CONTROL OF EXHAUST EMISSIONS IN CATALYTIC ACTIVATED SI ENGINE WITH INDUCTION OF MAGNETISM N. VENKATESWARA RAO & M. V. S. MURALI KRISHNA Department of Mechanical Engineering, Chaitanya Bharathi Institute of Technology, Hyderabad, Telangana India ABSTRACT 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
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. KEYWORDS: Effect of Pollutants, Copper Coating & Magnetic Induction

1. INTRODUCTION The exhaust emissions of SI engine depend on traffic density, layout of the roads, stop-go service, time of idling, and engine conditions. [1]. Output products from petrol engine create severe health issues like loss of appetite, severe headache, vomiting sensation, dizziness, respiratory decreases, nerve disorder when inhaled in. [1-3]. They also cause environmental problems such as Greenhouse effect and acid rain. Therefore they are to be reduced at any cost. Out of variety of sources available, to improve the workability of the engine and reduce pollution levels of the SI engine, cuprum coating is one of the techniques [4]. Cuprum is a poor insulator of heat and it improves agitation of combustion. Investigations were conducted with SI engine with cuprum coating technique to reduce pollution levels of the engine. Alcohols were used to control pollutants from SI engine as alcohols are renewable in nature. [5-13] Exhaust emissions were studied in a petrol engine. They reported that a decrease in the HC in exhaust. Studies were reported on two-stroke gasoline engine with provision of magnets of variable intensities (2000,4000, 6000 and 9000 Gauss) [14-19]. Specific fuel consumption (SFC) decreased by 1% with the use of magnets. They reported that CMO and PBHC emissions decreased by 30%, and 40%, howevercarbon dioxide levels increased up
