본 발명은 차량의 에미션 제어장치에 관한 것으로, 더 상세하게는 냉간 상태의 초기 시동 온 직후 분사된 시동 연료량이 흡기 포트에서 최대한 증발된 이후에 연소실로 유입되도록 하는 차량의 에미션 제어장치에 관한 것이다. The present invention relates to an emission control apparatus for a vehicle, and more particularly, to an emission control apparatus for a vehicle such that the amount of starting fuel injected immediately after initial start-up in a cold state is introduced into the combustion chamber after the maximum evaporation from the intake port. will be.

일반적으로, SULEV(Super Ultra Emission Vehicle) 차량의 EM(Emission)은 미국의 배기가스 규제인 LEV-Ⅱ 규제(0.55g/mile-120K mile 보증)에 대비하여 NMOG(Non Methane Organic Gas)의 기준(0.01g/mile-150K mile 보증)으로 강화되었으며, 냉간시 발생되는 불완전 연소에 대하여 안정적인 에미션 저감이 요구되고 있다.In general, the emission of SULEV (Super Ultra Emission Vehicle) vehicles is based on the standards of Non Methane Organic Gas (NMOG) against the LEV-II regulation (0.55 g / mile-120 K mile guarantee). 0.01g / mile-150K mile guarantee), and stable emission reduction is required for incomplete combustion generated during cold.

그러나, 차량에 따라 연료계통이나 인젝터 및 엔진 등의 하드웨어적인 편차 및 차량의 내구 진행에 따라 불완전 연소에 의한 에미션 증가폭은 기존 LEV-Ⅱ 규제에 대비하여 큰 영향으로 나타난다.However, the increase in emissions due to incomplete combustion due to hardware deviations of fuel systems, injectors, and engines, and the durability of the vehicle may be significant in comparison with the existing LEV-II regulations.

이를 방지하지 위해 냉간 상태에서 초기 시동에 따른 초기 아이들 구간에서의 공연비를 최대한 희박(Lean)하게 불완전 연소에 의한 에미션을 줄이고, 촉매의 활성화시간을 단축시켜 에미션 저감을 극대화하여야 하나, 차량의 열화에 따른 인젝터의 분사각도 변화 및 분사된 연료의 침전물에 의해 흡기 포트내의 증발특성을 변화시켜 웰 웨이팅(Wall Wetting)량을 증가시키며 이에 따라 불완전 연소에 따른 에미션 악화시키는 문제점이 발생된다.In order to prevent this, the air-fuel ratio in the initial idle section according to the initial start-up in the cold state should be leaned as much as possible to reduce the emission due to incomplete combustion, and the activation time of the catalyst should be shortened to maximize the emission reduction. By changing the injection angle of the injector due to deterioration and the deposition of the injected fuel by changing the evaporation characteristics in the intake port to increase the amount of well wetting (Wall Wetting), thereby causing a problem of worsening the emission due to incomplete combustion.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로, 그 목적은 냉간 상태에서의 초기 시동 직후 리니어 산소센서의 공연비 값에 따라 분사시간(EOIT : End Of Injection Time)을 제어하여 분사된 연료가 흡기 포트내에서 증발할 수 있는 시간을 연장시켜 에미션의 안정화를 제공하는 것이다.The present invention has been invented to solve the above problems, and its object is to control the injection time (EOIT: End Of Injection Time) according to the air-fuel ratio value of the linear oxygen sensor immediately after the initial start in the cold state. The evaporation time in the pot is extended to provide stabilization of the emission.

즉, 냉간 시동 직후 일정기간 동안의 아이들 구간에서 측정된 공연비가 일정기준치를 초과하면 초과된 양만큼 난기 후 상태의 분사시간에 대비하여 일정비율로 최대값까지 감소시켜 분사된 연료량이 흡기 포트에서 최대한 증발된 후 연소실로 유입되도록 하는 것이다.That is, if the air-fuel ratio measured in the idle section for a certain period immediately after cold start exceeds a certain standard value, the amount of fuel injected is reduced to the maximum value at a constant ratio in preparation for the injection time after warming up by the amount exceeded. After the evaporation is to enter the combustion chamber.

