본 발명은 디젤엔진의 시동보조장치로 사용하는 진각장치장치에 있어서, 스텝핑모터를 이용하여 진각장치를 제어함으로서 원가절감과 진각사양의 변경이 용이 하게 한 디젤엔진의 시동보조 진각장치제어회로와 그 제어방법에 관한 것이다.The present invention relates to a starter advance control device for a diesel engine, in which a stepping motor is used to control the advance device to reduce the cost and change the advance specifications, and the like. It relates to a control method.
일반적으로 디젤엔진의 시동보조장치로 흡기공기온도 또는 압축온도를 상승키위한 에어히터 또는 글러우플러그에 연료분사기를 진각시키도록 진각장치가 부착된다.In general, a starter for a diesel engine is provided with an advance device for advancing the fuel injector to an air heater or a glove plug for raising the intake air temperature or the compression temperature.
이러한 종래의 진각장치는 제 1 도에 나타낸 바와같이, 진각장치(10), 타이머(30), 연료피드펌프(40)에서, 상기 진각장치(10)의 진각레버(11)를 케이블(20)로 연결하여 케이블의 조작으로 연료분사기를 진각하도록 이루어진 케이블타입의 진각장치이다.As shown in FIG. 1, the conventional advancing device includes the advancing lever 11 of the advancing device 10 in the advancing device 10, the timer 30, and the fuel feed pump 40. As shown in FIG. It is a cable type advance device made to advance the fuel injector by operating the cable.
또한, 도면에 표시하지 않은 왁스(WAX)의 온도에 따른 체적변화를 이용하여 진각레버(11)를 당기는 왁스타입이 있다.In addition, there is a wax type that pulls the advance lever 11 by using a volume change according to the temperature of the wax (WAX) not shown in the drawing.
그러나, 이러한 종래 장치는 운전자가 진각레버를 직접 조절하여야 하는 불편함이 있고, 왁스 타입의 경우에는 그 가격이 고가이어서 원가 상승의 요인이 되었다.However, such a conventional device is inconvenient for the driver to adjust the advance lever directly, and in the case of the wax type, the price is expensive, which causes a cost increase.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로 냉각수 온도에 따라 진각장치를 제어하기 위하여 스텝핑 모터를 구비하여, 자동적으로 진각장치를 작동할 수 있는 디젤엔진의 시동보조 진각장치 제어회로 와 그 제어방법을 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above is provided with a stepping motor to control the advance device in accordance with the coolant temperature, starting auxiliary advance control device of the diesel engine that can operate the advance device automatically And a control method thereof.
이하 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail.
본 발명 장치는 제 2 도에 나타낸 바와같이, 디젤엔진을 제어하는 CU(70)와; 연료 분사시기를 진각시키는 진각장치(10)에 있어서; 냉각수의 온도를 측정하는 온도센서(60)와; 스텝핑모터(50)로 구성함을 그 기술적 구성상의 특징으로 한다.The apparatus of the present invention, as shown in FIG. 2, includes a CU 70 for controlling a diesel engine; In the advance device 10 for advancing the fuel injection timing; A temperature sensor 60 for measuring the temperature of the cooling water; The configuration of the stepping motor 50 is characterized by its technical configuration.
상기 스텝핑모터(50)는 상기 온도센서(60)에서 측정한 냉각수의 온도가 일정온도 이하이면 동작을하여 진각장치를 동작 할 수 있도록 한다.The stepping motor 50 may operate when the temperature of the cooling water measured by the temperature sensor 60 is below a predetermined temperature to operate the advance device.
상기 CU(70)는 냉각수온도가 일정온도 이상 될 때까지 스텝핑모터를 구동한다.The CU 70 drives the stepping motor until the coolant temperature becomes a predetermined temperature or more.
이러한 본 발명 장치의 작용효과 및 실시예를 제 2 도 내지 제 4 도를 참조하여 설명하면 다음과 같다.If described with reference to Figures 2 to 4 the effect and the embodiment of the device of the present invention.
먼저 제 3 도는 스텝핑모터(50)와 진각장치(10)와의 결합을 나타낸 일예로 스텝핑모터(50)의 구동축이 CU(70)의 제어전류에 따라 회전하여, 진각장치(10)의 중심축을 회전시킬수 있다.First, FIG. 3 illustrates an example of coupling the stepping motor 50 and the advance device 10. The driving shaft of the stepping motor 50 rotates according to the control current of the CU 70, thereby rotating the central axis of the advance device 10. As shown in FIG. You can.
이러한 동작을 제 4 도를 참조하여 설명하면, 운전자가 스타터스위치를 예열상태로 놓게 되면, 초기시동시 시동이 잘 걸리수 있도록, 흡입공기온도를 상승시키거나 압축온도를 상승시키기 위하여, CU(70)는 글로우 플러그를 예열하게 된다.Referring to FIG. 4, when the driver puts the starter switch in a preheated state, the CU 70 may be used to increase the intake air temperature or increase the compression temperature so that startup can be performed well at initial startup. ) Preheats the glow plug.
한편, 냉각수온도가 일정온도, 예를 들어 40℃까지는 연료분사시기를 진각시켜, 시동이 잘 걸리수 있도록, 스텝핑모터(50)를 동작시켜 진각시키게 된다.On the other hand, when the coolant temperature is a predetermined temperature, for example, 40 ℃ advances the fuel injection timing, the stepping motor 50 is operated to advance the engine so as to start up well.
냉각수온이 40℃이상이 되면, 스텝핑모터(50)를 동작을 멈추게 되어, 진각이 멈추게 된다.When the cooling water temperature is 40 ° C. or more, the stepping motor 50 is stopped, and the advance is stopped.
이상에서 살펴 본 바와 같이, 본 발명 장치는 진각사양의 변경이 용이하며, 스텝핑모터의 설치위치가 자유롭고, 타 방식보다 원가를 절감하여 줄 수 있는 것이다.As described above, the device of the present invention is easy to change the advance specifications, the installation position of the stepping motor is free, it is possible to reduce the cost than other methods.
