HHO Output

[gmhajh]

I Haven't made a HHO generator yet but was wondering how it works that the HHO is at a constant volume but the engine is at idle or running at high speed. If your volume is great enough for high speed, what happens to the excess HHO when just idling or slower speeds?

The HHO system is hooked up to the vaccum system of the car. This controls the rate at which the hho flows into the engine. The higher the RPM, the more flows into the engine.

HHO is a addative per say...

The additional energy created by HHO in the combustion process is used to offset the energy used from gasoline. Therefore using HHO you require less throttle (and therefore less gasoline through the injectors) to create the same engine power output. The flow through the injectors is directly proportional to the throttle opening %.

Less throttle opening % = Less gasoline injected.

If you are familiar with the Nitrous Oxide systems used to increase engine horsepower, HHO is based upon the same principle.

If you want to test this, use a product such as ether in an aerosol, sprayed directly into the intake of any gasoline engine (at idle) results in an increase in engine RPM without opening the throttle. Too much though and the engine will stall.

Once a HHO system is installed, you can remove the hho tube out of the air intake and watch (and hear) the engine idle drop.

Some have even hooked up a on/off switch in the cabin of the car. Put their car at highway speeds and then turned off the HHO. The car slows down. and you have to give it more gas at the pedal to keep the speed you are at. The difference you see here is the gas you would save.

Thanks Eddie, that helps, but what happens to the excess HHO that is being made when your at idle, compared to the amount you use when at full speed. The HHO unit makes a consistent amount, does it build up pressure? Something must happen with.

If the amount of hydrogen is related to the vacuum, then maximum vacuum at idle willl be highest hydrogen flow. When accelerating from a light, vacuum seriously drops and hydrogen flow will be at its least. Cruising down the highway at a constant speed seems like it would produce the best results, but if someone always has their foot in the gas, it seems like the system would be useless for the most part.

When MANIFOLD vacuum is at it's highest....during idle....VENTURI vaccum is LOW. Conversly, when VENTURI vac is HIGH....during a load....(throttle opened) MANIFOLD vac is LOW. This is why the shape and placement of your input tube is so important. Some guys tee their hho supply tube and run one end of it to manifold vac (after pcv valve) and the other part of the tee to the venturi vac in the air delivery system....now, I agree that noone has been able to explain successfully to me exactly WHAT happens to the hho during prolonged idling for instance or a high manifold vac run down a long hill with closed throttle....Anybody care to try.................?Newguy/rmg

I'm very new to this whole concept and I'm trying to learn a smuch as possible. I plan to buy my plans very soon and buoild a system. I just haven't quite figure ouy which olans to buy yet. But one thing I've never seen anyone or website address. Maybe it doesn't need addressed,I don't know. So here it is. I keep hearing about o2 sensors and what to do about them. But I have never heard anyone mention the sensor for the throttle body. If this something that needs to be addressed??!! Also; if you have used various plans "Run your car on water,Water4gas,Convert your car into a water hybrid,etc.,etc. Rate your plans for us.

Re:Throttle body
Hi there, Glad to hear that you have a intrest in HHO. There is no need to buy plans, there are a couple (good ones) for free. But it is sites like this that help spread the abillaty for you and I to help not only ourselves but mankind. Back to your question about the throttle body. It is an odd device that was concieved between the good old carb and the now full time fuel injection. The system you have is most likley pre 1995 ( OBD 1) (( have no idea what you are driving)). Need more info...

The amount of gas generated depends on the efficiency of the cell and energy put in. The variations in pressure in the inlet trunking upstream of the throttle will be quite small unless the filter is blocked. The engine still consumes a fair bit of air even when idling - try blocking off the complete air intake with your hand and feel the effect. Unless there is a huge amount of gas being generated there shouldn't be any 'excess'.
