Abstract
본 발명은 내연기관의 실린더와 피스톤의 구성물질중 철과 치환관계에 있는 준금속광물인 규소를 이용하여 기존에 설치된 실린더와 피스톤의 알루미늄(Al), 철(Fe)성분과의 치환반응을 통해 표면을 개질하는 엔진오일 및 엔진오일 첨가제에 관한 것이다.
본 발명의 엔진오일 첨가제 및 엔진오일은 내연기관의 실린더와 피스톤의 표면을 개질하여 연비를 신차수준까지 향상시키고 꾸준히 유지할 수 있는 기술의 토대를 마련한다.
따라서, 오래된 차량의 나빠진 연비라도 연비가 개선될 수 있고, 연비가 나빠지지 않게 지속적으로 운행이 가능해진다. The present invention uses silicon, a metalloid mineral in a substitutional relationship with iron among the components of the cylinder and piston of an internal combustion engine, through a substitution reaction with the aluminum (Al) and iron (Fe) components of the existing cylinder and piston.

The engine oil additive and engine oil of the present invention reform the surface of the cylinder and piston of an internal combustion engine to improve fuel efficiency to the level of a new car and lay the foundation for technology that can be steadily maintained.

Description
본 발명은 내연기관의 실린더 및 피스톤의 표면을 개질하는 엔진오일 첨가제 및 엔진오일에 관한 것이다The present invention relates to engine oil additives and engine oils that modify the surfaces of cylinders and pistons of internal combustion engines.
자동차를 포함한 차량운반구의 대부분은 실린더와 피스톤으로 구성된 내연기관으로 작동한다. Most vehicles, including automobiles, operate with internal combustion engines consisting of cylinders and pistons.
따라서 차량의 연식이 오래되거나, 운행거리가 늘어날수록, 실린더와 피스톤은 마모되거나, 산화되는 과정을 거치면서 신차의 연비를 유지하지 못하게 된다. Therefore, as the vehicle gets older or the mileage increases, the cylinders and pistons wear out or go through an oxidation process, making it impossible to maintain the fuel efficiency of a new vehicle.
이러한 실린더와 피스톤으로 구성된 내연기관의 문제는 한번 차량운반구가 만들어지면, 실린더와 피스톤이 마모, 산화 등으로 인하여, 내구성이 지속적으로 나빠지게 된다. 따라서, 쉽게 내연기관을 교체할 수 없기 때문에 내연기관용 엔진오일 등으로 엔진수명 연장 및 성능 향상을 기대하거나 요구하게 되었다.The problem with internal combustion engines consisting of cylinders and pistons is that once a vehicle carrier is made, the durability of the cylinders and pistons continues to deteriorate due to wear and oxidation. Therefore, since the internal combustion engine cannot be easily replaced, there has been an expectation or demand for engine oil for internal combustion engines to extend engine life and improve performance.
이러한 실린더와 피스톤의 문제를 개선하기 위하여 엔진오일에 점도개선을 위한 고분자나 마찰계수를 조절하기 위하여 산화물 형태의 실리카, 알루미나, 산화망간등을 사용하거나, 금속분말인 구리, 니켈, 크롬, 망간등을 사용하거나, 고체윤활제인 그라파이트, 이산화몰리브덴을 사용하여 왔다. To improve these cylinder and piston problems, polymers to improve viscosity in engine oil, oxides such as silica, alumina, and manganese oxide to adjust the friction coefficient, or metal powders such as copper, nickel, chromium, and manganese are used. Alternatively, solid lubricants such as graphite and molybdenum dioxide have been used.
이러한 엔진오일의 과거 기대효과는 연비개선 및 환경부화 저감등의 새로운 개념으로 바뀌고 있다. These past expected effects of engine oil are being replaced by new concepts such as improved fuel efficiency and reduced environmental degradation.
