본 발명에 따른 구성은 제 1 도에 도시한 바와 같이 과급기의 회전수를 감지하는 과급기 회전수센서(11)와, 냉각수 온도를 감지하는 냉각수온 센서(12)와, 시동상태를 감지하는 시동키(13)와, 이들 센서(11)(12)(13)에 의해서 엔진의 시동상태 및 냉각수의 온도와 과급기의 회전수를 감지하고 윤활유를 순환시키기위한 릴레이(RY)와 솔레노이드 밸브(SV)를 구동시키는 엔진 전자제어장치(15)와, 이 엔진 전자제어장치(15)에서 출력되는 구동신호를 인가받아 오일탱크(20)와 과급기 사이를 개통시키는 솔레노이드 밸브(SV)와, 이 엔진 전자제어장치(15)에서 출력되는 구동신호를 인가받아 배터리(16)에서 인가되는 전원을 모터(17)에 공급하는 릴레이(RY)와, 이 배터리(16)에서 인가되는 전원을 인가받아 오일펌프(18)를 작동시켜 과급기의 윤활유를 순환시키는 모터(17)를 구성된다.As shown in FIG. 1, the configuration according to the present invention includes a supercharger rotation speed sensor 11 for detecting the rotation speed of the supercharger, a coolant temperature sensor 12 for detecting the coolant temperature, and a ignition key for detecting a starting state. (13) and relays (RY) and solenoid valves (SV) for sensing the engine starting state, the temperature of the coolant and the rotation speed of the supercharger, and circulating the lubricating oil by these sensors (11) (12) (13). An engine electronic controller 15 for driving, a solenoid valve SV for opening the oil tank 20 between the supercharger by receiving a drive signal output from the engine electronic controller 15, and the engine electronic controller The oil pump 18 receives the driving signal output from the 15 and supplies the power applied from the battery 16 to the motor 17 and the power applied from the battery 16. The motor 17 to circulate the lubricant of the supercharger It is made.

제 2 도는 본 발명의 동작상태를 보인 흐름도로서, 시동키 입력을 확인하는 단계와, 시동키 작동시 냉각수 온도를 감지하는 단계와, 이 냉각수 온도가 소정온도 이상인지를 확인하는 단계와, 소정온도 이하시 모터(17)를 작동시켜 베어링 케이스 내에 충진되어 있는 윤활유를 순환시키는 단계를 수행함을 보이고 있다. 특히, 과급기 회전수센서(11)에 의해 감지되는 과급기의 회전수에 비례하게 모터(17)의 회전속도를 조절한다.2 is a flowchart showing an operating state of the present invention, the method comprising the steps of: checking a start key input; detecting a coolant temperature when the start key is operated; checking whether the coolant temperature is above a predetermined temperature; Hereinafter, the motor 17 is operated to circulate the lubricating oil filled in the bearing case. In particular, the rotation speed of the motor 17 is adjusted in proportion to the rotation speed of the supercharger detected by the supercharger rotation speed sensor 11.

이와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.

시동키(13)의 조작상태를 감지(S21)한 엔진 전자제어장치(15)는 시동키(13)가 "온" 상태로 절환되었을 때 냉각수온 센서(12)에 의해 감지되는 냉각수의 온도를 감지한다(S22). 그리고 냉각수 온도가 소정온도까지 상승되었는지를 확인한다. 즉 엔진 전자제어장치(15)는 냉각수 온도에 의해 엔진의 워밍업 상태를 판정하고, 엔진이 완전히 워밍업되지 않았으면 릴레이(RY)를 "온" 상태를 절환하고, 솔레노이드 밸브(SV)를 개통시킨다. 이에따라 배터리(16)에서 출력되는 전원이 모터(17)를 구동시켜 오일펌프(18)가 구동하게 되고, 이에 연동하여 오일탱크(20)에 충진되어 있는 오일이 오일펌프(18)와 솔레노이드 밸브(SV)를 경유하여 과급기에 공급된다. 그리고 기존에 과급기에 충진되어 있는 윤활유는 다시 오일탱크(20)로 재 순환되어진다. 이때 엔진 전자제어장치(15)는 과급기 회전수센서(11)에 의해 감지되는 과급기의 회전수에 비례하게 모터(17)의 회전속도를 조절한다(S24)(S25).The engine electronic controller 15 that detects the operating state of the starter key 13 (S21) is configured to determine the temperature of the coolant detected by the coolant temperature sensor 12 when the starter key 13 is switched to the "on" state. Sense (S22). Then, it is checked whether the coolant temperature is raised to a predetermined temperature. In other words, the engine electronic controller 15 determines the warm-up state of the engine based on the coolant temperature. If the engine is not completely warmed up, the engine electronic controller 15 switches the relay RY "on" state and opens the solenoid valve SV. Accordingly, the power output from the battery 16 drives the motor 17 to drive the oil pump 18, and the oil filled in the oil tank 20 interlocks with the oil pump 18 and the solenoid valve ( It is supplied to the supercharger via SV). And the lubricating oil which is filled in the existing supercharger is recycled back to the oil tank (20). At this time, the engine electronic controller 15 adjusts the rotation speed of the motor 17 in proportion to the rotation speed of the supercharger detected by the supercharger rotation speed sensor 11 (S24) (S25).

