본 발명은 차량 엔진의 오일공급장치에 관한 것으로, 차량 시동시 충분히 예열되어진 오일이 엔진의 각 습동부로 공급되도록 하여, 동절기에 크게 발생되는 엔진 각 습동부의 마모발생이 가능한 한 억제되도록 하는 차량 엔진의 오일공급장치에 관한 것이다.The present invention relates to an oil supply device for a vehicle engine, and is provided so that oil, which is sufficiently preheated when the vehicle is started, is supplied to each sliding part of the engine, so that wear occurrence of each sliding part of the engine that occurs largely in winter is suppressed as much as possible. The oil supply device of the engine.

주지된 바와 같이, 마모가 크게 발생되는 차량 엔진의 습동부에는 엔진 구동에 따라 오일이 연속적으로 공급되도록 하여 습동부의 마모가 가능한 한 억제되도록 하고 있는데, 종래 오일공급장치는, 도 1에 도시된 바와 같이, 엔진의 하부에 설치되어, 엔진 내부의 오일이 회수되어 저장되는 오일팬(20)과 ; 메인 오일라인(L)에 설치되어, 오일팬(20)으로부터 공급되는 오일에 함유되어진 이물질들을 제거하는 오일필터(40) ; 메인 오일라인(L)에 설치되어, 오일팬(20)에 저장되어진 오일을 메인 오일라인(L)을 따라서 엔진의 메인 오일갤러리(12)로 강제적으로 공급하는 오일펌프(50) 및; 엔진에 설치되어, 메인 오일라인(L)을 통해서 공급되는 오일을 각 습동부로 분배하는 메인 오일갤러리(12)를 갖춘 구조로 되어 있다.As is well known, oil is continuously supplied to a sliding part of a vehicle engine in which wear is largely generated in accordance with engine driving so that wear of the sliding part is suppressed as much as possible. The conventional oil supply device is illustrated in FIG. 1. As described above, the oil pan 20 is installed at the lower part of the engine to recover and store oil in the engine; An oil filter 40 installed in the main oil line L to remove foreign substances contained in the oil supplied from the oil pan 20; An oil pump 50 installed in the main oil line L and forcibly supplying the oil stored in the oil pan 20 to the main oil gallery 12 of the engine along the main oil line L; Installed in the engine, it is a structure having a main oil gallery 12 for distributing oil supplied through the main oil line (L) to each sliding part.

따라서, 오일펌프(50)에 의해서 오일팬(20)의 오일이 메인 오일라인(L)을 따라서 메인 오일갤러리(12)로 강제적으로 공급되고, 메인 오일갤러리(12)로 공급되어진 오일은 경사지게 배치되어진 메인 오일갤러리(12)를 따라서 이동되면서 메인 오일갤러리(12)에 연결되어진 각 습동부 라인으로 자유로이 유입되는데, 일예로 메인 오일갤러리(12)의 오일이 각 메인 베어링(33)과 크랭크저널(31) 사이로 유입된후, 크랭크축(도시안됨)과 크랭크핀(32) 사이로 유입되고, 이후 자유낙하하여 엔진 하부에 설치된 오일팬(20)으로 회수되어, 상기 경로를 통해서 재순환하게 된다.Accordingly, the oil of the oil pan 20 is forcibly supplied to the main oil gallery 12 along the main oil line L by the oil pump 50, and the oil supplied to the main oil gallery 12 is inclinedly disposed. While moving along the main oil gallery (12), freely flows into each sliding line connected to the main oil gallery (12). For example, the oil of the main oil gallery (12) is the main bearing (33) and the crank journal ( 31) and then flows between the crankshaft (not shown) and the crank pin 32, and then free-falls and is recovered to the oil pan 20 installed in the lower engine, and recycled through the path.

When the piston 110 is moved toward the outlet of the oil storage tank 60 by the air pressure from the air tank 70, the inlet of the oil storage tank 60 communicated with the first auxiliary oil line L1 is the piston ( Blocked by 110, the oil stored in the oil storage tank 60 is supplied to the main oil line (L) through the second auxiliary oil line (L3), while the air tank (70) by the solenoid valve (91) When the air pressure from the) is blocked, the piston 110 is returned to the initial position by the restoring force of the spring, the inlet of the oil storage tank 60 is opened, the oil storage tank 60 and the main oil line (L) It is communicated by the 1st auxiliary oil line L1.