상기한 목적을 실현하기 위한 본 발명의 특징에 따르면, 엔진 회전수를 검출하는 RPM센서와 냉각수의 온도를 검출하는 수온센서 및 배기 매니폴더에 장착되어 공연비를 검출하는 산소센서를 포함하는 차량의 에미션 제어장치에 있어서,
냉간 시동 직후 아이들 구간에서 산소센서의 공연비가 일정 기준치를 초과하면 초과된 양에 따라 난기 후 상태의 분사시간에 대비하여 분사시간을 일정비율로 감소시켜 분사된 연료가 흡기 포트에서 증발되는 시간을 연장시켜 희박 공연비로 유도시키는 제어부를 포함하는 차량의 에미션 제어장치가 제공된다.According to a feature of the present invention for realizing the above object, an Emmy of a vehicle comprising an RPM sensor for detecting the engine speed, a water temperature sensor for detecting the temperature of the coolant and an oxygen sensor mounted in the exhaust manifold for detecting the air-fuel ratio In the Sean control unit,

전술한 구성에 의하여 본 발명은 차량별 분사각도의 편차, 연료성상 변화 및 엔진의 내구 등에 대하여 안정된 에미션을 제공하는 효과를 기대할 수 있다.By the above-described configuration, the present invention can be expected to provide an effect of providing a stable emission against the variation in the injection angle of each vehicle, the change in fuel properties, the durability of the engine and the like.

아래에서는 첨부한 도면을 참고로 하여 본 발명의 실시예에 대하여 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 상세히 설명한다. DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

본 발명은 여러 가지 상이한 형태로 구현될 수 있으므로 여기에서 설명하는 실시예에 한정되지 않으며, 도면에서 본 발명을 명확하게 설명하기 위해서 설명과 관계없는 부분은 생략하였다.Since the present invention can be implemented in various different forms, the present invention is not limited to the exemplary embodiments described herein, and parts not related to the description are omitted in the drawings in order to clearly describe the present invention.

도 1은 본 발명의 실시예에 따른 차량의 에미션 제어장치를 개략적으로 도시한 도면이다.1 is a view schematically showing an emission control apparatus for a vehicle according to an embodiment of the present invention.

본 발명은 RPM센서(10)와 수온센서(20), 산소센서(30), 제어부(40) 및 분사장치(50)를 포함한다.The present invention includes an RPM sensor 10, water temperature sensor 20, oxygen sensor 30, the control unit 40 and the injection device (50).

RPM센서(10)는 크랭크 샤프트의 위상 변화 혹은 캠 샤프트의 위상 변화로부터 엔진 회전수를 검출하여 그에 대한 정보를 제어부(40)에 인가한다.The RPM sensor 10 detects the engine speed from the phase change of the crankshaft or the phase change of the camshaft, and applies information about the engine speed to the controller 40.

수온센서(20)는 엔진을 순환하는 냉각수의 온도를 검출하여 그에 대한 정보를 제어부(40)에 제공한다.The water temperature sensor 20 detects a temperature of the coolant circulating in the engine and provides information about the temperature to the controller 40.

산소센서(30)는 리니어 산소센서로, 배기 매니폴더에 장착되어 희박 혹은 농후에 대한 공연비를 검출하여 그에 대한 정보를 제어부(40)에 제공한다.Oxygen sensor 30 is a linear oxygen sensor, mounted on the exhaust manifold to detect the air-fuel ratio for lean or rich and provides information about it to the controller 40.

제어부(40)는 냉간 시동 직후 일정기간 동안의 아이들 구간에서 산소센서(20)로부터 측정된 공연비가 일정기준치를 초과하면 초과된 양만큼 난기후 상태의 분사시간(EOIT : End Of Injection Time)에 대비하여 일정비율로 최대값까지 감소시켜 분사된 연료량이 흡기 포트에서 최대한 증발된 후 연소실로 유입되도록 한다.If the air-fuel ratio measured from the oxygen sensor 20 in the idle section for a period immediately after the cold start exceeds a certain reference value, the controller 40 prepares for the end of injection time (EOIT) by the amount exceeded. In order to reduce the maximum value at a constant rate, the injected fuel amount is evaporated as much as possible from the intake port and then introduced into the combustion chamber.

분사장치(50)는 상기 제어부(40)의 제어신호에 따라 노즐의 개폐시간이 조정되어 운전조건에 따라 결정된 연료량을 대응되는 연소실에 분사한다.The injector 50 adjusts the opening / closing time of the nozzle according to the control signal of the controller 40 to inject the fuel amount determined according to the operating conditions to the corresponding combustion chamber.

전술한 바와같은 기능을 포함하는 본 발명에서 냉간 시동 직후 에미션을 저감 제어하는 동작은 다음과 같다.In the present invention including the function as described above, the operation of reducing the emission immediately after the cold start is as follows.

