The detachable means is for example a screw connection. The filtered foreign substances are accumulated on the oil filter 34 c. The oil filter 34c is of a Y-type or a cone type, for example. The filter 34c needs to be replaced periodically to avoid impurities from plugging the oil filter 34 c. Further, in order to facilitate replacement of the oil filter 34c, a valve may be provided at each of positions upstream and downstream of the installation position of the oil filter 34c on the oil circulation pipe 31 c.
A fuel level sensor 40c is provided on the sub-tank 20c for detecting the level of the oil (fuel level) in the sub-tank 20 c.
The control unit 50c is in communication with the engine 1c, the oil circulation pump 33c, and the oil level sensor 40c, respectively, and is configured to acquire a real-time rotation speed and a real-time fuel consumption of the engine 1c and an oil level of the secondary fuel tank 20c, and control the operation of the circulation pump 33c based on the real-time rotation speed, the real-time fuel consumption, and the oil level.
The process of the control unit 50c controlling the operation of the oil circulation pump based on the real-time rotation speed, the real-time fuel consumption amount, and the oil level is:
first, a real-time fuel consumption Z is calculated based on a real-time rotation speed x and a real-time fuel consumption y,
z is m x + n y, wherein m and n are constants,
then, the oil replenishment and oil cleaning filtration time is calculated from the oil consumption Z and the oil level.
Finally, the oil circulation pump 33c is controlled to operate according to the oil replenishing and oil cleaning and filtering time, so that the oil replenishing and oil cleaning and filtering of the engine oil tank 10c are performed.
The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.
For example, although the liquid level sensor is provided in each of embodiment 4 and embodiment 5, the liquid level sensor may not be provided in actual use.
