Description
본 고안은 배기가스를 회수하여 흡기측에 공급하여 재연소시키는 배기가스 회수 연소장치에 관한 것이다.The present invention relates to an exhaust gas recovery combustion apparatus for recovering exhaust gas and supplying it to the intake side for reburning.
종래 배기가스의 공해 방출량을 감소시키기 위해서는 도 2에 도시하는 것과같이 배기매니폴드(2)로부터 흡기매니폴드(3)측의 서지탱크(4)에 접속하는 리턴파이프(5)를 설치한 후 솔레노이드밸브(6)의 작동을 통해 리턴파이프(5)를 차단하거나 또는 개방하므로써 배기되는 배기가스의 일부를 회수하여 흡기에 혼합시켜 연소를 행하고 있다.In order to reduce the emission amount of the conventional exhaust gas, as shown in FIG. 2, after the return pipe 5 is connected to the surge tank 4 on the intake manifold 3 side from the exhaust manifold 2, the solenoid is provided. By operating the valve 6, the return pipe 5 is blocked or opened to recover a part of the exhaust gas that is exhausted, mixed with intake air, and combusted.
그러나 상기와 같은 구조는 외기가 저온 다습할 경우 서지탱크 내부의 수분이 응집되어 결빙되는 것을 방지코자 하는 목적에서 솔레노이드밸브(6)의 개폐제어를 행하는 것이어서 엔진의 운전조건에 맞추어 적정량의 배기가스를 리턴 공급할 수는 없기 때문에 배기가스 배출량을 어느정도 이상 감소시키는 데에는 한계가 있는 것이었다.However, the above structure is to control the opening and closing of the solenoid valve 6 in order to prevent the moisture inside the surge tank from condensing and freezing when the outside air is low temperature and high humidity. There was a limit to reducing emissions more than a certain amount because it could not be returned.
이에 본 고안은 상기한 문제점을 해소하기 위해 제안된 것으로서 그의 목적으로 하는바는 엔진의 운행 상태에 따라 개별적으로 배기가스의 리턴되는 양을 조절하므로써 배기가스 공해 배출량을 효과적으로 감소시킬 수 있는 구조의 배기가스 회수 연소장치를 제공하는 데 있다.Therefore, the present invention has been proposed to solve the above problems, and its purpose is to exhaust the exhaust gas pollution by controlling the return amount of the exhaust gas individually according to the operating state of the engine. A gas recovery combustion apparatus is provided.

이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 고안에 의한 배기가스 회수 연소장치의 일실시예를 나타내는 도면으로 도면중 부호 1은 엔진이며 부호 2는 엔진으로부터 배출되는 배기가스의 통로인 배기매니폴드이다.1 is a view showing an embodiment of an exhaust gas recovery combustion apparatus according to the present invention, in which 1 is an engine and 2 is an exhaust manifold which is a passage of exhaust gas discharged from an engine.
상기 배기매니폴드(2)와 흡기매니폴드(3)측의 서지탱크(4)와는 리턴파이프(5)가 접속되어 있어 배기되는 높은 압의 배기가스의 일부가 흡기측의 부압에 의해 상기 리턴파이프(5)를 통해 서지탱크(4)에 공급되어지게 된다.The return pipe 5 is connected to the exhaust manifold 2 and the surge tank 4 on the intake manifold 3 side, so that a part of the high pressure exhaust gas exhausted is caused by the negative pressure on the intake side. It is supplied to the surge tank (4) through (5).
상기 리턴파이프(5)의 도중에는 배기가스의 회수공급 여부를 1차적으로 단속하기 위한 솔레노이드밸브(6)가 마련되어 있으며 서지탱크(4)와의 접속단부에는 배기가스를 분사하여 방출하는 분사기(7)가 장착되어 있다.A solenoid valve 6 is provided in the middle of the return pipe 5 to control whether or not the exhaust gas is supplied and the injector 7 for injecting and discharging the exhaust gas is connected to the surge tank 4. It is installed.
상기 분사기(7)는 전자제어장치(8)에 의해 분사시간이 결정되며 상기 전자제어장치(8)는 운전석의 엔진 RPM 표시기(9, 크러스터)로부터의 엔진운행 정보를 받아서 엔진회전수에 비례하도록 상기 분사기(7)의 분사시간을 제어한다.The injection time of the injector 7 is determined by the electronic control device 8 and the electronic control device 8 receives engine operation information from the engine RPM indicator 9 (cluster) of the driver's seat so as to be proportional to the engine speed. The injection time of the injector 7 is controlled.
이상과 같은 본원 고안의 배기가스 회수 연소장치에 의하면 배기매니폴드와 서지탱크 사이를 연결하는 리턴파이프에 외기의 조건에 따라 배기가스를 단속하는 솔레노이드밸브와 더불어 엔진회전수 정보에 따라 배기가스 흡입량을 조정하기 위한 분사기가 마련되므로써 엔진회전수에 비례하여 도입되는 배기가스량을 공급하게 되어 배기가스 공해 발생량을 효과적으로 감소시키게 된다.According to the exhaust gas recovery combustion apparatus of the present invention as described above, in addition to the solenoid valve for controlling the exhaust gas in accordance with the condition of the outside air in the return pipe connecting the exhaust manifold and the surge tank, the exhaust gas intake amount is adjusted according to the engine speed information. Since the injector for adjustment is provided, the amount of exhaust gas introduced in proportion to the engine speed is supplied to effectively reduce the amount of emission of the exhaust gas.
