Abstract: | This study is aimed at investigating effects of varying the compression ratio at optimum injection timing and nozzle opening pressure on the behaviour of a diesel engine, using a non-petroleum fuel, i.e. a blend of 80% biodiesel, and 20% oil obtained from pyrolysis of waste tyres. The engine was subjected to one lower (16.5) and one higher (18.5) compression ratio in addition to the standard compression ratio of 17.5. At the higher compression ratio of 18.5 and full load, shorter ignition delay, maximum cylinder pressure and higher heat release rate were found for the blend, compared to those of the original compression ratio. The increase in the compression ratio from 17.5 to 18.5 for the blend improved the brake thermal efficiency by about 8% compared to that of the original compression ratio at full load. The experimental results indicated that for the blend at a higher compression ratio of 18.5, the brake specific carbon monoxide (BSCO), brake specific hydrocarbon emission (BSHC) and smoke opacity were reduced by about 10.5%, 32%, and 17.4% respectively, than those of the original compression ratio at full load. |
