mini Chopper

[vtajmb]

Thank you, Tang;

Your experience is really interesting: in my case it is the Vangard 2 cylinders in V of 20CV. I know that there are some problems at present on series whose head gaskets quickly blow up; on my tracked motorbike, at the beginning of 1999, a gasket dropped after 15h. Currently, the engine has 1600 hours, and it works.

With a client and friend from Valais (in Switzerland) who uses 10 for caterpillars in the vines there (it is very hot in summer, and it's steep!), We would like to pantonize these engines for two reasons :
- pollution, because these rustic mechanics are far from being optimized in this sense
- the economy, especially for Christmas, my Swiss friend, because in the summer months, he uses more than 8000 Swiss F of SP95

Can I, with your permission, send him your email?

thanks again

Hello,
Ex-oceano I already drove with my chopper in the garden, it works perfectly. The reactor, for sure, it rubs on the ground. If people think that my mill is stew there I no longer understand, because, between running the engine on the spot and accelerating in a vacuum or riding with the bike, the difference is just going first. Except that in the second case it is even more spectacular, if we can say it. For the time being I have not yet rebuilt my reactor, I hesitate to switch to another vehicle, easier to use. I still haven't gotten to spray the water properly with my fuel. I believe that I will address this problem first before undertaking a new assembly ...

Well that's it ... I made a small part that allows me to spray the water very finely but on my 110CC engine it will not work. A good amount of air is needed to spray the water. I think this type of system will work on a diesel engine.

So much the better that your machine has mowed down. It's all stupid, but if you read forums on PMC, on over-generation and other stuff, we see comments like this:

Question: And he drove with it?
Answer: No, but at the fixed point it turned its mill.
Conclusion: in short it does not work, it is not to the point ...

Ok I understand but anyway the saddle of my chopper is 40cm from the ground. So already in normal time to ride it's folklo so with the pantone boujour the damage. I would have liked to mount the engine on my kart but hey it pisses me off to transfer my 2T engine which runs on tons. In this case, the circuit tests will allow me to make the adjustments and the tests that I cannot do with my chopper. Turning with a 4-stroke taco on a kart circuit among the crazy people on the steering wheel could be hot.
Or mount the direct engine on a car. Not easy in terms of assembly but ideal for testing. And no I don't have a tractor ... well I could launch a new fashion in Paris. After the 4X4 that pollute the city. Here is the green tractor on the periph ... not sure to make me that friends ...

Or take a ride with a harrow raised behind your tractor ...

I almost met one right after the top of a mound in the car 22 years ago. 2CV 90 km / h vs tractor + harrow at 30 km / h on a departmental road, it's hot! One has the impression of sinking on a wall bristling with spikes!

If you absolutely want to spray water or a liquid, there is a very simple way two small pipes which join at 90 degrees in the horizontal tube you send the exhaust gases, in the vertical tube which ends with a double tip ( without the ball) it sucks the liquid, the spraying is like a paint spray gun even with fuel oil, it makes a nice mist like cigarette smoke, for it to work well on a single cylinder you need to do a clamping on the exhaust to eliminate jerks at low speed. C, is one of my attempts, winter 2003 to spray engine oil, (for water it's excellent especially if you take the exhaust in its hot part, it takes very little, at low speed it lacks pressure ...
A small note it is relatively easy to modify and experiment on a small stationary engine, but when you are going to fall into a car finished DIY and quick modifications think about it well before doing an assembly on car,

Hello and thank you André
That's why I try to get good spraying first. Because once the reactor installed on the car, it is better that the different assemblies be unscrewable and accessible. If I get a good spraying of the liquid I will reassemble the pantone on my small engine. Just to see if I'm not drowning my reactor yet. However for the road tests it is rather difficult.
I read your post on the Chevrolet . It's great work, it motivated me. I also need to find your post on the venturis. On the pictures we see the venturi you made, then you install a small water carburetor on it. In fact you are inserting a venturi between the reactor and the water carburetor? I had to miss a stage ... You also told me to use the exhaust gases to spray the water, so I'm going to recycle some of it. Is there no problem at this level? I saw that you had made an exchanger to heat the air entering your small fuel on your Chevrolet. These therefore important to have air and hot water at the inlet of the reactor. I think that's also why I don't get good water spray and drowning of the reactor. Finally here I have to get back to it. From what I could understand, you've been on the Pantone for several years. So it's not in a month that I got there. To have experience it takes time.

Hello,
What to remember when using a carburetor for water
the smaller it is the better it sprays (it approaches a paint gun)
it is also necessary that the carburetor spits in an anteroom of a certain dimension, to allow the fog to diffuse, this chamber must be in front of the rod in a hot part but not too much, at the exit of the reactor it is good , the exhaust temperature has dropped considerably.
The water must be heated. it becomes more fluid and the drops finer,
the air can be heated, but not too much in summer it is not necessarily necessary, all that depends on the length of the anteroom and the heating that you give after the carburetor, the excess is as harmful as the lack of heat.
For the venturis I will come back to this, but do not mix the venturi of the carburetor and that in the manifold, although the principle is always the same but their roles are different, that of the carburetor is there to suck up water and that of the collector is there to aspirate what comes out of the reactor.
the venturi gives control over the water flow even over that of the reactor, which is (proportional) to the engine speed in the case of diesel.

Hello
I consulted your method of manufacturing a venturi I think I understood correctly: unsure:. So far I have been mixing pencils. I will try to make one today if I have time. For the anteroom I think it is essential, I had thought about it last night. In my opinion the carburetor and the anteroom, of a larger volume than the reactor, creates a kind of regulator. A bit like that of a fridge or a gas bottle. On household fridges the regulators are simple cappillary tubes, the fact of spitting in the evaporator, whose diameter of the pipes is larger, allows the evaporation of the fluid. Only the length of the capillary changes depending on the fluid used. In addition this anteroom allows the removal of any drop of residual water ...
Good here I made the small venturi the tube diameter is 5mm inside. I made a collar (dudgeon). I grafted a ballpoint pen tip to him the pipe to arrive is from the capillary (Diam 1mm inside). I tried with compressed air to force the air through the venturi. The water diffusion is great . A beautiful fog. It spits well but the speed of the air leaving the air gun is important. I don't know if the spray will be as good with the engine vacuum.
Good this time I think I give up the modifications on the Chopper I go to a great 5 rdv on my new post but nothing prevents to continue this one for information on the Chopper.

Hi everybody
A quick question to expert Pantonizers.
Today I redo the assembly 100% Pantone on my mini chopper.

I installed a Dell'orto 15mm carburetor in which I pass gasoline. It supplies the reactor with 90% petrol and 10% air. The carburetor air filter is blocked at 90% but I have an air inlet valve at the outlet of the reactor to give more air to the engine.
I don't understand why the engine smokes like a 2 stroke.
I reassembled the original fuel in place of origin on the intake pipe. And there more smoke on the exhaust.
I had the impression that the engine was consuming its oil.
What do you say?
How do you explain that ?
