Description
본 발명은 자동차의 엔진제어유니트 장착구조에 관한 것으로, 특히 엔진제어유니트가 에어클리너에 장착되는 자동차의 엔진제어유니트 장착구조에 관한 것이다.The present invention relates to an engine control unit mounting structure of an automobile, and more particularly, to an engine control unit mounting structure of an automobile in which the engine control unit is mounted to an air cleaner.
자동차에 의한 대기오염이 심각해지면서 자동차의 배기가스 규제가 강화되었으며, 정해진 배기가스 규제치를 만족시키기 위해서는 엔진의 운전조건에 따라 공연비, 점화시기, EGR(exhaust gas recirculation)량 등을 지속적으로 세밀하게 조정해 주어야 한다.As the air pollution caused by automobiles became more severe, the exhaust gas regulations of automobiles were tightened, and in order to satisfy the prescribed exhaust gas regulation values, the air-fuel ratio, ignition timing, and exhaust gas recirculation (EGR) were continuously adjusted in detail according to the engine operating conditions. You must do it.
이를 위하여 엔진의 작동을 마이크로 컴퓨터를 이용하여 전자적으로 제어하게 되었는데, 통상 상기 마이크로 컴퓨터를 엔진제어유니트 즉, ECU(engine control unit)라고 호칭한다.To this end, the operation of the engine is controlled electronically using a microcomputer. The microcomputer is generally referred to as an engine control unit, that is, an engine control unit (ECU).
한편, 상기 엔진제어유니트는 차량 실내의 인스트루먼트패널 안쪽에 설치되므로 엔진제어유니트와 엔진의 각 액츄에이터들을 연결하는 와이어하네스는 대쉬패널을 관통하여야만 한다.On the other hand, since the engine control unit is installed inside the instrument panel inside the vehicle, the wire harness connecting the engine control unit and the actuators of the engine must pass through the dash panel.
즉, 엔진과 엔진제어유니트를 각각 따로 장착한 후, 엔진의 각 액츄에이터에 와이어하네스의 한쪽 단부를 연결하고, 이 와이어하네스의 타단을 대쉬패널에 형성된 홀을 통해 삽입하여 엔진제어유니트에 연결하여야만 하였다.In other words, after the engine and the engine control unit were separately installed, one end of the wire harness should be connected to each actuator of the engine, and the other end of the wire harness should be inserted through the hole formed in the dash panel to connect the engine control unit. .
따라서, 작업이 불편하고 공정수와 작업 시간이 증가되는 문제점이 있었으며, 상기 대쉬패널에 형성된 홀에 와이어하네스를 삽입할 때 종종 와이어하네스가 파손되는 현상이 발생할 뿐만 아니라, 상기 홀이 엔진룸과 실내를 격리하는 대쉬패널에 형성된 것이므로 이 홀을 통하여 엔진룸 내의 소음이 실내로 유입되는 문제점도 있었다.Therefore, there is a problem that the work is inconvenient, the number of processes and the work time is increased, and when the wire harness is inserted into the hole formed in the dash panel, the wire harness is often broken, and the hole is in the engine room and the room. Since it is formed in the dash panel to isolate the problem that the noise in the engine room is introduced into the room through this hole.
또한, 엔진제어유니트와 엔진과의 거리가 멀기 때문에 상기 와이어하네스의 길이가 길어질 수 밖에 없어 재료비가 증가되며, 길이가 길어진 만큼 전압강하에 의해 시그널이 미약하게 전달되어 정확한 제어작용이 이루어지지 않는 경우가 발생하기도 하였다.In addition, since the distance between the engine control unit and the engine is far, the length of the wire harness is inevitably lengthened, and the material cost increases. As the length increases, the signal is weakly transmitted due to the voltage drop, and thus the accurate control action is not achieved. Was also generated.
또한, 정비시에도 액츄에이터들과 이를 제어하는 엔진제어유니트가 각각 엔진룸과 실내에 떨어져 있고, 장착상태의 엔진제어유니트를 분리하기 위해서는 먼저 상기 인스트루먼트패널 상에 설치된 커버를 제거해야 하는 등 정비·점검시의 작업효율이 여러 모로 저하되는 문제점이 있었다.During maintenance, the actuators and the engine control unit that controls them are separated from the engine room and the room, respectively, and the cover installed on the instrument panel must be removed before the engine control unit can be removed. There was a problem that the work efficiency of the city is reduced in many ways.
