본 고안은 내연기관의 흡기 예열장치에 관한 것이다.The present invention relates to an intake preheater of an internal combustion engine.
내연기관의 연소에 필요한 공기에 에어크리너에서 여과된 대기중의 공기가 연소실에 고급되는 것이므로 대기의 온도가 낮은 계절에 대기중의 공기가 그대로 연소실에 공급되면 제3도에 도시한 바와 같이 흡기온도가 적정일 경우에 비하여 그 연료소비율이 급중하게 될 뿐 아니라 제4도에 도시한 바와 같이 탄화수소 및 일산화탄소의 배출량이 많아져서 공해요인이 되고 있으므로 상기한 연료소비율의 급증과 탄화수소 및 일산화탄소의 배출량을 줄이기 위하여 대기의 온도가 낮을 때에 연소실에 공급되는 흡기를 예열하고 있으며 그 열원으로서 내연기관에서 배출되는 배기가스, 전열 등을 이용하고 있다.Since the air in the air filtered by the air cleaner is advanced to the combustion chamber for the air required for the combustion of the internal combustion engine, when the air in the air is supplied to the combustion chamber as it is during the season of low temperature, the intake temperature is as shown in FIG. Is not only rapidly increasing the fuel consumption rate, but also increases the emissions of hydrocarbons and carbon monoxide as shown in FIG. For this purpose, the intake air supplied to the combustion chamber is preheated when the temperature of the air is low, and exhaust gas, heat transfer, etc. discharged from the internal combustion engine are used as the heat source.
그러나 배기가스를 열원으로 이용하는 경우에는 일본국 실용신안출원공개 평 1-158548에 개시된 바와 같이 배기관의 외주에 흡기가열기를 설치한 것이므로 흡기가열기를 배기관에 설치하기가 어려운 결점이 있는 것이다.However, in the case of using the exhaust gas as a heat source, the intake air heater is installed on the outer circumference of the exhaust pipe as disclosed in Japanese Utility Model Application Publication No. Hei 1-158548, which makes it difficult to install the intake air heater in the exhaust pipe.
본 고안은 상기한 결점을 시정하여 케이스를 에어크리너와 연료분사장치 사이의 흡기관에 간단히 부착함과 동시에 가열관도 배기관에 쉽게 연결할 수 있고, 그 구성이 간단한 내연기관의 흡기 예열장치를 제공하는 것을 목적으로 한다.The present invention is to provide an intake preheating device of an internal combustion engine that is easy to connect the heating tube to the exhaust pipe at the same time by simply attaching the case to the intake pipe between the air cleaner and the fuel injection device by correcting the above drawbacks. The purpose.
본 고안은 상기한 목적을 달성하기 위하여 유입관과 배출관이 부착된 케이스에 하방에 유통공을 뚫은 제1및 제2격판을 설치함과 동시에 그 중간에 케이스의 내벽 상부와의 사이에 유통부가 형성되게 중간격판을 설치하여 우회통로를 형성하고, 제 1및 제2격판과 중간격판의 상방에 구멍을 뚫어 가열관을 설치한 것이다.In order to achieve the above object, the present invention provides a distribution part between the upper part of the inner wall of the case and the first and second plate having a distribution hole drilled downward in the case where the inlet pipe and the discharge pipe are attached. By installing the intermediate plate to form a bypass passage, the heating pipe is installed by drilling a hole above the first and second plate and the intermediate plate.
이하 실시예 도면에 의하여 설명한다.A description with reference to the following drawings.