한편, 대한민국 특허 출원번호 10-2016-0099885 호 엔진오일 첨가제 및 엔진 윤활방법 특허의 청구항을 보면, 구 형상을 갖는 이산화규소 재질의 20~30나노입자를 설명하고 있다. Meanwhile, looking at the claims of the engine oil additive and engine lubrication method patent in Korea Patent Application No. 10-2016-0099885, it describes 20 to 30 nanoparticles made of silicon dioxide having a spherical shape.
다른 한편으로는 대한민국 특허 출원번호 10-2020-0066098 호 다공성 실리카 나노 입자를 포함하는 윤활유 및 이의 제조방법의 청구항을 보면, 10 ~ 100 nm 크기인 원형의 다공성 실리카(SiO2)를 함유하는 윤활유를 설명하고 있다. On the other hand, looking at the claims of Korean Patent Application No. 10-2020-0066098, a lubricant containing porous silica nanoparticles and a manufacturing method thereof, it describes a lubricant containing circular porous silica (SiO2) with a size of 10 to 100 nm. I'm doing it.
이 두개의 특허문헌을 살펴보면 구형의 나노입자가 나노 베어링의 역할을 수행할 것을 기대하거나, 기능할 수 있다고 주장한다. Looking at these two patent documents, it is claimed that spherical nanoparticles are expected to perform the role of nano bearings, or can function.
그러나, 이 두개의 특허 문헌의 내용은 실린더와 피스톤 내부의 물리적 환경과 현상, 이산화 규소 및 규소의 물리적 특성을 전혀 이해하지 못하고 작성된 특허라 할 수 있다. 즉, 이산화규소를 사용하여 무엇인가 개선된 효과를 보기는 하였으나 물리적 현상을 이해하지 못하여 잘 못 만들어진 특허라 할 수 있다. However, the contents of these two patent documents can be said to be patents written without any understanding of the physical environment and phenomena inside the cylinder and piston, and the physical properties of silicon dioxide and silicon. In other words, although some improved effects were seen using silicon dioxide, it can be said to be a poorly made patent due to a lack of understanding of physical phenomena.
그에 따라, 오래된 차량의 소음 개선 및 연비개선 등의 효과를 극대화하기 위하여 물리적 현상을 다시 규명하여야 할 필요성이 있으며, 오래된 차량도 신차 수준의 연비를 가질 수 있는 새로운 해석 및 해석에 따른 사용방법이 제시될 필요성이 있다.Accordingly, there is a need to re-examine physical phenomena in order to maximize the effects of improving noise and fuel efficiency of old vehicles, and new interpretations and methods of use based on interpretation are proposed so that even old vehicles can have fuel efficiency at the same level as new cars. There is a need to become
따라서, 이산화규소와 규소의 물리적 특성을 명확히 규명하고 실린더와 피스톤을 가진 내연기관에서 일어날 수 있는 환경속에서 발생하는 물리적현상을 명확히 해석하여 적합한 엔진오일 첨가제 및 이를 함유한 엔진오일을 개발할 필요가 있다. Therefore, it is necessary to clearly identify the physical properties of silicon dioxide and silicon, clearly interpret the physical phenomena that occur in the environment that can occur in an internal combustion engine with a cylinder and piston, and develop suitable engine oil additives and engine oil containing them. .
이에 본 발명에서는 Accordingly, in the present invention
준금속 원소인 이산화규소의 물리적 특성을 파악하여 내연기관의 실린더 속에 환경에서 일어날 수 있는 물리적 현상을 해석하여, 새로운 실험을 통해 엔진오일 및 엔진오일 첨가제를 제공하는 것을 목적으로 한다.The purpose is to understand the physical properties of silicon dioxide, a metalloid element, analyze physical phenomena that may occur in the environment in the cylinder of an internal combustion engine, and provide engine oil and engine oil additives through new experiments.
