Injecting water into the engine, reforming particles, Nox, CO

[Christophe]

Yes andré but the problem is that the pressure will decrease over time ... and therefore the flow will be uncontrollable!

And by putting an air compressor + tank + regulation pressure + hoses = price of a pump!

[Capt_Maloche]

In fact what it takes is:

- A water pump with a flow rate higher than 20L / h for a pressure of 3 to 10bars
- a pressure regulator that allows a return of the surplus to the tank
- a piezo-type injector that supports water or a fast solenoid valve to regulate the pulse trains for a flow of 0 at maximum flow (according to the cubic capacity)
- A small electronic box that retrieves the injection information on an injector and converts it into a proportional signal adapted to the injector

For the pump, it would be downright a fuel burner pump that should, by cons I think they do not like water.

[Macro]

Fuel burner pump = gear pump not top for water against it can push 20bars and it supports 60 ° C. Count an 200w engine to run it ...

Hi Capt

I found this small pump 12 volts gear at Conrad, I do not have the pressure but usually a gear pump gives a very good pressure.

Capt I had found this small pump 12 volts has gear that accepts water.

Hello

I do not know if it still exists, there was flush toilets working with this principle: the whirlwind.

a part of the reserve is occupied by air that compresses with the pressure of the water entering the reservoir. moreover, if the tank can contain about ten liters of pressurized water, nothing prevents to fill up with water before leaving, especially if it is only to make some tests, at first.

to recover the pressure of the gases to ensure an acceptable pressurization of the water in the tank, a bypass activated during deceleration of the vehicle, taken on the exhaust!


at least there is pressure available and without special equipment.

yes, thank you Alain should you ask Conrad the available pressure of this pump, do you stick to it?

yes, hello, I had thought of that, but compressing with the gases implies a defiling of the water


but it is true that the exhaust pressure must be higher than the admission, it's tempting

Good evening

on certain recent vehicles, there is no or almost no fuel sent to the cylinder during the deceleration phases, proof is the computers on board indicating zero consumption during these decelerations. so the air entering the cylinders comes out almost unchanged, apart from the temperature!

re Goodnight

by browsing the topics in the forum, I found that, maybe it corresponds to what is sought here.

It is certain, there is no injection in deceleration, to convince you, cut the contact (laughs not, I did it )

There is only very little air in, the butterfly is closed, hence the low resistance

which is very good, no pressure, no injection, but at low speed not possible to regulate the amount of water

that's why I do not (yet) retain this solution

Well, if you had explored the site better, you would have found this:
