| Research Abstract |
New fuels which contain chemically modified wood solution were developed and applied to engines and burners. The following results were found through a series of short-term tests. As for a gasoline engine or a pot-type burner in which an evapolation combustion is taken place, some troubles due to the difference of distillation temperature were observed; ingredients of wood sticked to a passage of the fuel and left some amount of carbon deposit in a combustion chamber and knocking occured under the condition of high load in the lower speed range. Carbon deposit was also observed on a heating plate of the burner when an excess fuel was fed. As to a gun-type burner of spray combustion, the new fuels showed sufficient applicability.The new fuels were supplied to a diesel engine as a mixture with diesel oil and a neat fuel. It was found that the output naturally decreased with the wood contents in the new fuels on account of their low calorific values, but the problem was a decline of brake thermal efficiency due to the ignition lag. As the result of the additional experiment, an appropriate injection timming proved to be effective to improve the combustion.
