injector for diesel engines according to the present invention, a fuel chamber which communicates with the outside through the nozzle hole inside provided in the body; Elevating the needle is within the body so as to open and close the upper portion of the fuel chamber; And is provided in the tip of the needle, when the upper portion of the fuel chamber when closed and closing the nozzle hole, a needle for closing or opening the nozzle holes when the opening when the upper portion of the fuel chamber with the increase in height of the needle tip; consists including the needle tip has a fuel channel is formed when the upper portion of the fuel chamber, the fuel opening and closing the nozzle hole to be delivered to the fuel chamber ; in the present invention. With the injector of a diesel engine for, because the fuel is not the pressure drop of the fuel flowing into the second fuel chamber to be generated can be more effectively atomizing the fuel, the fuel injection timing, injection amount, it is possible to accurately control the injection pressure , the combustion gas in the cylinder is the advantage of being able to prevent the nozzle holes from clogging phenomenon is not generated, so the developer is not introduced into the fuel chambers.
