Description

선박용 디젤 내연 기관의 윤활유 시스템 및 그 작동 방법{LUBRICATING OIL SYSTEM OF A MARINE DIESEL INTERNAL COMBUSTION ENGINE AND METHOD FOR OPERATING THE SAME}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubricating oil system for a marine diesel internal combustion engine,

본 발명은 선박용 디젤 내연 기관의 윤활유 시스템과 그 작동 방법에 관한 것이다.The present invention relates to a lubricating oil system for a marine diesel internal combustion engine and a method of operating the same.

실무에 따른 선박용 디젤 내연 기관의 윤활유 시스템은, 윤활유를 제공하기 위한 윤활유 저장조와, 윤활유를 상기 윤활유 저장조의 밖으로 전달하기 위해 선박용 디젤 내연 기관에 의해 구동되는 윤활유 펌프, 그리고 상기 윤활유 펌프에 의해 제공되는 윤활유 압력을 제한하는 윤활유 밸브를 포함한다. 현재, 실제 알려진 윤활유 시스템에서, 상기 윤활유 펌프는 선박용 디젤 내연 기관에 의해 기계적으로 구동된다. 상기 윤활유 밸브는, 선박용 디젤 내연 기관의 전체 회전 속도 범위에 걸쳐서 일정한 윤활유 압력을 보장하는 기계식 밸브이다. 윤활유 압력이 너무 높은 경우, 윤활유를 내연 기관을 우회하여 윤활유 저장조 안으로 배출하기 위하여 기계식 윤활유 밸브가 개방되고, 이에 따라 윤활유 압력이 제한된다.A lubricating oil system of a marine diesel internal combustion engine according to the present invention comprises a lubricating oil reservoir for providing lubricating oil, a lubricating oil pump driven by a marine diesel internal combustion engine for delivering lubricating oil to the outside of the lubricating oil reservoir, And a lubricating oil valve for restricting the lubricating oil pressure. Currently, in a known lubricating oil system, the lubricating oil pump is mechanically driven by a marine diesel internal combustion engine. The lubricating oil valve is a mechanical valve that ensures a constant lubricating oil pressure over the entire rotational speed range of the marine diesel internal combustion engine. If the lubricating oil pressure is too high, the mechanical lubricating oil valve is opened to bypass the internal combustion engine and into the lubricating oil reservoir, thereby limiting the lubricating oil pressure.

선박용 디젤 내연 기관의 윤활유 시스템을 보다 효과적으로 작동시키고 소비량 이점을 구현할 필요가 있다.There is a need to more efficiently operate the lubricating oil system of marine diesel internal combustion engines and to realize consumption advantages.

이러한 점으로부터 시작하여, 본 발명은 신규 타입의 선박용 디젤 내연 기관의 윤활유 시스템과 그 작동 방법의 창출이라고 하는 과제에 기초한 것이다.Starting from this point, the present invention is based on the task of creating a lubricating oil system for a new type of marine diesel internal combustion engine and its operating method.

이러한 과제는 청구항 1에 따른 윤활유 시스템에 의해 해결된다. 본 발명에 따르면, 상기 윤활유 시스템은 윤활유 밸브를 작동시키기 위한 제어 장치를 포함하고, 상기 제어 장치는, 선박용 디젤 내연 기관의 회전 속도에 따라, 선박용 디젤 내연 기관의 회전 속도에 좌우되는 윤활유 압력 설정값을 결정하며, 상기 윤활유 압력 설정값에 따라, 상기 윤활유 압력 설정값을 제공하기 위해 상기 윤활유 밸브를 작동시키는 것이다.This problem is solved by a lubricating oil system according to claim 1. According to the present invention, the lubricating oil system includes a control device for operating the lubricating oil valve, and the control device determines, based on the rotational speed of the marine diesel internal combustion engine, a lube oil pressure set value And operates the lubricating oil valve to provide the lubricating oil pressure set value in accordance with the lubricating oil pressure set value.

본 발명에 의하면, 요건을 충족시키는 선박용 디젤 내연 기관의 윤활유 압력 공급이 제공된다. 선박용 디젤 내연 기관의 회전 속도에 따라, 상기 제어 장치는 윤활유 압력 설정값을 결정하고, 상기 윤활유 압력 설정값에 따라, 상기 윤활유 압력 설정값을 조정하거나 또는 제공하기 위해 상기 윤활유 밸브를 작동시킨다. 특히, 선박용 디젤 내연 기관의 회전 속도가 낮은 경우, 이에 따라 소비량 이점이 가변적인 윤활유 압력을 통해 구현될 수 있다.According to the present invention, lubricating oil pressure supply of a marine diesel internal combustion engine that meets the requirements is provided. Depending on the rotational speed of the marine diesel internal combustion engine, the control device determines a lubricant pressure set point and activates the lubricant valve to adjust or provide the lubricant pressure set point in accordance with the lubricant pressure set point. Particularly, when the rotational speed of the marine diesel internal combustion engine is low, the consumption amount advantage can be realized through the variable lubricating oil pressure.

