Abstract
본 발명은, 수소처리된 중질 파라핀 정제유(Hydraulic Fluid)를 주재로 포함하는, 연료첨가제 조성물에 관한 것으로, 종래에 연료첨가제로 사용되던 PEA(Polyetheramine), PBA(Poly butyl acrylate), 폴리 이소뷰테닐 숙신산 아마이드 (Poly Isobutenyl Succinic Acid Imide), 알킬 페놀 아민(Alkyl Phenols Amine) 등과 달리, 엔진 연소실에 쌓이는 탄소 퇴적물을 후발적으로 제거하는 형태가 아닌, 엔진 연소실 내부에서 연료의 완전연소를 유도하여 탄소 퇴적물의 발생 자체를 방지할 수 있으며, 연소실 안 흡기밸브, 배기밸브, 인젝터 주변에 형성되어 있는 탄소 퇴적물을 효과적으로 제거하는 한편, 내연기관의 연료, 흡배기, 윤활 시스템을 개선하고, 내연기관, 특히 LPG 내연기관의 배출가스 내에서 일산화탄소(CO), 질소산화물(NOx), 황산화물(SOx) 등이 현저히 감소하게 되므로, 친환경적이고 대기오염을 저감할 수 있다.The present invention relates to a fuel additive composition mainly comprising hydrotreated heavy paraffinic refined oil (Hydraulic Fluid).

Description
본 발명은 내연기관용 연료첨가제 조성물, 상세하게는 LPG 내연기관용 연료첨가제 조성물에 관한 것이다.The present invention relates to a fuel additive composition for an internal combustion engine, and more particularly, to a fuel additive composition for an LPG internal combustion engine.
연료첨가제는 연료의 불완전 연소로 인한 엔진 내 잔류물을 세척하거나, 탄소 퇴적물(CCD: Combustion Chamber Deposits)을 감소시켜 연소 과정에서 연소실을 낮은 온도로 유지하며, 잔류물 내지 탄소 퇴적물을 재 연소 과정을 통해 사라지게 하기 위해 사용된다. 구체적으로 엔진 내 잔류물이나 탄소 퇴적물이 사라지게 되면, 연소실의 체적이 증가하게 되어 더 많은 산소가 유입되게 되고, 연소전파속도(화염전파속도)를 더욱 빠르게 진행시킬 수 있게 된다. 이에, 연소실 온도를 낮은 온도로 유지할 수 있게 되고, 출력 상승과 연료 효율 향상을 기대할 수 있다. Fuel additives clean the residues in the engine due to incomplete combustion of fuel or reduce carbon deposits (CCD) to keep the combustion chamber at a low temperature during the combustion process, and to reduce the recombustion process of residues or carbon deposits. It is used to disappear through Specifically, when residues or carbon deposits in the engine disappear, the volume of the combustion chamber increases, allowing more oxygen to flow in, and the combustion propagation speed (flame propagation speed) can be accelerated. Accordingly, it is possible to maintain the combustion chamber temperature at a low temperature, and an increase in output and improvement in fuel efficiency can be expected.
일반적으로 사용되는 연료첨가제들은 세정에 초점을 맞추고 있고, 엔진 내 연소실의 잔류물을 세척하여 제거하기 위하여 세정 성분들을 포함하는데, 폴리에테르아민(Polyetheramine, PEA) 등과 같은 계면활성제 세정 성분들은 연료보다 폭발 온도(인화점)가 높아 연료와 함께 연소되기 어렵고, 이로 인해 완전 연소되지 않은 해당 성분들이 피스톤링을 통과하여 엔진오일 쪽으로 스며들게 되어, 엔진오일의 점도를 희석시키며, 이로 인해 엔진오일 윤활성능이 떨어지게 되고, 엔진에 문제를 발생시킬 수 있는 요인으로 작용한다. Commonly used fuel additives focus on cleaning, and include cleaning components to clean and remove residues from the combustion chamber in the engine. Surfactant cleaning components such as polyetheramine (PEA) are more explosive than fuel. The high temperature (flash point) makes it difficult to combust together with the fuel. As a result, the non-combusted components pass through the piston ring and seep into the engine oil, diluting the viscosity of the engine oil, which leads to a decrease in engine oil lubrication performance. , acting as a factor that can cause engine problems.
이에, 상기와 같은 문제점을 효과적으로 해결하면서, 연소실 내 공급되는 연료의 완전연소를 유도할 수 있는 연료첨가제를 개발하고자 하는 노력이 활발히 이루어지고 있다. 관련하여, 대한민국 등록특허 제10-0544568호에서는, 아민계열의 안정제와 과산화수소, 수산화나트륨, 및 붕사를 특정 중량 비로 포함하는 연료첨가제를 개시하고 있으며, 대한민국 등록특허 제10-0584224호에서는 탄화수소계 용매와 첨가제를 포함하는 내연기관용 연료첨가제를 개시하고 있다. Accordingly, while effectively solving the above problems, efforts are actively being made to develop a fuel additive capable of inducing complete combustion of the fuel supplied into the combustion chamber. In relation to this, Korean Patent No. 10-0544568 discloses a fuel additive comprising an amine-based stabilizer, hydrogen peroxide, sodium hydroxide, and borax in a specific weight ratio, and Korean Patent No. 10-0584224 discloses a hydrocarbon-based solvent. and a fuel additive for an internal combustion engine comprising an additive.

