Effect of magnetic field on performance and emission of single cylinder four stroke diesel engine

Abstract

-To analyse experimental investigates on the Performance and Emission of Single Cylinder Four Stroke Diesel engine under the power of producingan effect of magnetic field. The magnetic field applied along the fuel line immediately before fuel injector. It has been reported that magnetic field helps to improved mixture formation by increasing the atomization process of the spray in the combustion chamber due to increasing the rate of disintegration of the droplets as a result of reduction in the surface tension and viscosity of the fuel [1]. The effect of magnetic field on the engine performance parameters such as specific fuel consumption, break thermal efficiency, exhausts emissions etc. by applying the magnetic field along the fuel line immediately before fuel injector. The strong permanent magnet of strength 2000 gauss is applied to fuel line for magnetic field. At different engine load conditions the experiments are conducted. An exhaust gas analyzer is used to measure the exhaust gas emissions such as CO, CO 2 , HC and NO X . With the application of magnetic field the percentage reduction in fuel consumption is about 8% at higher load, the percentage reduction in HC and NO X is about 30% and 27.7 % respectively. The CO emission gets reduced with the application of magnetic field at higher load. The percentage reduction in CO 2 emissions is reduced about 9.72% at average of all loads with the effect of magnetic field.

Impact of Magnetic Tube on Pollutant Emissions from the Diesel Engine

“…Contrary to this study, the CO 2 increased by 7% (Ugare et al, 2014) and 10% (Faris et al, 2012). Patel et al (2014) noted 30%, 27% and 9.72% reduction in HC, NO x and CO 2 , respectively, with effect of magnetic field.…”

“…Habbo et al (2011) used 1000 and 2000 gauss magnets in a single cylinder four stroke engine and the specific fuel consumption reduced by 12.9 and 21.3% respectively. In their study, (Patel et al, 2014) reported a 2% increase in BTE when applying a 2000 gauss magnet, while Habbo et al (2011) showed 4% and 7.6% for 1000 and 2000 gauss magnetic fields in single cylinder four stroke engines.…”

“…The diesel fuel is made up of hydrocarbons that are clustered due to various attraction forces (Govindasamy and Dhandapani, 2007a;Patel et al, 2014), which do not allow oxygen penetration for oxidation during combustion resulting in incomplete combustion (Jain and Deshmukh, 2012). Additionally, the hydrogen in the hydrocarbons can exist as either para or ortho giving it opposite nucleus spins (Petkar and Khamkar, 2016).…”

“…It is worth noting that while other pollution control devices are placed at post-combustion zones, the devices using magnetic field are applied on the fuel line prior to combustion in most cases. Patel et al (2014) has reported 8%, 27.7%, 30% and 9.72% reduction in fuel consumption, NO x , HC and CO 2 respectively when using a 2000 gauss magnet on a single cylinder four stroke diesel engine. In another study, Ugare et al (2014) used a 5000 gauss magnet and achieved 12%, 22% and 7% reduction in fuel consumption, HC and CO emissions, respectively, but reported 19% and 7% increase in NO x and CO 2 respectively.…”

“…Previously, few studies have evaluated the impact of magnetic field on the diesel engine and diesel fuel as well as gasoline engines in terms of pollutant emissions and energy performance (Govindasamy and Dhandapani, 2007b;El Fatih and Saber, 2010;Faris et al, 2012;Jain and Deshmukh, 2012;Patel et al, 2014;Chaware and Basavaraj, 2015). It is worth noting that while other pollution control devices are placed at post-combustion zones, the devices using magnetic field are applied on the fuel line prior to combustion in most cases.…”
