Abstract

PURPOSE: A diesel fuel filter is provided to prevent filter paper from error in start by the sudden fall of temperature in winter. CONSTITUTION: A fuel filter(10) has an alarm lamp sensor for alarming a user of the water level of removed water. Fuel flows through an inlet(12) of an upper head(11) to be filtered in filter paper(15) and to be discharged to an outlet(13). The head has a passage(14) for flowing the fuel between the inlet and the central passage of the filter paper. Then the filtered fuel by the filter paper is supplied to an engine through the outlet. Herein, water is removed and the alarm lamp sensor is lighted on at the proper water level. A heater(20) is positioned at the passage for flowing fuel into the head. The heater is turned on when a bimetal(21) detects the temperature lower than a set temperature of 5 degrees below zero. Therefore, fuel is filtered in the filter paper after a solid material including paraffin is molten when temperature plummets down in winter.

Description

디젤연료필터 {Diesel fuel filter}Diesel fuel filter

본 발명은 디젤연료필터에 관한 것으로, 더 상세하게는 동절기 기온 급강하시여 발생되는 파라핀 석출로 인한 필터막힘을 미연에 방지할 수 있도록 발명된 것이다.The present invention relates to a diesel fuel filter, and more particularly, it is invented to prevent the filter clogging due to the precipitation of paraffin generated during a sudden winter temperature drop.

일반적으로, 차량은 연료탱크속의 연료를 필터로 여과하여 인젝션 펌프로 보내서 엔진의 운전상태에 따라 연료의 분사량 및 분사시간을 제어하는 연료장치가 구비되어 있다.In general, the vehicle is equipped with a fuel device for filtering the fuel in the fuel tank with a filter to send to the injection pump to control the injection amount and injection time of the fuel in accordance with the operating state of the engine.

연료필터의 기능은 연료속의 먼지, 수분을 제거하는 것인데, 특히 디젤엔진에서는 연료에 의해 인젝션 펌프, 노즐등이 윤활되고 있으므로 충분한 여과능력이 필요하기 때문에 용량은 크게 되어 있다.The function of the fuel filter is to remove dust and water in the fuel. Especially in diesel engines, injection pumps and nozzles are lubricated by fuel, so the capacity is large because sufficient filtration capacity is required.

또, 연료속의 수분을 제거하기 위한 연료수분 분리기가 있으며, 세디멘터 내부에는 수위를 알리는 수위센서도 구비되어 있다.In addition, there is a fuel moisture separator for removing moisture in the fuel, and a water level sensor for notifying the water level is provided inside the sedimenter.

필터 엘리먼트에는 여과지, 여과포등이 있으나 여과지가 일반적으로 널리 사용되고 있다.Filter elements include filter paper, filter cloth, and the like, but filter papers are generally widely used.

오버플로밸브는 연료 피드펌프에서의 송류압력이 규정에 달했을 때 열리며, 여분의 연료가 탱크로 되돌아가도록 되어 있으며, 플렉시블 파이프의 접속부 및 ㅈ필터등에 무리가 가해지는 것을 방지하고 있다.The overflow valve is opened when the flow pressure in the fuel feed pump reaches the prescribed value, and the excess fuel is returned to the tank, preventing excessive force from being connected to the flexible pipe connection and the filter.

그리고, 연료중에 공기가 혼입된 경우에도 오버플로 밸브에서 연료와 함께 공기가 외부로 배출하도록 구성되어 있다.Also, even when air is mixed in the fuel, the overflow valve is configured to discharge air to the outside together with the fuel.

한편, 연료필터는 동절기에 기온급강하시, 예로서 -15℃이하일 때는 연료에 포함된 파라핀이 석출되는데, 이 파라핀은 포화탄화수소의 응고로 석출되어 필터주위를 막혀지게 한다.On the other hand, the fuel filter during the winter season when the temperature drops, for example, below -15 ℃ precipitates the paraffin contained in the fuel, this paraffin precipitates due to the solidification of saturated hydrocarbon to block the surroundings of the filter.

이와같이 파라핀에 의해 여과지(15)주위가 응고되면 시동불량이 발생되는 등의 문제점이 있었던 것이다.As such, when the surroundings of the filter paper 15 are solidified by paraffin, there is a problem such as starting failure.

본 발명의 목적은 동절기 기온급강하시에도 파라핀의 석출을 미연에 방지하여 시동불량의 염려가 없는 디젤연료필터를 제공하는데 있다.An object of the present invention is to provide a diesel fuel filter that does not worry about starting failure by preventing the precipitation of paraffin in advance even during a sudden winter temperature drop.

본 발명의 다른 목적은 필터의 신뢰성과 상품성이 향상되도록 한 디젤연료필터를 제공하는데 있다.Another object of the present invention is to provide a diesel fuel filter to improve the reliability and commerciality of the filter.