이에 상기 문제점들을 해결하고자 엔진제어유니트를 엔진룸 내에 설치하는 방안을 모색하였으나, 엔진룸에는 엔진과 그 외 여러 부대장치들이 빼곡이 설치되어 있어서 설치공간을 확보하기가 용이하지 않고, 또한 엔진에 의한 열해(熱害)의 우려가 있어 적절한 설치위치의 선정이 난해하였다.In order to solve the above problems, the engine control unit has been sought to be installed in the engine room. However, the engine room and other auxiliary devices are installed in the engine room, so it is not easy to secure an installation space, and Due to the risk of thermal damage, it was difficult to select an appropriate installation location.
이에 본 발명은 상기와 같은 점들을 감안하여 안출된 것으로, 엔진에 의한 열해의 우려 없이 엔진제어유니트가 엔진룸의 내부에 설치됨으로써 장착 작업이 용이해지고, 공정수와 작업시간이 감소하며, 와이어하네스 관통홀을 통한 소음전달문제가 해결되고, 이 홀에 와이어하네스를 삽입할때의 파손에 따른 불량 문제도 해결되며, 와이어하네스의 길이가 짧아짐으로써 재료비가 절감되고 전압강하에 의한 오작동 문제가 해결될 뿐만 아니라, 정비 및 점검 작업도 보다 간편하게 실시할 수 있도록 된 자동차의 엔진제어유니트 장착구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above points, the engine control unit is installed inside the engine room without fear of thermal damage by the engine, the mounting work is easy, the number of processes and working time is reduced, the wire harness The problem of noise transmission through the through hole is solved, and the problem caused by the breakage when the wire harness is inserted into the hole is also solved. The shorter wire harness length can reduce the material cost and solve the problem of malfunction due to voltage drop. In addition, the object of the present invention is to provide an engine control unit mounting structure of a vehicle, which is capable of performing maintenance and inspection tasks more easily.
상기와 같은 목적을 달성하기 위한 본 발명은, 엔진룸 내부의 에어클리너에 엔진제어유니트가 장착되는 자동차의 엔진제어유니트 장착구조에 있어서, 상기 에어클리너의 엔진과 마주보지 않는 한쪽 벽면에 개구부가 형성되고, 이 개구부로 상기 엔진제어유니트의 장착면측 몸체가 삽입/장착되는 것을 특징으로 한다.The present invention for achieving the above object, in the engine control unit mounting structure of the vehicle in which the engine control unit is mounted on the air cleaner in the engine room, an opening is formed on one wall surface not facing the engine of the air cleaner. And the mounting surface side body of the engine control unit is inserted / mounted into the opening.
이하, 본 발명을 첨부된 예시도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 따른 엔진제어유니트 장착상태의 사시도로서, 본 발명은 에어클리너(10)의 한쪽 벽면에 엔진제어유니트(20)가 보울트(30)를 매개로 장착되는 것을 특징으로 한다. 단, 상기 엔진제어유니트(20)는 엔진으로부터의 열해를 피하기 위하여 엔진과 마주보지 않는 에어클리너(10)의 면에 장착된다.1 is a perspective view of an engine control unit mounting state according to the present invention. The present invention is characterized in that the engine control unit 20 is mounted on one wall of the air cleaner 10 via the bolt 30. However, the engine control unit 20 is mounted on the surface of the air cleaner 10 not facing the engine in order to avoid thermal damage from the engine.
