|Title:||Performance and emissions achievements by magnetic energizer with a single cylinder two stroke catalytic coated spark ignition engine|
Spark ignition engine
|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.|
