본 발명은 내연기관용 오일젯에 관한 것으로서, 보다 상세하게는 차량의 저속 주행시와 오일의 저온시에 오일젯을 통한 오일의 분사가 효율적으로 이루어지도록 한 진공을 이용한 오일젯 전자제어장치에 관한 것이다.The present invention relates to an oil jet for an internal combustion engine, and more particularly, to an oil jet electronic control apparatus using a vacuum for efficient injection of oil through the oil jet at low speeds and at low temperatures of the vehicle.

일반적으로 최근 자동차에 엔진이 고성능화되면서 피스톤에 가해지는 열부하가 크게 증대됨에 따라 피스톤의 냉각을 위해 피스톤 내부로 오일을 순환시킬 수 있는 구조가 마련되고 있다.In general, as the engine has been improved in recent years, the heat load on the piston is greatly increased, and thus a structure capable of circulating oil inside the piston for cooling the piston is provided.

즉, 직접 분사식인 고출력의 엔진은 연소실 온도가 매우 높으므로 도 1,2에서와 같이 실린더블록(1)의 메인갤러리(2)에 오일젯(3)을 설치함으로써, 피스톤(6)의 하부로 오일을 분사하여, 상기 피스톤(6)을 효과적으로 냉각시키도록 하였다.That is, since the direct injection type high power engine has a very high combustion chamber temperature, the oil jet 3 is installed in the main gallery 2 of the cylinder block 1 as shown in FIGS. Oil was sprayed to cool the piston 6 effectively.

다시말해, 상기 오일젯(3)은 체크밸브(4)내에 구성된 피스톤(6)과 스프링에 의해 일정압력 이상이 되면 오일을 분사하게 되는데, 그 경로는 오일펌프(미도시)의 오일이 실린더블록(1)의 메인갤러리(2)를 거쳐 미도시된 메인 베어링을 윤활시키고, 다음으로 콘로드(5)의 베어링을 윤활시킨 후 콘로드(5)의 소단부 부싱과 피스톤(6)의 핀을 윤활시키게 되는 것이다.In other words, the oil jet 3 injects oil when a predetermined pressure is exceeded by the piston 6 and the spring formed in the check valve 4, and the path of the oil pump (not shown) is the cylinder block. Lubricate the main bearing (not shown) via the main gallery (2) of (1), and then lubricate the bearing of the cone rod (5), and then attach the small end bushing of the cone rod (5) and the pin of the piston (6). To be lubricated.

그러나, 종래에는 엔진의 저 RPM상태에서 오일젯(3)이 오일을 과도하게 분사 할 경우 메인갤러리(2)의 압력이 떨어져 각 주요부에 대한 윤활 즉, 메인베어링과 콘로드(5)의 베어링에 대한 윤활이 원활하게 이루어지지 못하면서 마모 및 소착이 발생하는 문제점이 있고, 이러한 문제는 곧 엔진의 출력 저하 및 배기(EMISSION)의 악화를 초래하였으며, 심할 경우 엔진에 대한 동작이 불가능해지는 단점이 있다.However, conventionally, when the oil jet 3 excessively injects oil at a low RPM state of the engine, the pressure of the main gallery 2 drops and lubricates the main parts, that is, the bearings of the main bearing and the cone rod 5. There is a problem in that wear and sintering occur while the lubrication is not performed smoothly, and this problem causes a decrease in the output of the engine and the deterioration of the exhaust (EMISSION), and in some cases, the operation of the engine is impossible.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 차량의 저속 주행시와 오일의 저온시에 오일젯을 통한 오일의 분사가 효율적으로 이루어져 메인베어링과 콘로드의 베어링에 대한 윤활이 원활하게 이루어지지 못하면서 마모 및 소착이 발생되는 문제를 개선할 수 있도록 함은 물론, 엔진의 출력 저하 및 배기가 악화되는 것을 방지할 수 있도록 하는 진공을 이용한 오일젯 전자제어장치를 제공하려는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, lubrication of the bearings of the main bearing and the cone rod by efficient injection of oil through the oil jet during low-speed running of the vehicle and low temperature of the oil This is to provide an oil jet electronic control device using a vacuum that can improve the problem of wear and seizure without being made smoothly, as well as to prevent the engine's output degradation and exhaust from deteriorating. There is this.

