| - 2 - (No. 7050). The results indicated that the type of engine had a considerable influence on fuel consumption, alcohol fuels, compared with pure petrol, giving better results on the low-speed Büssing engine and the high-speed Mercedes-Benz engine. On the Daimler lorry engine, fuel consumption was lowest when benzole was added to the petrol. With petrol-benzole-alcohol mixtures the effect of alcohol on fuel consumption was favourable on all three engines, the mean consumption in all cases being lower than with pure petrol. By increasing the compression ratio the engine output and thermal efficiency were also improved. E.C. | ||
