본 고안은 디젤 엔진의 연료 공급 펌프와 분사노즐 사이의 연료 공급관에 전열선이 들어있는 가열기를 권설하여 연료를 가열 공급케 한 디젤 엔진의 연료 가열 공급장치에 관한 것으로 종래에는 디젤엔진에 공급되는 경유를 가열 공급하지 않아 분사노즐로 분사시킬 때에 분사 상태가 양호하지 못하고 폭발 상태가 불완전한 결점이 있었다.The present invention relates to a fuel heating supply device of a diesel engine that heats fuel by recommending a heater having a heating wire in a fuel supply pipe between a fuel supply pump and an injection nozzle of a diesel engine. When spraying with the spray nozzle because of no heat supply, the spraying state was not good and the explosion state was incomplete.
본 고안은 이와같은 결점을 적게하고 완전 연소를 가하여 매연을 최대한으로 줄일수 있게 한 것으로 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to reduce the soot and to reduce the smoke to the maximum by applying a complete combustion as described in detail by the accompanying drawings as follows.
디젤 엔진 동체(1)에 삽설되는 각 노즐(2)과 연료 공급펌프(3)를 연료 공급관 (4)으로 각각 연관시킨 통상의 것에 있어서 연료 공급관(4)의 일정 위치에 확개부(4a)를 형성하여 이를 다수 밀집시켜 단일체가 되게 비철금속인 절연체(5)로 몰딩하고 전열체(5)주위에 반원 요구(6)를 형성하여 전열선(7)을 권설한 다음 단일 커버(8)로 피복하고 각 노즐(2)과 전열체(5)사이의 연료 공급관(4)은 열전달관(9)으로 피복하여서된 것이다.In the ordinary in which each nozzle 2 and the fuel supply pump 3 inserted into the diesel engine body 1 are respectively connected to the fuel supply pipe 4, the extension portion 4a is placed at a predetermined position of the fuel supply pipe 4. Forming a large number of them and molding them into an insulator (5), which is a non-ferrous metal, into a single body, forming a semicircle request (6) around the heating element (5), winding the heating wire (7), and then covering it with a single cover (8). The fuel supply pipe 4 between the nozzle 2 and the heat transfer body 5 is covered with the heat transfer pipe 9.
미설명부호 7a는 전선, 10은 자동 온도 조절기, 11은 잔유 연료 회수관이다.Reference numeral 7a denotes a wire, 10 a thermostat, and 11 a residual fuel recovery line.
디젤엔진 동체(1)에 상설되는 각 노즐(2)고 연료 공급펌프(3)를 연관시키는 연료 공급관(4)의 일정 위치에 확개부(4a)를 형성하여 비철금속인 전열체(5)로 연료 공급관의 수개를 단일체가 되게 몰딩하고 외주에 권설된 전열선(7)에 전원을 공급하게 되면 전열체(5)가 가열되어 연료 공급관(4)이 확개부(4a)를 가열하는 한편 연료 공급관(4)을 피복하고 있는 열전달관(9)에 열을 전달하게 되므로 디젤엔진의 연료 공급펌프(3)에 의하여 연료 공급관(4)을 통과하는 연료를 일정온도로 가열하게 되어 디젤 엔진동체(1)에 삽설된 각 노즐(2)에 의하여 엔진 내로 분사되므로 분사되는 연료의 온도는 연소에 적합한 온도로 가열되기 때문에 무하 상태가 양호하고, 무화된 연료가 항상 일정 온도로 가열되어 폭발시 완전연소를 기할수 있으므로 디젤엔진으로부터 배기되는 배기가스에 매연과 유독가스를 줄일 수 있고, 완전 연소에 의하여 엔진의 힘을 더 얻을 수 있으며 전열체(5)외주에 권설된 전열선(7)에 자동 온도 조절기를 부착하였기 때문에 분사노즐(2)에 공급되는 연료의 온도가 일정 온도 이상이 되면 자동으로 전원이 차단되고 일정온도 이하로 연료의 온도가 낮아지면 전원이 공급되므로 항상 일정 온도가 가열된 연료를 공급시켜 주므로서 완전연소를 기할 수 있는 동시에 매연을 최대로 줄일 수 있는 이점이 있으며 또한 연료공급 펌프(3)에서는 고압을 유지해야 함으로 밀도가 높은 냉각된 상태이나 분사노즐로 연결된 연료 공급관(4)의 확개부(4a)를 전열체(5)에 의하여 가열하면 앞부분은 냉각 상태이고 뒷부분은 연료의 흐름에 의하여 가열되어 노즐에 의하여 분사시키면 연료가 일정온도 가열되어 있어 염폭발 전달이 골고루 이루어져서 최종 분사량까지 연소시킬 수 있어 불완전 연소에 의한 연료의 소모가 극히 적으며 엔진의 냉각 상태에서도 폭발이 양호하여 엔진에 진동을 줄일 수 있는 효과등이 있는 것이다.Each nozzle (2) and the fuel supply pump (3) associated with the fuel engine (3) standing on the diesel engine body (1) is formed with an extension (4a) at a predetermined position to fuel the non-ferrous metal heating element (5). When several of the supply pipes are molded into a single unit and power is supplied to the heating wires 7 installed on the outer periphery, the heating elements 5 are heated so that the fuel supply pipes 4 heat the extension 4a, while the fuel supply pipes 4 Heat is transferred to the heat transfer pipe 9 covering the fuel cell, so that the fuel passing through the fuel supply pipe 4 is heated to a predetermined temperature by the fuel supply pump 3 of the diesel engine. Since each of the inserted nozzles 2 is injected into the engine, the temperature of the injected fuel is heated to a temperature suitable for combustion, so the innocuous state is good, and the atomized fuel is always heated to a certain temperature so that it can be completely burned out in case of explosion. Exhaust from the diesel engine It is possible to reduce soot and toxic gas in the gas, and to obtain more engine power by complete combustion, and to attach the thermostat to the heating wire (7) that is installed on the outer periphery of the heating element (5). When the temperature of the supplied fuel is above a certain temperature, the power is automatically cut off. When the temperature of the fuel is lowered below a certain temperature, the power is supplied. Therefore, the fuel can be completely burned by supplying the fuel with a constant temperature. In addition, the fuel supply pump 3 has to maintain a high pressure, so that the expansion portion 4a of the fuel supply pipe 4 connected to the dense cooled state or the injection nozzle has to be heated. If heated by), the front part is cooled and the rear part is heated by the flow of fuel. When sprayed by nozzle, the fuel is heated to a certain temperature. Since the transmission is made evenly and the final injection amount can be combusted, the fuel consumption by incomplete combustion is extremely low, and the explosion is good even in the cooling state of the engine, thereby reducing the vibration in the engine.
