Super cool, I’d like to see that for real. Thanks Sean

Hi Bronlin, heres the whole story behind the sparkplug.
Last week a customers car was towed to my workplace, he had accidentally filled up his VW diesel with gasoline.
We helped him, emptied the tank, and changed the diesel filter.
Ofcourse i took the opportunity to save the 50 liters of fuel, it works in my kerosene tractor or in my foundry burner.
But… it smelled almost only gasoline, if i try only little, little of it in the Volvo? Maybe it runs ok?
Well, i know better, i’ve tried before and it didn’t work out well then either…
So it started misfire, first only on woodgas, a little gasoline flushed it, and it ran good again.
Next day, after video, drove to work, started misfiring again, on the way home ran on 3 cylinders constantly, next day, to work, worse, ran on 2 cylinders, smelled like a kerosene tractor.
Saved money: 15 liters of free fuel.
Lost money: 4 new sparkplugs.
Wood is the only free fuel

I have only ever seen pictures of it. It is an 8 hour drive from here. I think students from Northern Michigan University help as well which is 2 hours away. It is basically a big winter party for engineering students. lol
They do have a finnish festival which was last week. I am not aware of any swedish festival though.

Goran, I really don’t know why I would destroy the spark plugs if the gasoline is mixed with diesel fuel,…?
At Fergi I now use 99% wood gas and some propane occasionally, well, very rarely diesel fuel. I can say that when I use diesel fuel I have to clean the spark plugs, because a black coating forms on them, which is obviously conductive and the spark plug does not spark. I heat the spark plugs with a gas burner, clean it with a wire brush and blow it with compressed air, and they work like new again.

Hi Tone, it’s exactly what happened sooty deposits on the plugs, shorting.
I know they are not destroyed, it was more a matter of being able to drive home without to much trouble, just swapping the plugs with new ones.
The old ones i saved, cleaned, and layed out for drying, so in can have them as spares in the car for later.
(And i was unsure how old the plugs could be, couldn’t remember if i had replaced them during the 15 years i had the volvo, but it seems i had, they looked pretty good.)

Here is another excuse that got in the woodgas way.
We are just very clumsy.
Broke down last weekend. Fixed it today. The grass is always greener at the other site. Rented this machine lastweekend. Very famous in The Netherlands but probably not abroad. Every streetworker wants one. Good, so do I. If they dont brake I wont either. Ha ha, we almost did. Not impressed. Our strange Timan lifts more and might be more durable. So I am very happy now, appreciate what I have. What a broken cilinder can do

I am looking to get a true sine wave inverter to use with my water turbine and also function as an uninterruptible power supply for my computers. I have heard that the wave forms of other equipment aren’t the best so I wanted to check them out and compare them against the inverter when I get it. Since I don’t have an oscilloscope, I wrote a program for my Arduino to sample the electrical output of my standard genset and a cheap modified sine wave inverter. For comparison, I also sampled my utility power.
First the utility. I expected a good waveform and that’s what I saw. I don’t know it the distortions are real or just an Arduino artifact (probably), but it gives me a baseline to judge the others by.
Then my genset. I expected something “dirtier”, but the shape confused me. I can’t explain why the shape on the bottom side of the sinusoid is different than the top.
Finally the cheap modified sine wave inverter, It is just a 400 watt model meant for car use, but the waveform really surprised me. I expected something that looked like a step pyramid, but this is just wild. No wonder everything buzzes on this. If I had known this is what it output, I wouldn’t have run anything but a lightbulb on it! (I may have to run it again as it might be clipping at the top, but it still is weird).
I hope there are no surprises with the true sine wave inverter, but I’m not holding my breath!

Did you have a load on the generator and inverter when you measured them? A good resistive load (like a real incandescent light bulb, or heater) might clean things up a bit, especially for the inverter. It’s also possible that some of the distortion on your line power is noise from other loads in your house.

Load may affect it. Grounding may as well. It also could be a sample rate issue.
the quality of caps on the inverters can affect it as well,
This threat might interest you.

When I was little, we used to do the same thing with my dad, but now if we do that, the neighbors call and the fire department comes, if not the police
