The present invention relates to an emergency fuel supply device for compressed natural gas which is formed and supplied with fuel of an auxiliary fuel tank when the compressed natural gas of the fuel tank is consumed.
대부분의 자동차는 휘발유 및 경유등의 화석연료를 사용하고 있고, 이 화석연료는 기관내에서 산화하여 인체에 해로운 유해가스 및 미립자가 대기중으로 방출되므로써 심각한 환경문제로 대두되고 있으며, 이를 제거ㅎ기 위한 많은 연구가 성행되고 있으나, 이의 근본적인 문제해결이 급박한 실정이다.Most automobiles use fossil fuels such as gasoline and diesel, and these fossil fuels are oxidized in engines, and harmful gases and particulates that are harmful to humans are released into the atmosphere, causing serious environmental problems. Many studies are being conducted, but its fundamental problem solving is urgent.
한편, 근래에는 상기한 자동차의 연료원으로 환경보존에 이바지할 수 있는 천연가스를 압축하여 사용하는 방법이 약 반세기전에 제안되어 전세계적으로 이의 연구가 활발히 진행되고 있으며, 이의 기술이 성숙화 되어 실용화 되기에 이르렀다.Recently, a method of compressing and using natural gas that can contribute to environmental preservation as a fuel source of automobiles has been proposed about half a century ago, and its research is being actively conducted worldwide, and its technology is matured and put into practical use. Reached.
제1도는 상기한 천연가스를 연료로 하는 차량의 연료장치를 도시한 것으로, 천연가스가 고압으로 압축된 연료탱크(10)와, 이 연료탱크(10)로부터 분기되는 고압가스라인(20)과, 고압의 연료를 소정의 압력으로 감압시키는 레귤레이터(30)와, 이 레귤레이터(30)에 의하여 소정의 압력으로 감압된 연료를 엔진으로 공급하는 저압가스라인(40)과, 이 연료를 엔진(60)의 실린더내부로 분사시켜주는 인젝터(50)등으로 구성되어 있으며, 상기 고압가스라인(20)과 저압가스라인(40)에는 연료의 누출등을 대비하기 위하여 수동으로 개폐가능한 매뉴얼밸브(70,80)가 각각 설치되어있다.1 shows a fuel device of a vehicle using natural gas as a fuel, a fuel tank 10 in which natural gas is compressed to high pressure, a high pressure gas line 20 branched from the fuel tank 10, and A regulator (30) for reducing the high pressure fuel to a predetermined pressure, a low pressure gas line (40) for supplying the fuel reduced in pressure by the regulator (30) to the engine, and the fuel (60) It consists of an injector (50) for injecting into the cylinder of the), the high pressure gas line 20 and the low pressure gas line 40, the manual valve 70, which can be manually opened and closed to prepare for leakage of fuel, etc. 80 each is installed.
이와같이 구성된 종래의 압축천연가스차량은 일반차량의 배기가스에 함유된 일산화 탄소등의 유해물질을 대폭 감소시키는 유용한 역할을 해왔으나, 상기한 압축천연가스차량의 연료공급장치는 항상 20 bar 이상의 연료를 공급해야 하므로, 연료탱크의 가스누출시 불시에 가스압력이 감소되거나, 연료를 전부 소모하여 엔진으로 연료공급이 제대로 이루어지지 않을 경우, 엔진이 갑자기 정지하게 됨과 동시에 과부하를 받게 되어 엔진의 수명이 단축되는 등의 문제점이 있다.Conventional compressed natural gas vehicles configured as described above have played a useful role in significantly reducing harmful substances such as carbon monoxide contained in the exhaust gas of general vehicles, but the fuel supply device of the compressed natural gas vehicles always supplies more than 20 bar of fuel. Since the gas pressure in the fuel tank is suddenly reduced when the fuel tank is leaked, or if the fuel is not supplied properly due to exhaust of the fuel, the engine suddenly stops and becomes overloaded and shortens the engine life. There is a problem such as being.
