본 고안은 엔진 오일의 교환 시기를 자동으로 검출하여 운전자에게 알리도록 한 엔진 오일 교환시기 검출장치에 관한 것이다.The present invention relates to an engine oil change time detection device for automatically detecting the engine oil change time to inform the driver.
현재 차량의 엔진 오일 교환은 자동차 사용자용 매뉴얼에 명기되어 있는 엔진 오일 교환 주기에 따라 실시하도록 하고 있다. 그러나 이것은 차량 운전 지역의 기후나 운전 조건 차이에 따른 엔진 오일 열화 정도의 차를 고려하여 작성된 것이 아니기 때문에 실제적으로는 엔진 오일 교환의 최적시기 보다 빠르거나 늦게 하는 것이 일반적이다.Currently, the engine oil change of the vehicle is to be performed according to the engine oil change interval specified in the vehicle user manual. However, since this is not made in consideration of the difference in the degree of engine oil deterioration due to the difference in weather or driving conditions in the vehicle driving region, it is generally practical to be earlier or later than the optimum time of engine oil change.
엔진 오일 교환을 엔진 오일 교환 최적시기 보다 빠르게 할 때는 엔진 성능 및 내구성에는 문제가 없으니 반면 빈번한 오일 교환으로 운전자에게는 필요 이상의 비용 부담이 있게 된다. 반면에 엔진 오일 교환시기를 엔진 오일 교환 최적시기 보다 늦게 할 때는 엔진의 성능 및 내구력에 악영향을 초래하게 된다. 운전자가 수시로 판단하여 엔진 오일을 교환한다는 것은 비현실적이고 따라서 상기 문제가 빈번히 발생하는 것이다.When the engine oil change is faster than the engine oil change optimum time, there is no problem with engine performance and durability, while frequent oil changes are more expensive than necessary for the operator. On the other hand, if the engine oil change time is later than the engine oil change optimum time, it will adversely affect the engine performance and durability. It is unrealistic to change the engine oil at the discretion of the driver from time to time and thus the problem occurs frequently.
따라서, 본 고안의 목적은 자동적으로 엔진 오일시기를 검지하여 운전자에게 알려줌으로써 오일 교환시기를 최적화할 수 있도록 하여 엔진의 성능과 내구력을 향상시키기 위한 차량의 엔진 오일 교환시기 자동 지시 장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide an automatic indication device of an engine oil change time of a vehicle for automatically detecting engine oil time and informing a driver so as to optimize the oil change time, thereby improving engine performance and durability. .
본 고안의 근본 원리는 엔진 오일의 열화 정도를 감지하여 그 정도에 대응하는 저항 변화에 의해 검출 전류로부터 엔진 오일교환시기를 자동검지 및 지시하는 것이다.The basic principle of the present invention is to detect the degree of deterioration of the engine oil and to automatically detect and instruct the engine oil replacement time from the detected current by the resistance change corresponding to the degree.
본 고안에서는 이러한 센서가 제공된다. 제 1 도는 본 고안에서 제공되는 엔진 오일 점도 센서의 기본 구조도로서 엔진 오일(1) 내에 센서(2)가 설치된 것을 보인 것이다.In the present invention, such a sensor is provided. 1 is a basic structural diagram of an engine oil viscosity sensor provided in the present invention, showing that the sensor 2 is installed in the engine oil 1.
엔진 오일 점도 센서(2)는 절연저항제(2A)와 그 양측에 부착된 전극(2C), (2B)으로 구성되고 전원(3)이 전극에 연결된다. 저항에 걸리는 전압(V)은 전류(I)와 저항(R)과의 곱으로 표시되고 전원이 12V로 일정할 때 저항(R)이 오일 열화에 따라 변하면 전류(2)가 변하여 센서 신호로서 활용될 수 있다.The engine oil viscosity sensor 2 is composed of an insulating resistor 2A and electrodes 2C and 2B attached to both sides thereof, and a power source 3 is connected to the electrode. The voltage applied to the resistance (V) is expressed as the product of the current (I) and the resistance (R). When the resistance (R) changes with oil deterioration when the power is constant at 12 V, the current (2) changes and is used as a sensor signal. Can be.
엔진 오일은 열화됨에 따라 저항이 커지는 특성이 있는데 오일 열화에 따라 검출 전류가 감소되는 것을 알수 있다.Engine oil has a characteristic of increasing resistance as it deteriorates, and it can be seen that the detection current decreases as the oil deteriorates.
제 2 도는 상기 엔진 점도 센서와 더불어 엔진 오일 온도 센서를 엔진 오일 팬(pan)(4)에 설치하고 센서 출력을 전자 제어장치(ECU)(5)에 연결하여 계기판(6)에 교환시기를 알리도록 한 연결 기구를 보이고 있다.2 shows an engine oil temperature sensor in addition to the engine viscosity sensor in the engine oil pan 4 and connects the sensor output to the ECU 5 to inform the instrument panel 6 of the time of replacement. I'm showing a connection mechanism.
엔진(7)은 실린더 헤드(7A)와 실린더 블록(7B)으로 되어 있고 오일팬(pan)에는 오일(1)이 들어 있으며 오일(pan) 하단 벽부에 상기 엔진 오일 점도 센서(2) 및 온도 센서(8)가 설치되어 오일 상태를 점검하는 것이다.The engine 7 has a cylinder head 7A and a cylinder block 7B, the oil pan contains oil 1 and the engine oil viscosity sensor 2 and the temperature sensor on the bottom wall of the oil pan. (8) is installed to check the oil condition.
온도 센서(8)의 설치 이유는 일반적으로 알려진 오일 온도 대비 점도(J0)관계를 이용하기 위한 것이다.The reason for the installation of the temperature sensor 8 is to use a viscosity J 0 relationship relative to the oil temperature generally known.
제 3 도의 흐름도는 ECU가 처리하는 것으로 그 상세 내용은 다음과 같다.The flowchart of FIG. 3 is processed by the ECU. Details are as follows.
먼저 스텝 1에서 엔진 오일 온도 센서의 신호를 받아들여 관계 테이블로 부터 엔진 오일 사용 가능 한계치(J1)를 산출하고, 스텝 2와 같이 엔진 오일 점도 센서(2)의 전류를 측정하여 전류로부터 실제 점도(J2)를 산출한다. 이러한 J1, J2값을 가지고 스텝 3과 같이 J2J1인지를 비교하여 그러하다면 스텝 4와 같이 엔진 오일 교환시기임을 계기 수단(6)에 알리고 J2J1인 경우에는 처음으로 복귀한다.First, the engine oil temperature limit value (J 1 ) is calculated from the relationship table by receiving the signal of the engine oil temperature sensor in step 1, and the actual viscosity is measured from the current by measuring the current of the engine oil viscosity sensor (2) as in step 2. Calculate (J 2 ). Compare these J 1 , J 2 values with J 2 J 1 as in step 3, and if so, inform the instrument means 6 that the engine oil change time is as in step 4, and return to the beginning if J 2 J 1 . .
이와 같이 본 고안에 따라서 엔진 오일 교환시기를 자동적으로 운전자에게 알리기 때문에 빈번한 엔진 오일 교환에 따른 비용 상승을 줄일 수 있고 또한 엔진 오일 교환시기를 최적화함으로 엔진 성능 및 내구력이 향상된다.In this way, according to the present invention, the engine oil change time is automatically notified to the driver, thereby increasing the cost of frequent engine oil change, and also optimizing the engine oil change time, thereby improving engine performance and durability.
