Abstract

PURPOSE: An engine oil consumption reducer is provided to prevent the waste of engine oil and the increase of exhaust gas by separating the oil in blow-by gas and burning pure blow-by gas. CONSTITUTION: A cam(2) and a camshaft(3) are received in a rocker cover(1), and a blower fan(4) rotating with the camshaft is installed at one end of the camshaft. One end of a breather hose(5) is connected to the wall face of the rocker cover while the other end of the breather hose is connected to an intake manifold(6). A metal net(7) is installed in the rocker cover. Blow-by gas leaking to a crank case through a gap between a piston and a cylinder flows into the rocker cover. Engine oil is supplied to the contacting part of the rocker arm and a valve stem for the prevention of wear. Upon the lift-down of the piston, mixed gas flows into the cylinder and blow-by gas in the rocker cover flows into a combustion chamber via the intake manifold. When the camshaft rotates, blow-by gas flows to the breather hose. Then, oil grows to a large flow particulate and falls down to the bottom of the rocker cover. Thereafter, blow-by gas without oil mist moves to the intake manifold through the breather hose.

Description

엔진 오일 소모 저감 장치{Engine oil waste decreasing apparatus}Engine oil waste reducing apparatus

본 발명은 캠샤프트의 회전력을 이용한 엔진 오일 소모 저감 장치에 관한 것이다.The present invention relates to an engine oil consumption reduction device using the rotational force of the camshaft.

연소실내에서 폭발된 연소가스 또는 압축 행정을 통해 압축된 가스는 매우고압이므로 그의 일부가 피스톤링과 실린더 내벽면과의 틈새를 통하여 크랭크케이스로의 누설이 일어난다.The combustion gas exploded in the combustion chamber or the gas compressed through the compression stroke is very high pressure, so a part thereof leaks into the crankcase through a gap between the piston ring and the inner wall of the cylinder.

이와같이 크랭크 케이스에 모아진 블로바이가스는 통상 연료 탱크내에서 발생된 연료증발가스와 함께 블로바이가스 환원장치(P.C.V)에 의해 로커카바내로 들어간 후 다시 브리더호스를 통하여 흡기매니폴드로 유입된 후 연소실로 들어가 연소시키므로써 블로바이가스의 외부 방출로 인한 대기 오염을 방지토록하고 있다.As such, the blow-by gas collected in the crankcase enters the rocker cover by the blow-by gas reducing device (PCV) together with the fuel evaporation gas generated in the fuel tank, and then flows into the intake manifold through the breather hose and then into the combustion chamber. By entering and burning, it prevents air pollution due to the external release of blowby gas.

실린더헤드 상부에 설치된 로커카바내에는 흡배기 밸브를 작동시키기 위한 캠축과 캠 및 로커암등이 밸브 작동 기구가 설치되어 있으며, 밸브 작동시 운동 부분에의 마모를 방지하기 위하여 오일이 공급되기 때문에 오일 및 블로바이 가스의 누설 방지를 위해 시일 구조를 채택하고 있다.In the rocker cover installed above the cylinder head, the camshaft, cam and rocker arm for operating the intake / exhaust valve are installed with valve operation mechanism.Oil is supplied because oil is supplied to prevent abrasion to the moving part during valve operation. The seal structure is adopted to prevent the leakage of blow-by gas.

이에따라 브리더호스를 통해 연소실로 유입되는 블로바이가스 속에는 오일이 함유되기 때문에 종래의 경우 미연소가스인 블로바이 가스와 함께 오일의 연소도 피할 수 없어 오일의 과도한 소모를 가져오고 대기 오염을 악화시키게 되는 원인이 되고 있다.Accordingly, since the oil is contained in the blow-by gas flowing into the combustion chamber through the breather hose, the combustion of the oil together with the blow-by gas, which is unburned gas, is unavoidable, causing excessive consumption of oil and worsening air pollution. It is the cause.