따라서, 운전자가 가까운 주유소를 찾아 연료탱크의 연료를 주입하기 전에 연료가 소모되면 차량이 정지하게 되므로써, 상기한 정지된 차량을 견인하는 데 있어서 운전자의 시간적 손실 및 경제적 손실이 막대하였다.Therefore, when the fuel is consumed before the driver finds a nearby gas station and injects fuel from the fuel tank, the vehicle is stopped, thereby causing significant loss of time and economic loss of the driver in towing the stopped vehicle.
본 고안은 상기한 제반 문제점을 감안하여 안출된 것으로, 본 고안의 목적은 압축천연가스를 연료로 하는 차량에서 연료탱크의 연료가 소모되므로써 압력이 감소되어 차량이 정지하거나, 고장을 일으키는 것을 방지할 수 있는 수단을 제공하는 데 있는 것이다.The present invention has been devised in view of the above-mentioned problems, and an object of the present invention is to prevent the vehicle from stopping or causing a failure by reducing the pressure of the fuel tank in a fuel fueled vehicle. It is to provide the means to do so.
이와 같은 목적을 달성하기 위하여 본 고안은 천연가스가 압축저장된 연료탱크와 천연가스의 압력을 소정의 압력으로 감압하는 레귤레이터사이에 가설된 고압가스라인의 중간에 보조 고압연료탱크가 장착되도록 탈착구를 형성하고 상기 보조 고압연료탱크와 연료탱크를 개폐하는 개폐밸브로 이루어진 압축천연가스차량의 긴급연료공급장치를 제공하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a desorption port so that an auxiliary high pressure fuel tank is installed in the middle of a high pressure gas line installed between a fuel tank in which natural gas is compressed and stored and a regulator for reducing the pressure of natural gas to a predetermined pressure. It is characterized in that it provides an emergency fuel supply device of the compressed natural gas vehicle formed of an opening and closing valve for opening and closing the auxiliary high-pressure fuel tank and the fuel tank.
이하, 본 고안의 구성 및 작용 효과를 첨부된 도면에 의하여 보다 상세히 설명하기로 한다.Hereinafter, the configuration and effect of the present invention will be described in more detail with reference to the accompanying drawings.
본 고안의 긴급연료공급장치는 제2도 및 제3도에 도시한 바와 같이, 천연가스가 소정의 고압으로 압축된 연료탱크(110)로부터 고압의 가스를 소정의 저압으로 감압시키는 레귤레이터(130)사이에 고압가스라인(120)이 가설되고, 상기 레귤레이터(130)에 의하여 소정의 압력으로 감압된 연료를 인젝터로 분사하여 엔진으로 공급하는 저압가스라인(140)이 가설된 압축천연가스차량의 연료장치에 있어서, 상기 고압가스라인(120)의 중간에 설치되는 소정의 압력을 가진 압축천연가스가 저장된 보조 고압연료탱크(200)가 탈착되도록 대응되게 형성되고 상기 보조 고압연료탱크(200)가 끼워질 경우에만 개방되는 탈착구(210)와, 상기 연료탱크(110)의 압력에 의해 좌,우로 회동되어 상기 보조 고압연료탱크(200)를 개폐시키는 개폐밸브(300)로 이루어진 구조로 되어 있다.Emergency fuel supply device of the present invention, as shown in Figures 2 and 3, the regulator 130 for reducing the high-pressure gas to a predetermined low pressure from the fuel tank 110, the natural gas is compressed to a predetermined high pressure The high pressure gas line 120 is hypothesized, and the fuel of the compressed natural gas vehicle is hypothesized by the low pressure gas line 140 which injects the fuel decompressed to a predetermined pressure by the regulator 130 and supplies it to the engine. In the apparatus, the auxiliary high-pressure fuel tank 200 is stored so that the compressed high-pressure fuel tank 200 having a predetermined pressure installed in the middle of the high-pressure gas line 120 is detached and the auxiliary high-pressure fuel tank 200 is fitted It is made of a structure consisting of an opening and closing valve 300 for opening and closing the outlet high-pressure fuel tank 200 is rotated to the left and right by the pressure of the fuel tank 110, the removable port 210 is opened only when the quality.
