본 고안은 자동차용 내연기관의 희박혼합기를 재기화시키는 장치에 관한 것으로 그 목적은 희박혼합기 연소방식에 이론적 근거를 두고 연료의 소비량을 절감함과 아울러 연소효율의 향상을 도모하여 유해배기가스의 발생원인을 제거하는 장치를 제공하는데 있다.The present invention relates to a device for regasifying a lean mixer of an internal combustion engine for automobiles. The purpose of the present invention is to reduce the consumption of fuel and improve combustion efficiency based on the lean mixer combustion method. It is to provide a device for removing the.
공지의 희박혼합기 조장방식에 있어서, 몇가지 예를 든다면 기화기에 공급하는 1차공기를 처음부터 히이터로 예열하는 방식이 있고, 다른 예로는 기화기와 엔진의 흡입구 사이에 별도의 공기 공급장치를 개입시켜서 그 장치를 통하여 외부에서 예열한 2차 공기를 공급하거나, 그 공급장치에 회전익 또는 고정익등을 설치하여 기. 액의 혼합을 조장케하는 방식이 고안되고 있다.In the known lean-mixer system, some examples include a method of preheating the primary air supplied to the carburetor with a heater from the beginning, and another example is through a separate air supply device between the carburetor and the engine inlet. Supplying secondary air preheated from the outside through the device, or installing rotary blades or fixed blades to the supply device; A method of encouraging the mixing of liquids has been devised.
그러나 상기한 바와 같은 공지의 희박혼합기 조장방식에 있어서는 그 대부분 예열한 2차 공기의 공급이나 기. 액의 혼합만을 목적에 두었을 뿐 차종의 배기량에 따라 가솔린의 흡입량을 도외시한 경향 때문에 혼합비의 바란스가 효율적으로 이루어지지 못하고, 녹킹과 불완전 연소를 초래하여 유해배기가스를 방출하였다.However, in the well-known lean-mixer system as described above, most of the preheated secondary air is supplied. Only the purpose of mixing the liquids, but the tendency of neglecting the intake of gasoline according to the exhaust volume of the vehicle, the balance of the mixing ratio could not be achieved efficiently, leading to knocking and incomplete combustion to release the harmful exhaust gas.
본 고안은 상기와 같은 문제점을 해소하고저 기화기와 엔진의 흡입구 사이에 히이터를 설치하는 것에 있어서, 그 히이터를 2차의 회로로 구성하고, 그 2차 회로를 제어기에 접속시켜서 온도 감지기에 의하여 1차 회로나 1차 회로에 선택적으로 전류가 흐르게 하여 연소조건에 따라 소정된 온도로 발열되게 하며, 기화기내에 착설된 통상의 메인제트에 있어서는 차종의 배기량에 따라 그 내경을 조정하면 적정량의 가솔린이 공급된다. 따라서 희박화된 혼합기가 상기한 히이터에 의하여 재기화되도록 촉진하므로서 연료의 절약과 차종의 배기량에 따라 연소효율을 만족하게 향상시킬 수 있는 장치를 제공코저 하는 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves the above problems, and in installing a heater between the low vaporizer and the engine inlet, the heater is constituted by a secondary circuit, and the secondary circuit is connected to a controller to provide a temperature sensor. The current flows selectively to the primary circuit and the primary circuit, and generates heat at a predetermined temperature according to the combustion conditions.In a normal main jet installed in the carburetor, an appropriate amount of gasoline is supplied when the inner diameter is adjusted according to the exhaust volume of the vehicle model. do. Accordingly, the present invention provides a device capable of satisfactorily improving the combustion efficiency according to fuel consumption and vehicle displacement by facilitating a thinner mixer to be regasified by the heater described above. .
