new distance ring - for lifting up the cylinder- for less compression …
luckily found some scrap piece for cutting it out…never throw scrap away!

the way of no return…cutting the thread for spark plug with a washer as guide helping
spark plug sits deep inside…it requires also a modification of the plug

blocking of the starter diesel quantity lever. (left)
right, where the screwdriver shows, is the blocking screw for the diesel pumps rocker arm.
so the rocker arm is not more touched by the cam.

the plug for the spark plug, made longer by a piece of soldered copper pipe.
hope that the insulation piece, made of PE pipe, keeps up there with the heat…otherwise i must make the insulation from the white porcellane shower handle…

from where is the gear of the regulation?
found in the kitchen equipment this noodle machine…the gears are really extreme hardened…the straight part i made from a piece of a flat spring…

Gain a throttle, lose the thin noodles / spaghetti. Give and take.
Brilliant repurposing Giorgio and beautifully made

Giorgio, l too have been almost beaten by the wife for stealing kitchen appliances before 
The PE pipe unfortunaly probably will not last and may make a huge mess in your engine… it gets real soft real fast. The other day l put a spool of the same pipe in the engine bay of an diesel air compressor at work to soften it and made a mess, the engine heat melted it

yes, i think also…a further option would be to cut away the complete injector seat block, than the plug stands relatively free…

excuse this question a little out of context
From what maximum engine speed do you recommend against choosing an engine for conversion to wood gas?
Koen had a small truck converted to coal gas which seemed to run well despite the relatively high RPM!

It depends. Usualy the engines like runing low but the 4cyl 16v l had in my Lacetti realy liked to spin.

would load some fotos of first test run, but computer not finds the sd card…
starting first not works, than with more ignition advance more than 22 degree, it starts immediately, sounds like as diesel before…compression seems right, also the regulation responds, but when a bit longer idling, and than going to more open throttle, the motor stalls…

Hello Giorgio, you have a rather large engine, which can take in a lot of gas when the throttle is fully open. The gasifier cannot adapt to this change so quickly, I can only suggest one trick, which I also use on my tractor, in addition to the throttle valve, which is controlled by the centrifugal regulator, I also have a manual throttle, so for this case, when the engine runs for a long time without load and then suddenly we increase the rpm, the throttle from the centrifugal regulator is currently opened to 100%, and the manual throttle is only opened to 20% and stifles the flow. The engine slowly builds up rpm, the gasifier heats up,… well, after a while I can open the manual throttle to 100%, and the rpm regulator regulates power and rpm with its throttle, an additional manual throttle also comes in handy if detonations start to occur, …

yes, one of my thoughts was also that the gasifier cannot follow so quick in gas production.
next test i will try only by hand on the throttle, slowly opening , without having the regulator between…
can it also be a reason if the ignition advance is too early?
another question to our magneto experts:
the magneto turns with double speed and a lost spark…can the magneto handle this or is danger of overheating, (originally has half rpm as the crankshaft, but this i must not explain…)?

Hi Giorgio, i went back in your post, and saw the drawing of the magneto, it’s a rotating magnet type, it should handle the speed with no trouble, probably good for up to 5000 rpm, or even more.
The older ones with rotating windings could be more sensitive.

I agree with Goran about magneto ignition, the spark is even much better if the magneto rotates faster.
This diesel engine has a well-designed combustion chamber in the piston, which mixes the gas well during compression, which allows for fast combustion, if you hear diesel operation under load, it is perhaps 20° premature ignition. ? The high compression ratio and strong swirling of the gases allow for good and fast combustion, but a strong spark is required to ignite such compressed and swirled gases.

Yes! And American hot-rodders will know why magnetos was popular on old-time race cars, they raised the rpm,s significantly, think: Scintilla vertex on a old Ford flat-head racer, magnetos is still in use sometimes today on drag-race engines, some pushing +20amps at 40000 volts, ignition wires thick as garden hoses.

thanks tone and göran for tips…today we tried again and have had suspect of the spark…there is much sunlight and not good to see, but at least we take the magneto away from the engine and tested with drill engine, and indeed seems the coil has some weakness. before it made a nice strong blue spark, but now weak, maybee the first test run from yesterday was too much for the old coil…fortunately we have another more modern type in plastic shell, and this works really fine, motor runs really nice, strong and gas production followed easy to the required quantity…test drive uphill, all fine , also the regulation works fine…must look for some newer reserve coil, and when time trying görans method to restore the old coil with an extern secundary coil, but for this i must understand before the method…
generally a pleasure to hear and run this modyfied diesel without the typically biting diesel smoke…it got ready just in time, next days we must bring a lot of composted horse manure in the garden…but first , eventually tomorrow seeding the chickpeas…this field we had plowed with the f.i.m. motorcultivator and than roto tillered with the old yellow p.g.s motorcultivator, all on chargas… the gasifier of the pasquali is for those 3 machines.
.i hope soon the foto upload will work again
a trick for finding always the best starting air mixture: once found the right opening of the starter valve near the throttle, we look with a drill what corrisponds to the open ball of the valve, for the pasquali is 6 mm, so , with a 6mm drill i can always find immediately the right valve opening, throttle only a bit open, otherwise requires to much gas, because the glow in the hearth in this moment is only built up with the ventilator and therefore not so big as than with running motor…starts with one draft with the rope…

Giorgio, I never doubted the success of this project for a moment, your calm, thoughtful, precise way of working - success cannot fail. Thank you for sharing your experiences here and for allowing us to learn from you. Converting a diesel engine to spark plug ignition, maintaining speed regulation, adjusting the compression ratio to operate on wood gas,… you have obtained a fairly powerful, high-quality and very economical engine, which you cannot buy on the market, it is suitable for most agricultural tasks and also for heavier transport, these engines can perform 10,000 working hours without problems.
