Description

혼합연료 조성물{Mixed Fuel Composition}Mixed Fuel Composition

본 발명은 저공해 혼합연료 조성물에 관한 것으로, 특히 종래 가솔린이 가지고 있는 성능을 그대로 유지하면서 유해성 가스를 배출시킬 수 없는 혼합연료 조성물에 관한 것이다.The present invention relates to a low pollution mixed fuel composition, and more particularly, to a mixed fuel composition in which harmful gas cannot be discharged while maintaining the performance of conventional gasoline.

최근들어, 환경오명의 주범이 되고 있는 유해성 배출가스를 줄이려는 연구가 활발히 진행되고 있다. 특히, 자동차를 구동시키기 위하여 사용되는 가솔린은 연소시에 이산화황, 질소산화물 등의 유해성 가스를 배출하고 있어 환경을 파괴하고 있다. 이러한 유해성 가스를 줄여야할 필요성이 절실하다.In recent years, researches are being actively conducted to reduce harmful emissions, which are the main culprit of environmental stigma. In particular, gasoline used to drive automobiles emits harmful gases such as sulfur dioxide and nitrogen oxide during combustion, thereby destroying the environment. There is an urgent need to reduce these harmful gases.

따라서, 본 발명의 목적은 기존의 가솔린이 가지고 있는 성능을 그대로 유지하면서 유해성 가스를 배출시킬 수 없는 혼합연료 조성물을 제공하는 것이다.Accordingly, it is an object of the present invention to provide a mixed fuel composition that can not release harmful gases while maintaining the performance of the existing gasoline as it is.

상기 가솔린은 무연 휘발유인 것을 특징으로 한다.The gasoline is characterized in that it is unleaded gasoline.

상기 목적 외에 본 발명의 다른 목적 및 이점들은 첨부도면을 참조한 본 발명의 바람직한 실시 예에 대한 설명을 통하여 명백하게 드러나게 될 것이다.Other objects and advantages of the present invention in addition to the above object will be apparent from the description of the preferred embodiment of the present invention with reference to the accompanying drawings.

이하, 도 1 내지 도 5를 참조하여 본 발명의 바람직한 실시 예를 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 1 to 5.

본 발명의 실시 예에 따른 혼합연료 조성물은 40.0 ~ 44.0 중량%의 혼합알콜과, 11.5 ~ 14.0 중량%의 이소부탄올과, 1.0 ~ 3.0 중량%의 메틸 테트부틸 에테르(Methyl tert-Butyl Ether)와, 32.0 ~ 35.0 중량%의 가솔린과, 16.0 ~ 4.0 중량%의 탄화수소류로 이루어진다.Mixed fuel composition according to an embodiment of the present invention is a mixed alcohol of 40.0 ~ 44.0 wt%, 11.5 ~ 14.0 wt% isobutanol, 1.0 ~ 3.0 wt% of methyl tert-Butyl Ether, It is composed of 32.0 to 35.0% by weight of gasoline and 16.0 to 4.0% by weight of hydrocarbons.

여기서, 본 발명의 혼합연료는 에탄올 및 이소부탄올을 주성분으로 하는 조성물로서 내연기관의 옥탄가를 높여주며, 연소시 이산화황 및 질소산화물 등을 배출시키지 않는다는 장점을 가진다.Here, the mixed fuel of the present invention has the advantage of increasing the octane number of the internal combustion engine as a composition composed mainly of ethanol and isobutanol, and does not emit sulfur dioxide and nitrogen oxides during combustion.

혼합알콜은 에탄올 62 중량%과 이소프로판을 38 중량%의 혼합물이다.Mixed alcohol is a mixture of 62% by weight of ethanol and 38% by weight of isopropane.

여기서, 에탄올의 구조식은 C2H5OH(분자량 46g/mol)이며 무색을 가지는 휘발성 액체로서 융점은 -114.1℃, 비중은 0.789, 굴절률은 1.361이다. 이러한 에탄올은 물, 에테르, 탄화수소류 등과 같은 혼합성이 뛰어나며, 각종 합성품의 용제나 기초원료로 그 이용성이 높다. 특히, 2 사이클 엔진의 연소 시스템에는 지금까지 없었던 세정 효과 뿐만 아니라 동시에 그 상승효과로서 내연기의 피스톤의 윤활효과를 높여준다.Herein, the structural formula of ethanol is C 2 H 5 OH (molecular weight 46 g / mol), a colorless volatile liquid having a melting point of −114.1 ° C., a specific gravity of 0.789, and a refractive index of 1.361. The ethanol is excellent in mixing properties such as water, ether, hydrocarbons, etc., and has high utility as a solvent or basic raw material for various synthetic products. In particular, the lubrication effect of the piston of the internal combustion engine is enhanced as well as a synergistic effect as well as the cleaning effect which has not been present in the combustion system of the two cycle engine.

