burns more fuel however, not less.

The point is...

Suppose the FEH ICE turns at 2200 RPM to drive you along at 60 miles per hour.

If it could produce the same HP at 1500 RPM the engine frictional component would be significantly reduced.

Putting a greater % of oxygen into the mixture, rather than just 20% would require the ECU to balance that with fuel to maintain a 14.7:1 ratio.

Wouldn't work with a "cogged" transmission but with the e-CVT....

 

We did our calculation based on the "air" weighing 1 pound/50 liters and gasoline being 3.8L = 6 lbs and a 14.7:1 mixture ratio for cruising.

 

OK let me see if I can splain it. All horsepower is derived from heat in a ICE. The source of heat is gasoline. to get more hp out of the same engine YOU MUST BURN MORE FUEL. Now you could improve the thermal efficiency of the design with changes in the combustion chamber or as in our engines going to a miller cycle or increasing the compression ratio etc. Anything you do to increase the volumetric efficiency of the engine like high flow manifolds, air filters, larger throttle bodies, etc BURNS MORE FUEL. Its not the rpm as much as its the Gallons Per Hour flow of the fuel.
