Alternative ways to power hho cell without alternator?

Click For Summary

Discussion Overview

The discussion revolves around alternative methods to power a hydrogen-oxygen (HHO) generator in vehicles without relying on the car's alternator. Participants explore various energy sources, such as solar panels and wind turbines, while addressing the implications for fuel efficiency and combustion processes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Patrick expresses interest in finding ways to power an HHO generator without using the alternator to avoid reducing fuel efficiency.
  • Some participants question the feasibility of generating HHO and its impact on engine power, emphasizing the need for specific data on HHO production rates and power requirements.
  • There is skepticism regarding the effectiveness of HHO in improving gas mileage, with one participant suggesting that using engine power to create HHO may not be beneficial.
  • One participant discusses the theoretical aspects of the Otto cycle and how HHO could potentially enhance combustion speed, while expressing doubts about practical applications and safety concerns.
  • Another participant mentions the efficiency of alternators and the energy requirements for electrolysis, suggesting that practical testing is necessary to validate claims about HHO devices.
  • There is a distinction made between using HHO as a combustion enhancer versus claims of running an engine solely on water, with some participants emphasizing that HHO does not add energy to the system.

Areas of Agreement / Disagreement

Participants exhibit a mix of skepticism and curiosity regarding the use of HHO generators. While some acknowledge the potential for HHO to enhance combustion, there is no consensus on its practicality or effectiveness, and several participants express doubts about the claims surrounding HHO technology.

Contextual Notes

Participants highlight the need for empirical data and testing to substantiate claims about HHO's effectiveness and safety. There are unresolved questions regarding the energy balance and efficiency of using HHO in automotive applications.

Hi my name is Patrick I have been trying to find new ways to power a hho generator in my car ,the problem is that yes you can have great mpg increase but you have to limit the amount of gas being produced ,to control the amount of amparge ,so it does not drag on alternator and thus decrease the mpg ,my question is what can I do to eliminate this problem ,I have thought of solar panels ? Or a small wind turbine ontop of car? Please help!

I don't see a physics problem here.
At what rate do you make HHO ?
How much power do you have to put into your water catalyzer to make that much HHO ?
That much power is what percentage of your engine's power at cruising speed?

Until you know those things you don't know whether you have a problem, much less how to approach it.

Welcome to the PF.

Do you have references about improving gas mileage by adding hydrogen? Making it with power from your engine would seem to be a losing proposition...
 
Well, if you power the cell using a separate source of energy, that wouldn't violate conservation of energy. But using a wind turbine or the alternator would.
 
The HHO enthusiasts believe that adding HHO to the air-fuel mix causes combustion to proceed much faster,

making the engine more closely resemble an ideal OTTO cycle with constant volume combustion segment 2-3.
from https://en.wikipedia.org/wiki/Otto_cycle

The processes are described by:

  • Process 0-1 a mass of air is drawn into piston/cylinder arrangement at constant pressure.
  • Process 1-2 is an adiabatic (isentropic) compression of the air as the piston moves from bottom dead centre (BDC) to top dead centre (TDC).
  • Process 2-3 is a constant-volume heat transfer to the working gas from an external source while the piston is at top dead centre. This process is intended to represent the ignition of the fuel-air mixture and the subsequent rapid burning.
  • Process 3-4 is an adiabatic (isentropic) expansion (power stroke).
  • Process 4-1 completes the cycle by a constant-volume process in which heat is rejected from the air while the piston is at bottom dead centre.
  • Process 1-0 the mass of air is released to the atmosphere in a constant pressure process.
Combustion would ideally take place at top dead center
in reality it starts maybe 30 degrees before and continues well after.. Their approach is to add HHO until the engine's knock sensor detects early combustion and retards the spark.

I understand the premise. It's not perpetual motion, just moving a real cycle closer to ideal..
But I remain skeptical as to practicality. Seems to me a mix with enough HHO in it to do any good would backfire terribly. Indeed a friend of mine blew up his intake manifold.

The latter.The combustible HHO added to the fuel-air mix is supposed to speed up flame propagation outward from the sparkplug.
That left edge of the OTTO cycle is curved in a real engine because combustion isn't instantaneous, they're hoping to square it up a bit.
Knock sensor keeps it from wrecking the engine.

The latter.

In that case, why speculate. All the elements are within reach.

  • Alternator efficiencies peak at 60%.
  • The electrolysis of water in standard conditions requires a theoretical minimum of 237 kJ of electrical energy input to dissociate each mole of water, which is the standard Gibbs free energy of formation of water
  • Any shop with a dynamometer can inject H and O from bottles into the fuel-air mixture, and directly measure the Otto Cycle improvements. This http://revolution-green.com/hho-injection-diesels-truth/is to someone who did it. His comment was, " I have never found a HHO device that could run an engine in a closed loop arrangement (Water for Fuel) without an additional fuel source. In every instance they turned out to be scams or would not allow testing ."
 
Interesting link.

1. HHO does work as a fuel combustion enhancer.

2. It will assist in burning any unburnt fuel. It does not introduce extra energy into the equation other than the unburnt fuel and CO

a far cry from the "run your engine on water" claims.

And on that note, this thread is done. :smile:
