Experiments were conducted to study the performance, emission and combustion characteristics of a DI diesel engine using sea lemon oil-based fuels. In the present work, sea lemon oil and sea lemon oil methyl ester are tested as diesel fuels in diesel engine in neat form. The reduction in NOx emission and an increase in smoke, hydrocarbon and CO emissions were observed for Neat sea lemon oil compared to those of standard diesel. From the combustion analysis it was found that ignition delay was slightly more for both the fuels tested compared to that of standard diesel. The combustion characteristics of sea lemon oil and its methyl ester closely followed those of standard diesel.Keywords

This study reports a simple micropropagation protocol and thereby rapid multiplication of the useful medicinal plant- Scoparia dulcis L. Single node explants were inoculated on basal MS medium containing 3% (w/v) sucrose, supplemented with different concentrations and combinations of 6-benzylaminopurine (BAP), kinetin (KN), indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) and Naphthalene acetic acid (NAA) for direct plant regeneration. Maximum numbers of shoot (~22) were observed on the medium containing 0.5 mg/l BAP and 0.25 mg/l IAA after four weeks of culture. Regenerated shoots were separated and ischolar_mained on half strength MS medium supplemented with 0.5 mg/l of IBA alone for three weeks. Simultaneous regeneration of shoots and ischolar_mains and in vitro flowering were achieved from the nodal explants on MS medium supplemented with 0.5 mg/l KN and 2.0 mg/l IAA. Well-developed complete plantlets were transferred on to specially made plastic cup containing soil rite. Acclimatized plantlets were successfully grown in garden soil.Keywords

An experimental investigation was carried out in diesel engine operated in both homogeneous charge compression ignition (HCCI) and conventional modes. The engine used in this investigation is single cylinder, 4 stroke, water cooled, constant speed, variable compression ratio diesel engine with a displacement of 553 cc. In conventional diesel mode, the fuel was injected 270 bTDC with a nozzle included angle 1400 and the compression ratio 16.5. In HCCI mode, the fuel was injected 800 bTDC during compression stroke by using modified camshaft, with a nozzle 600 included angle. In HCCI mode, to control the phasing and rate of combustion, the effective compression ratio was reduced to 14.5. From the experimental results it is inferred that, HCCI mode of operation results in reduced smoke and NOx emissions significantly with a little increase of HC and CO emissions.Keywords
