I actually worked in the VictoryGasWorks Developement shop for a couple of years. More than any one thing I was Steve the Engine Guy.
To fuel a diesel on woodgas the compression ratio has to be below 17/1 to prevent loaded pre-ignition in the cylinder gas explosion events. Well right there that eliminates 90% of modern diesels and only a percent of the old lower compression diesels are possible. Then they cannot have rotary injector pumps; even many inline injector pumps proven to need added on modification to the fuel bypassing at the least to cut down on the low diesel fuel flow now well dicumented overheating and accelerated wear issues. The individual unit types injectors systems seem to be the easiest to control and accommodate. So even more diesel engine types eliminated. And you really do not want to run normal spark engine allowable filtered woodgas through a close fitting GM/Eaton rotary lobe blower for long. So out with all of the GM 2-stoke blower pressurized diesels out there. Or onto to unnecessary 3rd and 4th stage expensive elaberate woodgas filteration.
Now that seems to be constant load thing is true - changing loads has severe engine overspeed problems on load shed offs especially by going rich on woodgas and exhaust back firing. So more mechanical or electronic controls needed added to be able to quickly slam the woodfuel on and off or add exhaust air to dillute and cool. Documented.
Then on the turbo’s. Most do not like at all to have suction on the inlet side. Pulls cooling/lubricating oil past the turbo shaft seals - the diesel will love running on this heavy oil “fuel” - back to an engine over speed problem. Documented. So IF you are going to engine suction draw safe the gasifier system as 99% do then you have to change out the turbo for one able to handle suction. OR you can have the whole gasifier system either pressure blown or external of the engine sucked with the woodgas then mildly pressure delivered to the engine like is done with LPG and NG gasious fuel supplemetaion system. Forst off will take a few kW/me or kW/electrical to power this now constant operating high flow capable gasifier blower system. And then the varying fuelgas needs NOT THEN being matched directly by the engine itself, but now having to be calculated and matched metered will need a whole 'nother system developed, built and added on to control the acutal delivered woodgas flow.
Ha! Ha! Made my biggest woodgas “KaBooms!!!” every were working on pressure delivering!
And I haven’t even covered the combustion/ignition/timing issue differences beteeen the different IDI and DI diesel systems out there.
Anyhow it gets alot more complicated quickly to be acual daily load varing useable than just stuffing a woodgas hose down the air inlet on a diesel engine
Bottom line is the actual experienced diesel engine companies with paid development engineers fueling with woodgas like Wakashaw, IHC, Caterpillar, Cummins/India, Pratash, Mitsubishi and GE-Jenbacher all just spark converted, lowered the CR’s into the 13/1 to 15/1 range on their diesel block based engines for woodgas to get around all of this extra needed development and expense and added multiple systems maintance.
Yeah I watched your Trillion Gasifiers video.
Lots of ooh-rahh videos out there. Cameras are cheap and Internet vidoe requires no other proof or “the rest of the story” results like peer publishing. I’d want to see anything after a minimum of 500 hours variable load run time. Then 5000 hours of across seasons annual results like all of the mainline engine companies will supply on thier spark converted woodgas fueled setups.
Just can’t seem to get this particular Internet myth killed no matter how many actual done-it, tried-it documented written references I’ve put up. Sigh.
If it ever sounds too good to be True - then it ain’t - True that is.
