이하, 본 고안의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[실시예]EXAMPLE
도면은 본 고안에 따른 바람직한 실시예의 촉매 변환기의 가열장치를 나타낸다. 도시된 바와 같이, 엔진(1)으로부터 발생하는 배기가스를 시동초기에 승온시키기 위한 마이크로파를 발생시키는 마이크로파 발생장치(2)가 배터리(3)에 연결되어 있다. 메니폴드(4)와 머플러(5) 사이에는 촉매변환기(6)이 설치되어 있으며, 촉매 변환기(6)는 메인 촉매(61)와 메인 촉매(61)의 전방에 배열된 라이트-오프 촉매(62)로 이루어진다. 라이트-오프 촉매(62)의 전방, 즉 메이폴드측에는 본 고안의 중요한 구성요소인 마이크로파 발생장치(2)로부터 발생한 마이크로파를 받아들이는 마이크로파 반사체(7)가 배열되어 있다. 이 마이크로파 반사체(7)의 전방, 즉 메니폴드 폴드측에는 마이크로파 가열촉매(8)가 놓여있다. 마이크로파 가열 촉매는 마이크로파를 흡수하여 발열할 수 있는 물질이 코팅되어 있다.The figure shows a heating device of a catalytic converter of a preferred embodiment according to the present invention. As shown, a microwave generator 2 for generating microwaves for warming up the exhaust gas generated from the engine 1 at the start-up is connected to the battery 3. A catalytic converter 6 is provided between the manifold 4 and the muffler 5, and the catalytic converter 6 is a light-off catalyst 62 arranged in front of the main catalyst 61 and the main catalyst 61. Is made of. In front of the light-off catalyst 62, i.e., the mayfold side, a microwave reflector 7 which receives microwaves generated from the microwave generator 2, which is an important component of the present invention, is arranged. A microwave heating catalyst 8 is placed in front of the microwave reflector 7, that is, at the manifold fold side. Microwave heating catalysts are coated with a material that can absorb microwaves and generate heat.
이러한 본 고안의 배기가스의 가열시스템에 의한 작용을 설명하면, 시동전에 배터리(3)에 연결된 마이크로파 발생장치(2)에서 마이크로파를 발생시킨다. 발생된 마이크로파는 촉매변화기(6)의 전방에 배열된 마이크로파 반사체(7)로 보내어진다. 마이크로파 반사체(7)에 보내어진 마이크로파는 마이크로파 가열 촉매(8)에 조사된다. 이때, 마이크로파 가열촉매에는 마이크로파를 흡수하여 발열할 수 있는 물질이 코팅되어 있어서, 마이크로파 가열 촉매(8)는 가열된다. 따라서, 시동초기에 배기가스를 마이크로파에 의한 가열을 통하여 신속히 300℃부근으로 상승된다. 시동과 함께 배출되는 배기가스는 마이크로파 가열 촉매(8)를 통과하면서, 승온되어 라이트-오프 촉매(62) 및 메인 초매(61)를 지나면서 정화된다.Referring to the action by the heating system of the exhaust gas of the present invention, microwaves are generated in the microwave generator 2 connected to the battery 3 before starting. The generated microwaves are sent to the microwave reflector 7 arranged in front of the catalytic converter 6. The microwaves sent to the microwave reflector 7 are irradiated to the microwave heating catalyst 8. At this time, the microwave heating catalyst is coated with a material capable of absorbing microwaves and generating heat, so that the microwave heating catalyst 8 is heated. Therefore, the exhaust gas is rapidly raised to around 300 ° C through heating by microwaves at the beginning of the start-up. The exhaust gas discharged with the start-up is heated up while passing through the microwave heating catalyst 8, and purified while passing through the light-off catalyst 62 and the main choke 61.
본 고안은 실시예에 의하면, 촉매변환기의 메인 촉매 전방의 배기가스의 온도를 상승시키기 위하여, 마이크로파 발생장치로부터 발생된 마이크로파가 마이크로파 반사체에 보내어져 마이크로파 가열 촉매를 가열시킴으로써, 시동시의 배기가스가 승온된 마이크로파 가열 촉매를 통과하면서, 승온되어 라이트-오프 촉매 및 메인 촉매를 지나면서 정화되게 된다.According to an embodiment of the present invention, in order to raise the temperature of the exhaust gas in front of the main catalyst of the catalytic converter, the microwave generated from the microwave generator is sent to the microwave reflector to heat the microwave heating catalyst, so that the exhaust gas at start-up While passing through the heated microwave heating catalyst, the temperature is raised to purge through the light-off catalyst and the main catalyst.
