Gasifier for trucks

4 Reasons for Wood Gas

  1. Abundant Biomass
  2. Wood Is Carbon-Neutral
  3. Biochar to Enrich Your Garden
  4. Energy Independence

Modern trucks with multi-port fuel-injected engines convert better to wood gas.

Wood-Chunker-Feeding-Wood1Wood Chunker

see video here.
It cuts on an ascending bevel so that every revolution of the drum slices off a roughly 2-inch chunk. Keith and his wife, Lisa, lay out the chunks on tarps so they will dry in the sun. After the chunks are dry, Keith stores them in old feed sacks, several of which are easy to keep in a truck bed. The chunker is powered by a thrifty two-cylinder diesel engine. One hour of work can cut and spread up to 2,000 pounds of wood chunks suitable for driving (after drying).

16 pounds of dried wood to take the wood gasification truck as far as 1 gallon of gasoline would (21 miles in conservative driving). So one hour of work with Wayne’s chunker produces the equivalent energy value of 125 gallons of gasoline (a value of $437.50 if gasoline costs $3.50 a gallon) that Wayne can use to travel 2,625 miles.  In Bransby’s 2010 tests, the Dakota achieved 21 mpg on gasoline and 29 “mpg” on wood gas.


Like any typical wood gasification system, Keith’s setup has three basic components: a gasifier, a radiator and a filter.

The wood gasifier consists of upper and lower chambers in the form of drums connected in the middle by a heavy spacer. The upper drum is a lidded hopper where the wood chunks are held. There is an internal air inlet manifold that introduces oxygen a few inches from a restriction, which causes a high temperature (about 2,700 degrees) to be created in a small environment. This is where the gasification takes place.

The hot gases go from the gasifier to a heat exchanger, where the gaseous fuel is cooled with fresh air. The incoming air piped to the gasifier’s inlet never comes in contact with the exiting fuel gases.

Wood-Chunker-Feeding-Wood2Next, the gases go to a radiator, or cooler, which Keith has skillfully camouflaged as a bed rack. There are two inlets and two outlets, so each side of the rack has cooling capacity. Here, the gas temperatures drop below the dew point, and the condensation drains into small tanks.

The third component, the filter, is simply a clamped-lid barrel filled with hay. This removes most of the particulate matter contamination in the wood gas.

After being cooled and filtered, the wood gas is pulled through two branches of PVC piping to the engine compartment. Homemade “slingshot” filters separate any remaining moisture and particulate matter from the incoming gas stream.

The cooled, clean wood gas is directed to fittings Keith has installed in the engine’s air cleaner housing. Two inlets are dedicated to fuel gas and two to fresh air, which is drawn in through separate canister filters. Each of the four inlets includes a butterfly valve that Keith adjusts manually with controls on the dash.

Operation of the vehicle

In preparation to start the Dakota, Keith flipped the switches on a pair of small in-line bilge blowers and opened the gasifier lid to reveal remnants of cold char in the tank, which he ignited with a propane torch.

“With a poker rod I make a little void that goes down to the center of the hearth,” Keith says. “I’ve got those blower switches fixed to where I can either blow or suck the air through to get the wood going.”

After pouring a sack (about 12.5 pounds) of dried wood chunks into the chamber, he sealed the lid and started the truck on gasoline. We drove about a quarter of a mile on gasoline, then he switched over to wood gas with the touch of a lever.

“On this truck, I’ve got a sensor and gauge that monitor the exhaust gas, telling me if it’s too rich, too lean or just right,” Keith says. “I’ve also got vacuum and temperature gauges — sort of like a doctor’s stethoscope and blood pressure monitor — that let me keep an eye on what’s going on. Since wood gas is slow-burning, it helps to advance the timing a bit. The older Ford does that with a cable, but the newer models are smart enough to automatically adjust to the fuel.” Keith says the vehicle performs slightly better on crisp days, when humidity is lower.  Keith sized the Dakota’s wood gasifier to allow 50 to 75 miles on one fill.

