Investigation on a diesel engine's performance with integration of magnetic flux on the fuel line

Application of magnetic flux (MF) on the fuel line of diesel engines is a promising technique to enhance the performance of the engine. In this work, MF was applied by placing neodymium magnet pairs (MP) on the fuel line of a diesel engine test setup. Tests were carried out for different loads in the range of 0-8 kg. In the first stage, performance of the test setup was evaluated without MF for fixed load condition; in the second stage, performance evaluation was done by increasing number of MP on the fuel line - that is, the number of magnetic pairs was increased from 1 to 4. The experimental results confirmed that fuel consumption rate decreases with an increase in magnetic pair from 1 to 3; after employing the fourth magnetic pair, an increase in fuel consumption rate was observed. This clearly gives an idea for the presence of critical magnetic field for fuel savings.
