I watched a video on YouTube by NightHawkInLight (https://youtu.be/zX6cQ1ian14) where he used carbon rods and and created an arc underwater and captured the gas produced to burn later. He said that the gas was basically a mixture of carbon monoxide and hydrogen. One of the comments was someone asking if you could indeed run an engine on this mixture. I replied to the comment/question by saying:
“This gas is a similar composition to woodgas. Woodgas has been used for a long time to fuel regular spark ignition internal combustion engines. All you would need is an adapter to mix the the gas with air and pipe the mixture into the carb/intake.”
Now I don’t know the exact composition of the gas being produced in the video, but I assumed that with hydrogen and CO, it should be workable in an engine.
Anyway, someone replied to my comment saying:
“You don’t have to premix with air as this is what the carburetor already does. When they do it that way its just because they were too lazy to drill a hole in the venturi of the carb to add the inlet for the wood gas.”
I was going to reply to this person because A) he called people like me lazy (since my gasifier is set up to mix the chargas and air ahead of the carb), and B). I think he is wrong in that I don’t think you can pipe enough woodgas in through a small hole in the venturi to reach a proper mixture with the air. I stopped my reply to come here and ask you all if it’s possible to do what this person says and actually get an engine to run reliably. I’m not sure I have ever seen anyone do that. I always assumed that the woodgas doesn’t have enough energy density to achieve a correct stoichiometric mixture if piped in through a small hole in the venturi. Am I wrong?
