PROBLEM TO BE SOLVED: To provide an injector capable of reducing an amount of unreacted substances discharged along with exhaust of an engine. SOLUTION: A nozzle body 12 formed with a fuel passage 15 and a nozzle hole 16, and a needle 18 opening and closing the nozzle hole 16 use a magnetic material (for example, a ferromagnetic ferrite magnet) as matrix materials and they are formed by a far infrared ceramic material with the magnetic material mixed in SiC ceramics having a highly efficient far infrared radiating function. For liquid fuel, a mixture of water and fuel pressurized and heated to a supercritical state, in other words, an emulsion is used. |
