PURPOSE:To aim at sufficiently atomizing fuel, by forming at least either one of a nozzle body having a jet nozzle and a needle valve disposed in the nozzle body, for opening and closing the jet nozzle, from a magnet. CONSTITUTION:When fuel is fed through a fuel supply passage 4, the pressure of fuel acts upon a pressure acting section 5 in a pressure chamber 6, and a needle valve 3 is retracted to open a jet port 2 at the lower end of a nozzle body 1, thereby fuel is injected from the jet port 2. In this arrangement, both needle body 1 and needle valve 3 are made of homopolar magnetic materials. Further, fuel molecules passing through the gap between both members 1, 3 are magnetized in the uniform condition, and therefore, repulsion and binding are effected among the thus magnetized fuel molecules so that the high-polymer molecules are broken by the inter-friction among the molecules to facilitate the atomization of fuel. With this arrangement, the sufficient atomization of fuel may be established, and therefore, the contact area between fuel and air is enlarged to enable the economy of fuel consumption.
