Fuel oil passing cylindrical bodies (7, 107, 207, 307) incorporating one or both of far infrared ceramic pieces (5, 105, 205, 305) and ferromagnetic plates (6, 106, 206, 306) are communicatingly connected to a fuel oil supply path (4) that connects a fuel tank (2) to a combustion chamber of an internal combustion engine 3A or a boiler 3B, whereby the combustion efficiency when fuel oil is burnt in the combustion chamber of the engine room (3A) or the boiler (3B) is remarkably improved as compared with a conventional case to thereby improve the fuel efficiency and greatly reduce harmful substances in exhaust gas. <IMAGE> |
