Abstract

The main objective of the present work was passing of diesel fuel on magnetic field produced by magnetic pole by 121mT, to improve the physical properties of diesel fuel and cetane number (CN), the diesel fuel produced from Khartoum refinery (Sudan). The physical characteristics and cetane number of used sample were tested according to American society for testing and materials (ASTM), physical properties included: Density, and kinematic viscosity. The cetane number of diesel used in this project was recorded (55.6) before passing on magnetic field, in the other hand the intensity of magnetic field was recorded (121mT). The physical properties of sample after the passing process were improved to the limits assigned by ASTM and Khartoum refinery. CN was increased to 60.3.

Highlights

Diesel, recognizing that the liquid petroleum byproducts might be better engine fuels than coal dust, began to experiment with one of them
Results and Discussion density and kinetic viscosity has been decreased, the reason of decreased the density and viscosity is attributed to the conversion some branched or ring compounds to liner hydrocarbon chain because the branched, cyclo and aromatic compounds considered of higher boiling points, densities and viscosities, the decreased the density and viscosity may be attributed to extra oxidation is done and complete combustion at its optimum value is obtained
Some physical properties and Cetane Number (CN) of sample are checked by applying many tests according to American Society for Testing and Materials (ASTM) before and after passing on magnetic field

Summary

Introduction

Diesel, recognizing that the liquid petroleum byproducts might be better engine fuels than coal dust, began to experiment with one of them. This fuel change, coupled with some mechanical design changes, resulted in a successful prototype engine in 1895 (Gruseand Stevens, 1960). Today, both the engine and fuel still bear his name (Lee., et al, 2002). The first commercial diesel engines were large and operated at low speeds (Yamaki., et al, 2001). They were used to power ships, trains, and industrial plants. An effort in the late ’30s to extend the engine’s use to passenger cars was interrupted by World War II (Davis and Brenner., 2001)
