Combustion efficiency can be improved. For this reason, the number of parts of the combustion efficiency improving device can be reduced, the structure is simplified, and downsizing can be achieved.

In addition, a stopper is attached to the conical portion on the downstream side of the flow path of the cylinder, and a receiving plate for engaging the stopper is attached to the inner surface of the fuel supply cylinder to prevent the cylinder from moving in the fuel flow direction.

Since the flow resistance in the fuel supply cylinder is increased by attaching the cylindrical body, the flow resistance is reduced by making both ends of the cylindrical body into a tapered conical shape, and the pressure loss in the system is reduced. A fixing band is provided for the purpose of fixing a plurality of permanent magnets radially attached to the fuel supply cylinder. When the material of the fuel supply cylinder is a non-magnetic material, the fixing band needs to be strongly fixed to a plurality of permanent magnets so as not to cause displacement due to repulsion between the N and S poles.
