Description
본 고안은 수소엔진용 연료공급압력 조절장치에 관한 것이다.The present invention relates to a fuel supply pressure regulator for a hydrogen engine.
종래 수소엔진의 경우 고압의 수소(H2)가스를 일정 압력으로 낮추어 연소실에 분사시키고 있다.In the conventional hydrogen engine, the high pressure hydrogen (H 2 ) gas is lowered to a predetermined pressure and injected into a combustion chamber.
그런데 현재 사용하고 있는 도 2에 도시하는 것과 같은 수동레귤레이터(10)의 경우볼트(11) 조정식이어서 수소 연료 유량에 따라 압력 변동이 심하여 일정압력을 유지하기가 곤란하다는 문제점이 지적되고 있다.However, in the case of the manual regulator 10 as shown in FIG. 2, which is currently used, it is pointed out that it is difficult to maintain a constant pressure due to severe fluctuations in pressure depending on the flow rate of hydrogen fuel because the bolt 11 is adjusted.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 연료유량과 무관하게 압력을 일정하게 유지할 수 있도록 한 수소 엔진용 연료 공급압력 조절장치를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a fuel supply pressure regulating device for a hydrogen engine that can maintain a constant pressure irrespective of fuel flow rate.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1은 본 고안에 의한 수소엔진용 연료공급 조절장치를 나타내는 도면으로 도면에 있어서 부호 1은 수소 봄베(2)로부터 연료믹서(3)측으로 공급되는 수소연료의 공급압을 조절해주는 솔레노이드 제어밸브이다.1 is a view showing a fuel supply control device for a hydrogen engine according to the present invention, the reference numeral 1 in the figure is a solenoid control valve for controlling the supply pressure of the hydrogen fuel supplied from the hydrogen cylinder (2) to the fuel mixer (3) side. .
상기 솔레노이드 제어밸브(1)는 공급되는 전기적 펄스량에 따라 그의 개폐정도가 응답되는 특성(duty 응답특성)을 갖는 밸브로서 고압의 연료를 공급량 조절에 의해 사용 압력으로 낮추어 연료 믹서(3)에 공급하게 된다.The solenoid control valve (1) is a valve having a characteristic (duty response characteristics) of the opening and closing of the response according to the amount of the electrical pulse supplied (duty response characteristics) is supplied to the fuel mixer 3 by lowering the high-pressure fuel to the working pressure by adjusting the supply amount Done.
상기 솔레노이드 제어밸브(1)에 의해 낮은 압력으로 조절된 연료를 믹서측으로 공급하는 연료공급라인(4)에는 압력감지센서(5)가 설치되어 있어 검출된 압력을 전기신호로 변환하여 전자제어장치(6)에 출력한다.The pressure supply sensor 5 is installed in the fuel supply line 4 for supplying fuel adjusted to low pressure by the solenoid control valve 1 to the mixer side, and converts the detected pressure into an electrical signal to control the electronic control device ( Output to 6).
상기 전자제어장치(6)는 압력감지센서(5)로부터의 신호 정보에 의해 이를 기준 압력과 비교하여 낮다고 판정되면 상기 솔레노이드 제어밸브(1)를 제어하여 열림량을 증가시키도록 피드백 제어하며, 높다고 판정되면 열림량을 감소시키도록 제어신호를 출력하므로써 수소 연료 봄베(2)측으로부터 공급연료량에 무관하게 항상 일정 압력으로 연료공급압력을 유지하게 된다.The electronic controller 6 controls the solenoid control valve 1 to increase the opening amount by controlling the solenoid control valve 1 when it is determined by the signal information from the pressure sensor 5 to be low compared with the reference pressure. When it is determined, the control signal is output to reduce the opening amount, so that the fuel supply pressure is always maintained at a constant pressure regardless of the supply fuel amount from the hydrogen fuel cylinder 2 side.
이상과 같은 본원 고안에 의한 수소 연료공급압력 조절장치에 의하면 연료압 조절용 밸브로서 수동이 아닌 전기적 응답 특성을 갖는 솔레노이드 제어밸브를 설치하고 믹서측에 공급되는 연료압력을 검출한 후 이로부터 기준 압력과의 차를 구하여 이를 보상토록 피드백 제어하여 솔레노이드 제어밸브의 개폐량을 조절하므로써 공급되는 연료 유량과 무관하게 항상 일정한 공급 압력을 유지하는 것이 가능하여 엔진의 성능을 향상하게 되는 효과가 있다.According to the hydrogen fuel supply pressure adjusting device according to the present invention as described above, a solenoid control valve having a non-manual electric response characteristic as a fuel pressure regulating valve is installed, and the fuel pressure supplied to the mixer side is detected and thereafter, By controlling the opening and closing amount of the solenoid control valve by obtaining feedback difference to compensate for this, it is possible to maintain constant supply pressure at all times regardless of the flow rate of fuel, thereby improving the engine performance.
