Control of Exhaust Emissions in Catalytic Activated SI Engine with Induction of Magnetism

The output products from spark ignition (SI) engine are carbon mono oxide (CMO), partially un-burnt hydro carbons (PBHC) and nitrogen oxide (NOx) emissions. SI engine is useful for individual transport due to lower vibrations of the engine as its size is small. Compression ignition (CI) engine combustion is it time controlled, which is diffusion combustion.SI combustion is speed controlled, which is premixed combustion. However, SI engine faces criticism, that exhaust emissions from SI engine of CMO, PBHC and NOx levels create health related issues once if they are taken in. CMO from SI engine is converted into carbon dioxide which causes Greenhouse effect. NOxlevels reacts with moisture in the atmosphere causing acid rain. Therefore this is to be tackled in at any cost. Tests were conducted to control harmful emissions of spark ignition (SI) consisted of cuprum coated (300 µm) cylinder head. The fuel particles of petrol were streamlined with the induction of magnetism. Cuprum coated engine (CCE) increased flame speed and turbulence as thermal resistance offered by cuprum is very less. CMO, PBHC and NOx emissions were measured by Multi Gas Analyzer at various values of load. The various working conditions were; with the base engine (BE), with CCE, with exposure of induction of magnetism and without influence of induction of magnetism. CCE with the exposure of induction of magnet drastically reduced harmful pollutants in comparison with BE.