오일탱크(20)에 충진되어 있는 윤활유를 과급기에 베어링 케이스 내에 순환시키면서 엔진 전자제어장치(15)는 냉각수온 센서(12)에 의해 감지되는 냉각수의 온도가 소정온도에 이르면, 엔진 전자제어장치(15) 즉 엔진의 위밍업이 끝나면 엔진 전자제어장치(15)는 릴레이(RY)를 "오프" 상태로 절환하고, 이어서 모터(17)를 정지시켜 윤활유의 순환동작을 정지시킨다.While circulating the lubricating oil filled in the oil tank 20 in the bearing case in the supercharger, the engine electronic controller 15 may determine that the temperature of the coolant detected by the coolant temperature sensor 12 reaches a predetermined temperature. 15) That is, when the engine is finished warming up, the engine electronic controller 15 switches the relay RY to the " off " state, and then stops the motor 17 to stop the circulating operation of the lubricating oil.

바람직하게는 고속 운행직후 즉, 운전자가 시동키(13)를 조작하여 "오프" 상태로 절환한 후 소정시간 동안 위에서 같이 릴레이(RY)를 "온" 상태를 절환하고, 솔레노이드 밸브(SV)를 개통시킨다. 이에 따라 배터리(16)에서 출력되는 전원이 모터(17)를 구동시켜 오일펌프(18)가 구동하게 되고, 이에 연동하여 오일탱크(20)에 충진되어 있는 오일이 오일펌프(18)와 솔레노이드 밸브(SV)를 경유하여 과급기에 공급된다. 그리고 기존에 과급기에 충진되어 있는 윤활유는 다시 오일탱크(20)로 재순환되어진다. 이에따라 과급기의 냉각시간이 단축되어 과열로 인한 과급기의 손상을 줄일 수 있는 것이다.Preferably, immediately after the high-speed operation, that is, the driver switches the "off" state by operating the start key 13, the relay RY is switched "on" state as above for a predetermined time, and the solenoid valve SV is turned on. Open it. Accordingly, the power output from the battery 16 drives the motor 17 to drive the oil pump 18, and the oil filled in the oil tank 20 interlocks with the oil pump 18 and the solenoid valve. It is supplied to the supercharger via SV. And the lubricating oil which has been filled in the supercharger is recycled back to the oil tank (20). Accordingly, the cooling time of the supercharger is shortened, thereby reducing the damage of the supercharger due to overheating.

이상에서와 같이 본 발명은 시동직후부터 엔진의 워밍업이 끝나기전까지, 혹은 고속 주행후 소정시간동안 과급기의 베어링 케이스 내에 윤활유를 순환시킴으로써, 엔진 시동후 워밍업되기를 기다리지 않고도 차량을 구동할 수 있으며, 또한 시동직후 초기 급가속으로 인한 과급기의 손상을 방지할 수 있으며, 나아가서는 시도초기 급가속이 가능하므로 에어탱크의 충전시간을 단축할 수 있다. 또한 본 발명은 겨울철 시동초기 급가속이 가능함으로 아이들 RPM의 안정화가 빠를 뿐만 아니라 고속주행후 과급기의 냉각시간을 단축함으로써 과급기의 손상을 방지할 수 있는 것이다.As described above, the present invention can drive the vehicle without waiting for warm-up after starting the engine by circulating the lubricating oil in the bearing case of the supercharger immediately after starting the engine until the end of the warm-up of the engine or for a predetermined time after the high-speed driving. It is possible to prevent damage to the supercharger due to the initial rapid acceleration immediately, and furthermore, it is possible to shorten the charging time of the air tank since the initial rapid acceleration is possible. In addition, the present invention is capable of preventing the damage to the supercharger by the rapid acceleration of the start-up in winter, as well as the fast stabilization of the idle RPM and shortening the cooling time of the supercharger after the high-speed driving.