상기 윤활유 밸브는 전기적으로 조정 가능한 윤활유 밸브이다. 전기적으로 조정 가능한 윤활유 밸브를 이용함으로써, 상기 제어 장치로부터 발원하는 윤활유 밸브의 조정은, 회전 속도에 좌우되는 윤활유 압력 설정값에 특히 유익하게 맞춰질 수 있다.The lubricating oil valve is an electrically adjustable lubricating oil valve. By using an electrically adjustable lubricating oil valve, the adjustment of the lubricating oil valve originating from the control device can be particularly beneficial to the lubricating oil pressure set point which is dependent on the rotational speed.

유익한 개선예에 따르면, 선박용 디젤 내연 기관의 회전 속도의 함수로서 상기 윤활유 압력 설정값을 결정하고 상기 윤활유 압력 설정값의 함수로서 윤활유 밸브의 위치 설정값을 결정하기 위하여, 상기 제어 장치에 특성 곡선 또는 특성 맵이 저장되어 있고, 이를 통해 윤활유 압력 설정값이 제공될 수 있다. 이러한 방식에서, 적절한 윤활유 압력 설정값과 상기 윤활유 압력 설정값에 매칭되는 윤활유 밸브의 위치 설정값이, 선박용 디젤 내연 기관의 회전 속도의 함수로서 용이하게 그리고 신뢰 가능하게 결정될 수 있다. 유익한 추가적인 개선예에 따르면, 상기 제어 장치는 윤활유 밸브의 작동, 특히 윤활유 밸브의 위치 설정값을 기반으로 발현되는 실제 윤활유 압력을 상기 윤활유 압력 설정값과 비교하고, 상기 실제 윤활유 압력과 상기 윤활유 압력 설정값 사이에 편차가 있는 경우에, 상기 제어 장치는, 상기 실제 윤활유 압력이 상기 윤활유 압력 설정값에 가까워지도록, 상기 윤활유 밸브의 작동을 바람직하게는 폐루프 제어 방식으로 조정한다. 상기한 유익한 다른 개선예에 의하면, 윤활유 압력을 한층 더 정확하게 조정하기 위해, 윤활유 압력의 폐루프 제어가 제공된다.According to an advantageous improvement, in order to determine the lubricating oil pressure set point as a function of the rotational speed of the marine diesel internal combustion engine and to determine the set point of the lubricating oil valve as a function of the lubricating oil pressure set point, A characteristic map is stored, through which a lubricant pressure setpoint can be provided. In this way, the appropriate lubricating oil pressure setpoint and the set point of the lubricating oil valve that matches the lubricating oil pressure setpoint can be determined easily and reliably as a function of the rotational speed of the marine diesel internal combustion engine. According to an advantageous further improvement, the control device compares the actual lubricating oil pressure, which is expressed on the basis of the operation of the lubricating oil valve, in particular the position of the lubricating oil valve, with the lubricating oil pressure setpoint, If there is a deviation between the values, the control device preferably adjusts the operation of the lubricating oil valve to a closed-loop control such that the actual lubricating oil pressure is close to the lubricating oil pressure set point. According to another advantageous improvement described above, closed loop control of the lubricating oil pressure is provided in order to adjust the lubricating oil pressure more accurately.

본 발명에 따른 선박용 디젤 내연 기관의 윤활유 시스템의 작동 방법은 청구항 6에 규정되어 있다.A method for operating a lubricating oil system of a marine diesel internal combustion engine according to the present invention is defined in claim 6.

본 발명의 다른 개선예는, 종속 청구항과 이하의 상세한 설명을 통해 확보된다. 도면을 통해 본 발명의 예시적인 실시형태를 보다 상세히 설명하지만, 이 도면에 제한되는 것은 아니다.Other improvements of the invention are ensured through the dependent claims and the following detailed description.

The pressure sensor described above may be attached to the supply line 16, for example, on the downstream side of the lubricating oil pump 16 or on the downstream side of the filtration device 21. [

본 발명에 따르면, 선박용 디젤 내연 기관(10)의 회전 속도에 따라, 선박용 디젤 내연 기관(10)의 회전 속도에 좌우되는 윤활유 압력 설정값이 결정되고, 상기 윤활유 압력 설정값에 따라, 상기 윤활유 압력 설정값을 조정하기 위해 윤활유 시스템의 윤활유 밸브(14)가 작동된다.According to the present invention, a lubricating oil pressure set value, which is dependent on the rotational speed of the marine diesel internal combustion engine 10, is determined in accordance with the rotational speed of the marine diesel internal combustion engine 10, and in accordance with the lubricating oil pressure set value, The lubricating oil valve 14 of the lubricating oil system is operated to adjust the set value.
