Description

디젤엔진의 출력 증가장치{Output increasing apparatus of diesel engine}Output increasing apparatus of diesel engine

본 발명은 디젤엔진의 연소실 내부에 일정비의 공기와 가솔린의 옥탄가를 높이는 보조연료를 서로 혼합하여 완전 연소시키므로서 엔진에 손상을 주지 않고 출력을 증가시킬 수 있도록 함을 목적으로 안출한 디젤엔진의 출력 증가장치에 관한 것이다.The present invention is a diesel engine prepared for the purpose of increasing the power without damaging the engine by completely mixing the auxiliary fuel to increase the octane number of gas and gasoline of a certain ratio in the combustion chamber of the diesel engine. It relates to an output increasing device.

일반적으로 디젤엔진의 연소실 내부에는 연료와 공기가 동시에 혼합되어 피스톤의 압축으로 연소되고 폭발되어 출력을 발생시키게 되는 데, 종래 디젤엔진에 사용되는 연료는 연소실의 내부에 분사노즐로서 분사하여 유입시켜도 연료 자체가휘발성이 낮으므로 완전연소가 되지 않아 연료의 소모량은 많은 반면에 엔진의 출력이 높지 않고 경제성이 없으며 엔진의 수명도 짧아지는 폐단이 있었다.In general, fuel and air are mixed at the same time in a combustion chamber of a diesel engine to be burned and exploded by compression of a piston to generate an output. The fuel used in a conventional diesel engine may be injected into the combustion chamber by injecting it as an injection nozzle. Because of its low volatility, it is not completely burned and consumes a lot of fuel, while the output of the engine is not high, it is not economical, and the life of the engine is shortened.

본 발명은 이와같은 점을 감안하여 안출한 것으로 디젤엔진의 연소실로 유입되는 공기흡입라인에 에어와 옥탄가 증가용 보조연료를 혼합 분사시키는 분사노즐을 설치하여 엔진의 연소실로 고압 분사시키므로서 연료를 완전 연소시켜 엔진의 출력을 증가시키고 완전연소로 인한 매연을 감소시킨데 그 특징이 있다.The present invention has been devised in view of the above-mentioned problem, and a fuel nozzle is installed in an air suction line flowing into a combustion chamber of a diesel engine to inject a mixture of air and octane increase auxiliary fuel to inject high pressure into the combustion chamber of the engine, thereby completely fueling the fuel. Combustion increases engine output and reduces soot from complete combustion.

이하 본 발명을 첨부도면에 의거 상술하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

연료유입구(1)와 공기흡입구(2)가 각각 설치된 통상의 디젤엔진(3)에 있어서 공기흡입구(2)와 연결된 공기흡입관(4)에 차량의 에어탱크(5)로 부터 공급되는 에어를 압력조절기(6)와 밸브(7)로서 조절공급하는 에어 공급라인(8)과 아세톤 25%, 크실렌 25%, 경유 50%를 혼합하여서 되는 보조연료(9)를 필터(10)와 밸브(7')로서 조절공급하는 보조연료 공급라인(11)을 각각 연결 설치하여 에어 공급라인(8)과 보조연료 공급라인(11)을 통해 공급되는 에어와 보조연료(9)를 기화용 혼합 분사장치(12)로서 디젤엔진(3)의 연소실에 공급하여서 되는 것이다.In a conventional diesel engine (3) provided with a fuel inlet (1) and an air inlet (2), respectively, the air supplied from the air tank (5) of the vehicle is supplied to the air intake pipe (4) connected to the air inlet (2). The air supply line 8 which regulates and supplies the regulator 6 and the valve 7 and the auxiliary fuel 9 which mixes 25% of acetone, 25% of xylene, and 50% of diesel oil are provided with the filter 10 and the valve 7 '. The auxiliary fuel supply line 11 to be regulated and supplied, respectively, so that the air and the auxiliary fuel 9 supplied through the air supply line 8 and the auxiliary fuel supply line 11 are vaporized. ) Is supplied to the combustion chamber of the diesel engine (3).

도면중 미설명 부호 13은 공기흡입관(4)에 설치된 에어크리너이고, 14는 혼합분사장치(12)에 형성된 에어유입구이며, 15는 보조연료 유입구이다.In the figure, reference numeral 13 denotes an air cleaner installed in the air suction pipe 4, 14 denotes an air inlet formed in the mixed injection device 12, and 15 denotes an auxiliary fuel inlet.

