Description

수소연료엔진 차량의 연료충전 경보장치Fuel charge warning device for hydrogen fuel engine vehicle

본 발명은 수소 연료 엔진 차량의 연료 충전 경보장치에 관한 것이다.The present invention relates to a fuel charge warning device for a hydrogen fuel engine vehicle.

수소를 연료를 사용하는 엔진은 수소 공급 체계는 도 4에 도시하는 것과 같이 수소저장탱크(1)에 저장된 수소연료가 연료라인(2)을 통해 엔진(3)에 공급토록 되어 있다. 여기서 부호 4는 수소저장탱크(1)를 활성화시키기 위해 가열수(엔진냉각수)를 공급해주는 가열수 순환라인 이다.In the engine using hydrogen fuel, the hydrogen supply system is such that hydrogen fuel stored in the hydrogen storage tank 1 is supplied to the engine 3 through the fuel line 2 as shown in FIG. Reference numeral 4 is a heating water circulation line for supplying heating water (engine cooling water) to activate the hydrogen storage tank (1).

그런데 수소저장탱크(1)내의 수소연료가 적정치 이하로 감소된 경우에는 이를 충전해주기 위하여 연료라인(2)의 도중에는 연료압을 측정하기 위한 압력센서(5)가 설치되고 이 압력센서(5)에 의해 측정된 연료압이 일정치 이하일 때 전자제어장치(6)는 충전경고등(8)에 전원을 인가토록 제어하여 점등시키게 된다.However, when the hydrogen fuel in the hydrogen storage tank (1) is reduced to below the appropriate value, a pressure sensor (5) for measuring the fuel pressure is installed in the middle of the fuel line (2) to fill this pressure sensor (5) When the measured fuel pressure is lower than or equal to a predetermined value, the electronic controller 6 turns on by controlling the charging warning light 8 to apply power.

그러나 수소저장탱크(1)는 온도에 따라 평형압력이 다르며 더우기 연료잔류량이 적을 경우에는 같은 온도에서 평형압력, 즉 수소공급 압력이 강하되기 때문에 연료압력 측정에만 의존하여서는 연료보충 시기의 정확한 검출이 사실상 곤란하다는 문제점이 지적되고 있다.However, the hydrogen storage tank (1) has a different equilibrium pressure depending on the temperature, and moreover, when the fuel residual amount is small, the equilibrium pressure, that is, the hydrogen supply pressure, drops at the same temperature, so that only the fuel pressure measurement can accurately detect the fuel replenishment timing. The difficulty is pointed out.

이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 수소압력과 수소저장탱크의 온도 유지를 위해 공급되는 가열수의 온도를 측정하여 미리 설정되어 있는 가열수의 온도에 따른 평형압과 비교하여 공급 압력이 일정치 이상 감소한 경우 수소연료의 보충시기를 알려주게 되는 수소연료 엔진 차량의 연료충전경보장치를 제공하는 데 있다.Therefore, the present invention has been proposed in view of the above problems, and its object is to equilibrate according to the temperature of the preset heating water by measuring the temperature of the heating water supplied for maintaining the hydrogen pressure and the temperature of the hydrogen storage tank. The present invention provides a fuel charge alarm system for a hydrogen fueled engine vehicle that will inform the hydrogen fuel replenishment time when the supply pressure decreases by a predetermined value compared with the pressure.