본 발명에 따른 오일공급장치의 작동상태를 개략적으로 설명해 보면, 우선 운전자가 엔진을 구동시키기 위해서 키스윗치를 제2단으로 조작하게 되면, 제어수단(80)에서 외부 온도를 감지하여 오일예열 작동유무를 판단하게 된다.When the operating state of the oil supply device according to the present invention is described schematically, first, when the driver operates the kiss switch in the second stage to drive the engine, the control unit 80 senses the external temperature to detect whether the oil is preheated or not. Will be judged.

만일, 외부 온도가 설정 온도 이상이면, 솔레노이드밸브(91,92)가 닫혀진 상태에서 예열수단(100)으로의 전원이 차단되고, 예열표시수단(120)이 작동정지된 상태로 유지되도록 하여, 운전자가 예열이 필요없다는 것을 인식할 수 있게 된다. 따라서, 키스윗치가 제2단으로 조작되더라도 예열표시수단(120)이 작동되지 않으면, 키스윗치를 즉시 제3단(시동위치)으로 조작하여 엔진을 시동시킨다. 이때, 엔진 오일은 윤활기능을 만족스럽게 수행할 수 있는 상태이므로, 엔진의 각 습동부로의 오일공급이 원활하게 수행되어 이들 각 습동부의 마모발생은 가능한 한 억제된다. 이러한 상태에서의 오일 경로를 순차적으로 설명해 보면, 오일팬(20)에 저장되어진 오일이 오일팬(20) → 오일필터(40) → 오일펌프(50) → 메인 오일갤러리(12)로 공급된 후, 각 습동부 라인으로 분배되어, 메인 베이링(33)과 크랭크저널(31) 사이, 크랭크축(도시안됨)과 크랭크핀(32) 사이를 거쳐서 자유낙하되어 오일팬(20)으로 회수된다.If the external temperature is higher than or equal to the set temperature, the power to the preheating means 100 is cut off while the solenoid valves 91 and 92 are closed, and the preheating display means 120 is maintained in an operation stopped state, so that the driver Will recognize that no preheating is required. Therefore, if the preheat display means 120 is not operated even when the key switch is operated in the second stage, the key switch is immediately operated to the third stage (starting position) to start the engine. At this time, since the engine oil is in a state capable of satisfactorily performing a lubrication function, the oil supply to each sliding part of the engine is smoothly performed, and the occurrence of wear of each of the sliding parts is suppressed as much as possible. When the oil path in this state is described sequentially, after the oil stored in the oil pan 20 is supplied to the oil pan 20 → oil filter 40 → oil pump 50 → main oil gallery 12, And distributed to each sliding part line, and are freely dropped between the main bearing 33 and the crank journal 31 and between the crank shaft (not shown) and the crank pin 32 to be recovered to the oil pan 20.

반면, 외부 온도가 설정 온도보다 낮으면, 솔레노이드밸브(91,92)가 닫혀진 상태에서 예열수단(100)으로 전원이 공급되어 오일저장탱크(60)에 저장되어진 오일이 예열되면서, 예열표시수단(120)이 작동되어, 운전자가 예열중이라는 것을 인식하게 된다. 이후, 오일저장탱크(60)의 오일이 예열수단(100)에 의해 소정 온도로 가열되면, 솔레노이드밸브(91,92)가 오픈되면서, 공기탱크(70)로부터의 공기압에 의해 피스톤(60)이 하방향으로 밀리게 되어, 오일저장탱크(60)의 유입구가 닫혀지면서, 오일저장탱크(60)의 오일이 제2보조 오일라인(L2)을 통해서 메인 오일라인(L)으로 공급된 후에 메인 오일갤러리(12)로 유입되어, 엔진 각 습동부에 예열된 오일이 공급된다. 이후, 예열수단(100)으로의 전원공급이 차단되면서 예열표시수단(120)이 작동정지된다. 따라서, 키스윗치를 제2단으로 조작했을 때, 예열표시수단(120)이 작동되면 운전자는 예열표시수단(120)이 작동정지될 때 까지(오일이 예열될 때까지) 잠시 기다린 후, 예열표시수단(120)이 작동정지된 상태에서 키스윗치를 제3단으로 조작하여 엔진을 시동시킨다. 이러한 경우, 엔진이 시동되더라도 각 습동부에는 고온으로 예열되어진 엔진오일이 공급되므로, 엔진의 각 습동부가 크게 마모되는 것이 가능한 한 억제된다.On the other hand, if the external temperature is lower than the set temperature, the power is supplied to the preheating means 100 in a state in which the solenoid valves 91 and 92 are closed to preheat the oil stored in the oil storage tank 60, 120 is activated to recognize that the driver is warming up. Thereafter, when the oil in the oil storage tank 60 is heated to a predetermined temperature by the preheating means 100, the solenoid valves 91 and 92 are opened, and the piston 60 is opened by the air pressure from the air tank 70. It is pushed downward, the inlet of the oil storage tank 60 is closed, the main oil after the oil of the oil storage tank 60 is supplied to the main oil line (L) through the second auxiliary oil line (L2) Flowed into the gallery 12, preheated oil is supplied to each sliding part of the engine. Thereafter, while the power supply to the preheating means 100 is cut off, the preheating display means 120 is stopped. Therefore, when the preheat display means 120 is operated when the key switch is operated in the second stage, the driver waits for a while until the preheat display means 120 is deactivated (until the oil is preheated) and then displays the preheat indication. In the state in which the means 120 are stopped, the key switch is operated in the third stage to start the engine. In this case, since the engine oil preheated to high temperature is supplied to each sliding part even if an engine starts, it is suppressed as much as possible that each sliding part of an engine wears large.