본 발명의 다른 목적은 내연기관의 실린더와 피스톤을 오래도록 사용하여도 신차 수준의 연비를 꾸준히 유지할 수 있는 엔진오일 및 엔진오일 첨가제를 제공하는 것이다. Another object of the present invention is to provide engine oil and engine oil additives that can consistently maintain fuel efficiency at the level of a new car even when the cylinder and piston of an internal combustion engine are used for a long time.
본 발명의 특별한 효과는 피스톤과 실린더로 구성된 내연기관의 구성 성분에 해당하는 알루미늄(Al) 성분, 철(Fe)성분과 치환반응에 의한 표면 개질 효과로 오래된 엔진의 연비를 신차 수준으로 회복시켜주는 것이다. The special effect of the present invention is to restore the fuel efficiency of an old engine to the level of a new car through a surface modification effect through a substitution reaction with aluminum (Al) and iron (Fe) components, which are components of an internal combustion engine consisting of a piston and a cylinder. will be.
본 발명의 엔진오일 및 엔진오일 첨가제는 치환반응 관계에 있는 규소를 첨가하여 지속적으로 사용하는 내연기관의 피스톤과 실린더를 보호하여 연비가 악화되는 것을 방지하는 역할을 기대할 수 있다. The engine oil and engine oil additive of the present invention can be expected to play a role in preventing deterioration of fuel efficiency by protecting the pistons and cylinders of internal combustion engines that are continuously used by adding silicon that is involved in a substitution reaction.

이하에서 본 발명을 더욱 상세하게 설명하면 다음과 같다. The present invention will be described in more detail below.
내연기관의 실린더 내부 연소가스의 온도는 2,000 ~ 2,500°C 에 이른다. The temperature of combustion gases inside the cylinder of an internal combustion engine ranges from 2,000 to 2,500°C.
이 온도는 이산화규소(SiO2)의 녹는점인 1,710°C를 넘어서는 온도이다. 규소 자체의 녹는점도 1,414°C로 실린더 내부 연소가스의 온도 보다 낮다. This temperature exceeds 1,710°C, the melting point of silicon dioxide (SiO2). The melting point of silicon itself is 1,414°C, which is lower than the temperature of the combustion gas inside the cylinder.
따라서, 구형 이산화규소 나노입자를 실린더 내부에 넣는다 하여도 이산화규소의 녹는점보다 더 높은 온도의 환경이 구현되는 실린더 내부에서 구형의 형태를 유지한다는 것은 물리적 해석에 의하면 불가능하다. Therefore, even if spherical silicon dioxide nanoparticles are placed inside a cylinder, according to physical analysis, it is impossible to maintain the spherical shape inside the cylinder, which is in an environment with a temperature higher than the melting point of silicon dioxide.
또한 실린더 내부 온도가 비록 낮다 하더라도, 실린더 내부에서 작용하는 힘에 의해서 구형입자는 산산히 부서질 것이다. Also, even if the temperature inside the cylinder is low, the spherical particles will be shattered by the force acting inside the cylinder.
그에 따라, 구형의 나노입자가 나노 베어링 역할을 한다는 것은 더더욱 불가능한 것이다. Accordingly, it is even more impossible for spherical nanoparticles to function as nano bearings.
그러므로 구형의 나노입자를 반드시 써야 할 이유가 없어진다. Therefore, there is no reason to use spherical nanoparticles.
또 규소화합물중에서 반드시 이산화규소를 사용해야 할 이유도 없어진다. 그것은 규소(Silicon)가 실린더 내부에서 일으키는 물리적 현상을 이해하지 못하여 이산화규소를 사용한 것이지 실제로는 더 낮은 온도의 녹는점을 가지는 규소화합물을 사용하는 것이 바람직하다. Also, there is no reason to necessarily use silicon dioxide among silicon compounds. Silicon dioxide was used because the physical phenomenon that silicon causes inside the cylinder was not understood. In reality, it is preferable to use a silicon compound with a lower melting point.
