내연기관의 연료 예열장치 {Fuel preheating system of internal combustion engines}Fuel preheating system of internal combustion engines

본 발명은 내연기관의 연료 예열장치에 관한 것으로서, 더욱더 상세하게는 연료탱크에 보관중인 연료가 일정온도로 예열된 상태에서 엔진으로 공급되어 완전연소가 이루어지도록 하는 내연기관의 연료 예열장치에 관한 것이다.The present invention relates to a fuel preheater of an internal combustion engine, and more particularly, to a fuel preheater of an internal combustion engine such that fuel stored in a fuel tank is supplied to an engine in a state where it is preheated to a predetermined temperature to complete combustion. .

일반적으로 화석연료를 사용하는 대부분의 엔진은 연료탱크에 주유된 연료를 펌핑시키는 연료펌프와, 연료중에 함유되어 있는 이물질을 걸러주는 여과기 및 연료분사기를 거쳐 엔진에 공급되면서 연소되고 있다.In general, most engines using fossil fuel are burned while being supplied to the engine through a fuel pump for pumping fuel in a fuel tank, a filter and a fuel injector to filter foreign substances contained in the fuel.

상기 연료는 정제시 함유된 조성물에 따라 연소효율의 등급에 많은 차이가 발생되었으나, 기후 및 온도등의 외부적인 요인에 의해서도 연소효율에 영향을 받 게되었다.The fuel has a lot of difference in the grade of combustion efficiency according to the composition contained in the purification, but the combustion efficiency is also affected by external factors such as climate and temperature.

즉, 온도가 낮은 상태에서는 연료의 점화율이 떨어지면서 불완전연소가 발생됨에 따라 공해물질인 산화탄소 및 아황산가스등의 매연을 유발하게 되었고, 특히 연료의 소모량이 증가하는 반면 엔진의 출력은 저하되는 문제점이 있었다.That is, in the state of low temperature, as the ignition rate of the fuel decreases and incomplete combustion is generated, it causes soot such as carbon oxide and sulfur dioxide, which are pollutants. There was this.

한편, 종래에도 온도의 저하로 인하여 연료에 미치는 영향을 억제하고 연소효율을 향상시키기 위한 방법으로 엔진을 냉각시키는 냉각수를 이용하여 이의 열교환작용에 의해 연료를 예열시키도록 하고 있다.On the other hand, conventionally, in order to suppress the influence on the fuel due to the temperature decrease and to improve the combustion efficiency, the fuel is preheated by the heat exchange action thereof using the cooling water for cooling the engine.

그러나 이 역시도 냉각수가 미쳐 더워지지 않은 상태에서 엔진을 초기 시동시에는 연료를 예열시키는 것이 불가능하게 되는 문제점이 있었다.However, this also has a problem that it is impossible to preheat the fuel at the initial start of the engine in the state that the coolant is not warm.

본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해, 일측단부가 라디에이터로 물이 공급되는 라디에이터입구에 연결되는 출구가 형성되고, 타측단부에는 라디에이터로 부터 물이 배출되는 라디에이터출구에 연결되는 입구가 형성되며, 내부에는 라디에이터출구를 통해 배출된 물이 담겨진 후 라디에이터입구를 통해 라디에이터로 공급되도록 하는 수납부가 형성된 순환파이프와, 상기 순환파이프의 수납부에 담겨진 물과 열교환이 이루어지면서 연료탱크에 보관중인 연료가 엔진으로 공급되도록 설치되는 연료관과, 상기 연료관을 통해 엔진으로 공급되는 연료의 온도가 일정치 이하인 경우 밧데리로 부터 전원을 공급받아 열을 발생시키면서 연료의 온도가 일정온도로 상승되도록 하는 히터트레싱과, 상기 연료관을 흐르는 연료가 순환파이프의 수납부에 담겨진 물과 열교환이 이루어지면서 일정치 이상의 온도로 상승하는 경우 히터트레싱으로 공급되는 밧데리의 전원이 차단되도록 하는 센서로 구성하여, 겨울철등과 같이 주위 온도가 낮은 곳에서 엔진을 초기 시동시에도, 상기 엔진으로 공급되는 연료가 일정온도로 상승된 후 공급됨으로서, 온도의 영향으로 인한 불완전연소가 방지되고, 최적상태에서 연료를 연소시키게 됨으로서 매연등의 공해물질의 배출이 방지됨은 물론, 연소효율의 증대로 연료의 소모량이 줄어들게 되고, 엔진의 출력이 향상되도록 하는 내연기관의 연료 예열장치를 제공하는 데 있다.An object of the present invention is to solve the same problem as the conventional, the outlet is connected to the radiator inlet is connected to the radiator inlet one end is supplied water to the radiator, the other end is the inlet connected to the radiator outlet is discharged water from the radiator Is formed, the inside of the circulation pipe formed with a receiving portion for receiving the water discharged through the radiator outlet is supplied to the radiator through the radiator inlet, and the heat exchanged with the water contained in the receiving portion of the circulation pipe is stored in the fuel tank The fuel pipe is installed to supply the engine to the engine, and if the temperature of the fuel supplied to the engine through the fuel pipe is lower than a predetermined value, the fuel temperature is raised to a constant temperature while generating heat by receiving power from the battery. Heater tracing, and the fuel flowing through the fuel pipe is a circulating wave It is composed of a sensor that cuts off the power of the battery supplied to the heater tracing when the temperature rises above a certain value while the heat exchanged with the water contained in the storage part of the pump, and the engine is started at a low ambient temperature such as in winter.