상기 장착상태의 분해 사시도인 도 2에 도시된 바와 같이, 에어클리너(10 ; 몸체 일부분만을 절개 도시하였음.)의 한쪽 벽면에 개구부(12)가 형성되고, 이 개구부(12)로 엔진제어유니트(20)의 장착면측 몸체가 삽입된다. 여기서, 장착면이라 함은 에어클리너(10)와 엔진제어유니트(20)가 상호 마주 접하게 되는 면을 말하며, 엔진제어유니트(20)에 있어서 장착면측 몸체라 함은 엔진제어유니트(20)의 장착면에서 소정 길이 돌출되어 상기 개구부(12)를 통해 에어클리너(10)의 내부로 삽입되는 엔진제어유니트(20)의 몸체를 말한다. 즉, 전자제어유니트(20)는 장착면측에 돌출된 몸체 부분만이 에어클리너(10)의 내부로 일부 삽입되는 것이고, 대부분의 나머지 몸체 부분은 에어클리너(10)의 측부 외측에 노출되는 상태로 장착된다.As shown in FIG. 2, which is an exploded perspective view of the mounting state, an opening 12 is formed on one wall surface of the air cleaner 10 (only a portion of the body is cut out), and the opening 12 forms an engine control unit ( 20) The body on the mounting surface side is inserted. Here, the mounting surface refers to the surface where the air cleaner 10 and the engine control unit 20 face each other, and the mounting surface side body in the engine control unit 20 refers to the mounting of the engine control unit 20. The body of the engine control unit 20 protrudes a predetermined length from the surface and is inserted into the air cleaner 10 through the opening 12. That is, the electronic control unit 20 is only part of the body portion protruding on the mounting surface side is inserted into the interior of the air cleaner 10, most of the remaining body portion in a state exposed to the outside of the side of the air cleaner 10 Is mounted.
상기 에어클리너(10) 몸체 외곽과 엔진제어유니트(20)의 몸체 외곽에는 상호 대응되는 위치에 보울트삽입공이 형성되는 장착단(11,21)들이 형성된다.Mounting ends 11 and 21 are formed on the outer side of the body of the air cleaner 10 and the outer side of the body of the engine control unit 20 so that the bolt insertion hole is formed at a corresponding position.
상기 장착단(11,21)들은 상기 개구부(12)에 엔진제어유니트(20)의 장착면측 몸체가 삽입되었을 때 상호 일치·밀착되며, 이들의 보울트삽입공에 상기 보울트(30)가 삽입·체결됨으로써 에어클리너(10)에 엔진제어유니트(20)가 장착된다.The mounting ends 11 and 21 are coincided with each other when the mounting surface side body of the engine control unit 20 is inserted into the opening 12, and the bolt 30 is inserted and fastened into the bolt insertion hole. As a result, the engine control unit 20 is mounted to the air cleaner 10.
또한, 상기 엔진제어유니트(20)의 장착면과 에어클리너(10) 사이에는 고무재질의 시일링(40)이 구비되어 장착면 간의 틈새를 통해 에어클리너(10)로 유입되는 외기가 새어나오지 않도록 기밀성을 유지한다.In addition, a rubber seal 40 is provided between the mounting surface of the engine control unit 20 and the air cleaner 10 so that outside air flowing into the air cleaner 10 may not leak through the gap between the mounting surfaces. Maintain confidentiality.
상기 시일링(40)은 에어클리너(10)의 장착면 표면에 형성된 홈이나 엔진제어유니트(20)의 장착면 표면에 형성된 홈에 미리 삽입되어 있게 되며, 이 상태에서 전술한 바와 같이 엔진제어유니트(20)를 에어클리너(10)에 보울트(30) 체결함으로써 시일링(40)이 에어클리너(10)와 엔진제어유니트(20)의 몸체 사이에서 압착되어 양자의 사이가 밀폐되어진다.The sealing ring 40 is previously inserted into a groove formed on the surface of the mounting surface of the air cleaner 10 or a groove formed on the surface of the mounting surface of the engine control unit 20. In this state, the engine control unit as described above. When the bolt 30 is fastened to the air cleaner 10, the seal ring 40 is compressed between the air cleaner 10 and the body of the engine control unit 20 to seal the two.