도시되지 않은 이그니션 스위치의 온 접점이 검출되면 제어부(40)는 RPM센서(10)로부터 엔진 회전수의 정보를 검출하고, 수온센서(20)로부터 냉각수의 온도를 검출하며, 산소센서(30)로부터 공연비의 정보 등을 포함하는 제반적인 운전정보를 검출한다(S101).When the on contact of the ignition switch (not shown) is detected, the controller 40 detects information of the engine speed from the RPM sensor 10, detects the temperature of the coolant from the water temperature sensor 20, and from the oxygen sensor 30. General driving information including air fuel ratio information is detected (S101).

상기 검출되는 운전정보에서 RPM센서(10)의 정보 및 수온센서(20)의 정보가 냉간 상태에서 엔진이 시동 온 되었는지 판단한다(S102).In the detected operation information, the information of the RPM sensor 10 and the information of the water temperature sensor 20 determine whether the engine is started on in a cold state (S102).

상기 S102의 판단에서 냉간 상태의 엔진 시동 온이면 엔진 시동 온 이후 설정된 일정시간 경과되었는지 판단한다(S103).If it is determined in S102 that the engine is turned on in the cold state, it is determined whether a predetermined time has elapsed since the engine started on (S103).

상기 S103의 판단에서 엔진 시동 후 설정시간이 경과되었으면 제어부(40)는 엔진의 운전이 정상을 유지하는 것으로 판단하고 정상적인 분사시간을 적용하여 분사장치(50)를 제어한다(S109).When the set time has elapsed after the engine is started in the determination of S103, the controller 40 determines that the operation of the engine is normal and controls the injection device 50 by applying the normal injection time (S109).

그러나, 상기 S103의 판단에서 엔진 시동 후 설정시간이 경과되지 않았으면 제어부(400는 산소센서(30)로부터 시동 직후의 공연비를 검출하고(S104), 산소센서(30)의 활성화가 완료되었는지 판단한다(S105).However, if the set time after the engine start has not elapsed in the determination of S103, the controller 400 detects the air-fuel ratio immediately after the start from the oxygen sensor 30 (S104), and determines whether the activation of the oxygen sensor 30 is completed. (S105).

상기 S105에서 산소센서(30)의 활성화가 완료되지 않았으면 시동시의 분사시간을 적용하여 분사장치(50)를 제어하고(S108), 산소센서(30)의 활성화가 완료되었으면 시동시점에서 검출된 냉각수의 온도와 공연비를 설정된 맵에 적용하여 분사시간의 보정값을 결정한다(S106).If the activation of the oxygen sensor 30 is not completed in S105, the injection device 50 is controlled by applying the injection time at start-up (S108), and when the activation of the oxygen sensor 30 is completed, it is detected at the start time. The correction value of the injection time is determined by applying the temperature of the cooling water and the air-fuel ratio to the set map (S106).

이후, 기본 분사시간의 제어값에서 냉각수의 온도와 공연비의 조건으로 결정된 분사시간의 제어값을 차 연산하여 최종적인 분사시간의 제어값을 계산한 다음 분사장치(50)를 제어하여 냉간 시동 직후에 발생되는 에미션을 안정되게 한다(S107).Subsequently, the control value of the injection time determined by the condition of the coolant temperature and the air-fuel ratio is calculated from the control value of the basic injection time to calculate the final injection time control value, and then the injection device 50 is controlled to immediately after cold start. The generated emission is stabilized (S107).

도 3에 도시된 바와 같이 엔진이 시동 온(A지점) 이후 산소센서(30)의 활성화가 이루어지면(B지점) 공연비에 따라 설정된 일정시간 동안 분사시간의 보정값을 적용함으로써, 냉간 상태의 초기 시동 직후 웰 웨이팅이 발생되지 않도록 하여 에미션의 안정화를 제공한다.
이상에서 본 발명의 실시예에 대하여 상세하게 설명하였지만 본 발명의 권리범위는 이에 한정되는 것은 아니고 다음의 청구범위에서 정의하고 있는 본 발명의 기본 개념을 이용한 당업자의 여러 변형 및 개량 형태 또한 본 발명의 권리범위에 포함된다.As shown in FIG. 3, when the engine is activated after the start of the engine (point A), the activation of the oxygen sensor 30 is performed (point B). Well weighting does not occur immediately after startup to provide stabilization of the emission.
Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It is included in the scope of rights.
