BINARY FLUID INJECTION DEVICE

摘要

PURPOSE: To hold the ratio of the amount of fuel to the amount of inactive fluid at an appropriate value by setting the actual amount of fuel injected through the addition in advance to the requested amount of fuel injected of the amount of compensating fuel which is equivalent to the amount of inactive fluid such as water supplied in accordance with the operating condition of a diesel engine, time requested amount of fuel injected being suited to the operating condition. CONSTITUTION: An injection nozzle placed in an engine combustion chamber has a fuel reservoir 12 provided above a nozzle hole 11 provided at its end. A water reservoir 13 from which water is introduced into a fuel supply line 17 is formed above the fuel reservoir 12, one end of the water reservoir 13 serving as a junction 13a where the fuel joins with the water. Further, a water supply line 18 through which water passed through the water reservoir 13 and the junction 13a is supplied to the fuel supply line 17 is provided, and a valve element 15 which provides and shuts off communication between the nozzle hole 11 and the fuel reservoir 12 is enclosed in the injection nozzle 10. The operation of a pump is controlled in accordance with the actual amount of fuel injected which is set through the addition in advance to the requested amount of fuel injected of the amount of compensating fuel which is equivalent to the amount of water supplied in accordance with the operating condition.
