What about timing

[alecracing]

It is said that the hydrogen increase the speed of the gasoline burning. Does this mean the flame front will reach the piston before it hits top dead center?? Will the computer automatically reset the timing using the knock sensors? What if there are no knock sensors?

Hi Alecracing

ANOTHER GREAT QUESTION ! I sure hope someone can answer this one as I have querried "hho guru's" on this one too....also without a suitable answer. But then I'm pretty dense,so it may take some time for the REAL answer to sink in.......................Newguy/rmg

hello,

I also want to include my Question with regards to HHO in relation to ECU's response, would it be helpful if i totally disconnect the O2 sensor? so as not to interfere with my hho fuel saving device?

Another thing, if the the ECU will be displaying an error signal if it can't find the O2 sensor voltage, could it be possible to supply the wire from O2 sensor going to Ecu with a constant voltage reading equivalent to rich mixture?
If that is possible the ECU will not make a move to add fuel to my air fuel mixture, because in reality the mixture is just right through the help of the HHO device.

Kindly give me an answer to these.

Thanks and have a nice day.

regards,
elly policarpio

Timing only comes into play when one starts to push to hard. The whole purpose of this exersise is to get the most of what we have in the most efficient way. It is very easy to get off track ( I find myself doing this quite often) and have stop and refocus. The o2 Sensors use milivolts ( less than 1 volt) the working voltage for the O2 sensor to maintain proper ( the magic) air/fuel ratio 14.7:1) is 4.5 -4.7 mv. More voltage will (back feed) may or will damage the ECM/VCU and the vehicle will not run or it will go into a limp mode, either way major monies. Be carefull and yes ask before you do if in question. Take care

I ask about timing because the theory is that it makes the flame front travel faster towards the piston. Whether it is idling or full throttle, the engines PCM is calibrated for a certain fuel. When adding something to make the flame front move faster, how is the computer going to know, unless there is a knock sensor on the engine.

[oneton]

Yes, the flame speed increase. We did some studies before the lower the injection rate the flame front stays closer to gasoline even 15% BTDC is ok,, but when the qunatum increase , we need to go into ATDC.
Current ECU have knock sensor to sense the knock and delay the firing point. If you do not have it, at 2 litre per min, on a small car, better to settle it for ATDC. As we do not have exact timing develop, we let the ECU takes care of it . Well it is worth someone taking a test on it. We have H2 engine and they operate at 5% ATDC.

it has been my experiance that the knock sensors do adjust timing, but to maximize mpg you need several componets, like an EFFIE, which if set right does work well, and a good 30 amp PWM to adjust hho flow and keep the heat generated by the cell down, you do this with a generator that matches the engine displacement of your car, and you will see gains, need help just ask im glad to help

it shouldnt be a problem I have a generator on my 2001 f150 and there is no bad effects it only improves and enhances the performance.
