Description

엘피아이 차량 봄베의 연료 리턴소음 방지장치{apparatus for protecting fuel return noise in bombe of liquefied petroleum gas injection vehicles}Apparatus for protecting fuel return noise in bombe of liquefied petroleum gas injection vehicles}

본 발명은 엘피아이 차량의 연료 리턴장치에 관한 것으로, 특히 리턴되는 연료에 의해 봄베의 내부에서 소음이 발생하는 것을 방지할 수 있도록 된 엘피아이차량 봄베의 연료 리턴소음 방지장치에 관한 것이다.The present invention relates to an Elpia vehicle fuel return device, and more particularly, to an apparatus for preventing fuel return noise of an Elpia vehicle vehicle, which is capable of preventing noise from being generated inside the cylinder by the returned fuel.

연료비용이 저렴하다는 장점에 더하여 충전소의 확충이 이루어지면서 점차 엘피지(liquefied petroleum gas)차량의 사용이 늘어나고 있는 추세이다.In addition to the low fuel cost, the use of liquefied petroleum gas vehicles is gradually increasing as the filling stations are expanded.

엘피지를 사용하는 차량에는 액체상태의 엘피지를 저장하는 용기인 봄베가 구비되어 있고, 이 봄베의 엘피지는 베어퍼라이저에서 기화되어 믹서라고 불리우는 혼합장치에서 외기와 혼합된 후 흡기매니폴드를 거쳐 각 연소실로 공급되고 있다.A vehicle using Elpji is equipped with a bomb, which is a container for storing liquid Elpgi, which is vaporized in a bearer, mixed with outside air in a mixing device called a mixer, and then passed through an intake manifold to each combustion chamber. It is supplied by.

또한 최근에는 한 걸음 더 나아가 보다 정밀한 연료 공급량 조절을 위해서 각 연소실마다 엘피지를 직접 분사하는 엘피아이(liquefied petroleum gas injection)방식의 엔진을 탑재한 엘피아이 차량의 사용도 점차 증가하고 있는 추세이다.In addition, the use of Elpiai vehicles equipped with an liquefied petroleum gas injection (LPIA) engine that directly injects Elpji into each combustion chamber in order to more precisely control the fuel supply is increasing.

한편, 직분식 연료 분사 타입의 엔진에서는 인젝터로 과도공급된 연료가 다시 연료탱크(엘피지 엔진에서는 봄베)로 리턴되도록 되어 있는 바, 이는 엘피아이 엔진에 있어서도 마찬가지이며, 과도공급된 연료는 도 1 및 도 2에 도시된 바와 같이 봄베(1)에 삽입 설치된 리턴파이프(2)를 통해 상기 봄베(1)의 내부로 돌아오게 된다.(미설명 부호 3은 연료펌프, 4는 멀티밸브, 5는 셧-오프(shut-off)밸브, 6은 연료공급파이프이다.)On the other hand, in the direct fuel injection type engine, the fuel that is oversupplied to the injector is returned to the fuel tank (bomb in the Elpji engine), which is the same in the Elpia engine, and the oversupplied fuel is illustrated in FIGS. As shown in FIG. 2, the cylinder 1 is returned to the inside of the cylinder 1 through a return pipe 2 installed in the cylinder 1 (not shown 3 is a fuel pump, 4 is a multi-valve, and 5 is a shut down). Shut-off valve, 6 is the fuel supply pipe.)

그런데, 엘피아이 엔진에서 리턴되는 연료는 엔진룸을 돌아오는 동안에 열을 흡수하여 그 일부가 기화함으로써 액체와 기체의 혼합상태로 된다.By the way, the fuel returned from the engine of Elpia is absorbed by the heat while returning from the engine room, and part of it vaporizes, thus mixing with liquid and gas.

