Since the pump and the motor are installed in a housing and the fuel is always filled in the inside of the housing, There is no need for a separate device.
연료의 공급은 엔진에서 최대로 필요로 하는 양보다 더 많은 양의 연료를 공급해주어 연료계통내의 압력을 일정 수준으로 유지시켜 주어 어떤 운전조건하에서도 연료부족 현상이 일어나지 않도록 하고 있다.The supply of fuel supplies a greater amount of fuel than the maximum amount required by the engine to maintain a certain level of pressure in the fuel system so that fuel shortage does not occur under any operating condition.
상기 연료 필터는 연료 중에 포함된 먼지나 수분을 제거 분리해주는 장치이며, 미세한 불순물까지 여과할 수 있는 성능을 구비하게 된다.The fuel filter is a device for removing and separating dust and moisture contained in fuel, and has a capability of filtering fine impurities.

종래에는 제5도에서와 같이 변속제어유닛(220)에서 점화속도지연신호를 전자제어유닛트(200)에 출력하면 이 전자제어유닛트(200)는 일정한 시간동안 정해진 값만큼만 점화시간을 지연함으로써, 공기밀도가 저하되는 고산지대와 같은 지역의 주행시 변속레버의 작동이 원활하게 수행되지 못하는 문제점과 변속시 점화불꽃에 의해 충격이 발생되는등의 문제점이 있었다.Conventionally, as shown in FIG. 5, when the shift control unit 220 outputs an ignition speed delay signal to the electronic control unit 200, the electronic control unit 200 delays the ignition time by a predetermined value for a predetermined time, There is a problem that the operation of the shift lever can not be performed smoothly when the vehicle is traveling in the same area as the high mountains where the density is lowered, and the shock is generated due to the ignition flame at the time of shifting.
본 발명은 상기와 같은 사정을 고려하여 이루어진 것으로, 그 목적은 변속제어유닛에서 점화속도를 지연하도록 신호를 출력하면 전자제어유닛에서 대기압에 반비례 하도록 점화속도를 제어시킴으로써 고산지대에서의 변속시 점화불꽃에 의한 충격을 방지함과 동시에 원활한 변속레버의 작동 및 변속기의 내구성을 강화할 수 있도록 한 자동 변속기의 조작성능 향상장치에 관한 것이다.SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and an object of the present invention is to provide an electronic control unit that controls the ignition speed so as to be in inverse proportion to the atmospheric pressure in the electronic control unit when a signal is output to delay the ignition speed in the shift control unit, And to improve the durability of the transmission and the operation performance of the automatic transmission.
본 발명은 상기와 같은 목적을 달성하기 위하여 점화지연신호를 출력하는 변속제어유닛의 신호에 의해 전자제어유닛이 점화지연량이 대기압에 반비례하도록 제어ㆍ출력하여 고산지대에서의 주행중의 변속시 점화불꽃에 의한 충격방지 및 변속레버가 원활하게 작동되도록 하는 자동 변속기의 조작성능 향상장치를 제공함에 의해 달성된다.In order to achieve the above-mentioned object, the electronic control unit controls and outputs the ignition delay amount in inverse proportion to the atmospheric pressure by the signal of the shift control unit for outputting the ignition delay signal, And an automatic transmission performance improvement device for smoothly operating the shift lever.
다음 본 발명의 실시예를 도면에 의거하여 구체적으로 설명 하겠다.BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described in detail with reference to the drawings.

The apparatus for improving the operating performance of the automatic transmission includes a shift control unit for outputting an ignition delay signal in inverse proportion to the atmospheric pressure Unit 22, and an electronic control unit 20 for receiving the ignition delay signal, controlling the inverse proportion to the atmospheric pressure, delaying the ignition time, and outputting it again.
다시 설명하면 점화지연신호를 출력하는 변속제어유닛(22)의 신호에 의해 전자제어유닛(20)이 점화지연량이 대기압에 반비례하도록 제어ㆍ출력하여 고산지대에서의 주행중 변속시 점화불꽃에 의한 충격방지 및 변속레버가 원활하게 작동되도록 하는 것이다.The electronic control unit 20 controls and outputs the ignition delay amount so that the ignition delay amount is inversely proportional to the atmospheric pressure by the signal of the shift control unit 22 that outputs the ignition delay signal so as to prevent the shock caused by the spark during ignition And the shift lever are smoothly operated.