더욱 상세히 설명하자면 상기 개폐밸브(300)는 정상적인 연료공급이 이루어질때는 연료탱크(110)의 압력으로 인해 상기 보조 고압연료탱크(200)의 출구를 폐쇄하고, 상기 연료탱크(110)의 연료가 소모되어 압력이 소정압력이하로 감소될 경우에는 장착되는 보조 고압연료탱크(200)의 압력이 연료탱크(110)의 압력을 초과하여 보조 고압연료탱크(200)의 출구를 개방하고 연료탱크(110)의 출구를 폐쇄하도록 상기 고압가스라인(120)의 타측내부에 소정크기로 돌출되는 걸림턱(122)에 지지되는 힌지타입의 구조로 구성함이 바람직하다.In more detail, when the normal fuel supply is made, the shut-off valve 300 closes the outlet of the auxiliary high pressure fuel tank 200 due to the pressure of the fuel tank 110, and the fuel of the fuel tank 110 is consumed. When the pressure is reduced below a predetermined pressure, the pressure of the secondary high pressure fuel tank 200 to be mounted exceeds the pressure of the fuel tank 110 to open the outlet of the secondary high pressure fuel tank 200 and the fuel tank 110. It is preferable that the hinge type structure is supported by the locking projections 122 protruding to a predetermined size inside the other side of the high-pressure gas line 120 so as to close the outlet.
또한, 상기 탈착구(210)는 내부 일측에 소정크기로 형성되는 연료통로부(212)와, 상기 연료통로부(212)를 통로(220)에 대하여 개폐시키는 볼(214)과, 상기 볼(214)을 소정압력의 탄성력으로 지지하는 스프링(216)과, 외측에 소정길이로 형성되는 나사부(218)로 이루어 진다.In addition, the removal port 210 is a fuel passage portion 212 formed in a predetermined size on one side inside, the ball 214 for opening and closing the fuel passage portion 212 with respect to the passage 220, and the ball ( 214 is formed of a spring 216 for supporting the elastic force of a predetermined pressure, and a screw portion 218 formed to a predetermined length on the outside.
상기 볼(214)은 나사부(218)에 보조 고압연료탱크(200)를 장착하여 가스압이 작용하면 후퇴되어 연료통로부(212)와 통로(220)가 연결되도록 한다.The ball 214 is equipped with a secondary high-pressure fuel tank 200 to the threaded portion 218 to retreat when the gas pressure is applied so that the fuel passage 212 and the passage 220 is connected.
이와 같이 구성된 본 고안의 긴급연료공급장치를 정상적인 상태와 비상시의 상태로 구분하여 설명하면 다음과 같다.The emergency fuel supply device of the present invention configured as described above is divided into a normal state and an emergency state as follows.
먼저, 긴급연료공급장치에서 연료의 공급이 정상적인 상태에서는 개폐밸브(300)가 보조 고압연료탱크(200)의 압력을 초과한 연료탱크(110)의 압력에 의하여 보조 고압연료탱크(200)의 출구가 폐쇄되고 연료탱크(110)의 출구가 개방되어 레귤레이터(130)를 통과하여 엔진으로 공급되므로써 정상적인 연료흐름이 이루어진다.First, when the fuel supply is normal in the emergency fuel supply device, the opening and closing valve 300 exits the secondary high pressure fuel tank 200 by the pressure of the fuel tank 110 that exceeds the pressure of the secondary high pressure fuel tank 200. Is closed and the outlet of the fuel tank 110 is opened to pass through the regulator 130 to be supplied to the engine to achieve a normal fuel flow.