이하, 첨부된 도면을 참조하여 본 발명의 실시예들을 상세하게 설명하면 다음과 같다. 다만, 본 기재를 설명함에 있어서, 이미 공지된 기능 혹은 구성에 대한 설명은, 본 기재의 요지를 명료하게 하기 위하여 생략하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the present description, descriptions of already known functions or configurations will be omitted in order to clarify the gist of the present description.
한편, 본 발명의 명세서 및 도면 전반에서 사용되는 용어인 "수소처리된 중질 파라핀 정제유(Hydraulic Fluid)"는 촉매 존재 하에서 석유 분획물을 수소로 처리하여 얻은 탄화수소의 복잡한 조합으로서, 주로 C20 내지 C50 범위의 탄소수를 가지는 탄화수소로 구성되며, 상대적으로 많은 비율의 포화 탄화수소를 포함하는 것을 의미하는 것일 수 있다. On the other hand, the term "hydrotreated heavy paraffinic refined oil (Hydraulic Fluid)" used throughout the specification and drawings of the present invention is a complex combination of hydrocarbons obtained by treating petroleum fractions with hydrogen in the presence of a catalyst, mainly C 20 to C 50 It is composed of hydrocarbons having a range of carbon atoms, and may mean to include a relatively large proportion of saturated hydrocarbons.
종래 널리 사용되던 연료첨가제들은 엔진 내 연소실의 잔류물을 세척하여 제거하기 위한 세정 성분들을 포함하는데, 폴리에테르아민(Polyetheramine, PEA) 등과 같은 계면활성제 계열의 세정 성분들은 연료보다 폭발 온도(인화점)가 높아 연료와 함께 연소되기 어렵고, 이로 인해 완전 연소되지 않은 해당 성분들이 피스톤링을 통과하여 엔진오일 쪽으로 스며들게 되면, 엔진오일의 점도가 희석되게 되고, 이로 인해 엔진오일 윤활성능이 떨어지게 되며, 이는 엔진에 심각한 문제를 발생시킬 수 있다. 또한, 이러한 연료첨가제들은 엔진 연소실 내 연료의 불완전 연소라는 근본적인 문제를 해결하는 것이 아니라, 연료의 불완전 연소로 인해 이미 발생한 탄소 퇴적물을 후발적으로 제거하는 것에 초점을 맞추고 있을 뿐이며, 이 경우 연비 향상, 출력과 토크 향상, DPF 막힘 방지, 및 요소수 사용량 절감 등의 추가적인 효과를 기대하기 곤란한 문제가 있었다. Conventionally widely used fuel additives include cleaning components for cleaning and removing residues from the combustion chamber in the engine. It is difficult to be combusted with fuel because of this, and if the components that have not been completely burned pass through the piston ring and seep into the engine oil, the viscosity of the engine oil is diluted, which leads to a decrease in engine oil lubrication performance, which in turn affects the engine. It can cause serious problems. In addition, these fuel additives do not solve the fundamental problem of incomplete combustion of fuel in the engine combustion chamber, but only focus on the subsequent removal of carbon deposits that have already occurred due to incomplete combustion of fuel. There was a problem that it was difficult to expect additional effects such as over-torque improvement, DPF clogging prevention, and reduction of urea water consumption.

The present inventors mainly use hydrotreated heavy paraffin refined oil (Hydraulic Fluid) when preparing the fuel additive composition, but when various auxiliary components are mixed in a specific weight part ratio, carbon deposits accumulated in the engine combustion chamber are not subsequently removed, By inducing complete combustion of fuel inside the engine combustion chamber, it is possible to prevent the generation of carbon deposits, effectively removing carbon deposits formed around intake valves, exhaust valves, and injectors in the combustion chamber, while fuel, intake and exhaust of internal combustion engines , the lubrication system can be improved, and carbon monoxide (CO), nitrogen oxide (NO x ), sulfur oxide (SO x ), etc. can be significantly reduced in the exhaust gas of an internal combustion engine, so it is eco-friendly and can reduce air pollution It was confirmed through experimentation that there is, and the present invention was completed.

In the case of hydrotreated heavy paraffinic refined oil, as described above, it is a complex combination of hydrocarbons obtained by treating petroleum fractions with hydrogen in the presence of a catalyst, mainly composed of hydrocarbons having a carbon number in the range of C 20 to C 50 , and relatively many It may include saturated hydrocarbons in a ratio, and specifically, hydrotreated heavy paraffinic refined oil (Hydraulic Fluid) may be included in 95 to 99.5 wt% based on the total weight of the composition.
일반적으로 LPG(Liquefied Petroleum Gas)의 주성분을 이루는 것은 프로판(C3H8)과 부탄(C4H10)이며, 각각 아래 화학식 1 내지 2와 같은 구조를 가진다. In general, the main components of LPG (Liquefied Petroleum Gas) are propane (C 3 H 8 ) and butane (C 4 H 10 ), and have structures as shown in Chemical Formulas 1 and 2 below, respectively.
[화학식 1: 프로판(propane)][Formula 1: propane]
[화학식 2: 부탄(butane)][Formula 2: butane]