이에 본 발명은 상기한 점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 로커카바로부터 연소실로 유입되는 블로바이가스속에 포함된 오일을 분리하여 순수한 블로바이 가스만 연소시켜 배출하므로써 오일의 소모 및 배기가스 악화를 방지하는 엔진오일 소모 저감 장치를 제공하는 데 있다.Therefore, the present invention has been proposed in view of the above, and its object is to separate oil contained in the blowby gas flowing into the combustion chamber from the rocker cover and burn only the pure blowby gas to discharge, thereby depleting oil consumption and exhaust gas. It is to provide an engine oil consumption reduction device that prevents.

상기한 목적을 달성하기 위하여 본 발명은 밸브를 작동하기 위한 캠축등을 보호하기 위하여 실린더 헤드 상부에 장착된 로커카바와, 그 로커카바내에 수집된 블로바이가스를 흡기매니폴드측으로 안내하는 브리더호스를 포함하는 장치에 있어서, 상기 캠축의 일단에는 타단측으로 공기를 송풍하는 팬이 장착되어 있으며, 상기 브리더 호스는 상기 팬이 장착된 방향과 대향되는 반대측의 로커카바에 접속되고 브리더호스의 접속 지점 가까이의 로커카바 내에는 가는 눈목을 갖는 금속망이설치되어 있는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a rocker cover mounted on an upper portion of a cylinder head to protect a camshaft for operating a valve, and a breather hose for guiding blow-by gas collected in the rocker cover to the intake manifold side. In a device comprising: a fan for blowing air to the other end is mounted at one end of the camshaft, the breather hose is connected to the rocker cover on the opposite side opposite to the direction in which the fan is mounted and near the connection point of the breather hose. The rocker cover is characterized in that a metal mesh having a narrow eye is installed.

이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 의한 엔진 오일 소모 저감 장치를 나타내는 도면으로 도면중 부호 1은 실린더 헤드 상부에 장착된 로커카바이다.1 is a view showing an engine oil consumption reduction apparatus according to the present invention, wherein 1 is a rocker cover mounted on an upper portion of a cylinder head.

로커카바(1)내에는 흡배기 밸브를 작동하기 위한 캠(2)과 캠축(3)등의 밸브작동기구가 수용되어 있으며, 캠축(3)의 일단에는 캠축(3)의 회전에 의해 함께 회전하여 공기를 송풍하는 팬(4)이 장착되어 있다.In the rocker cover 1, a valve operating mechanism such as a cam 2 and a camshaft 3 for operating an intake / exhaust valve is accommodated. At one end of the camshaft 3, the camshaft 3 rotates together with the cam shaft 3 to rotate. The fan 4 which blows air is attached.

팬(4)이 장착된 캠축(3)의 타단의 로커카바(1) 벽면에는 브리더호스(5)의 일단이 접속되고, 브리더호스(5)의 타단은 흡기매니폴드(6)에 접속되어 있다.One end of the breather hose 5 is connected to the wall surface of the rocker cover 1 of the other end of the camshaft 3 on which the fan 4 is mounted, and the other end of the breather hose 5 is connected to the intake manifold 6. .

그리고 브리더호스(5)가 접속되는 입구의 로커카바내에는 가는 눈목(Mesh)의 금속망(7)이 설치되어 있다.In the rocker cover at the entrance to which the breather hose 5 is connected, a fine mesh metal mesh 7 is provided.

이와같은 본 발명 구성에 의한 작용을 설명하면 다음과 같다.Referring to the operation by the configuration of the present invention as follows.

엔진이 시동되면 크랭크축으로부터 V벨트 전동장치를 통해 회전력을 전달받은 캠축(3)이 회전하므로써 캠(2)에 의해 로커아암을 작동시켜 흡배기 밸브를 개폐하게 된다.When the engine is started, the camshaft 3, which receives the rotational force from the crankshaft through the V-belt transmission, rotates to operate the rocker arm by the cam 2 to open and close the intake and exhaust valves.

