Description

엔진 오일의 슬러지 시뮬레이터Sludge Simulator of Engine Oil

본 발명은 엔진 오일의 슬러지 시뮬레이터에 관한 것으로서, 특히 엔진 오일이 저온에서 산화되어 생성되는 슬러지의 생성 과정과 이 슬러지 생성에 대한 엔진 오일의 영향을 파악할 수 있도록 한 엔진 오일의 슬러지 시뮬레이터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sludge simulator for engine oil, and more particularly, to a sludge simulator for engine oil, which is capable of grasping the sludge produced by oxidizing the engine oil at low temperature and the influence of the engine oil on the sludge production.

일반적으로 엔진 오일은 제1도에 도시된 바와 같이 로커 커버(7)의 오일 주입구(8)를 통해 오일팬(1)에 저장되고, 이 오일팬(1)에서 엔진 내부의 주요 운동 부분과 마찰 부분에 공급되어 엔진이 원활하게 작동되도록 윤활 및 냉각 작용을 하게된다. 즉, 상기 엔진 오일은 실린더 헤드(2)에 내재된 밸브 기구(3)와 실린더 블록(4)에 내재되는 크랭크 축(5), 피스톤(6), 커넥팅 로드 등에 공급되어 윤활 및 냉각 작용을 하게 된다.In general, the engine oil is stored in the oil pan 1 through the oil inlet 8 of the rocker cover 7, as shown in FIG. 1, and in this oil pan 1 friction with the main moving parts inside the engine. It is supplied to the part to lubricate and cool the engine to operate smoothly. That is, the engine oil is supplied to the valve mechanism (3) inherent in the cylinder head (2) and the crankshaft (5), piston (6), connecting rod, etc., inherent in the cylinder block (4), to provide lubrication and cooling. do.

상기와 같은 엔진 오일은 청정 분산성, 산화 안전성, 마멸 방지성, 녹 방지성, 양호한 점도 특성, 거품 방지성, 베어링 부식 방지성, 연비 향상성 등의 광범위한 성능이 요구된다.Such engine oils require a wide range of performances such as clean dispersibility, oxidation stability, anti-wear, anti-rust, good viscosity characteristics, anti-foaming, anti-corrosion of bearings, fuel efficiency improvement, and the like.

그리고, 엔진 오일이 다른 윤활유와 크게 다른점은 연소실로부터 혼입되는 물질의 영향을 강하게 받게 되는 바, 이것은 연소 가스에서 생성되는 황산이나 염산과 같은 산성 물질, 미연 가스나 슬러지 성분, 카본 등에 영향을 받게 된다. 따라서, 이들이 엔진 오일 속에 중화되어 엔진의 각부에 침적되는 일이 없이 엔진 오일속에 분산되거나 가용화시키는 능력이 요구된다.In addition, the difference between the engine oil and other lubricants is that it is strongly influenced by the material mixed from the combustion chamber, which is affected by acidic substances such as sulfuric acid or hydrochloric acid generated from the combustion gas, unburned gas, sludge components, and carbon. do. Therefore, the ability to disperse or solubilize in the engine oil is required without having them neutralized in the engine oil and deposited on each part of the engine.

특히, 연료의 산화에 의해 생성된 카르보닐기, 수산기 등의 극성기를 포함하는 산화 생성물은 다시 중합, 축합되어 불용분으로 된다. 그리고 이 불용분은 열을 받아 경화되면 와니스가 되고, 또한 납화합물, 그을음, 마멸물, 유분 등이 포함되어 침적되면 슬러지가 된다.In particular, oxidation products containing polar groups such as carbonyl groups and hydroxyl groups produced by oxidation of the fuel are further polymerized and condensed to become insoluble. And this insoluble matter becomes varnish when it receives heat and hardens, and also becomes sludge when it contains and deposits lead compound, soot, abrasives, and oil.

상기한 바와 같이 엔진 오일은 연료, 미연 가스등의 블로바이 가스, 오일의 열화, 엔진의 온도 등의 영향으로 슬러지가 발생되는 바, 이 슬러지는 엔진 오일과 함께 엔진의 각부에 유동되면서 윤활 및 냉각 작용을 방해하게 된다.As described above, sludge is generated due to the influence of the blow-by gas such as fuel and unburned gas, deterioration of oil, temperature of the engine, and the like. Will interfere.

따라서, 엔진 오일에서 산화되어 생성되는 슬러지 생성 과정과 이 슬러지가 엔진 오일의 성능에 미치는 영향을 파악하기 위해 종래에는 시험용 엔진에 직접 엔진 오일을 주입한 후 장시간 엔진을 작동시켜 슬러지의 생성 과정 및 영향 등을 측정하였다.Therefore, in order to understand the sludge generation process that is oxidized in the engine oil and the effect of the sludge on the performance of the engine oil, the process and effect of the sludge generation by operating the engine for a long time after directly injecting the engine oil directly into the test engine. Etc. were measured.

그러나, 상기와 같은 엔진 오일의 슬러지 측정 방법은 시험용 엔진에 엔진 오일을 직접 주입하여 슬러지에 대한 여러 가지 사항을 측정하기 때문에 슬러지 측정 소요 시간이 많이 소요될뿐아니라 슬러지 생성에 대한 독립적인 시험도 어려워지는 문제점이 있다.However, the sludge measuring method of the engine oil as described above is not only time-consuming sludge measurement but also difficult to test the sludge because it is a lot of time to measure the sludge by injecting the engine oil directly to the test engine. There is a problem.

