일반적인 자동차연료탱크는 연료흡입파이프가 연료탱크바닥에 위치하여 액체연료를 흡입 공급하도록 되어 있어, 연료탱크내의 오일유동압력과 오일하중압력으로 인하여 연료를 빨아들이는 흡인력과 그 압력의 가속력이 더하여 불규칙적으로 연료가 연소실에 공급케되므로 연소공기량과의 공연비가 적당치못하여 불완전연소는 물론 연료소모가 많고, 엔진의 소음 및 매연발생의 원인이 되었으므로 본 발명은 액체연료탱크저면에 별개의 연료공급실을 가지는 종지형 오일용기를 설치하고 격판으로 연료공급실을 구획하여 상부실과 하부실로 나누어서 연료공과 연료유출공을 통해 연료가 유입되게 하그 또 연료흡입파이프의 하단부를 별개의 하부실에 있게 설치고정함으로 가속압력이 없는 무압력상태에서 연료가 흡인공급되어지고 또 일정량의 연료공급으로 연소공기량과의 적절한 공연비의 유지가 이루어지도록 합 것이다.In general, the fuel tank of the automobile has a fuel intake pipe located at the bottom of the fuel tank to suck and supply liquid fuel.The oil suction pressure and the oil loading pressure in the fuel tank increase the suction force and acceleration of the pressure.

본 발명은 액체연료탱크내의 오일유동압력과 오일하중 압력이 연료흡입파이프를 통해 엔진연소실에 연료흡입될 때 가속력을 더하지 않도록 하여 안정된 연료흡입으로 연료탱크내의 연료가 엔진에 원활히 공급되도록 함으로 완전연소와 연료소모량을 감소시키고 자동차 엔진의 소음 및 매연발생을 최소화하도록 한 자동차 액체연료탱크의 연료공급창치에 관한 것이다.The present invention does not add acceleration when the oil flow pressure and the oil load pressure in the liquid fuel tank are sucked into the engine combustion chamber through the fuel intake pipe so that the fuel in the fuel tank can be smoothly supplied to the engine with stable fuel intake. And a fuel supply window of an automotive liquid fuel tank to reduce fuel consumption and minimize noise and soot generation of an automobile engine.

일반적으로 자동차등의 엔진에 연소에 필요한 액체연료(휘발유, 중유, 경유 등)를 공급하기 위한 액체연료탱크가 차체에 설비되어 있다. 또한 액체연료탱크에는 종래에 제 5도의 도시와 같이 액체연료탱크(30)의 내부저면위치에 연료흡입파이프(31)의 파이프하단부(31')가 고정되어 있으며, 그 파이프하단부(31')에는 휠타(32)가 부착되어서 액체연료탱크(30)내에 주입시킨 액체연료는 오일실(33)의 저면에 위치한 휠타(32)를 통해 연료흡입파이프(31)로서 엔진의 연소실에 연소공기와 함께 빨려들어 가게 되어 있다. 이때 빨려들어가는 액체연료는 도시하지 아니한 플로우트실(float chamber) 기화기, 벤투리관(Venthri tube)및 노즐(nozzle) 에서 분사되고 또 흡기밸브를 통해 액체연료가 연소실에 빨려 들어갈시에는 에어크리너를 통해 유입된 공기와의 공연비가 12.5:1 근부에서 최대에 이르고, 연료소비율은 공연비(空然比) 18:1 ∼ 16:1에서 최소가 된다. 그런데 액체연료탱크(30)를 비치한 자동차는 노상주행시에 차체가 움직임에 따라서 액체연료탱크(30)내에 주입시킨 액체연료가 동시 충동과 요동함으로 인하여 오일유동압력이 작용하고 또 액체연료탱크(30)내에 액체연료가 많이 들어 있을때는 압력에 의해 흡입연료가 많아지고 적어질때는 압력이 떨어지므로 흡입연료가 적어지게 된다. 오일압력은 오일유동상태와 오일량에 따라서 압력작용의 변화로 엔진에 빨려들어가는 연료공급량도 달라지게 된다.Generally, a liquid fuel tank for supplying liquid fuel (eg, gasoline, heavy oil, light oil, etc.) necessary for combustion to an engine such as an automobile is installed in a vehicle body. In addition, the lower end portion 31 'of the fuel suction pipe 31 is fixed to the liquid fuel tank at the inner bottom position of the liquid fuel tank 30, as shown in FIG. The liquid fuel injected into the liquid fuel tank 30 attached to the filter 32 is sucked together with the combustion air into the combustion chamber of the engine as the fuel suction pipe 31 through the filter 32 located at the bottom of the oil chamber 33. I am going to enter. At this time, the sucked liquid fuel is injected from a float chamber vaporizer, a Venturi tube and a nozzle (not shown), and when the liquid fuel is sucked into the combustion chamber through an intake valve, it is discharged through an air cleaner. The air-fuel ratio with the inflowed air reaches the maximum in the vicinity of 12.5: 1, and the fuel consumption ratio becomes the minimum in the air-fuel ratio 18: 1-16: 1. However, a vehicle having a liquid fuel tank 30 has an oil flow pressure due to simultaneous impulse and oscillation of the liquid fuel injected into the liquid fuel tank 30 as the vehicle body moves during road driving, and the liquid fuel tank 30 When there is a lot of liquid fuel in the tank, the suction fuel increases due to the pressure, and when the pressure decreases, the pressure drops. The oil pressure is changed according to the oil flow condition and the amount of oil, and the amount of fuel supplied to the engine is also changed.

