Impact of Magnetic Tube on Pollutant Emissions from the Diesel Engine

Abstract

Magnetic field applied to fuel can alter its characteristics in terms of forces that hold the hydrocarbons together. This principle was used to investigate the impact of incorporating a magnetic tube in the fuel intake in a diesel generator on specifically the energy performance and pollutant emissions. A diesel generator was fitted with a magnetic tube in the fuel intake, which had valves to switch from without magnetic tube case to with magnetic tube case. The diesel generator was operated at constant speed of 1800 rpm at idle condition, 25% and 50% loads, respectively. Additionally, two real diesel cars were deployed with magnetic tube and their fuel consumption compared with that of a car without magnetic tube. With application of magnetic tube, the brake specific fuel consumption and fuel consumption were decreased by an average of 3.5% and 15%, respectively, while the brake thermal efficiency was improved by approximately 3.5%. The particulate matter, carbon monoxide, hydrocarbons and carbon dioxide emissions reduced in the range of 21.9-33.3%, 5.4-11.3%, 29.4-64.7% and 2.68-4.18%, respectively. Both the total PAH concentrations and total BaPeq concentrations can be reduced by about 63%, 45% and 51%, respectively for idle condition, 25% and 50% loads, respectively. These results show that application of magnetic tubes in the diesel engine is a promising technology in pollutant reduction and energy saving.

Influence of magnetized waste cooking oil biodiesel on performance and exhaust emissions of a diesel engine

“…There is increase in thermal efficiencies for magnetized biodiesel blends about demagnetized B10 and B20. Increases of thermal efficiencies for magnetized diesel oil, WCO biodiesel blends B10 and B20 about demagnetized fuels are 2, 4, and 11 %, respectively at full load [27,28,34].…”

“…WCO biodiesel blends B10 and B20 specific fuel consumptions are 0.309 and 0.367 kg/kW.hr, respectively at full load. Decreases of specific fuel consumptions for magnetized diesel oil, WCO biodiesel blends B10 and B20 about demagnetized fuels are 2, 4 and 11 %, respectively at full load [27,28,34]. Figure 5 portrayed thermal efficiency variation with engine load for biodiesel blends in the ratio of 10 and 20% with diesel fuel subjected to magnetic field.…”

“…This led to fuel improved atomization, better fuel-air mixing and reduction of carbon monoxide emission under the effect of magnetic field. Fuel magnetism led to reductions in CO emissions for diesel oil and waste cooking oil biodiesel blends B10 and B20 about 3, 3.5and 4%,respectively at full load [26,27,28,34].

“…Reductions in specific fuel consumption and fuel consumption were about 3.5% and 15%, respectively. Improvement in thermal efficiency about 3.5%.Reductions in CO, HC and CO 2 emissions were in the range of 21.9-33.3%, 5.4-11.3%, 29.4-64.7% and 2.68-4.18%, respectively [34]. Magnets applied to fuel reduce fuel consumption, improve emissions and improve engine operation [35,36].…”

A Study on the Effect of Magnetic Field on the Properties and Combustion of Hydrocarbon Fuels

“…A decrease in specific fuel consumption of 3.5% and an increase of brake thermal efficiency by the same magnitude was observed in their experiments. Kurji and Imran [55] conducted tests on a single cylinder four-stroke CI engine with permanent magnets installed before the injection pump. Fuel consumption reduced up to 15.71% owing to reduced surface tension due to magnetisation.…”