An inlet 12 is formed to be connected to the radiator outlet through which water is discharged, and a circulation pipe 10 having an accommodating part 13 configured to receive water discharged through the radiator outlet and to be supplied to the radiator through the radiator inlet is formed therein. And, the fuel pipe 20 is installed so that the fuel stored in the fuel tank is supplied to the engine while the heat exchange with the water contained in the receiving portion 13 of the circulation pipe 10 and the fuel pipe 20 through When the temperature of the fuel supplied to the engine is lower than a certain value, the power is supplied from a battery (not shown) to generate heat, thereby raising the temperature of the fuel to a predetermined temperature. When the fuel flowing through the tresing 30 and the fuel pipe 20 rises to a temperature higher than or equal to a predetermined value while undergoing heat exchange with water contained in the accommodating portion 13 of the circulation pipe 10, the fuel is supplied to the heater tressing 30. It is a basic feature of the technical configuration that the sensor 40 is configured to be cut off the power of the battery.

한편, 상기 히터트레싱(30)은 도 2에 도시하고 있는 바와 같이, 일측단부가 엔진으로 연료를 공급하는 연료파이프(50)에 연결되고 타측단부가 연료탱크로 부터 공급되는 연료가 이송되도록 하는 연료파이프(50)에 연결된 연료관(20)의 내부에 설치됨을 밝혀 둔다.Meanwhile, as shown in FIG. 2, the heater tracing 30 has one end connected to a fuel pipe 50 for supplying fuel to the engine and a fuel for transporting the fuel supplied from the fuel tank to the other end. Note that it is installed inside the fuel pipe 20 connected to the pipe 50.

이와같이 구성되는 본 발명은, 엔진을 초기 시동시, 순환파이프(10)의 내부에 담겨진 물의 온도를 센서(40)가 감지하여 일정치 이하이면, 상기 센서(40)가 연료관(20)의 내부에 설치된 히터트레싱(30)으로 밧데리의 전원을 공급하여 열을 발생하도록 함으로서, 상기 연료관(20)을 흐르는 연료의 온도가 일정온도로 상승된 상태로 연료파이프(50)를 통해 연료관(20)으로 유입된 연로가 연료파이프(50)를 통해 엔진으로 공급된다.According to the present invention configured as described above, when the sensor 40 detects the temperature of the water contained in the circulation pipe 10 at the initial start of the engine and is lower than a predetermined value, the sensor 40 is inside the fuel pipe 20. By supplying power to the battery to the heater tracing (30) installed in the heat generating, the fuel pipe 20 through the fuel pipe 50 in a state in which the temperature of the fuel flowing through the fuel pipe 20 is raised to a predetermined temperature Fuel flow into the () is supplied to the engine through the fuel pipe (50).

한편, 상기와 같이 연료가 공급되는 것에 의해 엔진이 일정시간 운행되면 상기 엔진이 일정온도로 상승하지 않도록 순환되는 물의 온도가 상승되면서 순환파이프(10)의 수납부(13)로 라디에에이터의 라디에이터출구를 통해 배출된 물이 입구(12)를 통해 유입되면서 연료관(20)을 흐르는 연료가 열교환이 이루어지면서 일정치 온도로 상승하게 된다.On the other hand, when the engine is run for a predetermined time by the fuel supply as described above, the temperature of the water circulated so that the engine does not rise to a certain temperature is raised while the radiator of the radiator to the receiving portion 13 of the circulation pipe 10 As water discharged through the outlet flows through the inlet 12, the fuel flowing through the fuel pipe 20 rises to a predetermined temperature as heat exchange occurs.