따라서, 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 엔진의 블로바이 가스와 동일한 혼합 가스를 생성시키고 이 혼합 가스를 온도 조절이 가능한 오일 탱크에 유입시켜 슬러지를 생성시킴으로써 엔진 오일에서 슬러지 생성 과정과 슬러지의 영향 등을 파악하는데 보다 용이해지도록 한 엔진 오일의 슬러지 시뮬레이터를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, to produce sludge in the engine oil by generating the same mixed gas as the blow-by gas of the engine and flowing the mixed gas into a temperature-controlled oil tank to produce sludge It is to provide a sludge simulator for engine oil that makes it easier to understand the process and the effects of sludge.

Characterized in that consisting of a heating chamber for heating the All.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

본 발명에 의한 엔진 오일의 슬러지 시뮬레이터는 제2도에 도시된 바와 같이 연료와 질소를 혼합시켜 질소 산화물 및 미연 가스를 발생시키는 전기 반응 히터(51)와, 상기 전기 반응 히터(51)의 후방에 위치되고 일산화 질소 및 공기를 혼입시켜 전기 반응 히터(51)에서 발생된 가스를 엔진의 블로바이 가스와 동일한 혼합가스로 만드는 블로 가스 발생기(52)와, 상기 블로 가스 발생기(52) 후방에 설치되어 상기 혼합 가스가 유입되고 미리 저장된 엔진 오일과 섞여 슬러지를 생성시키는 혼합 오일 탱크(53)와, 상기 혼합 오일 탱크(53) 내의 혼합 가스와 엔진 오일을 섞어주는 교반기(60)와, 상기 혼합 오일 탱크(53)내의 오일 온도를 조절토록 혼합 오일 탱크를 가열하는 히팅 챔버(55)로 구성되어 있다.The sludge simulator of the engine oil according to the present invention includes an electric reaction heater 51 which generates nitrogen oxides and unburned gas by mixing fuel and nitrogen, as shown in FIG. 2, and behind the electric reaction heater 51. A blow gas generator 52 which is positioned and mixes nitrogen monoxide and air to make the gas generated by the electric reaction heater 51 into the same mixed gas as the blow-by gas of the engine, and is provided behind the blow gas generator 52. A mixed oil tank 53 into which the mixed gas is introduced and mixed with the pre-stored engine oil to generate sludge, an agitator 60 mixing the mixed gas and the engine oil in the mixed oil tank 53, and the mixed oil tank It consists of the heating chamber 55 which heats the mixed oil tank so that the oil temperature in 53 may be adjusted.

그리고, 상기 교반기(60)는 전동 모터(61)와, 상기 전동 모터(61)에 의해 혼합 오일 탱크(53)내에서 회전되는 팬(62)으로 이루어져 있다.The stirrer 60 includes an electric motor 61 and a fan 62 rotated in the mixed oil tank 53 by the electric motor 61.

상기와 같이 구성되는 본 발명에 따른 엔진 오일의 슬러지 시뮬레이터의 작용을 설명하면 다음과 같다.Referring to the operation of the sludge simulator of the engine oil according to the present invention configured as described above are as follows.

연료와 질소를 전기 반응 히터(51)의 내부를 순환시키면 높은 열에 의한 반응에 의해 연료가 분해되면서 질소와 혼합되므로 질소 산화물 및 미연 가스를 생성시키게 된다.When the fuel and nitrogen are circulated inside the electric reaction heater 51, the fuel is decomposed by the reaction by high heat and mixed with the nitrogen, thereby generating nitrogen oxide and unburned gas.

이렇게 발생된 질소 산화물 및 미연 가스가 블로 가스 발생기(52)로 유입되면, 여기에서는 공기와 질소 등이 혼입되어 엔진의 블로바이 가스와 거의 동일한 성분을 갖는 혼합 가스가 생성된다.When nitrogen oxide and unburned gas generated in this way flow into the blow gas generator 52, air, nitrogen, etc. are mixed here, and the mixed gas which has a component substantially similar to the blow-by gas of an engine is produced | generated.

이와 같이 전기 반응 히터(51)와 블로 가스 발생기(52)를 통해 생성된 혼합가스가 혼합 오일 탱크(53)에 유입되는 데, 이 혼합 오일 탱크(53)는 히팅 챔버(55)에 의해 가열된 상태로 있게 되어 오일 온도가 상승되므로 혼합 가스가 교반기(60)에 의해 오일속에 섞이게 되면 오일이 질화되면서 슬러지가 생성되게 된다.In this way, the mixed gas generated through the electric reaction heater 51 and the blow gas generator 52 flows into the mixed oil tank 53, which is heated by the heating chamber 55. Since the oil temperature is raised to be in a state, when the mixed gas is mixed in the oil by the stirrer 60, the oil is nitrified and sludge is produced.

따라서, 엔진 오일의 슬러지 생성은 엔진 오일의 종류, 오일의 온도, 혼합 가스량 등에 따라 달라지므로 조건을 변화시키면서 슬러지 생성 과정을 측정할 수 있게 된다.Therefore, the sludge generation of the engine oil depends on the type of engine oil, the temperature of the oil, the amount of gas mixture, etc., so that the sludge generation process can be measured while changing the conditions.

상기와 같이 구성되고 작용하는 본 발명에 의한 엔진 오일의 슬러지 시뮬레이터는 블로바이 가스와 동일한 혼합 가스와 일정한 오일 온도를 생성시켜 혼합시킴으로써 슬러지를 발생시키기 때문에 엔진 오일의 슬러지 생성 과정 및 영향 등을 파악하는 데 짧은 시간 안에 다양하게 실험할 수 있는 이점이 있다.The sludge simulator of the engine oil according to the present invention constructed and acting as described above generates sludge by generating and mixing a constant oil temperature with the same mixed gas as the blow-by gas. There is an advantage that you can experiment variously in a short time.