이러한 본 발명의 목적은 헤드(11)의 인입구(12)를 통해 유입된 연료가 여과지(15)를 거쳐 출구(13)로 배출토록 하고, 하부에 수분리 경고등센서(16)가 구비되는 여과필터(10)에 있어서;The purpose of the present invention is such that the fuel introduced through the inlet 12 of the head 11 is discharged to the outlet 13 via the filter paper 15, the filtration filter is provided with a water separation warning light sensor 16 at the bottom In (10);

상기 헤드(11)의 내부로 연료가 통과되는 통로(14)에 바이매탈(21)에 의해 설정온도 이하에서 전기를 인가하여 발열하는 히터(20)가 설치되는 것에 의해 달성된다.This is achieved by providing a heater 20 that generates electricity by applying electricity at or below a set temperature by the bimetal 21 in the passage 14 through which fuel passes through the head 11.

따라서, 특히 동절기에 기온급강하에 의한 파라핀 석출로 여과지(15)가 막혀 시동불량이 발생되는 것을 미연에 방지할 수가 있다.Therefore, in particular, it is possible to prevent the start of the starting failure due to the blockage of the filter paper 15 due to the precipitation of paraffin due to the temperature drop during the winter season.

또, 차량의 상품성과 신뢰성이 향상된다.In addition, the merchandise and reliability of the vehicle are improved.

이하 첨부된 도면에 의거하여 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 통상의 연료필터(10)를 일부 절결하여 도시하고, 도 3은 본 발명의 히터(20)가 헤드(11) 내부 통로(14)에 설치되는 상태를 간략도로 도시하고 있다.FIG. 1 is a partial cutaway view of a conventional fuel filter 10, and FIG. 3 schematically illustrates a state in which the heater 20 of the present invention is installed in the internal passage 14 of the head 11.

연료필터(10)는 도 1에서와 같이 상부 헤드(11)의 인입구(12)를 통해 유입된 연료가 여과지(15)에서 여과된 후 출구(13)로 배출되는 것이며, 이때 제거된 수분의 수위를 감지하여 경고하는 수분리 경고등센서(16)가 구비되어 있다.The fuel filter 10 is a fuel introduced through the inlet 12 of the upper head 11 is discharged to the outlet 13 after being filtered in the filter paper 15, as shown in Figure 1, wherein the water level of the water removed Water separation warning light sensor 16 for detecting and warning is provided.

헤드(11)는 인입구(12)와 여과지(15)의 중앙 통로로 연료가 이동되도록 하는 그 사이에 통로(14)가 형성되며, 여과지(15)에서 여과된 연료가 출구(13)를 통해 엔진으로 공급되는 것이다.The head 11 has a passage 14 formed between the inlet 12 and the central passage of the filter paper 15 so that the fuel can be moved, and the fuel filtered from the filter paper 15 passes through the engine 13 through the outlet 13. To be supplied.

이때 수분도 여과되며 적정 수위에 도달하면 수분리 경고등센서(16)가 점등하게 된다.At this time, the water is also filtered and the water separation warning light sensor 16 is turned on when the water level is reached.

상기 히터(20)는 헤드(11)의 내부로 연료가 통과되는 통로(14)에 위치되어 전기적으로 연결된 바이매탈(21)에 의해 설정온도 이하(통상 -5℃ 이하)에서 전기를 "ON"으로 인가하여 발열하도록 작동된다.The heater 20 is located in a passage 14 through which fuel passes into the head 11, and is turned “ON” at or below a set temperature (usually -5 ° C. or lower) by a bimetal 21 that is electrically connected. It is applied to generate heat.

따라서, 동절기등에 기온 급강하로 연료온도가 저하될 때 그 온도를 상승시키므로써 파라핀과 같은 응고물질이 형성되더라도 용용된 후 여과지(15)를 통과토록 하믈서, 여과공에서 응고로 인해 막히는 것을 미연에 방지할 수가 있는 것이다.Therefore, when the fuel temperature is lowered due to a sudden drop in temperature in winter, the temperature is raised so that even if a coagulant such as paraffin is formed, it is allowed to pass through the filter paper 15 after it is dissolved. It can be prevented.

상기 히터(20)는 전기발열에 의한 것이면 어떤것도 만족하나 세라믹히터가 내구성과 부피 및 전기소모성면에서 바람직 하다.The heater 20 satisfies anything as long as it is caused by electric heat, but a ceramic heater is preferable in terms of durability, volume, and electrical consumption.

이 세라믹히터는 1개에 약 60W 의 저항을 가지게 되며 2-3개를 하나의 셋트로 설치하게 되며, 시동점화시에만 전기적으로 "ON"되고 설정온도(예로서-5℃)이하에서 작동되도록 제어하는 것이다.This ceramic heater has a resistance of about 60W in one and installs 2-3 in one set. It is electrically turned on only at start-up and operated under the set temperature (eg -5 ℃). To control.

상기와 같은 본 발명에 의하면, 따라서, 특히 동절기에 기온급강하에 의한 파라핀 석출로 여과지(15)가 막혀 시동불량이 발생되는 것을 미연에 방지할 수가 있다.According to the present invention as described above, therefore, it is possible to prevent the start of the start failure due to the blockage of the filter paper 15 due to the precipitation of paraffin due to a sudden drop in temperature during the winter season.

또, 차량의 상품성과 신뢰성이 향상되는 등의 매우 유용한 발명인 것이다.Moreover, it is a very useful invention such that the merchandise and reliability of the vehicle are improved.
