Influence of Magneto-combustion on regulated emissions of an automotive engine under variable speed operation

The present study investigates the influence of magneto-combustion on the macro pollutants emitted from a multi point fuel injection (MPFI) automotive engine. The regulated emissions of an auto engine include carbon monoxide, un-burnt hydrocarbon (UBHC)and oxides of nitrogen (NOx) which are the by-products of internal combustion of the hydrocarbon fuel used. Depending upon the physiochemical characteristics of pollutants and their concentrations, these pollutants result in numerous physical ailments and mortality. Magneto-combustion is an under investigated technology which effectively reduces the emission of toxic vehicular exhaust. The exposure to an external magnetic field realigns the hydrocarbon structure and alters its combustion properties. The tests conducted on a Maruthi Zen MPFI engine under two different patterns of magnetisation resulted in a maximum reduction of carbon monoxide by 23.97%, UBHC by 13.1% and NOx by 5.23%, thereby reduced the cumulative negative impact on the environment. © 2020.