이와같이 된 본 발명은 기존의 연료 공급기구의 변형 개조없이 기 설치된 공기흡입관(4)의 내부에 기화용 혼합 분사장치(12)를 설치하고 이의 에어유입구(14)에는 차량의 에어탱크(5)로 부터 공급되는 에어를 압력조절기(6)와 밸브(7)로서 조절공급하는 에어 공급라인(8)을 연결하고 보조연료 유입구(15)에는 아세톤 25%, 크실렌 25%, 경유 50%를 혼합하여서 되는 보조연료(9)를 필터(10)와 밸브(7')로서 조절공급하는 보조연료 공급라인(11)을 각각 연결 설치하여서 되는 것이므로 엔진에 공급되는 공기속에 차량의 에어탱크(5)로 부터 공급되는 별도의 에어와 휘발성이 매우 높은 보조연료(9)를 기화용 혼합 분사장치(12)에 의해 기화상태로 분사시키게 되면 주연료인 디젤 기화가스와 보조연료 기화가스가 엔진의 연소실에서 서로 혼합되어 엔진 실린더 압축에 의하여 연소되는 데 이때 주연료와 혼합된 보조연료는 전술한 바와 같이 휘발성이 높고 옥탄가가 매우 높은 아세톤 25%, 크실렌 25%, 경유 50%가 혼합된 것이므로 엔진의 연소실에서 연소시 완전연소가 이루어져 배기됨에 따라 전체적인 열량이 매우 높아져 엔진의 출력이 높아지게 되는 것이다.The present invention thus achieved is installed in the air inlet pipe 4 of the pre-installed air intake pipe (4) without modification and modification of the existing fuel supply mechanism and its air inlet 14 to the air tank (5) of the vehicle By connecting the air supply line (8) which regulates and supplies the air supplied from the pressure regulator (6) and the valve (7), and mixes 25% acetone, 25% xylene, and 50% diesel oil in the auxiliary fuel inlet (15). Since the auxiliary fuel supply line 11 which regulates and supplies the auxiliary fuel 9 as the filter 10 and the valve 7 'is respectively connected and installed, it is supplied from the air tank 5 of the vehicle to the air supplied to the engine. When the separate air and the highly volatile secondary fuel 9 are injected into the vaporized state by the vaporization mixing injector 12, the diesel gas and the secondary fuel vaporized gas, which are the main fuels, are mixed with each other in the combustion chamber of the engine. On engine cylinder compression In this case, the auxiliary fuel mixed with the main fuel is acetone 25%, xylene 25%, and diesel oil 50% which are highly volatile and have a very high octane number as described above. As a result, the overall calorific value is very high and the engine output is high.

일반적으로 가솔린 엔진에서 일정량의 연료를 사용하여 그 효율을 높이기 위해서는 첫째 써말가(THERMAL VALUE)가 높아야 되고, 둘째 옥탄가가 증가되어야 하는 데 여기서 옥탄가를 증가시키기 위해서는 크랙킹을 위한 촉매의 첨가와 녹킹을 방지하기 위한 안티 녹킹제를 주입하는 방법이 있는 바 종래 이러한 방법외에 옥탄가를 높이기 위해서 가솔린에 물 또는 알코홀을 소량 혼입시켜 소정의 효과를 거둔 예는 있으나 그 위험성과 부작용 때문에 실용성이 없어 실시하지 않고 있는 실정이다.In general, in order to increase efficiency by using a certain amount of fuel in a gasoline engine, the first thermal value must be high, and the second octane number must be increased. In order to increase the octane number, the addition of a catalyst for cracking and the prevention of knocking are required. There is a method of injecting anti-knocking agent for the bar. In addition to the conventional method, a small amount of water or alcohol is mixed into gasoline in order to increase the octane number. .

따라서 옥탄가를 높이기 위한 방법으로 전술한 안티 녹킹제의 주입을 가장 많이 사용하고 있는 바 문헌에 의하면 벤젠이 안티 녹킹제로서 우수한 효과가 있는 것으로 알려져 있으나 벤젠은 고가이므로 사용이 어렵고 알코홀과 더불어 실용성이 없는 반면에 저렴한 가격으로 구입이 가능한 경유에 벤젠이 다량 함유되어 있는 것으로 확인되고 있다.Therefore, as the method of increasing the octane number, the above-mentioned anti-knocking agent is most frequently used. According to the literature, benzene is known to have an excellent effect as an anti-knocking agent. However, benzene is expensive and difficult to use. On the other hand, it is confirmed that benzene is contained in diesel fuel which can be purchased at low price.

본 발명의 보조연료는 이와같이 벤젠을 다량 함유하고 있는 경유와 아세톤 및 크실렌을 혼합하여 구성한 것이므로 경유에 포함된 벤젠성분으로 인해 디젤엔진 (3)의 연소실에 유입되는 주연료의 옥탄가를 높일 뿐 아니라 완전연소를 촉진시켜 엔진의 효율을 높일 수 있게 되는 것이다.Since the auxiliary fuel of the present invention is composed of a mixture of acetone and xylene with diesel fuel containing a large amount of benzene, the benzene component contained in the diesel fuel not only increases the octane number of the main fuel introduced into the combustion chamber of the diesel engine (3) but also completely By accelerating the combustion it is possible to increase the efficiency of the engine.

이와같이 본 발명은 엔진 연소실의 전체적인 열량을 높여 엔진의 출력이 종래보다 현저하게 증가 되므로서 소량의 보조연료로 비싼 디젤유의 사용량을 절감하여 경제적으로 유용하며 매연이 대폭 감소되어 환경오염 방지에도 일익을 하게 되고 엔진의 수명도 연장시킬 수 있는 효과가 있다.As described above, the present invention increases the total heat of the engine combustion chamber, and thus the output of the engine is significantly increased compared to the prior art, thereby reducing the amount of expensive diesel oil as a small amount of auxiliary fuel, which is economically useful, and greatly reduces the smoke so that it also helps to prevent environmental pollution. It also has the effect of extending the life of the engine.
