Back in the 1940, an Australian did some trials on wheat gas producer for vehicles. Got good results, by all accounts the whole operation was much cleaner and the calorific value of the wheat was quite high. Does anyone have details on how the control of the wheat flow to the burner was done. I understand one of the options he was experimenting with, was control by the exhaust flow. I have a 1933 Mathis U6F Lorry that was converted some time in the last War to run on Peat. Peat is not easy to obtain where I am. however spoiled wheat ism at a very reasonable price. So keeping the Lorry running on producer gas but changing the fuel to Wheat, would be a good option and keep her a bit different. Any info would be good. Thanks.
