Abstract
In recent years, considerable attention is being focused on environmental problems. In the case of gas pollution, exhaust gases from automobiles is an area that needs a solution to keep the environment clean. In order to solve this problem, we have proposed an improvement of combustion efficiency through the control of the dissolved oxygen concentration of gas oil by treatment in a high gradient magnetic field. In this paper, we report the results of a basic study on the control of the dissolved oxygen concentration in a gas oil. Here, the gas oil maintained at different conditions is passed through a low volume percentage of iron particle chains exposed to the magnetic field of 1 T. Determination of the dissolved oxygen concentration of the gas oil exposed to the magnetic field indicated a reduction in the dissolved oxygen concentration.