또한 액체연료의 압력변동에 따라서는 연소실에 흡입되는 연료량도 달라져서 연료량과 공기량의 공연비가 일정하게 유지되지 못하는 문제점이 되었다.In addition, the amount of fuel sucked into the combustion chamber is also changed according to the pressure fluctuation of the liquid fuel, which is a problem that the air-fuel ratio of the fuel amount and the air amount cannot be kept constant.

또한 종래에 차량용 연료탱크에 있어서, 밀폐용기의 하부에 하부 탱크와 윈통체를 설치하고 연료흡입파이프 하단을 윈통체내에 있게 설치하여 2개의 통공으로 연료가 유통되게 하고 밀폐용기 저면에 2개의 연료유입공을 통해 하부 탱크 및 원통체에 연료 유입되어서 연료흡입파이프로 흡입공급하도록 된 것이 일본국 실용신안공보 소 472984호에 나온바 있다. 이는 저판 윈추통의 구멍을 통한 공기의 혼입이 방지되는 효과는 있으나 연료탱크내의 오일의 유동압력 및 오일량에 따르는 압력을 해소시키는데는 미급하그 2개의 연료유입공으로 인해 공기혼입의 연료유동이 일어나 일정량의 원활한 연료공급을 엔진연소실에 해주지 못한 결함이 있었다.Also, in the conventional fuel tank for vehicles, the lower tank and the win cylinder is installed in the lower part of the sealed container, and the lower part of the fuel suction pipe is installed in the win cylinder to allow the fuel to flow through the two through holes and the two fuel inflows to the bottom of the sealed container. The Japanese Utility Model Publication No. 472984 discloses that fuel is introduced into the lower tank and the cylindrical body through the ball to be sucked into the fuel suction pipe. This has the effect of preventing the mixing of air through the hole in the bottom plate winch cylinder, but the fuel flow of air mixing occurs due to the two fuel inlet holes which are not enough to relieve the pressure according to the flow pressure and oil volume of the oil in the fuel tank. There was a defect that could not supply a certain amount of smooth fuel to the engine combustion chamber.

이러한 종래 액체연료탱크의 사용으로서는 엔진에서 연료흡입에 따르는 연료량의 공급이 불안전하고 원활한 연료공급을 해주지 못함으로 인하여 완전연소가 되지 못하였고 연료소모량이 많고 엔진의 소음과 매연발생의 폐단이 있었으며 자동차의 주행성능이 떨어지는 문제점이 되었다.The use of such a conventional liquid fuel tank, the fuel supply due to the fuel intake in the engine is unstable and did not provide a smooth fuel supply, it was not completely burned, there is a lot of fuel consumption, the noise of the engine and the generation of soot, It was a problem of poor running performance.