따라서, 상기 리턴파이프(2)의 하단으로부터 봄베(1)의 내부로 유입될 때 리턴파이프(2)의 길이와 봄베(1) 내부의 연료 충전량에 따라 액체상태의 연료가 떨어지는 소리 및 기체상태의 연료가 부상하는 소리 등의 소음이 발생하는 문제점이 있었다.Therefore, when the liquid flows from the lower end of the return pipe 2 into the interior of the cylinder 1 and the fuel in the liquid state and the gaseous state of the liquid drop according to the length of the return pipe 2 and the fuel filling amount inside the cylinder 1 There was a problem that noise such as the sound of fuel rise.

즉, 도 1에서와 같이 리턴파이프(2)가 봄베(1)의 바닥면에 가까운 위치까지 설치되어 있는 경우에는 봄베(1)내 충전연료량의 많고 적음에 상관없이 리턴되는 액체연료에 의해서는 소음이 발생하지 않고 충전연료량이 많을 때 리턴되는 기체연료에 의해서 소음이 발생하게 된다. 즉, 리턴파이프(2)의 단부에서 배출된 기체연료가 기포상태로 충전연료의 상면까지 부상하면서 소음이 발생하게 된다.That is, as shown in FIG. 1, when the return pipe 2 is installed to a position close to the bottom surface of the cylinder 1, noise is caused by the liquid fuel returned regardless of the large or small amount of fuel charged in the cylinder 1. This does not occur and noise is generated by the gas fuel returned when the amount of charged fuel is large. That is, noise is generated while the gaseous fuel discharged from the end of the return pipe 2 rises to the upper surface of the charged fuel in a bubble state.

또한, 도 2에서와 같이 리턴파이프(2)의 단부가 봄베(1)의 상부에 위치해 있는 경우에는 리턴되는 기체연료에 의해서는 소음이 발생하지 않고, 충전연료량이 적을 때 리턴파이프(2)의 단부에서 배출된 액체연료가 아래쪽의 충전연료 상면에 떨어져 내리면서 소음이 발생하게 된다.In addition, when the end of the return pipe (2) is located above the cylinder (1) as shown in FIG. 2, no noise is generated by the returned gas fuel, and when the amount of fuel charged is small, As the liquid fuel discharged from the end falls on the upper side of the charged fuel, noise is generated.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 봄베내 충전연료량의 많고 적음에 상관 없이 봄베 내로 리턴되는 연료(액체상태 연료+기체상태 연료)에 의한 소음이 발생하지 않도록 된 엘피아이 차량 봄베의 연료 리턴소음 방지장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the ELPI is no longer generated by the fuel (liquid fuel + gaseous fuel) that is returned to the cylinder, regardless of the amount of fuel charged in the cylinder, regardless of the large or small amount It is an object of the present invention to provide a fuel return noise preventing device of a vehicle cylinder.

이하, 본 발명을 첨부된 예시도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명에 따른 연료 리턴소음 방지장치가 설치된 엘피아이 차량 봄베의 단면도 및 연료 리턴소음 방지장치의 사시도로서, 본 발명은 인젝터로부터 리턴되는 연료가 봄베(2)내로 유입되도록 봄베(2)의 몸체를 관통하여 연결된 리턴파이프(2)를 포함하는데 이 리턴파이프(2)의 하단부는 봄베(2)의 상벽면에 가까운 위치에 위치된다.3 is a cross-sectional view of the fuel tank and the fuel return noise prevention device is installed in accordance with the present invention is a perspective view of the fuel return noise prevention device, the present invention is a fuel (2) so that the fuel returned from the injector flows into the cylinder (2) It includes a return pipe (2) connected through the body of the lower end of the return pipe (2) is located at a position close to the upper wall surface of the cylinder (2).

상기 리턴파이프(2)의 하단에는 직육면체 박스 형상의 리저버(7)가 연결되는데, 상기 리턴파이프(2)는 리저버(7)의 상면을 통해 리저버(7)의 내부와 연통되어 있으며, 이 리저버(7)의 상면에는 다수의 배기공(7a)이 형성된다.A rectangular parallelepiped reservoir 7 is connected to a lower end of the return pipe 2, and the return pipe 2 communicates with the inside of the reservoir 7 through an upper surface of the reservoir 7. A plurality of exhaust holes 7a are formed on the upper surface of 7).