압축과정중에 피스톤과 실린더와의 틈새를 통해 크랭크 케이스로 누설된 블로바이 가스는 도시하지 아니한 블로바이 가스 환원 장치를 통해 로커카바(1)내로 유입되어지게 된다.The blow-by gas leaked into the crankcase through the gap between the piston and the cylinder during the compression process is introduced into the rocker cover 1 through a blow-by gas reducing device (not shown).

한편, 캠과 로커아암, 로커아암과 밸브스템의 접촉부에는 마모방지를 위해엔진 오일이 공급된다.On the other hand, the engine oil is supplied to the cam and the rocker arm, the contact between the rocker arm and the valve stem to prevent wear.

이 상태에서 흡기밸브가 열리고 피스톤이 하강 작동하게 되면 흡기 부압이 작용하여 혼합기가 실린더내로 유입되어지게 되는데, 이때 흡기 부압에 의해 블리더호스(5)를 통해 로커카바(1)내의 블로바이가스가 흡기매니폴드(6)로 유입되어 함께 연소실로 들어가게 된다.In this state, when the intake valve is opened and the piston is lowered, the intake negative pressure is applied, and the mixer is introduced into the cylinder. It enters the intake manifold 6 and enters the combustion chamber together.

한편 캠축(3)이 회전하면 이에 연동하여 팬(4)이 회전하면서 로커카바(1)내의 블로바이가스가 브리더호스(5)측으로 송풍하게 되는데 가스와 오일의 비중이 크게 다르므로 가스는 신속히 이동하게 되는 반해 오일은 철망(7)쪽으로 밀림 현상에 의해 서서히 이동하여 서로 뭉침 현상이 일어나게 되면서 큰 유립으로 성장하게 된다. 큰 유립으로 성장한 오일미스트는 최종적으로 철망(7)에 의해 걸러져 달라붙으면서 점차 크기가 성장하여 로커카바(1) 바닥으로 떨어지게 되고 오일미스트가 제거된 블로바이가스는 브리더호스(5)를 통해 흡기매니폴드(6)로 이동하게 되는 것이다.On the other hand, when the camshaft 3 rotates, the fan 4 rotates in conjunction with this, and the blow-by gas in the rocker cover 1 blows to the breather hose 5 side, and since the specific gravity of the gas and oil is greatly different, the gas moves quickly. On the other hand, the oil is gradually moved by the sliding phenomenon toward the wire mesh (7), the agglomeration phenomenon occurs as it grows into large grains. The oil mist grown in large granules is finally filtered out by the wire mesh (7) and gradually grows in size as it sticks to the bottom of the rocker cover (1), and the blow mist gas from which the oil mist is removed is sucked in through the breather hose (5). It will be moved to the manifold (6).

이상과 같은 본 발명에 의하면 로커카바내 캠축 일단에 팬을 장착하고 브리더호스는 팬의 반대측의 로커카바에 접속토록 하고, 그 접속지점 가까이에 가는 눈목을 가지는 금속망을 설치하는 것에 의해서, 캠축에 의해 회전하는 팬과 금속망의 작용에 의해 블로바이가스 속에 포함된 엔진 오일을 응집시켜 로커카바내에 잔류토록 하므로써 엔진 오일의 불필요한 소모 및 배기가스 악화를 방지하게 되는 효과가 있다.According to the present invention as described above, the fan is mounted on one end of the camshaft in the rocker cover, and the breather hose is connected to the rocker cover on the opposite side of the fan, and the camshaft is installed on the camshaft by installing a metal net having a narrow eye near the connection point. By aggregating the engine oil contained in the blow-by gas by the action of the rotating fan and the metal mesh to remain in the rocker cover, there is an effect of preventing unnecessary consumption of engine oil and deterioration of exhaust gas.