에탄올과 이소부탄올은 연료의 점도를 내려 부드러운 유동성을 촉진하여 내연기에 고출력을 발생시키는 역할을 한다.Ethanol and isobutanol lower the viscosity of the fuel and promote smooth fluidity, which plays a role of generating high output in the internal combustion.

가솔린을 첨가함으로써 기존의 가솔린연료에 의한 내연기의 개조와 같은 구조변경없이 점화시의 폭발력 증가를 촉진하여 엔진의 출력을 향상시킬 수 있다.By adding gasoline, the output of the engine can be improved by facilitating an increase in the explosive power during ignition without a structural change such as the modification of the internal combustion engine by the existing gasoline fuel.

표 1에 나타난 바와 같이 본 발명의 혼합연료 조성물의 일 성분인 혼합알콜의 조성을 기존 제품과 비교 분석한 결과 불완전 연소에 의한 공해를 유발할 수 있는 성분(톨루엔, 나프타 등)이 본 발명의 조성물에서는 검출되지 않는다.As shown in Table 1, the composition of mixed alcohol, which is one component of the mixed fuel composition of the present invention, was analyzed in comparison with existing products, and the components (toluene, naphtha, etc.) that could cause pollution due to incomplete combustion were detected in the composition of the present invention. It doesn't work.

(실시 예 2)배출가스 측정 시험Example 2 Exhaust Gas Measurement Test

본 발명의 제2 실시 예에 따라 혼합연료 조성물이 연소할 때 배출되는 가스를 측정하기로 한다. 이때, 사용되는 자동차 즉, 원동기의 성능은 다음에서 주어진다.According to the second embodiment of the present invention, the gas discharged when the mixed fuel composition is burned will be measured. At this time, the performance of the motor vehicle, that is, the prime mover used, is given by the following.

본 발명의 혼합연료 조성물과 일본 GAIAX 社 제품을 동일 시험 차량으로 시험한 결과 승용자동차의 배출가스 허용 기준을 모두 만족하였고, 또한 본 조성물은 비교 제품인 GAIAX 社 제품보다 유해 성분의 배출이 거의 없었다.As a result of testing the mixed fuel composition of the present invention and the product of Japan GAIAX Co., Ltd. in the same test vehicle, all of the emission standards of the passenger car were satisfied, and the composition showed less emission of harmful components than the product of GAIAX Co., Ltd. which is a comparative product.

이것은 본 조성물의 주성분은 혼합 알콜을 비롯하여 거의가 알콜류로서 불완전 연소에 의한 유해 가스의 배출이 없기 때문이다.This is because the main components of the composition are mixed alcohols and almost alcohols, and there is no emission of harmful gases due to incomplete combustion.

이상의 실시 예들에서 검토된 바와 같이 본 조성물의 혼합연료는 가솔린 및 기존 가솔린 대체 연료와 동일한 성능을 유지하면서 유해가스의 배출이 거의 없는 친환경적인 혼합연료 조성물이다. 이는 다음의 표 3은 배기가스의 비교 측정 결과에서 나타남을 알 수 있다.As discussed in the above embodiments, the mixed fuel of the present composition is an eco-friendly mixed fuel composition that maintains the same performance as gasoline and the existing gasoline alternative fuel and emits no harmful gases. This can be seen that the following Table 3 is shown in the comparative measurement results of the exhaust gas.

상술한 바와 같이, 본 발명에 따른 혼합연료 조성물은 현행의 환경 기준에 부합될 뿐만 아니라 가솔린 및 기존 시판되고 있는 혼합알콜연료(예; 일본 GAIAX)에 비하여 배출가스의 발생량이 현저히 감소되며, 점차 강화되고 있는 각국의 환경 기준에도 적합한 친환경적인 대체 연료로 사용될 수 있다.As described above, the mixed fuel composition according to the present invention not only meets the current environmental standards, but also significantly reduces the amount of emitted gas compared to gasoline and commercially available mixed alcohol fuel (for example, Japan GAIAX), and gradually strengthens it. It can be used as an eco-friendly alternative fuel that meets the environmental standards of each country.