본 고안은 제1도 및 제2도에 도시한 바와 같이 도시하지 않은 에어크리너와 연료분사장치 사이의 흡기관에 설치되며 유입관(1)과 배출관(2)이 부착된 케이스(3)의 좌우에 하방에 유통공(4)(4')을 뚫은 제 1 및 제 2 격판(5)(6)을 설치하고 제 1 격판(5)과 제2격판(6)의 중간에 케이스(3)의 내벽 상부와의 사이에 유통부(7)가 형성되게 중간격판(8)을 설치하여서 우회통로(9)(9')를 형성하여 흡기가 우회할 수 있게 하며, 제1및 제2격판(5)(6)과 중간격판(8)의 상방에 구멍(10)(11)을 뚫어 도시하지 많은 배기관에서 분기되는 U자형의 가열관(12)을 설치하여서 된 것이며, 상기한 실시예에서 격판(5)(6)(8)과 가열관(12)은 열전도율과 열흡수율이 양호한 스테인레스 등으로 만든다.The present invention is installed in the intake pipe between the air cleaner and the fuel injection device (not shown) as shown in FIGS. 1 and 2, and the left and right sides of the case 3 having the inlet pipe 1 and the discharge pipe 2 attached thereto. The first and second diaphragms 5 and 6, which are drilled through the distribution holes 4 and 4 ', are installed in the lower portion of the case 3 in the middle of the first diaphragm 5 and the second diaphragm 6. By installing the intermediate plate 8 so that the distribution part 7 is formed between the upper part of the inner wall, the bypass passages 9 and 9 'are formed to allow the intake air to bypass and the first and second plate 5 (6) and the U-shaped heating tube (12) branched from many exhaust pipes (not shown) by drilling holes (10) and (11) above the intermediate plate (8). 5) (6) (8) and the heating tube 12 are made of stainless steel having good thermal conductivity and heat absorption rate.
이상과 같은 본 고안은 에어크리너에서 여과된 흡기가 유입공(1)으로 유입되어 제1격판(5)의 하방에 뚫은 유통공(4)을 통과한 후 중간격판(8)에 부딪쳐 우회통로(9)에서 상방으로 우회하면서 중간 격판(8)과 케이스(3)의 내벽사이에 형성되는 유통부(7)를 거친 다음 우회통로(9`)로 하강하여 제2격판(6)의 하방에 뚫은 유통공(4`)을 통하여 배출관(2)으로 배출되어 에어크리너와 연료분사장치 사이의 흡기관에 공급되며, 흡기가 케이스(3)를 통과할 때 내연기관의 배기관에서 분기되어 U자형의 가열관(11)에 고급되는 배기가스에 의하여 예열되는 것이다. 이때 격판(5)(6)(8)은 흡열핀의 기능도 수행하므로 급기예열 효과가 양호하게 되는 것이다.The present invention as described above, the intake air filtered from the air cleaner flows into the inlet hole (1) and passes through the distribution hole (4) drilled below the first plate (5) hit the intermediate plate (8) bypass passage ( 9) while bypassing upwards, passes through a distribution section 7 formed between the middle diaphragm 8 and the inner wall of the case 3, and then descends into the bypass passage 9`, which is drilled below the second partition 6 It is discharged to the discharge pipe (2) through the distribution hole (4`) and supplied to the intake pipe between the air cleaner and the fuel injection device, and branched from the exhaust pipe of the internal combustion engine when the intake air passes through the case (3), U-shaped heating It is preheated by the exhaust gas advanced to the pipe 11. At this time, the diaphragm 5, 6, 8 also performs the function of the heat absorbing fin, so that the air supply preheating effect is good.
이상과 같이 본 고안은 케이스에 제1및 제2격판과 중간격판을 설치하여 흡기를 우회시키면서 배기가스의 배기열이 유통되는 가열관에서 예열토록 되어 있으므로 그 구성이 간단하면서 흡기예열효과가 양호하고, 가열관은 도관을 연장하여 배기관에 구멍만을 뚫어서 간단하게 설치할 수 있는 등의 효과가 있는 것이다.As described above, the present invention is provided with the first and second plates and the intermediate plate in the case so as to bypass the intake and preheat in the heating tube through which the exhaust heat of the exhaust gas flows. The heating tube has an effect such as to simply install a hole by extending only the conduit to the exhaust pipe.