한편, 상기 연료탱크(110)의 압축천연가스가 누출되거나, 전부 소모되어 연료탱크(110)내의 압축천연가스압력이 낮아지는 비상시에는 탈착루(210)의 나사부(218)에 대응되게 끼워진 보조 고압연료탱크(200)내의 연료압력이 통로(220)의 배출구측에 설치된 개폐밸브(300)에 주연료의 가스압력보다 크게 작용하여 개폐밸브(300)가 통로(220)와 고압가스라인(120)이 연결되게 작동된다. 이에따라 보조 고압연료탱크(200)의 연료가 고압가스라인(120)으로 유입된다.On the other hand, in case of emergency that the compressed natural gas of the fuel tank 110 leaks or is exhausted and the compressed natural gas pressure in the fuel tank 110 is lowered, the secondary high pressure is fitted to correspond to the screw portion 218 of the removable base 210. The fuel pressure in the fuel tank 200 is greater than the gas pressure of the main fuel to the on-off valve 300 installed on the outlet side of the passage 220 so that the on-off valve 300 is the passage 220 and the high-pressure gas line 120 It works to be connected. Accordingly, the fuel of the auxiliary high pressure fuel tank 200 flows into the high pressure gas line 120.
즉, 보조연료탱크(200)의 출구를 폐쇄하고 있던 개폐밸브(300)가 압력의 고하에 따라 연료탱크(110)측으로 회동되어 상기 고압가스라인(120)의 걸림턱(122)에 걸려 지지되면서 상기 보조 고압연료탱크(200)의 출구를 개방함과 동시에, 상기 연료탱크(110)의 출구를 폐쇄하므로써 보조 고압연료탱크(200)의 연료가 레귤레이터(130)로 통해 감압되어 엔진으로 공급된다.That is, the on-off valve 300 closing the outlet of the auxiliary fuel tank 200 is rotated to the fuel tank 110 in response to the increase in pressure, and is supported by the locking jaw 122 of the high pressure gas line 120. By opening the outlet of the auxiliary high pressure fuel tank 200 and closing the outlet of the fuel tank 110, the fuel of the auxiliary high pressure fuel tank 200 is reduced in pressure through the regulator 130 and supplied to the engine.
그후에 연료주입구(160)를 통하여 부족한 연료탱크(110)의 연료를 보충하면 연료탱크(110)측의 압력이 커짐으로서, 다시 개폐밸브(300)가 정상적인 작동상태일때의 위치로 회동되므로, 연료가 다 소모된 보조연료탱크(200)를 탈착구(210)에서 탈거하므로써 새것으로 교환하여 사용하면 된다.After that, when the fuel of the insufficient fuel tank 110 is replenished through the fuel inlet 160, the pressure on the fuel tank 110 increases, so that the fuel valve is rotated to the position when the on / off valve 300 is in a normal operating state. By removing the spent auxiliary fuel tank 200 from the removal port 210, it is possible to replace it with a new one.
이상 설명한 바와같이, 본 고안은 천연가스가 압축저장된 연료탱크와 천연가스의 압력을 소정의 압력으로 감압하는 레귤레이터사이에 가설된 고압가스라인의 중간에 보조 고압연료탱크가 탈착되는 탈착구가 형성되고 상기 보조 고압연료탱크와 연료탱크를 개폐하는 개폐밸브가 설치되어 상기 연료탱크의 연료가 전부 소모되더라도 보조 고압연료탱크에서 연료가 공급되어 연료의 흐름이 끊기지 않도록 한 것으로, 본 고안에 의하면 연료의 부족으로 인해 엔진이 정지하거나, 엔진의 수명이 단축되는 것을 방지하여 주는 유용한 효과를 갖는다.As described above, the present invention has a desorption port in which the secondary high pressure fuel tank is detached and formed in the middle of the high pressure gas line installed between the fuel tank in which the natural gas is compressed and stored and the regulator for reducing the pressure of the natural gas to a predetermined pressure. The auxiliary high-pressure fuel tank and the on-off valve for opening and closing the fuel tank is installed so that even if all the fuel in the fuel tank is exhausted so that the fuel is supplied from the auxiliary high-pressure fuel tank to stop the flow of fuel, according to the present invention This has a useful effect of preventing the engine from stopping or shortening the life of the engine.