Wood-Chunker-Feeding-Wood3Wayne Keith’s Wood Gasification Conversion Tips

  • Choose a truck with ample room under the hood, as well as around the engine and chassis.
  • Electronic fuel-injected engines have streamlined air intakes, which convert better than carbureted engines.
  • Multi-port fuel injection is preferable over throttle-body injection. Generally, trucks built after the mid-1980s use fuel injection.
  • Large-displacement engines have more power and give better results on wood gas.
  • High compression improves performance with wood gas: It burns slowly and has great antiknock qualities. Wood gas supports a compression ratio of up to 16:1.
  • It is possible to convert diesel engines to use wood gas, if given the correct compression ratio. But the injector pump has to furnish the ignition with at least 5 percent diesel.
  • Ignition timing should be advanced because of the slower-burning gas. Modern engines with electronic ignition will automatically advance the timing.
  • It takes about 200 to 300 hours to convert a truck to wood gas. Keith’s record-setting Dodge Dakota took 250 hours of work.
  • The cost of materials to convert is about $500. Many components can be found free.
  • Wood-Chunker-Feeding-Wood4Tools needed: basic mechanic’s tools, a sheet metal nibbler, a metal-cutting reciprocal saw, a power hacksaw, a drill press, a cutting torch, small wire-feed welder, a solid workbench, and a sturdy vise.
  • The gasifier should be built to match the size of the engine and its airflow volume.
  • The size of the wood chunks affects engine performance. Smaller chunks react faster and give better performance, but the fuel is consumed faster.
  • Hardwood has greater energy density, and thus delivers more range per fill, than softwood.
  • Ongoing maintenance: flushing the cooler and draining the condensation traps every 2,000 miles. Ash residue should be removed every 1,200 miles and the filter medium changed once a year.
  • Moisture content of the wood chunks should be less than 25 percent.

Dégivreur et prévention de glace

J’avais besoin d’un dégivreur de pare-brise et j’ai trouvé ces recettes; elles sont beaucoup plus économiques que les produits que vous acheter dans le magasin. Il y a une recette pour un liquide dégivreur et une autre pour un liquide qui évite que la glace colle dure à la vitre.

prévention de glacePrévention de glace

Mélangez 3 parties de vinaigre blanc avec 1 partie d’eau. Vous pouvez ajouter un colorant alimentaire pour bien distinguer le liquide après.

Le liquide est pulvérisé sur les vitres la nuit avant le gel – il fera en sorte que le glace ne se forme pas ou qu’elle ne colle pas sur la vitre. Les essuie-glaces vont facilement balayer la glace le lendemain.







windshield ice preventDégivreur

Mélangez 1 partie d’eau avec 2 parties d’alcool isopropylique 70%; ajoutez quelques gouttes de savon à lave-vaisselle. Remplissez le réservoir de lave-glaces de votre voiture avec ce liquide. Il lavera bien les vitres et gardera les tuyaux libres de glace.










Building the walls: The REMOTE System
The wall construction follows the principles of the ‘REMOTE’ wall – Residential Exterior Membrane Outside-insulation Technique – a high-performance building envelope developed by the Cold Climate Housing Research Centre in Alaska. Walls are framed conventionally with 2×6s and sheathing; stud cavities are still insulated with batts, but most of the insulation is on the outside of the sheathing.

This type of design allows vapour and air barriers to be sandwiched in between layers of insulation to protect their continuity. And in the case of polyethylene vapour barriers in such a variable climate as we have in Canada, they perform better on an annual basis when they are about 1/3 into the wall assembly instead of right behind drywall. With the Edelweiss House we have opted to omit the 6 mil poly entirely, its role being filled instead by an exterior moisture-permeable airtight weather barrier (Delta Vent SA) and an interior vapour retarder primer from Benjamin Moore. Vapour retarder primers stop twice the moisture required by building code, but allow walls to dry a bit to the interior during summer months, which is a growing concern among building scientists in terms of summer condensation damage as most homes now are air conditioned.

Siding installation
Whatever your wall assembly is, in order for it to last it has to be able to dry. The Edelweiss House exterior is finished with FSC-certified pre-stained wood siding from Riopel. Siding should protect your interior layers from wind, precipitation and humidity, and it must be able to dry. In order to do so, air and water must be able to move freely behind it so any water that penetrates can drain out, and humidity can escape.

Our weather barrier is covered by 3/4” vertical furring strips, giving ample room for drying. From the bottom, air flows up behind siding and into the soffit, joining air venting through the roof.

Building the roof
We opted for a green roof on this house, for a couple of reasons. Curb appeal would be one, we liked the idea of walking up to an open area of flowers and clover more so than a large sheet of metal, which was the other option. Green roofs can be quite a bit more work but have enormous benefits, mostly in urban areas.

Here in the woods there is no great need for it, but in dense urban centers a green roof offers habitat for birds and insects, and in commercial applications on office buildings they can give people access to green space that isn’t always easy to find in a downtown core.  They can be beneficial for heating and cooling, and though the cost is higher than other roofing systems, the life span is much longer.  The most destructive force on roofing materials is actually not precipitation, but UV rays. Once you cover membranes and they are no longer exposed, it is hard to really put a life span on it, because as evidenced by landfills, plastic underground just does not breakdown at a pace that we need worry about.