이하, 첨부된 도면에 의하여 본 발명의 바람직한 일실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 3은 본 발명의 일실시예로 진공을 이용한 오일젯 전자제어장치의 블럭 구성도이고, 도 4는 본 발명의 일실시예로 오일젯의 장착 상태도 이다.Figure 3 is a block diagram of an oil jet electronic control apparatus using a vacuum in one embodiment of the present invention, Figure 4 is a mounting state of the oil jet in one embodiment of the present invention.

도 3 및 도 4에 도시된 바와같이, 실린더블록(11)의 메인갤러리에 설치된 오일젯(12)이 오일펌프(13)내의 오일을 피스톤의 하부로 분사시켜, 상기 피스톤을 효과적으로 냉각시키는 장치를 구성함에 있어서,3 and 4, the oil jet 12 installed in the main gallery of the cylinder block 11 sprays the oil in the oil pump 13 to the lower part of the piston, thereby effectively cooling the piston. In constructing,

상기 피스톤으로 분사되는 오일량을 조절하는 유량조절부;A flow rate control unit controlling an amount of oil injected into the piston;

상기 유량조절부의 진공량을 조절하는 진공조절부(vacuum regulator)(40); 및A vacuum regulator 40 for adjusting the vacuum amount of the flow rate controller; And

엔진 RPM과 분사 연료량 및 오일 온도 정보로부터 상기 진공조절부(40)를 통해 이루어지는 진공펌프의 진공량을 제어하는 전자제어유닛(50); 으로 구성함을 특징으로 하는 진공을 이용한 오일젯 전자제어장치.An electronic control unit 50 for controlling a vacuum amount of a vacuum pump made through the vacuum control unit 40 from engine RPM, injection fuel amount, and oil temperature information; Oil jet electronic control device using a vacuum, characterized in that configured as.

다른 일면에 따라, 상기 유량조절부는,According to another aspect, the flow rate control unit,

상기 오일젯(12)과 오일펌프(13)를 연결하는 제 1 유로(14)에 마련되어 오일의 유량을 조절하는 오일유량 조절밸브(20);An oil flow rate control valve 20 provided in the first flow passage 14 connecting the oil jet 12 and the oil pump 13 to adjust the flow rate of the oil;

상기 오일유량 조절밸브(20)와 제 2 유로(15)를 통해 연결하되, 상기 진공조절부(40)에 의해 진공량이 조절되어 오일유량 조절밸브(20)의 열림량을 제어하는 액추에이터(30); 를 포함하여 구성함을 특징으로 한다.The actuator 30 is connected through the oil flow rate control valve 20 and the second flow path 15, and the vacuum amount is controlled by the vacuum control unit 40 to control the opening amount of the oil flow rate control valve 20. ; Characterized in that comprises a configuration.

이와같이 구성된 본 발명의 일실시예에 대한 작용을 첨부된 도 3 및 도 4를 참조하여 설명하면 다음과 같다.Referring to Figures 3 and 4 attached to the operation of an embodiment of the present invention configured as described above are as follows.

먼저, 차량의 전자제어유닛(50)은 엔진 RPM과 분사연료량은 물론 오일의 온도변화에 따라 초기 매인갤러리의 압력과 차량의 저속 주행시 발생하는 메인갤러리의 압력을 비교한 후 진공조절부(40)로 작동신호를 출력한다.First, the electronic control unit 50 of the vehicle compares the engine RPM and the amount of fuel injected, as well as the pressure of the main gallery and the pressure of the main gallery generated when the vehicle runs at low speed according to a change in temperature of the vacuum. To output the operation signal.

