More particularly, the present invention relates to an activation increaser for a catalytic converter for a vehicle, in which the temperature of the catalytic converter is increased by preheating the temperature of the catalytic converter using hot water heated during warming up of the vehicle. It is about.

도3은 종래기술에 따른 촉매 컨버터를 도시한 도면으로, 부호(1)는 촉매 컨버터를 지칭한다.Figure 3 shows a catalytic converter according to the prior art, in which reference numeral 1 designates a catalytic converter.

상기한 촉매 컨버터(1)의 기능상 종류로는 산화 촉매 컨버터와 삼원촉매 컨버터의 2종류가 있는데, 산화 촉매 컨버터는 촉매 펠리트라고 불리는 입상의 알루미나 표면에 촉매 작용을 하는 파라듐(Pd) 또는 파라듐+백금(Pt)의 귀금속을 극히 얇게 부착시킨 것으로 배기가수중의 CO와 HC를 무해한 CO₂와 H₂O로 만드는 기능이 있다.There are two kinds of functional types of the catalytic converter 1, which are an oxidation catalytic converter and a three-way catalytic converter. The oxidation catalytic converter has a palladium (Pd) or palladium which catalyzes the granular alumina surface called catalytic pellets. It is a very thin layer of precious metal of + Pt, which makes CO and HC in the exhaust water into harmless CO₂ and H₂O.

삼원 촉매 컨버터는 촉매 작용을 하는 귀금속 즉, 백금+로듐(Rh) 또는 백금+로듐+파라듐을 사용한 것으로 배기가스중의 CO, HC, NOx를 동시에 저감시키는 기능을 하므로 현재는 삼원촉매가 많이 사용되는 추세이다.The three-way catalytic converter uses noble metals, such as platinum + rhodium (Rh) or platinum + rhodium + palladium, to reduce CO, HC, and NOx in the exhaust gas at the same time.

그리고 상기 예열 제어장치(16)는 온수 순환장치(14)를 엔진의 시동전에 온수의 히팅과 촉매 컨버터(17)의 예열후 시동모타(20)의 작동이 이루어지게 이그니션 키이 스위치(22)에 연결되고 있다.The preheat control device 16 is connected to the ignition key switch 22 so that the hot water circulator 14 is heated before the engine is started and the starter motor 20 is operated after the preheating of the catalytic converter 17. It is becoming.

상기한 촉매 컨버터 활성화 증대장치(12)의 온수 순환장치(14)는 촉매 컨버터(17)의 외주면에 온수와 접촉하게 워터자켓(24)을 형성하고 있으며, 이 워터자켓(24)에 연결되는 공급관로(26)에 예열 제어장치(16)에 의해 제어되어 온수를 순환시키게 작동하는 순환팬(18)을 설치하고 있다.The hot water circulator 14 of the catalytic converter activation increasing device 12 forms a water jacket 24 on the outer circumferential surface of the catalytic converter 17 in contact with hot water, and is connected to the water jacket 24.

The return of hot water in the) is formed to be made by the discharge pipe (30).

한편, 촉매 컨버터 활성화 증대장치(12)의 예열 제어장치(16)는 이그니션 키이 스위치(22)와 연결되어 온 조작시 전원을 인가하게 되는 예열 스위치(32)를 설치하고 있고, 이 예열 스위치(32)에 연결되어 리저버 탱크(28)내의 온수를 히팅하는 예열 코일(34)을 내장 설치하고 있다.On the other hand, the preheating control device 16 of the catalytic converter activation increasing device 12 is provided with a preheating switch 32 for applying power during an operation connected with the ignition key switch 22, and the preheating switch 32 ) Is built in the preheating coil 34 for heating the hot water in the reservoir tank (28).

그리고 상기 리저버 탱크(28) 외측에 온수의 히팅정도를 감지하여 전원을 순환팬(18)에 통전시켜 작동시키는 제1온도 감지센서(36)를 설치하고 있다.In addition, a first temperature sensor 36 is installed outside the reservoir tank 28 to sense the heating degree of the hot water and energize and operate the power supply to the circulation fan 18.

또, 상기 순환팬(18)의 작동으로 워터자켓(24)내의 온수를 감지 소정 온도 이상일때 예열 스위치(32)를 단속하는 단속 스위치(38)를 오프시키면서 시동모타(20)의 구동이 이그니션 키이의 조작으로 가능하게 접속 작동하는 제2온도 감지센서(40)를 설치하고 있다.In addition, when the hot water in the water jacket 24 is detected by the operation of the circulation fan 18, when the intermittent switch 38 for controlling the preheating switch 32 is turned off when the temperature of the water jacket 24 is higher than a predetermined temperature, the ignition key 20 is driven. The second temperature sensor 40 is connected to be operated by the operation of.