본 발명에 있어서, 상기 리저버(7)가 반드시 직육면체 박스 형상일 필요는 없으며, 단지 상부에 배기공들이 형성된 폐쇄용기(단, 상기 리턴파이프와 후술할 배출파이프와는 연통된다.)이면 모두 가능하다.In the present invention, the reservoir 7 does not necessarily have to have a rectangular parallelepiped box shape, but may be any closed container having exhaust holes formed therein (except for the return pipe and the discharge pipe to be described later). .

한편, 상기 리저버(7)의 하면에는 배출파이프(8)가 연결되는데, 이 배출파이프(8)는 상기 하면을 통해 리저버(7)의 내부와 연통되어 있음은 물론이며, 도시된 바와 같이 리저버(7)에 연결되는 위치는 상기 리턴파이프(2)의 연결위치와 서로 반대되도록 연결된다.Meanwhile, a discharge pipe 8 is connected to a lower surface of the reservoir 7, and the discharge pipe 8 communicates with the inside of the reservoir 7 through the lower surface, as shown in the drawing. The position connected to 7) is connected to be opposite to the connection position of the return pipe (2).

또한, 상기 배출파이프(8)의 하단은 봄베(1)의 바닥면에 근접한 위치까지 연장성형된다.In addition, the lower end of the discharge pipe 8 is extended to a position close to the bottom surface of the cylinder (1).

한편, 상기 배출파이프(8) 하단(배출구)의 위치는 봄베(1)에 연료가 10% 충전되었을 때의 연료 깊이 이내에 위치하도록 결정한다. 차량에서 연료 부족을 표시하는 경고등은 대개 연료탱크의 연료잔량이 총 용량의 10% 정도 남았을때부터 점등되도록 되어 있는바, 배출파이프(8)의 하단 위치를 상기와 같이 결정하면 연료가 부족하지 않은 대부분의 경우에 배출파이프(8)의 하단(배출구)을 항상 액상의 연료 속에 잠겨 있도록 할 수 있게 된다.On the other hand, the position of the lower end (discharge port) of the discharge pipe 8 is determined to be located within the fuel depth when the cylinder 1 is filled with 10% fuel. A warning light indicating a low fuel level in a vehicle is usually set to light up when the fuel tank remaining at about 10% of the total capacity remains. If the bottom position of the exhaust pipe 8 is determined as described above, there is no fuel shortage. In most cases it is possible to ensure that the bottom (outlet) of the exhaust pipe 8 is always submerged in liquid fuel.

상기 리저버(7) 하면의 위치는 봄베(1)의 연료 충전량 85%에 해당되는 연료 높이 이상으로 결정한다. 85%는 가스안전공사에서 법적으로 규제하고 있는 봄베의 충전 제한 용량으로서, 상기와 같이 리저버(7) 하면의 위치를 결정하면 봄베(1)내에 충전된 액상연료가 배출파이프(8)를 통하여 리저버(7)의 내측으로 역류해 들어오는 것을 방지할 수 있다.The position of the bottom surface of the reservoir 7 is determined to be equal to or higher than the fuel height corresponding to 85% of the fuel charge amount of the cylinder 1. 85% is the charge limiting capacity of the cylinder regulated by the Gas Safety Corporation. When the bottom of the reservoir 7 is determined as described above, the liquid fuel charged in the cylinder 1 is discharged through the discharge pipe 8. It is possible to prevent backflow into the inside of (7).