규소화합물 사용의 목적도 엔진오일의 윤활성 증가가 목적이 아니라, 실린더와 피스톤을 구성하는 소재중 알루미늄(Al), 철(Fe)과의 치환반응이 목적이기 때문에 사용량도 소량이 아니라 비교적 많아지게 된다. The purpose of using silicon compounds is not to increase the lubricity of engine oil, but to cause a substitution reaction with aluminum (Al) and iron (Fe) among the materials that make up the cylinder and piston, so the amount used is not a small amount, but a relatively large amount. .
내연기관의 실린더는 실린더 내에서 고온, 고압의 연소가스와 접촉하므로 열전달이 우수하며 가볍고 견고해야 하기 때문에 알루미늄 합금인 Y합금이나 저 팽창률을 가진 로엑스합금(Lo-Ex alloy)을 사용한다. The cylinder of an internal combustion engine is in contact with high-temperature and high-pressure combustion gases within the cylinder, so it must have excellent heat transfer and be light and strong. Therefore, Y alloy, an aluminum alloy, or Lo-Ex alloy with a low expansion rate is used.
대표적인 규소 화합물의 녹는점을 비교해보면, 규소의 녹는점 1,414°C , 일산화규소의 녹는점 1,710°C, 이산화규소의 녹는점 1,710°C, 규소의 대표적인 화합물인 유리의 녹는점 750°C, 메타규산나트륨(무수물) 녹는점 1088°C , 메타규산나트륨 5수화물 녹는점 72°C , 메타규산나트륨 9수화물 녹는점 48°C 이다. Comparing the melting points of representative silicon compounds, the melting point of silicon is 1,414°C, the melting point of silicon monoxide is 1,710°C, the melting point of silicon dioxide is 1,710°C, the melting point of glass, a representative silicon compound, is 750°C, meta The melting point of sodium silicate (anhydrous) is 1088°C, the melting point of sodium metasilicate pentahydrate is 72°C, and the melting point of sodium metasilicate nonahydrate is 48°C.
물분자가 포함된 메타규산나트륨 5수화물 또는 메타규산나트륨 9수화물은 낮은 온도에서 이온이 될 수 있다. Sodium metasilicate pentahydrate or sodium metasilicate nonahydrate containing water molecules can become ions at low temperatures.
이외에 규산칼슘(CaSiO3) 녹는점 1,250°C~1,500°C이 있다. In addition, calcium silicate (CaSiO3) has a melting point of 1,250°C to 1,500°C.
본 발명에 의한 엔진오일 첨가제와 엔진오일은 실린더와 피스톤의 구성성분d에 해당하는 알루미늄 성분, 철 성분과 치환관계에 있는 규소를 실린더 내부에 투입시켜 녹는점 이상의 높은 온도에서 이온이 되어 치환반응에 의하여 실린더 내부와 피스톤 외부에 포함되어 있는 알루미늄 성분, 철성분과 치환 반응하여 높은 윤활성과 내마모성을 가지도록 개질하는 특성이 있다. The engine oil additive and engine oil according to the present invention are made by adding silicon, which is in a substitutional relationship with the aluminum component and iron component, corresponding to the component d of the cylinder and piston, into the cylinder and becoming ions at a high temperature above the melting point, thereby causing a substitution reaction. It has the property of being reformed to have high lubricity and wear resistance through a substitution reaction with the aluminum and iron components contained inside the cylinder and outside the piston.
따라서, 본 발명에 의하여 개질된 내연기관의 실린더 내부와 피스톤 외부는 신차 수준의 윤활성과 내마모성을 가지게 됨으로 인하여, 연비저하, 소음, 진동, 매연등의 문제를 신차 수준으로 회복시킬 수 있게 되는 것이다. Accordingly, the inside of the cylinder and the outside of the piston of the internal combustion engine modified by the present invention have lubricity and wear resistance at the level of a new car, so that problems such as reduced fuel efficiency, noise, vibration, and exhaust fumes can be restored to the level of a new car.
