Doping an internal combustion engine with water vapor

[AXEAU]

Hello Flytox,

In the principle of the bubbler it is interesting to keep a regular gas flow to maintain correct vaporization.
In order not to degrade too much the carburetor settings at idle, we can imagine a small 3-way valve which would direct the vapor entirely back into the exhaust. and would gradually follow the opening of the throttle to give the full flow in the adm.
Of course, this valve must be placed between the reactor and adm. Under the carbu.
If it is difficult to return the vapor to the ech. , it can be left in the open for testing.

Hello

The first thing to do on a water-spiked assembly on a gasoline engine is to make it work at its best, at constant speed on the motorway, once the right steam and fuel ratios have been found, then we can start to think about regulating at different loads and regimes.
but the first thing is to make the one-speed system profitable. Then make measurements of water consumption at lower speeds with these data we see that trying to make the system profitable at 60kmh, we waste our time, the gains are minimal.
It is necessary to prove that the quantity of water vapor to swallow in the engine is proportional to the load, To test at 110 km / h on easy highway, to test for two hours at 50 km / per hour on the road not easy unless you live in the desert.

even at 80 km / h you can get yelled at on the road ... but the development is sacred ....

Hello André,

At 90 km / h your Chevrolet Lumina V6 (200 hp?: Cheesy :) has little load, not sure that in terms of pollution there are results:

Cleanup engine doped steam engine only in charge?

Indeed, virtually all those who have noticed a doping effect found with a motor in charge.

It would be interesting to carry out a rag test at 90 km / h with and without doping with water on your Chevrolet (bring large rags!)

Hello

I did not do any pollution or rag tests, just measured from full to full for thousands of km, I find it difficult and if in addition you have to test layers in the exhaust pipe I would never get away.
Antipolution and efficiency should in principle follow each other, although for the working catalyst modern engines consume a slight excess of fuel .. an engine running has a ratio leaner than 1 / 14,7 but the catalyst does not like it ..

We solve the problem one at a time.

Yes ... if the pressure of the exhaust is not higher than that of the steam outlet, in which case ... you will make us an EGR valve.

Of course, this valve must be placed between the reactor and adm. Under the carbu.
If it is difficult to return the vapor to the ech. , it can be left in the open for testing.

Yes, you can always make the steam spit out under the car with a "big" pipe so as not to interfere with the flow and condensation.

ps: If you have a 4L that does not start in wet weather
rather than considering a breakdown search, if you can wait and put it in the sun for 2 or 3 hours it can start very well afterwards! (I just did.)

You can try candles in good condition and well adjusted ... ditto for au gratin screws or to put a product in a hydrophobic spray in the igniter. or a Senegalese hood on the igniter. it's better when you're in a hurry, that the car starts immediately.

Another process I just tested to add to the list;

Put a fan heater to operate for a good 5 minutes in the engine compartment flow directed towards the ignition parts = instant start!

In addition, in the list, in very cold weather, the car does not start for more than a second, before taking everything apart, changing, batteries, au gratin screws, delco, think of the exhaust blocked by a large ice cube of frozen water !!
I had the case last year (not in Canada) and had to wait for the thaw.
The car does not drive much, just enough time to fill the exhaust pipe with condensation water !!!
A joke for a mechanic for fun !!

This time, the steam supply will be through a "blown" bubbler. The block diagram while waiting for better ideas ... and the time to build it ...



The pipes: air, water, overflow and steam pass through the double wall of the bubbler to exchange heat.

The LDR ensures a relatively constant temperature of about 85 ° over almost the entire interior surface of the bubbler.

The mini centrifugal compressor blows heated air into the bubbler. Its variable power supply will allow you to vary the air flow.

The following parameters are supposed to be constant:
- water level.
- air and water temperatures.
- LDR.
- For the steam ... we will measure, to say the least, big nonsense

For the dimensions, it will be hot between the engine and the body and all the pipes ....

[gildas]

Beautiful scheme! But the vapor will arrive easily compared to the fresh air entering the reactor.

The variable power supply of the mini compressor would perhaps be better managed according to the engine revolutions than by the accelerator cable (?).
