| Abstract: | This paper presents work conducted on a zirconia (catalyst) activated two-stroke spark ignited engine to investigate the
effect of high gauss magnetic energy on cyclic variation of combustion parameters. A 9000 gauss magnet, made up of
Neodymium-Iron-Boron, is fixed on fuel line before carburetor. The coating is carried out by thermal evaporation technique
on the inside surface of combustion chamber walls and piston crown. In-cylinder pressures were recorded for 500 continuous
cycles using a piezo electric pressure pickup and PC based data acquisition system. Magnetic flux activates preflame reaction
and shortens combustion duration. Cyclic variation of combustion parameters due to magnetic energy were 25.1% less than
the base engine and mean value of the peak pressures were found to have upper shift of 13.6%. Magnetically energized
zirconia coated engine performed better than the base engine during running. |