한편, 엔진이 시동된 상태에서 냉각수의 온도가 설정 온도보다 낮게 되면, 예열수단(100)으로 전원이 인가되면서 예열표시수단(120)이 작동되고, 열려진 솔레노이드밸브(91,92)중에서 공기압 라인의 솔레노이드밸브(91)만이 닫혀지게 되는데, 이와 같이 솔레노이드밸브(91)가 닫혀지면 솔레노이드밸브(92)가 개방된 상태에서 스프링의 복원력에 의해 피스톤(110)이 초기위치로 복귀되어 오일저장탱크(60)의 유입구가 개구되므로, 오일펌프(50)로부터의 오일중 일부는 메인 오일라인(L)을 통해서 메인 오일갤러리(12)로 유동되면서, 나머지 일부는 제1보조 오일라인(L1)으로 유입되어 오일저장탱크(60)를 통과하면서 예열수단(100)에 의해 가열된 후에 제2보조 오일라인(L2)을 통해서 메인 오일라인(L)으로 유입되어 메인 오일갤러리(12)로 유동된다. 이후, 엔진 구동이 소정 시간동안 지속되어서 엔진이 충분히 가열되어, 냉각수의 온도가 설정 온도 이상으로 되면, 예열수단(100)으로의 전원공급이 차단되면서 예열표시수단(120)이 작동정지되고, 제2보조 오일라인(L2)의 솔레노이드밸브(92)가 닫혀지게 되어, 오일저장탱크(60)에 오일이 보충되고, 메인 오일갤러리(12)로의 오일공급은 메인 오일라인(L)을 통해서만 이루어진다.On the other hand, when the temperature of the coolant is lower than the set temperature while the engine is started, the preheat display means 120 is operated while the power is supplied to the preheating means 100, and the air pressure line of the solenoid valves 91 and 92 is opened. Only the solenoid valve 91 is to be closed. When the solenoid valve 91 is closed in this way, the piston 110 is returned to the initial position by the restoring force of the spring in the state in which the solenoid valve 92 is opened. Since the inlet of the opening is opened, some of the oil from the oil pump 50 flows through the main oil line L to the main oil gallery 12, while the other part flows into the first auxiliary oil line L1 to be oil. After being heated by the preheating means 100 while passing through the storage tank 60, it flows into the main oil line L through the second auxiliary oil line L2 and flows to the main oil gallery 12. Thereafter, when the engine is driven for a predetermined time and the engine is sufficiently heated, and the temperature of the cooling water is higher than the set temperature, the preheating display means 120 is stopped while the power supply to the preheating means 100 is cut off. The solenoid valve 92 of the secondary oil line (L2) is closed, the oil is replenished in the oil storage tank 60, the oil supply to the main oil gallery (12) is made only through the main oil line (L).

이상 상기한 바와 같은 본 발명에 따르면, 동절기 등과 같이 외부 온도가 낮은 상태에서 엔진을 시동하더라도, 예열수단에 의해 적절하게 예열되어진 오일이 엔진 각 습동부로 공급되므로, 이들 각 습동부의 마모발생이 가능한 한 억제되어, 엔진 수명이 연장되는 효과가 있다.According to the present invention as described above, even if the engine is started in a state of low external temperature, such as winter, oil preheated by the preheating means is supplied to the engine sliding parts, the wear occurs in each of the sliding parts It is suppressed as much as possible, and there exists an effect of extending an engine life.
