Hi Jan, I haven’t changed the ignition, maybe I’ll try this in the future, the power is reduced, I shift one gear lower, … now there is no throttle on the air intake, only an air filter, here I will add an adjustable throttle, I saw that built it for you. Otherwise, I can’t keep up with everything, but I say to myself, nothing will escape, everything is waiting for me.

How do you mix the gas with the air? I think your tractor ran much better on gas than mine, I did not think I got to the mix no matter what I did.
Have you thought about how to mount the gas unit?

As I mentioned, the gas opens the regulator, at idle the mixture is poor and then enriches with the necessary, but I notice that it could be even richer at full load, so I will add a throttle to the air intake. I will install the gasifier on the left side of the tractor, the front will be the radiator and the right will be the filter, the bracket will be welded on the bottom to the plate you removed to release the clutch.

How are you going to move the throttle to the air?
Have you found a filter that works without getting a lot of shit in the intake?

I’m thinking of making a unit for the tractor or Iller, does it matter if I do it as the sketch on the left or on the right?
I have a cone in my current unit, and it works, but it’s easier to do as on the right side.

The only difference in my opinion is if your gasifier starts runing hot, the right one will not get effected but the left ones cone can warp.

Ok, you’re right, should I weld the plate in the tube for restriction, or make a ring to put it in, could do more for raising and lowering the restriction?

I seldom weld anything in there. If l do its only a tack weld. Chances are you want to change things, or they deteriorate over time so they need replacing

Today I tested the tractor again, I added a choke to the air intake, increased the ignition by a few degrees, … better power, almost comparable only to diesel fuel, I estimate somewhere 20-30% less, works very, very well, the gasifier also produces constant strong gas.

It sounds very good, now you make me curious if my tractor can run as well as yours.

Great results Tone.
Throttle controlling the air into a compression ignition engine is some we are unfamiliar with.
I am putting up an Engineering explanation on my own topic about the differences between hydrogen fueled IC engines versus gasoline fueled IC engine. Please watch in CC, translated carefully. I think he explains the multiple reasons your engine ran on woodgas once warmed up with the diesel accidentally shut off.
You are using no spark ignition, only injection timing advance, yes.

I will not complicate things too much about the gasifier, I will use 3 different metal barrels to make it, and I have a used expansion vessel ready for the upper part. Everything will be assembled in such a way that it will also be quickly disassembled, the hot parts inside are sealed with ash, … this is a sketch, …

Simple is always best! Looks great

You will use an opened top grate basket attached to an upwards rod shaft, yes?
The rod shaft rotatable?
Smart to heat remove from the rod-shaft with the incoming air. Energy transferring with that air

Thank you for the kind words Kristjan.
Steve, here we have said something on this topic Properties of a good wood gasifier - #390 by Tone.
Otherwise, I think it is best to preheat the air with hot gas and radiation from the reduction zone, because this way we preheat the fresh air, do not cool the hot cone, keep the grille at a not too high temperature, which acts as a heat exchanger. If you think of a gas burner with which you heat the sheet metal, if you move it a little further away, the sheet metal will never glow.

Simple? Wonder what it looks like when you do something difficult, think it looks quite difficult.
What do you think about these dimensions for a 2.2 liter tractor engine? I call this quite simple, but it was difficult to bend a 3mm sheet round, without tools other than a tension band.

Why make a cone shape, make a barrel shape with a flat top raised restriction opening with ash protecting the top. Then you will have more charcoal reserve below your restriction zone. The ash will still protect the sides.