본 발명에서는 이산화규소를 사용할 수 있지만, 이산화규소 보다는 더 낮은 온도에서 결합에너지를 끊어 쉽게 이온이 될 수 있는 규소 화합물을 사용하는 것이 바람직하다. In the present invention, silicon dioxide can be used, but it is preferable to use a silicon compound that can easily become an ion by breaking the bond energy at a lower temperature than silicon dioxide.
이런 낮은 온도의 녹는점을 가진 규소 화합물의 사용은 내연기관의 실린더 온도가 상승할때까지 기다리지 않아도 쉽게 치환반응이 일어나는 것을 기대할 수 있기 때문이다. The use of a silicon compound with such a low melting point is because the substitution reaction can be expected to easily occur without waiting for the cylinder temperature of the internal combustion engine to rise.
그 중 메타규산나트륨 5수화물 ( Na2SiO3-5H2O ) , 메타규산소다 9수화물 ( Na2SiO3-9H2O )이 가장 낮은 온도에서 쉽게 이온이되고, 알칼리 pH를 가지고 있어 산화방지제 역할을 기대할 수 있어 적합하다. Among them, sodium metasilicate pentahydrate (Na2SiO3-5H2O) and sodium metasilicate nonahydrate (Na2SiO3-9H2O) are suitable as they easily become ions at the lowest temperature and have an alkaline pH, so they can be expected to act as antioxidants.
또한 메타규산나트륨에 포함되어 있는 나트륨은 금속 양이온으로서 강한 양극과 음극이 검댕(Soot)이나 오염 물질들이 서로 뭉치거나 표면에 붙기 전에 물질 전체를 감싸서 오일과 분리되도록 만드는 청정제 역할을 기대할 수 있다. In addition, the sodium contained in sodium metasilicate is a metal cation, and the strong anode and cathode can be expected to act as a cleaning agent that surrounds the entire material and separates it from oil before soot or contaminants clump together or stick to the surface.
규산칼슘(CaSiO3) 또한 포함되어 있는 칼슘이 청정제의 역할을 기대할 수 있고, 아주 효율적인 규소이온의 공급원이 된다. 그러나 메타규산나트륨보다 용해도가 떨어지기고, 녹는점이 높아서 사용성이 쉽지 않다. Calcium, which also contains calcium silicate (CaSiO3), can be expected to act as a cleaning agent and is a very efficient source of silicon ions. However, its solubility is lower than that of sodium metasilicate and its melting point is high, making it difficult to use.
규산칼슘, 메타규산나트륨무수물, 메타규산나트륨5수화물, 메타규산나트륨9수화물, 일산화규소, 이산화규소는 내연기관의 실린더 연소가스의 온도에서 치환반응을 일으키는 유효성분으로 사용될 수 있다. 그러나 낮은 녹는점을 가지고 있는 규산나트륨 5수화물과 규산나트륨 9수화물이 본 발명에 가장 적합하다. Calcium silicate, sodium metasilicate anhydrous, sodium metasilicate pentahydrate, sodium metasilicate nine hydrate, silicon monoxide, and silicon dioxide can be used as active ingredients that cause a substitution reaction at the temperature of the cylinder combustion gas of an internal combustion engine. However, sodium silicate pentahydrate and sodium silicate nonahydrate, which have a low melting point, are most suitable for the present invention.
실시예Example
대한민국 현대 자동차가 제조한 투싼 자동차 신차의 복합연비는 12 ~ 16km/L에 이른다. The combined fuel efficiency of the new Tucson car manufactured by Hyundai Motor Company of Korea ranges from 12 to 16 km/L.
이 자동차를 130,000km 이상 운행한 차량에 시험하였다. This car was tested on a vehicle driven for more than 130,000 km.
