Performance comparison of a CI engine using diesel and biodiesel fuels and a magnetic fuel conditioner

An experimental testing on the relative change of a four-stroke, multi-cylinder, direct injection, water-cooled compression ignition engine using both petrodiesel and biodiesel under the influence of a magnetic field was conducted. The engine was tested using pure petrodiesel (as reference fuel), pure biodiesel and their blends. This was done with and without the magnetic effect under fixed full load and variable speed conditions. Results showed that biodiesel is less influenced with the presence of the magnetic flux than diesel. Further, it was shown that engine performance enhancement is better with biodiesel than diesel without the use of a magnetic field.
