The only difference was, the Shell station in Nisku that I always use, ran out of diesel! And several fuel stations around there had the same problem. Eventually I found the Canadian Tire fuel station had diesel! Canadian Tire has two kinds of diesel: regular and green (higher grade). I picked the regular. The shell station always has one kind of diesel.

I expected to see a lower fuel consumption result but in fact I got the same result as last time. Don’t know if this made the difference.

Anyway, I feel I need to find a way to lean out the fuel injection - I have not received the HydroxyTech’s kit which includes a VMU. The EFIE sold here does not work well with the wideband O2 sensor on Sprinter. Hope the VMU would make it easier to lean out the fuel.

With the new air induction hose replacing the old one, driving from Calgary to Edmonton (Nisku to be more exact which has a Shell station just off the highway #2) for 290 KMs consumed 26.9 liters of diesel. This is 9.3 L/100KM which is the best fuel consumption ever recorded.

This proves that replacing the old air induction hose with a new one does help with the problem of air leaking that was detected on September 23 and 24.

Will report the return trip result when I get back to Calgary tomorrow.

My idea is, that may be used for reducing the diesel injected. (Is only theory, no probed).

I think about that additional ECU before changing this parameter.

This can adjust with potentiometer and cost over 150€

If you were injecting *lots* of hydroxy (or hydrogen), that would be true… since hydroxy ignites at about 580 C if pure.

However, it’s diluted by the air to far -below- the self-sustaining burning level of hydrogen in air (which is 4% at atmospheric pressure).

If you assume 10 liters of hydrogen (which would be 15 liters of HHO) per minute, that’s getting blended with (at least, the turbo dilutes it even further) 2700 liters of air for the Sprinter running at 2000 rpm… so that’s a “fuel/air” ratio of 10/2700= 0.37 % … not three point seven, but *point* 37 percent. Far too little hydrogen to even -think- about igniting, even at the Sprinter’s 18 to 1 (or higher, 35 max) compression ratio.

Empirically, if it’s having an effect upon his mileage, then the hydrogen must still be in the cylinder when the fuel is injected near top-dead-center.