도면 1은 본 발명의 첨가제를 첨가하지 않은 상태. ( 총 주행거리 138,412km ) 연비 3.6km/L를 나타낸다. Figure 1 shows the state without adding the additive of the present invention. (Total mileage 138,412km) Fuel efficiency is 3.6km/L.
신차대비 연비가 현저하게 떨어진 것을 보여주고 있다. It shows a significant drop in fuel efficiency compared to new cars.
해당차량의 엔진오일에 메타규산소다 9수화물 10g을 엔진오일 첨가제로 사용하였다. 10g of sodium metasilicate nonahydrate was used as an engine oil additive in the engine oil of the vehicle.
메타규산나트륨 9수화물에 엔진오일을 섞고 흔들어서 투입하였다. Sodium metasilicate nonahydrate was mixed with engine oil, shaken, and then added.
이산화규소도 동시에 사용할 수 있으나 메타규산나트륨 9수화물의 효과를 검증하기 위하여 단독으로 사용하였다. Silicon dioxide can be used simultaneously, but it was used alone to verify the effect of sodium metasilicate nonahydrate.
입자의 모양은 특별할 것 없으나 크기는 엔진오일과 잘 섞이는 수준의 100nm 이하가 적당하다. 경우에 따라서는 분산성을 높이기 위하여 볼밀을 이용하여 크기를 줄일 필요가 있다. The shape of the particles is not special, but the appropriate size is 100 nm or less, which is enough to mix well with engine oil. In some cases, it is necessary to reduce the size using a ball mill to increase dispersibility.
도면 2는 본 발명의 첨가제를 투입하고 32km를 주행한 평균연비이다. ( 총 주행거리 138,444km ) 연비는 9.5km/L를 나타냈다. Figure 2 shows the average fuel efficiency for driving 32 km after adding the additive of the present invention. (Total mileage 138,444km) Fuel efficiency was 9.5km/L.
아직 신차 수준의 연비에는 이르지 못했다. It has not yet reached the level of fuel efficiency of a new car.
도면 3은 추가로 10km를 주행한 후 연비의 사진이다. (총 주행거리는 138,454km ) 평균연비는 10.6km/L 이다. Figure 3 is a photo of fuel efficiency after driving an additional 10 km. (Total driving distance is 138,454km) The average fuel efficiency is 10.6km/L.
도면 4는 추가로 379km 를 주행한 후 연비의 사진이다. ( 총 주행거리는 138,833km ) 평균연비는 12.9km/L 이다. Figure 4 is a photo of fuel efficiency after driving an additional 379 km. (Total driving distance is 138,833km) Average fuel efficiency is 12.9km/L.
상기 실시예에서 보듯이, 구형의 이산화규소가 필요한 것이 아니고, 내연기관의 실린더와 피스톤을 구성하는 물질중 하나에 해당하는 철과의 치환반응을 통하여 표면이 규소로 개질된 실린더와 피스톤의 윤활성이 극대화 되면서 신차 수준의 연비로 개선할 수 있음을 보여준다. As seen in the above example, spherical silicon dioxide is not necessary, but the lubricity of the cylinder and piston whose surfaces are modified with silicon through a substitution reaction with iron, which is one of the materials that make up the cylinder and piston of an internal combustion engine, is improved. This shows that fuel efficiency can be improved to that of a new car by being maximized.
뿐만 아니라, 매연, 진동, 소음등도 눈에 띄게 개선되는 효과가 있다. In addition, there is a noticeable improvement in smoke, vibration, and noise.
본 발명의 엔진오일 첨가제나 엔진오일을 사용함으로 인하여 꾸준히 신차 수준의 연비와 성능을 유지할 수 있는 길이 열린다. By using the engine oil additive or engine oil of the present invention, a way is opened to continuously maintain fuel efficiency and performance at the level of a new car.
이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에 만 한정되는 것은 아니며, 특허 청구 범위에 기재된 범주내에서 적절하게 변경 가능한 것이다. Although preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately modified within the scope described in the patent claims.
