Description

피스톤 내연기관{PISTON INTERNAL COMBUSTION ENGINE}Piston Internal Combustion Engine {PISTON INTERNAL COMBUSTION ENGINE}

본 발명은 고압 연료를 분사 밸브로 공급하기 위한 커먼 레일을 구비하며 중유 작동에 적합한 피스톤 내연기관에 관한 것이다. The present invention relates to a piston internal combustion engine having a common rail for supplying high pressure fuel to an injection valve and suitable for heavy oil operation.

본 발명의 과제는 간단한 공간 절약형 수단으로 피스톤 내연기관의 이용 가능성을 높이는 것이다. An object of the present invention is to increase the availability of the piston internal combustion engine by a simple space-saving means.

상기 과제는 커먼 레일 내에 가열 소자를 장착함으로써 달성된다. 본 발명의 적용시 분사 밸브에는 항상 필요한 온도 및 그로 인해 필요한 점성을 갖는 연료가 제공될 수 있다. 내연기관은 정지 단계 후에도 문제없이 시동될 수 있다. 작동 중에도 요구되는 연료 점성을 지키는 것이 유리하다. This problem is achieved by mounting a heating element in the common rail. In the application of the invention the injection valve can be provided with a fuel which always has the required temperature and hence the required viscosity. The internal combustion engine can be started without problems even after the stop phase. It is advantageous to maintain the required fuel viscosity during operation.

바람직하게는, 상기 가열 소자가 커먼 레일의 중앙에 배치된다. 이로 인해, 공급된 열이 최적으로 이용된다. Preferably, the heating element is arranged in the center of the common rail. For this reason, the heat supplied is optimally utilized.

바람직하게는, 상기 커먼 레일은 갭을 포함하는 상태로 둘러 싸여있다. 이로 인해, 열 손실이 최소화될 수 있다. Preferably, the common rail is surrounded with a gap. Due to this, heat loss can be minimized.

또 다른 특징 및 장점은 종속 청구항 및 도면을 참고로 하는 실시예의 설명에 개시된다. 이 도면은 커먼 레일의 일부를 절결하여 도시하고 있다. Further features and advantages are disclosed in the description of the embodiments with reference to the dependent claims and the figures. This figure cuts and shows a part of common rail.

도면에는 관형 커먼 레일(1)이 도시되어 있다. 고압 연료를 수용하는 내부 공간(2) 내로 가열 소자(3)가 삽입된다. 상기 가열 소자는 도시된 실시예에서 고온 증기가 공급되는 관으로 형성된다. 커먼 레일(1)의 양단에는 각각 하나의 폐쇄 부품(4)이 배치된다. 상기 폐쇄 부품(4)은 내부 공간(2)을 압력 밀봉식으로 폐쇄한다. 도면에는 하나의 폐쇄 부품(4)만이 도시되어 있다. 각각의 폐쇄 부품(4)은 홀(5)을 가지며, 상기 홀에는 고온 증기의 순환을 유지하기 위한 파이프 라인(도시 생략)이 연결된다. 가열 소자(3) 및 홀(5)은 내부 공간(2)에 대해 압력 밀봉식으로 구현된다. 커먼 레일(1)은 공지된 방식으로 연결 부품(6) 내의 홀과 각각 하나의 연결 파이프 라인(7)을 통해 각각 하나의 분사 밸브(8)에 연결되어 있다. 2개의 연결 부품(6) 또는 하나의 연결 부품(6)과 폐쇄 부품(4) 사이에서 커먼 레일(1) 둘레에 갭이 마련되어, 각각 하나의 재킷관 부품(9)이 장착된다. The tubular common rail 1 is shown in the figure. The heating element 3 is inserted into the inner space 2 containing the high pressure fuel. The heating element is formed of a tube to which hot steam is supplied in the illustrated embodiment. One closed part 4 is disposed at each end of the common rail 1. The closure part 4 closes the interior space 2 by pressure sealing. Only one closure part 4 is shown in the figure. Each closed part 4 has a hole 5 to which is connected a pipeline (not shown) for maintaining the circulation of hot steam. The heating element 3 and the hole 5 are embodied in a pressure seal with respect to the internal space 2. The common rail 1 is connected to one injection valve 8 each via a hole in the connecting part 6 and one connecting pipeline 7 each in a known manner. A gap is provided around the common rail 1 between the two connecting parts 6 or one connecting part 6 and the closing part 4, in which one jacket pipe part 9 is mounted, respectively.

고온 증기가 흐르는 가열 소자 대신에 전기 가열 소자도 사용할 수 있다. An electric heating element may also be used instead of a heating element through which hot steam flows.

전술한 가열 소자에 의해, 장착 공간이 작을 때 커먼 레일(1) 내의 연료가 균일하게 예열되고, 그로 인해 확실한 엔진 시동 및 중유에 의한 엔진 작동이 이루어질 수 있다. 또한, 차가운 내연기관이 확실하게 작동되는 내연기관으로 되는 데 걸리는 시간이 단축되기 때문에, 피스톤 내연기관의 이용에까지 걸리는 시간이 단축된다.By means of the above-described heating element, the fuel in the common rail 1 is uniformly preheated when the mounting space is small, thereby ensuring reliable engine starting and engine operation by heavy oil. In addition, since the time taken for the cold internal combustion engine to become a reliably operated internal combustion engine is shortened, the time taken for the use of the piston internal combustion engine is shortened.

본 발명에 따르면, 분사 밸브에는 항상 필요한 온도 및 그로 인해 필요한 점성을 갖는 연료가 제공될 수 있고, 내연기관은 정지 단계 후에도 문제없이 시동될 수 있다. According to the invention, the injection valve can always be provided with a fuel having the required temperature and hence the required viscosity, and the internal combustion engine can be started without any problems even after the stop phase.
