PURPOSE:To decrease incomplete burning time and improve combustion property by a method wherein the rising of a spray pressure is made rapidly at the starting of burning. CONSTITUTION:A control means 12 is operated by a phase angle control or a frequency control, an electromagnetic pump 10 is driven and controlled by utilizing a spray characteristic of the control means 12, thus, the spray pressure is controlled. Where the minimum phase angle is theta1, the maximum phase angle is theta2, when the electromagnetic pump 10 is started at the minimum phase angle theta1, concerning to the spray pressure charactaristic, the electromagnetic pump 10 is driven and controlled under the maximum spouting out pressure condition, the rising of the spray pressure is rapid. At the starting of burning, when the electromagnetic pump 10 is driven and controlled at the minimum phase angle theta1 under the phase angle control condition of the electromagnetic pump 10, or driven and controlled at the maximum frequency f1 under the frequency control condition, the electromagnetic pump 10 is driven and controlled under the maximum spouting out pressure. Thereby, the incomplete combustion time through which a fuel is not sprayed sufficiently can be shortened, the combustion property can be improved. |
