일반적으로 전자제어식 연료분사장치에서 사용된 드로틀 포지션센서는 엔진에 장착하기전에 전용검사장비를 사용하여 정상작동 유무를 확인하거나,이러한 검사 과정을 거치지 않고 차량에 직접 장착하여 차량의 성능을 테스트함으로써,드로틀 포지션센서의 정상작동 유무를 간접적으로 확인하는등의 방법을 사용했었다.In general, the throttle position sensor used in the electronically controlled fuel injection device uses a dedicated inspection equipment to check the normal operation before mounting on the engine, or directly mounted on the vehicle without this inspection process to test the performance of the vehicle. Indirectly, the throttle position sensor was used to check the normal operation.
그렇지만,상기한 종래의 검사 방법에 있어서는 고가의 장비를 사용하게 되는 비용상의 부담 및 검사 시간의 지연등으로 비효율적인 측면이 있었고,검사 생략을 하게 될 경우,엔진 성능의 비정확성으로 인하여 제품의 신뢰성 및 사후 정비 등을 요구하게 되는 등의 폐단이 있었다.However, in the conventional inspection method described above, there is an inefficient aspect due to the cost burden of using expensive equipment and delay of inspection time, and when the inspection is omitted, the reliability of the product due to the inaccuracy of the engine performance. And post-maintenance.
본 발명은 상기한 종래의 제반 문제점을 감안하여 안출된 것으로,본 발명의 목적은 차량엔진 제어에 필요한 드로틀 포지션센서 단품의 정상 유무를 간단하게 체크할 수 있도록 하는 수단을 제공하는데 있는 것이다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a means for easily checking the normal presence or absence of a single throttle position sensor required for vehicle engine control.
이와 같은 목적을 달성하기 위한 본 발명은, 드로틀밸브의 축 일단에는 각도기를 설치하고, 타단에는 드로틀 포지션센서를 착탈시킬 수 있도록 구성하며, 드로틀밸브는 각도조정기에 의하여 각도를 가변시킬 수 있도록 한 드로틀 포지션센서 검사장치를 제공하여,각도기에 나타난 드로틀 밸브의 각과 드로틀 포지션센서의 출력단자 전압을 표와 대조하여 드로틀 포지션센서의 정상 유무를 검사할 수 있도록 한 것으로 ,이하, 첨부된 도면에 의하여 본 발명의 구성 및 작용 효과를 상세히 설명하기로 한다.In order to achieve the above object, the present invention provides a protractor at one end of the shaft of the throttle valve and a detachable throttle position sensor at the other end thereof, and the throttle valve is capable of changing the angle by the angle adjuster. By providing a position sensor inspection device, to check the normal presence of the throttle position sensor by comparing the angle of the throttle valve and the output terminal voltage of the throttle position sensor shown in the protractor, hereinafter, the present invention by the accompanying drawings The configuration and effect of the will be described in detail.
본 발명은 제1도에 도시한 바와 같이, 드로틀 포지션센서의 작동 상태를 검사하는 장치에 있어서,하부로 드로틀 포지션센서(18)가 착탈식으로 설치된 통체(10)내의 빈 공간에는 드로틀밸브(12)와 일체인 축(14)의 상,하 단부를 축결합시켜 회동 개폐되게 하되, 상기 축(14)의 상부 끝단에는 선회되면서 가변되는 각이 표시되도록 지침(15)을 갖는 각도기(16)가 설치되고, 상기 드로틀 밸브(12)에는 일단이 고정체(20)에 설치된 텅버클인 각도조정기(22)를 설치하여 각도가 가변될 수 있게 한 것이다.The present invention, as shown in Figure 1, in the apparatus for checking the operating state of the throttle position sensor, the throttle valve 12 in the empty space in the cylindrical body 10 is detachably installed in the lower throttle position sensor 18 The upper and lower ends of the shaft (14) integral with the shaft to be rotated open and close, the protractor 16 having a guide (15) is installed on the upper end of the shaft (14) so that the angle is changed while turning In addition, the throttle valve 12 is provided with an angle adjuster 22, one end of which is a buckle buckle installed in the fixed body 20, so that the angle can be varied.
이와 같이 구성된 본 발명은 드로틀 포지션센서(18)에 전압(5볼트)을 인가시킨 상태에서 각도조정기(22)인 텅버클을 돌려 드로틀밸브(12)가 측정하고자 하는 각도에 맞추고, 드로틀 포지션센서(18)의 출력 전압을 측정하여 표 1과 같은 기준표와 대조하여 드로틀 포지션센서(18)가 정상적으로 작동하는가를 확인한다.The present invention configured as described above rotates the tongue buckle, which is the angle adjuster 22, in a state where voltage (5 volts) is applied to the throttle position sensor 18 to match the angle that the throttle valve 12 is to measure, and the throttle position sensor ( Measure the output voltage of 18) and check whether the throttle position sensor 18 operates normally by comparing with the reference table as shown in Table 1.
표 1 은 드로틀밸브(12)의 개폐각이 0°에서 90°까지 변화될 때, 출력단자(A,B)로부터 측정되는 전압을 기록한 것으로,검사시 각도기(16)에 나타난 각도와 츨력단다(A,B)로부터 측정된 전압을 대비하여 출력전압이 정상 범위에 드는지 확인하면 되는 것으로,예를 들면 드로틀밸브(12)의 각이 0°인 경우, 즉 완전폐쇄 상태에서는 출력전압이 0.02볼트 이하를 가리키면 정상이고, 드로틀밸브(12)의 각이 90°인 경우 즉, 완전개방 상태에서는 출력전압이 4.98볼트 내지 5 볼트의 범위를 가리키면 정상인 것이다.Table 1 records the voltages measured from the output terminals A and B when the opening and closing angle of the throttle valve 12 is changed from 0 ° to 90 °, and the angles and output stages shown in the protractor 16 during the inspection ( It is necessary to check whether the output voltage is within the normal range compared to the voltage measured from A and B). For example, when the angle of the throttle valve 12 is 0 °, that is, in the fully closed state, the output voltage is 0.02 volts or less. If is indicated that is normal, the angle of the throttle valve 12 is 90 °, that is, in the fully open state if the output voltage is in the range of 4.98 volts to 5 volts is normal.
이처럼 본 발명은 각도조정기를 조정항 드로틀밸브의 각을 변화시켜주면서 드로틀 포지션센서의 출력전압을 측정하여 기준표와 대비함으로써, 드로틀 포지션센서의 정상 유무를 간단하게 검사할 수 있는 것으로, 본 발명에 의하면 드로틀 포지션센서 단품의 정상 유무를 검사할 경우, 그 검사는 고가의 장비를 사용하지 않고도 신속하게 확인할 수 있고, 또한 차량을 효율적으로 정비할 수 있는 유용한 효과도 갇게 된다.As described above, the present invention measures the output voltage of the throttle position sensor while changing the angle of the throttle valve by adjusting the angle adjuster and compares it with the reference table, thereby easily checking whether the throttle position sensor is normal. When checking the throttle position sensor unit for normal operation, the inspection can be quickly confirmed without using expensive equipment, and also useful effects for efficiently servicing the vehicle are trapped.
