| Abstract | ||
| An experimental study on performance parameters and smoke emission of a diesel engine was carried out at the different hydrogen energy blending. A single cylinder air- cooled direct injection diesel engine was tested at constant engine speed (1500 rpm).Two important load conditions; full load and half load were tested. At these loads, different quantities of hydrogen fuel are inducted into intake air manifold of the engine. In term of energy, the hydrogen energy percentages were varied from 0% (i.e. 100% diesel fuel) to 35%. Up to 20% hydrogen energy fraction, the results showed that the smoke opacity clearly decreases by 33% and 43% for full and half load respectively. Also, the performance parameters have small improvement except the brake specific energy consumption BSEC (kJ/kWhr) was increased. It was inferred that the best hydrogen energy fraction can be blended with intake air manifold is in the range (20%-25%) for both loads. This hydrogen energy provides high performance parameters and very low smoke opacity. | ||
