I have a questain about small motor gasifiers. Should small motor gasifiers be more imbert design or the WK fire tube set up .and posibley the fire tube better off insulated with 2.5 or smaller motors, before the air is brought in.

Wayne is too humble!! He uses a WK because that is what works!! Small engine or big engine WK is the way to go!!
Just one guys humble opinion!!

Ok wayne k and herb h i was just checking. I had forgot what size 4 cylinder was in the tractor build in the preamium section.And it seems you had plenty of heat at the outlets too sustain a steady clean burn fuel.I Gess i will build from the tractor design on my S10 4 cylinder and just reduce the weight acording too the truck size and and maintain a decent above average turn down ratio.

Hi Kevin, the new fire tube rebuild I put in the 92 Dodge Dakota from the book will run Wayne’s V-10 Dodge truck it is running my 318 cu in. I know it would run a much smaller engine. I can let it idle for long periods of time. I am planning on using it for back up Generation with my 4 kw if I need it for emergency outages.

Worth noting that Mike La Rosa (anyone know his tag?) worked a lot with the 2.2L Chevy engines, including the S-10. I’m not sure how similar they are to a 2.5L… I didn’t actually know they made a 2.5L. 
Also, what year range is your truck/engine?
Hy bob mac i have the wk built from the book in my truck, i think i tilted the cam bearing rebuilding my motor, or i would be DOW ing by know, hopeing i did not spin a cam bearing when i tear it all back apart too fix. Oil psi is 55 till about 10 miles then it starts too drop off 30 and 35 psi so had too stop driveing till fix.my burn tube is built like the tractor and the rest is the same as the reg 318 dakota build version.May i ask what is your new fire tube set up same as the original or tractor recycle.

Look at Wayne’s V-10 rebuild on his fire tube. He put 10 nozzles in his and I put 12 nozzles but my nozzle holes are smaller.

Just a note, this thread is in General Discussion (has to be for Kevin R’s sake). Links to posts in the Premium area are fine, don’t post actual pictures of firetubes etc. Thanks!

Kevin, I posted it on the “general Discussion” thread where anyone could looked at it. I should have just message you instead so other people who have not paid could not see it. You did pay. That is only fair for all of use that have paid for the book and premium.

Check out what Jo Olsson, Don Mannes and Christian Leitinger have achieved with small displacement 4 cylinder engines, all builds diverging from the WK gasifier, but excellent engineering and excellent results.

Built two hay filters for my non wk. ranger gasifier with heated hopper, i ran it with out hay filter, testing the cyclone method, no luck with cyclones too rid the silt. Seems too heat up quik too drive. Though cools down rather fast as there aint any steel in the hearth area with my ceramic blanket burn tube, my wood this year may be dryer than last gasifier test. Heated hopper working good , though i would like too insulate around it too lesson the heat rise efects. Seems too run good so far. Here are my hay filters, about 5 gallon in each canister, I due have a sock type filter behind the back tires allso.Got it bolted too a plated welded too the frame good and solid and will be adding a couple bolts up top too secure allso.Hopefully it will work for few hundred miles before it needs cleaning.