제 1 도의 부호 (가)는 본 고안의 일요부인 가열기인데, 내열재로 형성된 틀(1)의 양벽에 상대적으로 상한통공(2)을 등간격으로 뚫어서 서로 어긋나게 하고, 각 통공(2)에는 단자(3)를 각각 삽설하여 서로 상대하는 단자 사이에 코일선(4)의 양단을 삽감하고, 각 단자(3)의 상층 외단부와 하층 외단부를 접속편(5)으로 서로 엇갈리게 연접하여 전체의 코일선(4)이 일련체가 되게하고, 일측의 최종단자(3a)에는 온도감지기(6)를 부착한다. 그리고 각 단자(3)중에서 인출한 1차회선(7)과 2차회선(8) 및 온도감지기(6)에서의 회선(9)을 통상의 제어기(10)(제 4 도 참조)의 도시하지 않은 릴레이 접점에 각각 접속한다. 또한 부차적으로 제 5 도에 도시한 기화기 (나)의 후로우트실에 착설한 메인노즐(11)은 각 차종의 배기량에 준하여 그 내경(D)을 표준치수 보다 4/100-10/100mm 작은 치수의 것으로 대체한다. 미설명부호 12는 점화코일이다.Reference numeral (a) of Fig. 1 is a heater which is an essential part of the present invention. The upper limit holes (2) are drilled at equal intervals on both walls of the frame (1) formed of a heat-resistant material so as to be offset from each other, and each terminal (2) has a terminal. (3) are inserted respectively, and both ends of the coil wire 4 are inserted between the terminals facing each other, and the upper and lower outer ends of each terminal 3 are connected to each other by connecting pieces 5 alternately. The coil wire 4 is a series body, and the temperature sensor 6 is attached to the final terminal 3a on one side. The primary line 7 and secondary line 8 drawn out of each terminal 3 and the line 9 of the temperature sensor 6 are not shown in the conventional controller 10 (see FIG. 4). Connect to each relay contact. In addition, the main nozzle 11 installed in the float chamber of the carburetor (b) shown in FIG. 5 has a diameter of 4 / 100-10 / 100 mm smaller than the standard dimension based on the displacement of each vehicle model. Replace with Reference numeral 12 is an ignition coil.
상기와 같이 구성된 본 고안은 가열기(가)를 제 5 도와 같이 기화기(나)와 엔진의 흡입구(다) 사이에 착설하고 후로우트실의 연료면(L)을 종래보다 3-5mm 낮은 수준으로 유지한다.According to the present invention configured as described above, the heater (a) is installed between the carburetor (b) and the intake port (c) of the engine as the fifth degree, and the fuel surface (L) of the float chamber is maintained at a level of 3-5 mm lower than the conventional one. do.
이와같이 하면 기화기(나)의 메인제트(11)를 통하는 연료의 분출량이 감소되고, 공기와 연료의 혼합비는 중량비로 20 : 1 정도가 된다. 그리고 도시하지 않은 점화스위치를 넣으면 제어기(10)내의 릴레이 스위치에 의하여 코일(4)의 1차회로에 축전지의 전류가 흘러서 그 코일이 발열하여 200℃의 온도를 유지하게 된다. 이때에 혼합기는 각 코일이 상기한 바와 같이 발열된 상태에 있고 또 상하층으로 서로 엇갈리게 착설되고 있으므로 각 코일 사이를 지그재그 상태로 통과하여 100℃정도로 가열되며 기관의 정상운전 온도에 달하면, 온도감지기(6)가 작동하에 제어기(10)의 2차 릴레이 스위치가 접속되므로 전체코일에 전류가 흐르게 되어 혼합기는 점화 가능한 영역의 것으로 재기화(팽창)된다.In this way, the ejection amount of the fuel through the main jet 11 of the vaporizer | carburetor (b) is reduced, and the mixing ratio of air and fuel is about 20: 1 by weight ratio. When the ignition switch (not shown) is inserted, the current of the storage battery flows in the primary circuit of the coil 4 by the relay switch in the controller 10, and the coil generates heat to maintain a temperature of 200 ° C. At this time, since the mixers are in a heated state as described above and are installed alternately in the upper and lower layers, the mixer passes through each coil in a zigzag state and is heated to about 100 ° C. and reaches a normal operating temperature of the engine. Under operation 6), the secondary relay switch of the controller 10 is connected so that a current flows through the entire coil so that the mixer is regasified (expanded) to that of the ignitable region.
따라서 연료 소비량이 감소되는 반면에 상기한 바와 같은 재기화 방식에 의하여 완전에 가까운 연소효율을 기하게 되어 유해 배기가스의 발생원인을 십분개선할 수 있는 효과를 발휘하는 것이다.Therefore, while the fuel consumption is reduced, by the regasification method as described above to achieve near-perfect combustion efficiency, it is possible to exert an effect that can improve the cause of generation of harmful exhaust gas.
