Abstract
The work presented in this paper is an attempt to evaluate the exhaust emission characteristics of a hydrogen-ethanol dual fuel combination with different percents of hydrogen substitutions (i.e. 0-80 % by volume and of 20 % increment ) at three different compression ratios of 7:1, 9:1 and 11:1. Experimental investigations have been carried out on a computer interfaced with; four-stroke cycle, single-cylinder, compression ignition (CI) engine, which was converted to spark ignition (SI) and carburetion, to suit ethanol fuel and a provision was made at the inlet manifold of the said engine to induct hydrogen gas. The effect of hydrogen substitutions on CO, HC, NOx emissions at 7, 9 and 11 compression ratios were determined. It was found that, at 100 % load, the percentage ofhydrogen substitution varied from zero to 80 % and the NOX emissions increased by 58.62, 59.3, 62.74 % for 7, 9, 11 compression ratios respectively. When the effect of compression ratio changed from 7:1 to 11:1 the same change took place in the percentage of substitution which was a reduction of CO and HC by 30.4 and 21.67 %.
