From the article:
Experimental and developmental studies were conducted for about 12 months on wood gas generators meant for running 5 hp diesel engines used in irrigation water pumping. Based on the critical design inputs obtained during the study, a prototype of the gas generator has been built and tested along with a diesel engine-pump set. The results of various tests on the system indicate that the' lowest amount of diesel required to run the engine on wood gas is about 15% of the normal consumption. On the other hand, for obtaining the same work output, that it is for pumping the same amount of water at a given head, the best replacement of diesel obtained is about 75%. The paper also includes some comments on the cost of such systems.
