Hello, here I can not help communicating to you an error not to commit and this at the level of the NO thermocontact, I think that you hope to use a "clixon" or similar, not to do, reason for the first overshoot of temperature either it is no longer calibrated or destroyed, I advise you to see the tool that I tooled with full satisfaction, you can see this description at Mr. Peter Meaglia alias Pitmix in its R5 mounting, or for other solution envisaged pertaining to electronics muzo31.
Wishing you a better success with your editing than me.

For the thermostat c good I found pil poile what I wanted in my archives (sometimes it is useful to keep bazarr): a fan trigger contact calibrated at 85 ° c, sensor originally fixed on the rocker cover :D

Hello

the coils are difficult to manage it makes water plugs then it pushes steam by saccade with liquid water
a good online heating system preferable. either double sheet like the GV or tube like MMM in the exhaust
(hello MMM glad you're back)


Before mounting with automatic control, leave the manual and operate it, to find out the favorable conditions
a reactor when it does not pass water it is preferable to let pass air, if it is drowned the air dries it quickly, thus just to control water.

At carburetor it requires a good vacuum so that it sprays well and if possible hot water with all the drawbacks, fouling, nozzle, tartar, but it is more efficient for the reactor.

Same injection as I have every 200km I pass the wire in the nozzle, in the long run it becomes demanding.
when you do a test and you are not on a half-way, the cock is partially blocked, it's all to start again

Hello André, thank you for your advice. For your tartar problem! if you add a little vinegar to your water?
The descaling vinegar contains alcohol (can it be beneficial for combustion?), Probably antifreeze and would certainly favor vaporization!

For the solenoid valve! it is possible for me to place it on the fuel water inlet.

Does this scheme seem better to you?

Hello Gary

As André tells you, you may have a problem with the fuel supplied by the coil. The series of steam and hot water plugs will put panic at your constant level in the fuel tank. With the pressure couplings, steam will escape through all the orifices which it will find, venting of the tank, slow motion circuit, choke etc ... I think of a big irregularity in operation. :frown:

I guess a simple copper elbow heated against the exhaust and higher than the carb would be enough. If the diameter is not too small, the vapor bubbles can escape upwards and not towards the carburetor allowing correct operation. :P

Just for information :
Last year I had a 405 petrol which still worked not too bad, consumption of 9 l per 100. I had the opportunity to buy a diesel zx (first diesel for my 8th car in 20 years of license) . She is dragging, so much the better for my points! It consumes 4,5 l per 100. I bought € 1.000, in very good condition, the occasion mainly resided in the fact that I knew very well the mechanic who maintains it from the start who is a friend.
At the financial level, the € 1.000 of purchase pays for itself in 10 months with the mileage I do per year (15.000 km) with the difference in consumption. And again, I had made these calculations at the time of purchase, in August 2007, with the pump prices of the time!
It works less well, finally rather slower than the 405, no doubt! But it pollutes much less (co and co2 released are directly related to the gasoline consumed if I am not mistaken, therefore twice less pollution), it costs much less to maintain, etc ...
So, I have a 405 for sale, for those who are interested : Lol:
Finally, you'd better change your car !!

The T's are machined so as to remove the thread to insert the tube into it.

The rod is pierced at each end as well as the axle supports, one of which is provided with lengthwise play for expansion. (axis diam 6mm)

The 6mm diam axis will be cut when the time comes!