상기한 제1,2 온도감지센서(36)(40)는 소정의 쳄버 하우징(42)에 변화하는 온도에 의해 열팽창하는 왁스(44)가 충진되어 있고, 이 왁스(44)의 일측에 팽창과 수축시 접속과 단속이 이루어지는 단자부(46)를 내장하고 있다.The first and second temperature sensors 36 and 40 are filled with a wax 44 thermally expanded by a predetermined temperature in a predetermined chamber housing 42, and one side of the wax 44 is expanded and The terminal part 46 which connects and interrupts at the time of contraction is incorporated.

상기 단자부(46)에는 시동모타(20)나 전원 회로와 연결되고 있다.The terminal portion 46 is connected to a starter motor 20 or a power supply circuit.

상기한 바와 같이 이루어지는 본 발명의 작용은 이그니션 키이를 온시키면 전원은 단속 스위치(38)를 통해 예열 스위치(32)를 온 조작시키며, 이에 따라 리저버 탱크(28)내의 예열 코일(34)을 가열시킨다.When the ignition key is turned on, the power supply turns on the preheating switch 32 through the intermittent switch 38, thereby heating the preheating coil 34 in the reservoir tank 28. .

상기한 예열 코일(34)의 가열에 의해 온수의 히팅이 이루어지면 리저버 탱크 (28) 외부의 제1온도 감지센서(36)에 전열되어 왁스(44)의 열팽창이 이루어지면서 고 단자부(46)의 접속이 이루어지게 된다.When heating of the hot water is performed by the heating of the preheating coil 34, heat is transferred to the first temperature sensor 36 outside the reservoir tank 28 so that the thermal expansion of the wax 44 is performed. The connection is made.

상기한 제1온도 감지센서(36)의 접속이 이루어짐에 따라 순환팬(18)이 작동하여 공급관로(26)를 통해 히팅된 온수를 워터자켓(24)에 공급하게 되고, 배출관로(30)를 통해 리저버탱크(28)로 재순환이 이루어진다.As the first temperature sensor 36 is connected, the circulation fan 18 operates to supply hot water heated through the supply pipe 26 to the water jacket 24, and the discharge pipe path 30. Through the recirculation to the reservoir tank 28 is made.

따라서 상기한 워터자켓(24)내를 히팅된 온수가 순환하게 되므로서 촉매 컨버터(17)는 온수에 의해 예열이 이루어지게 되고, 제2온도 감지센서(40)는 촉매 컨버터(17)를 예열을 감지하게 된다.Therefore, the hot water heated in the water jacket 24 is circulated so that the catalytic converter 17 is preheated by the hot water, and the second temperature sensor 40 preheats the catalytic converter 17.

상기한 단속 스위치(38)의 전원 단속으로 예열 스위치(32)도 전원을 차단하게 되어 예열 코일(34)의 발열을 멈추게 한다.The preheat switch 32 also cuts off the power by interrupting the power of the intermittent switch 38 to stop the heating of the preheating coil 34.

상기한 예열 코일(34)의 가열 중단으로 리저버 탱크(28)내 온수는 온도가 낮아지게 되는데, 이를 제1온도 감지센서(36)가 감지하므로서 왁스(44)는 수축이 이루어져 단자부(46)의 접속을 해제시킨다.As the preheating coil 34 stops heating, the hot water in the reservoir tank 28 is lowered in temperature. As the first temperature sensor 36 detects this, the wax 44 contracts to form the terminal 46. Disconnect the connection.

따라서 상기 제1온도 감지센서(36)의 전원 차단으로 순환팬(18)에 인가되고 있던 전원도 단속되어 순환팬(18)의 작동을 정지시킨다.Accordingly, the power applied to the circulation fan 18 is also interrupted by the power cutoff of the first temperature sensor 36 to stop the operation of the circulation fan 18.

그리고 나서 운전자가 이그니션 키이 스위치(22)를 조작 스타트 위치에 놓음으로서 차량의 시동은 이루어지고 시동에 따른 워밍업시 배출되는 배기가스는 예열된 촉매 컨버터(17)에서 산화와 환원 작용의 증대가 이루어지게 된다.Then, the driver starts the vehicle by starting the ignition key switch 22 in the operation start position, and the exhaust gas discharged during warm-up according to the start-up is increased in the preheated catalytic converter 17 to increase the oxidation and reducing action. do.

상기한 본 발명은 시동전 이그니션 키이 스위치를 온 위치시켜 둠으로서 촉매 컨버터를 예열시켜 워밍업시 배출되는 배기가스의 정화 효율을 용이하게 증대시킬 수 있는 발명이다.The present invention described above is an invention in which the ignition key switch is turned on before starting, thereby preheating the catalytic converter to easily increase the purification efficiency of the exhaust gas discharged during warming up.

따라서 차량의 워밍업시에도 촉매 컨버터의 배기가스 정화 효율이 향상되므로서 유해 배출가스의 대기중 방출을 저감시키게 된다.Therefore, the exhaust gas purification efficiency of the catalytic converter is improved even when the vehicle is warmed up, thereby reducing the emission of harmful emissions into the atmosphere.
