Abstract
PURPOSE: To provide an arrangement for fuel injection system of an internal combustion engine, which is capable of transmitting pressure necessary for opening a needle valve and pressure necessary for injecting fuel independently by individual pressure transmitting lines, so that fuel injection rate can be controlled freely to a desired level.
CONSTITUTION: When hydraulic oil is supplied from hydraulic oil supply system B to oil sump 11, head 7 of needle valve 5 is forced upward by hydraulic pressure against the force of spring 9 and the needle valve 5 is opened. Here, if fuel oil has been supplied to oil sump 10 from fuel oil supplying system A, fuel oil is ejected from nozzle 4. On the other hand, if supply of hydraulic oil to oil sump 11 is interrupted, needle valve 5 is pushed back by the force of spring 9 and closed. Thus, in accordance with the fuel injection nozzle arranged as above, amount of fuel injected at each time is determined by the time period when the needle valve 5 is kept open and the fuel injection pressure, both of which can be controlled independently from each other.