상기 리저버(7)의 용량(V)은 최대 리턴 연료량(V1) 이상이어야만 하는데, 대략 3배 이상(즉, V > 3V1)으로 설계하면 별 다른 문제가 발생하지 않는다.(여기서, 최대 리턴 연료량 V1 = 연료펌프 최대 용량 - 인젝터 최대 분사량)The capacity V of the reservoir 7 must be equal to or greater than the maximum return fuel amount V1, but if designed to be approximately three times or more (that is, V> 3 V1), no problem arises (wherein the maximum return fuel amount V1). = Maximum fuel pump capacity-injector maximum injection volume)

상기 리저버(7)의 상면에 형성되는 배기공(7a)들은 그 형상이나 수에 특별한 제한이 없으며, 리저버(7) 내의 기체가 외부로 자유로이 빠져나올 수 있도록 형성되면 충분하다.The exhaust holes 7a formed on the upper surface of the reservoir 7 are not particularly limited in shape or number, and may be formed so that the gas in the reservoir 7 can freely escape to the outside.

이하, 본 발명의 작용 및 효과를 설명한다.Hereinafter, the operation and effects of the present invention will be described.

인젝터에서 분사되지 않고 남은 연료는 상기 리턴파이프(2)를 통해 봄베(1)로 재유입된다.The fuel remaining without being injected from the injector is reintroduced into the cylinder 1 through the return pipe 2.

상기 리턴되는 엘피지 연료가 액체와 기체의 혼합상태임은 이미 설명하였다.It has already been described that the returned Elpgi fuel is a mixture of liquid and gas.

리턴파이프(2)에서 배출된 연료중 액체연료는 리저버(7)의 바닥으로 떨어지고 기체연료는 이 과정에서 액체연료와 분리되어 상기 배기공(7a)을 통해 봄베(1)의 내부 공간으로 확산된다.The liquid fuel in the fuel discharged from the return pipe 2 falls to the bottom of the reservoir 7 and the gaseous fuel is separated from the liquid fuel in this process and diffuses into the interior space of the cylinder 1 through the exhaust hole 7a. .

상기 리저버(7) 바닥의 액체연료는 상기 배출파이프(8)를 통해 봄베(1)에 충전된 액체상태의 연료 속으로 유입되어진다.Liquid fuel at the bottom of the reservoir 7 is introduced into the liquid fuel filled in the cylinder 1 through the discharge pipe 8.

즉, 리턴파이프(2)에서 배출된 액체와 기체의 혼합상태인 연료가 리저버(7)에서 액체연료와 기체연료가 분리된 후, 각각 기체연료는 봄베(1)내 기체에 혼합되고 액체연료는 기충전되어 있는 액체상태의 연료에 혼합되는 것이다.That is, after the liquid fuel and the gas fuel are separated from the return pipe 2 and the liquid fuel and the gas fuel are separated from the reservoir 7, the gaseous fuel is mixed with the gas in the cylinder 1 and the liquid fuel is It is mixed with the liquid fuel which is charged.

따라서, 기체연료가 액체상태의 연료 속에 배출되지 않음으로써 기포가 액체상태의 연료속에서 상방으로 부상하면서 생성되는 소음이 발생하지 않게 되고, 또한 액체연료가 봄베내에 충전되어 있는 액체상태의 연료 상면에 그 상방으로부터 떨어져 내리지 않게 됨으로써 액체가 액체에 떨어질 때 생성되는 소음도 발생하지 않게 된다.Therefore, the gaseous fuel is not discharged into the liquid fuel, so that the air bubbles rise upwards from the liquid fuel so that no noise is generated, and also the liquid fuel filled in the cylinder is placed on the upper surface of the liquid fuel. By not falling down from above, noise generated when the liquid falls into the liquid is also not generated.

이상 설명한 바와 같이 본 발명에 의하면, 과공급 연료가 봄베내로 리턴될 때 기체 및 액체상태의 연료가 각각 분리되어 기체상태의 연료는 공간으로 확산되고 액체상태의 연료는 충전되어 있는 액체연료의 내부로 유입됨으로써 기포 부상이나 액체 낙하에 의한 소음이 발생하지 않게 되는 효과가 있다.As described above, according to the present invention, when the over-supplied fuel is returned to the cylinder, the gaseous and liquid fuels are separated, and the gaseous fuel is diffused into the space, and the liquid fuel is filled into the liquid fuel. By the inflow, there is an effect that noise caused by bubble floating or liquid drop does not occur.
