PURPOSE:To stabilize the rate of injection of fuel from a pressured injection nozzle, by automatically compensating the pressure of discharge from a pump by an electrical output signal from a pressure detector, provided between the pump and the pressured injection nozzle. CONSTITUTION:A standard voltage VO, corresponding to a rated flow per unit hour, considering the temperature of fuel being fed into a nozzle 2, is determined as a standard input at an adding-up point 6. When a power switch for a fuel pump 1 is turned on, fuel oil is forcedly fed into the nozzle 2, and is injected from the nozzle 2. At this time, a signal from a pressure detector 3, which detects the pressure of fuel oil, and a signal from a temperature detector part 5, which detects the temperature of fuel oil, are fed into a pressure-voltage converter 4, here a pressure signal is converted into a voltage signal, with the temperature of fuel oil being compensated for the flow rate as same as of the temperature in the case of a standard voltage VO, and is fed back into the adding-up point 6 as the main feed back rate. With such an arrangement, the energy of fuel oil per unit hour, injected from a pressured injection nozzle 2, can be constantly maintained. |