이때, 상기 전자제어유닛(50)은 차량의 엔진회전수가 고속모드로서 메인갤러리의 압력이 높은 경우, 상기 진공조절부(40)를 통해 유량조절부에 포함되는 액추에이터(30)로 공급되는 진공량을 크게 조절하는 제어신호를 출력하게 되는 바,At this time, the electronic control unit 50 is a high-speed mode of the engine speed of the vehicle, when the pressure of the main gallery is high, the amount of vacuum supplied to the actuator 30 included in the flow rate control unit through the vacuum control unit 40 Will output a control signal to greatly control the

상기 액추에이터(30)에서는 제 2 유로(15)를 통해 연결된 오일유량 조절밸브 (20)를 열게 되고, 이에따라 오일펌프(13)를 통해 오일젯(12)으로는 오일공급이 이루어지게 된다.In the actuator 30, the oil flow rate control valve 20 connected through the second flow path 15 is opened, and thus oil supply is made to the oil jet 12 through the oil pump 13.

그러면, 상기의 오일은 피스톤 내부로 순환되면서, 상기 피스톤을 효율적으로 냉각시킬 수 있게 된다.Then, the oil is circulated inside the piston, thereby allowing the piston to be cooled efficiently.

한편, 상기 전자제어유닛(50)은 메인갤러리의 압력이 낮을 경우, 상기 진공조절부(40)를 통해 액추에이터(30)로 공급되는 진공량을 차단시키게 되는 바,On the other hand, the electronic control unit 50, when the pressure of the main gallery is low, bar the amount of vacuum supplied to the actuator 30 through the vacuum control unit 40,

상기 액추에이터(30)에서는 제 2 유로(15)를 통해 연결된 오일유량 조절밸브(20)를 닫게 되고, 이에따라 오일펌프(13)를 통해 오일젯(12)으로는 오일공급이 전혀 이루어지지 않게 된다.In the actuator 30, the oil flow rate control valve 20 connected through the second flow path 15 is closed. Accordingly, no oil is supplied to the oil jet 12 through the oil pump 13.

다시말해, 본 발명은 엔진회전수가 1000∼2000RPM인 저속구간에서 오일젯(12)으로 오일펌프(13)의 오일이 공급되는 것을 차단하였는 바, 메인베어링과 콘로드 베어링의 사이에 최소 유막이 형성되는 것을 방지함은 물론, 크랭크 샤프트와 베어링의 마모가 발생하는 것을 차단할 수 있게 되는 것이다.In other words, the present invention prevents the oil of the oil pump 13 from being supplied to the oil jet 12 in a low speed section having an engine speed of 1000 to 2000 RPM, and a minimum oil film is formed between the main bearing and the cone rod bearing. Of course, it is possible to prevent the wear of the crankshaft and the bearing, as well as to prevent.

이상에서 설명한 바와같이 본 발명은 진공압을 이용하여 오일젯의 오일 분사량을 효율적으로 제어함으로써, 차량의 저속 주행시와 오일의 저온시에 오일젯을 통한 오일의 분사가 효율적으로 이루어져 메인베어링과 콘로드의 베어링에 대한 윤활이 원활하게 이루어지지 못하면서 마모 및 소착이 발생되는 문제를 개선할 수 있도록 함은 물론, 엔진의 출력 저하 및 배기가 악화되는 것을 방지하는 효과를 얻을 수 있게 되는 것이다.As described above, the present invention efficiently controls the oil jet amount of the oil jet by using the vacuum pressure, so that the oil jet is efficiently injected through the oil jet at low speed of the vehicle and at low temperature of the oil. The lubrication of the bearings can not be made smoothly to improve the problem of wear and seizure, as well as to prevent the deterioration of the engine output and exhaust is deteriorated.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와같은 변경은 청구범위 기재의 범위내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims.