그뿐 아니라 주입된 액체연료가 연료탱크내의 휠타수면에 있을때는 차체의 기울기에 따라 액체연료탱크가 같이 기울어져서 액체연료가 빨려들어가는 량이 적을 때는 차량의 추진력이 떨어지는 경우도 있으며 또 엔진의 가동이 꺼지는때도 있어 자동차운전에 어려움이 있는 문제점도 있었다.In addition, when the injected liquid fuel is at the wheel surface of the fuel tank, the propulsion of the vehicle may drop when the liquid fuel tank is inclined together according to the inclination of the vehicle so that the amount of liquid fuel is sucked in, and when the engine is turned off. There was also a problem with difficulties in driving a car.

본 발명은 그러한 문제점을 해소하기 위한 것으로 기존의 액체연료탱크의 밑면에 일정한 크기의 연료공급실을 별개로 설치함에 있어서, 그 연료공급실의 중간부에 곡면을 이룬 격판으로 구획설치하여 상부실과 하부실로 나누고 그 상부실과 하부실은 액체연료탱크의 저면에 뚫은 단 1개의 연료유출공과 격판에 뚫은 단 1개의 연료공을 통해 액체연료가 각각 상쇠된 위치에서 유입되도록 하고, 또 연료흡입파이프 하단부의 휠타는 연료공급실의 하부실위치에 있게 설치함으로, 격판에 의거한 상부실과 하부실로 나누어지고 연료흡입시에는 연료흡입파이프 하단과의 사이에는 액체연료탱크내의 오일유동압력 및 오일하중압력이 더하지 않는 연소실인 격판밑의 하부실에 공기층이 이루어지게 되어 엔진의 연소실에 연료가 빨려들어갈때에는 상기의 압력이 더하지 않는 상태에서 연료흡입에 따르는 일정량의 연료가 흡입케되므로, 공기량에 알맞는 연료량을 엔진에 공급할 수가 있고 또 공연비 12.5:1 근부에서 최대에 이르도록 하므로 완전연소가 가능할 뿐 아니라 종래에 비하여 연료소모량이 적어 연료절감을 기할 수가 있다.The present invention is to solve such a problem to install a fuel supply chamber of a certain size separately on the bottom of the existing liquid fuel tank, divided into an upper chamber and a lower chamber by partitioned by a partition plate formed in the middle of the fuel supply chamber The upper and lower chambers allow the liquid fuel to flow from the offset position through only one fuel outlet hole drilled in the bottom of the liquid fuel tank and only one fuel hole drilled in the diaphragm. It is divided into the upper chamber and the lower chamber based on the diaphragm, and when the fuel is sucked in, the diaphragm which is the combustion chamber which does not add the oil flow pressure and oil load pressure in the liquid fuel tank between the lower end of the fuel intake pipe. When the fuel is sucked into the combustion chamber of the engine is formed in the lower chamber of the above pressure In this state, a certain amount of fuel is sucked by the fuel intake, so that the engine can supply the amount of fuel suitable for the amount of air and reaches the maximum at around 12.5: 1 of the air-fuel ratio. Low fuel consumption can save fuel.

또한 연소실에서의 완전연소는 자동차의 주행성능을 향상시키고 또 엔진에 안정을 가져오고 소음이 적어지며, 매연이 떨어지므로 자동차등의 주행이 순조롭게 되도록 함에 목적이 있다.In addition, the complete combustion in the combustion chamber aims to improve the running performance of the car, bring stability to the engine, reduce noise, and reduce the smoke so that the running of the car is smooth.

또한 본 발명은 엔진의 연소실에 종래에 불규칙적으로 빨려 들어가는 연료량을 규칙적인 상태에서 균일유입되어지게 하므로 연료소모량을 줄이고 연료절감을 기할 수 있도록 함에 그 목적이 있다.In addition, the present invention is to be uniformly introduced in a regular state of the fuel amount that is conventionally sucked into the combustion chamber of the engine has an object to reduce the fuel consumption and to reduce the fuel.

본 발명의 또 다른 목적은 본 발명의 구조를 기존의 액체연료탱크 밑면에 간단한 구성으로 설치하여 저렴하게 제공할 수 있도록 하며 또 손쉽게 분해시켜서 액체연료의 찌꺼기 및 불순물을 청소제거할 수있도록 함에 그 목적이 있다.Another object of the present invention is to install the structure of the present invention in a simple configuration on the bottom of the existing liquid fuel tank to provide inexpensively and to easily decompose to clean and remove the residue and impurities of the liquid fuel There is this.