그리고, 상기 엔진제어유니트(20)의 개구부(12) 삽입면에는 도 2에 도시된 바와 같이, 다수의 냉각핀(23)이 일체로 형성되어 있어서, 장착상태에서 이 냉각핀(23)들은 에어클리너(10)로 유입되는 외기와 접촉하도록 되어 있다.(미설명 부호 22는 와이어하네스가 연결되는 커넥터이다.)In addition, as shown in FIG. 2, a plurality of cooling fins 23 are integrally formed at the insertion surface of the opening 12 of the engine control unit 20, so that the cooling fins 23 are air in the mounted state. It is made to come in contact with the outside air which flows into the cleaner 10. (22 is a connector to which a wire harness is connected.)
따라서, 엔진제어유니트(20) 자체에서 발생되는 열을 냉각하기에도 매우 유리하다.Therefore, it is also very advantageous to cool the heat generated in the engine control unit 20 itself.
또한, 비어 있는 공간인 에어클리너(10)에 엔진제어유니트(20)를 장착함으로써 설치공간 확보를 위해 엔진룸의 레이아웃을 변경할 필요가 없게 되는 장점이 있다.In addition, by mounting the engine control unit 20 in the air cleaner 10, which is an empty space, there is an advantage that it is not necessary to change the layout of the engine room to secure the installation space.
이상 설명한 바와 같이 본 발명에 따르면, 엔진에 의한 열해와 설치공간 확보의 난해함을 해결하고 엔진제어유니트가 엔진룸에 설치될 수 있게 된다.As described above, according to the present invention, it is possible to solve the problem of thermal damage caused by the engine and securing the installation space, and the engine control unit can be installed in the engine room.
따라서, 엔진과 엔진제어유니트가 가까운 거리에 있게 되고, 종전과 같이 와이어하네스를 대쉬패널에 형성된 홀에 관통시키는 작업이 필요 없게 되므로 공정수가 줄고, 와이어하네스 연결작업이 매우 간편해짐으로써 작업시간도 단축할 수 있게 되었다.Therefore, the engine and the engine control unit are in close proximity, and as there is no need to penetrate the wire harness through the hole formed in the dash panel as in the past, the number of processes is reduced and the work time of the wire harness is very simple. I can do it.
또한, 와이어하네스의 길이가 짧아져 작업에 방해를 주지 않으므로, 엔진 장착전에 와이어하네스의 일단을 엔진측에 미리 연결한 상태에서 엔진 장착 작업을 실시할 수 있게 됨으로써 에어클리너 장착후의 와이어하네스 연결작업을 보다 편리하게 실시할 수 있게 되는 장점도 있다.In addition, since the length of the wire harness is shortened, it does not interfere with the work. Therefore, the engine mounting work can be performed with one end of the wire harness connected to the engine in advance before the engine is installed, thereby connecting the wire harness after the air cleaner is installed. There is also an advantage that can be carried out more conveniently.
또한, 대쉬패널의 홀에 와이어하네스를 관통시키지 않으므로 이로 인한 와이어하네스의 파손 문제가 해결되고, 대쉬패널에 홀이 없어지므로 이 홀을 통한 실내로의 엔진소음 유입이 차단됨으로써 실내 정숙성 향상에도 도움이 된다.In addition, the wire harness does not penetrate through the hole of the dash panel, thereby solving the problem of breakage of the wire harness, and eliminating the hole in the dash panel prevents the inflow of engine noise into the room. do.
또한, 상기 와이어하네스의 길이가 짧아지므로 재료 비용을 절감할 수 있으며, 전압강하에 따른 시그널 강도 약화에 의한 오작동 및 미작동 문제를 해결할 수 있게 된다. In addition, since the length of the wire harness is shortened, it is possible to reduce the material cost and to solve the problem of malfunction and non-operation due to the weakening of the signal strength due to the voltage drop.
또한, 엔진제어유니트가 실내에 설치될 때와는 달리 본네트를 열면 바로 엔진제어유니트가 외부로 노출되고, 별도의 커버도 존재하지 않으므로 분리가 용이하여 정비 및 점검을 간편하게 실시할수 있게 되는 장점도 있다.In addition, unlike when the engine control unit is installed indoors, when the bonnet is opened, the engine control unit is immediately exposed to the outside, and since there is no separate cover, there is an advantage that the maintenance and inspection can be easily performed because the separation is easy. .