이하 본 발명을 첨부 도면에 따라 그 실시예를 상세히 설명하면 다음과 같다.Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

자동차등의 엔진(3) 연소실에 액체연료를 흡입 공급시키기 위하여 연료흡입파이프(2)와 오버플로파이프(4)로서 연결되는 액체연료탱크(1)에 있어서, 그 액체연료탱크(1)의 저면외부에 별개의 종지형 오일용기(9)를 착탈가능하게 설치하기 위한 고정테(7)를 부착설치하여 고정테(7)의 나선부(8)에 패킹(5)을 대고 종지형 오일용기(9)의 내면 나사를 체결조립하되 종지형 오일용기(9)내에 곡면을 이룬 격판(10)을 내장설치하여 연료공급실(6)에 상부실(11)과 하부실(12)로 상하로 분리되게 형성하고 또 액체연료탱크(1)의 저면에서 상부실(11)로 유통하는 연료유출공(13)과 상부실(11)에서 하부실(12)에 유통되는 연료공(14)을 액체연료탱크(1)의 바닥과 격판(10)의 반대된 위치에 각각 1개씩 뚫어 액체연료탱크(1)익 연료가 이들 연료유출공(13)및 연료공(14)을 통해 상부실(11)과 하부실(12)에 각각 유입되어지도록 하였다. 이는 연료흡입 파이프(2)로부터의 연료흡인에 의해서만 하부실(12)에 연료가 충족케 되어지며 연료유출공(13)과 연료공(14)의 직경은 연료흡입파이프(2)익 내경과 같은 싸이즈로하여 연료일정량의 흡입과 공급이 이루어지게 한 것이다. 또한 연료흡입파이프(2)의 하단부(2')는 하부실(12)위치에 있게 설치하고 끝에 휠타(15)를 부착하였다. 이는 외부에서 종지형 오일용기(9)를 틀어 분해하면 내부의 격판(10)과 오일용기(9)는 쉽게 분리되므로 액체연료의 찌꺼기를 쉽게 제거청소하그 다시 체결조립할 수가 있는 구조로 하였다.In a liquid fuel tank 1 connected as a fuel intake pipe 2 and an overflow pipe 4 for sucking and supplying liquid fuel to a combustion chamber of an engine 3 such as an automobile, the bottom surface of the liquid fuel tank 1 Attach the fixed frame (7) for detachably installing the separate vertical oil container (9) on the outside, attach the packing (5) to the spiral portion (8) of the fixed frame (7) and the vertical oil container (9) Fasten and assemble the inner surface of the internal oil container (9) of the inner surface of the curved plate (10) is installed inside the fuel supply chamber (6) formed to be separated into the upper chamber 11 and the lower chamber 12 up and down, and The fuel outlet hole 13, which flows from the bottom of the liquid fuel tank 1 to the upper chamber 11, and the fuel hole 14, which is distributed from the upper chamber 11 to the lower chamber 12, is connected to the liquid fuel tank 1. The fuel of the liquid fuel tank 1 is drilled into the upper chamber 11 through these fuel outlet holes 13 and the fuel holes 14 by drilling one at a position opposite to the bottom of the diaphragm and the diaphragm 10. And to be introduced into the lower chamber 12, respectively. The fuel is filled in the lower chamber 12 only by the fuel suction from the fuel suction pipe 2, and the diameter of the fuel outlet hole 13 and the fuel hole 14 is equal to the inside diameter of the fuel suction pipe 2. The size was used to draw and supply a certain amount of fuel. In addition, the lower end portion 2 'of the fuel suction pipe 2 was installed in the lower chamber 12 position, and the filter 15 was attached to the end thereof. This is because the diaphragm 10 and the oil container 9 are easily separated when the vertical oil container 9 is disassembled from the outside, so that the residue of the liquid fuel can be easily removed and then reassembled and assembled.

또한 본 발명은 제 4도의 단면도와 같은 구조로 실시할 수도 있다.In addition, the present invention can also be implemented in the same structure as the cross-sectional view of FIG.

제 4도는 본 발명에 있어 액체연료탱크(1)에 연료공급실(6)을 설치한 구성을 나타낸 다른 실시예의 단면도이다.4 is a cross-sectional view of another embodiment showing the configuration in which the fuel supply chamber 6 is provided in the liquid fuel tank 1 in the present invention.

별도의 연료공급실(6)을 설치하기 위하여 액체연료탱크(1)의 저면에 긴나사봉(16)을 고정시키고 그 긴나사봉(16)을 이용하여 격판(10)과 종지형 오일용기(9)를 각각 끼워 너트(17)(17')로 체결하여 설치하고 패킹(5')을 대서 기밀을 유지하도록 하였으며 또한 연료유출공(13) 연료공(14)및 연료흡입파이프(2)의 하단부(2')는 상기와 같은 구성으로 제 3도와 같이 구성하였다. 또한 본 발명을 실시함에 있어서는 격판(10)을 여러개 연료공급실(6)에 구획설치하여 여러단의 오일실을 분활구성시킬수도 있으므로 상부실과 하부실로 한정하지 않는다.In order to install a separate fuel supply chamber 6, the long screw rod 16 is fixed to the bottom surface of the liquid fuel tank 1, and the diaphragm 10 and the vertical oil container 9 are respectively formed using the long screw rod 16. Fitting and tightening with nuts (17) and (17 ') and packing (5') to maintain airtightness, and also the fuel outlet hole (13) and the lower end (2 ') of the fuel hole (14) and the fuel suction pipe (2). ) Is configured as shown in FIG. 3 with the above configuration. In addition, in the practice of the present invention, since the diaphragm 10 may be partitioned in several fuel supply chambers 6, the oil chambers may be divided into several stages, and thus the upper and lower chambers are not limited.

도면중 미설명부호 18은 공급펌프, 19는 연료여과기이다.In the drawings, reference numeral 18 denotes a supply pump, and 19 denotes a fuel filter.

이와 같이 된 본 발명은 액체연료를 주입하게 된 액체연료탱크(1)의 저면에 종지형 오일용기(9)로서 연료공급실(6)을 별도 구성하고 있으며 또, 그 연료공급실(6)은 오일용기(9)내의 격판(10)으로 또한 구획되어 상부실(11)과 하부실(12)로 분리되어 단 1개의 연료유출공(13)과 단 1개의 연료공(14)을 통해 연료가 유입되어지고 또 연료흡입파이프(2)를 통해 엔진(3)에서의 연료흡입량만큼 공급케 된다.According to the present invention, the fuel supply chamber 6 is separately configured as a vertical oil container 9 at the bottom of the liquid fuel tank 1 into which the liquid fuel is injected, and the fuel supply chamber 6 includes an oil container ( 9 is also partitioned into the diaphragm 10 in the upper chamber 11 and the lower chamber 12 to separate the fuel flow through only one fuel outlet hole 13 and only one fuel hole 14 In addition, the fuel intake pipe 2 is supplied by the amount of fuel intake from the engine (3).

따라서 격판(10)으로 분활된 상부실(11)과 하부실(12)에는 공기층인 연료공급층이 형성되어지므로 이 공기층은 액체연료탱크(1)내의 오일유동압력 및 오일하중압력에도 가속력 및 가압력을 더하지 않는 물리적인 힘의 완충작용을 하므로 하부실(12) 위치에 고정되어 있는 연료흡입파이프(2) 하단부(2')의 휠타(15)를 통해서 빨려들어가는 연료는 오일유동에 의한 가속력 및 연료량의 가속압을 더하지 않는 균일 연료량이 빨려들어가게 되므로, 연소공기량에 알맞는 연료량의 공급이 이루어지고 또 엔진 연소실에서의 완전연소의 효과를 가져오고 또 과량의 연료공급이 해소케되므로 연료소모량을 억제하여 연료절감의 효과를 얻을수가 있다.Therefore, since the fuel supply layer as an air layer is formed in the upper chamber 11 and the lower chamber 12 divided by the diaphragm 10, the air layer is accelerated and pressed even in the oil flow pressure and oil load pressure in the liquid fuel tank 1. The fuel sucked through the filter 15 of the lower end portion 2 'of the fuel intake pipe 2 fixed to the lower chamber 12 position acts as a buffer of the physical force without adding the pressure. Since the uniform fuel amount which does not add the acceleration pressure of the fuel amount is sucked in, the fuel amount suitable for the combustion air amount is supplied, and the effect of complete combustion in the engine combustion chamber is achieved, and the excess fuel supply is eliminated, thereby reducing the fuel consumption amount. By suppressing, the effect of fuel saving can be obtained.
