するようにしている。<< Prior Art >> Generally, in an engine, lubricating oil is exhausted to the outside of the engine along with blow-by gas during operation, or exhausted to the outside of the engine together with exhaust gas when the oil rises, so that the lubricating oil is consumed. For this reason, lubrication oil is replenished at regular intervals, but the consumption rate of lubricating oil varies depending on the engine operating conditions and individual engine differences. May run out of oil. Fuel oil mixes with fuel oil to dilute it, and metal powder scraped off due to wear in the rocking part and carbon generated by engine combustion mix with it, so its performance will increase with engine operation. Therefore, the lubricating oil is changed at a predetermined time.

るという問題があった。<Problems to be solved> However, even if an alarm device is installed and the oil reduction alarm is activated, it is not possible to prevent engine malfunction due to oil shortage unless lubrication oil is actually replenished. It could not be a countermeasure. In addition, the lubricating oil capacity stored in the oil pan is calculated based on the lubricating oil consumption rate and the lubricating oil deterioration rate of the engine so that the lower limit specified value can be maintained when the lubricating oil is replaced after a predetermined time of operation. However, since the lubricating oil consumption rates are not the same due to engine use conditions and individual engine differences, the oil amount in the oil pan may fall below the lower limit specified value before the specified time is reached. At this time,
Lubricating oil is replenished. However, if this replenishing amount is large, the amount of lubricating oil to be discarded at the time of lubricating oil replacement is large, which is uneconomical.

センサー(10)が配置してある。The crank chamber (8) of the engine (1) and the upper space of the sub tank (2) are balanced so that the lubricating oil can be efficiently supplied from the sub tank (2) to the oil pan (4) in a short time. It is connected by a pipe (9). FIG. 3 shows the relationship between the lubricating oil temperature and the flow-down time. In FIG. 3, the solid line indicates the crank chamber (8) and the upper space of the sub-tank (2) in communication with the balance pipe (9). It shows the case where the chamber (8) and the sub tank (2) are not communicated. From this graph, when the crank (8) and the upper space of the sub tank (2) are communicated, the internal pressure of the sub tank (2) is Since the pressure becomes the same as that in the chamber (8), the lubricating oil stored in the sub tank (2) flows down in a short time by the head pressure, but the crank chamber (8) and the sub tank (2) do not communicate with each other. In this case, it can be seen that the flow time becomes longer from the time when the internal pressure of the crank chamber (8) acts as a back pressure on the lubricating oil supply passage (3). Further, a temperature sensor (10) for detecting the oil temperature of the lubricating oil is arranged in the sub tank (2).

潤滑油量(Q)を算出する(ステップS4)。Then, as the engine (1) is operated, the lubricating oil stored in the oil pan (4) is consumed, and the lubricating oil surface (L) in the oil pan (4) falls below the lower limit specified value (L U ). When it reaches (step S1), it is judged whether or not the integrated time (T) integrated in the operating time integration part has reached the set time (T 0 ) for completely replacing the lubricating oil (step S2).
If the integrated time (T) is longer than the set time (T 0 ), a command is issued to change the oil (step

Since the viscosity changes depending on the oil temperature and the downflow time changes,
Based on the lubricating oil temperature from the temperature detection sensor (10), the time (M 0 ) for holding the solenoid valve (5) open is calculated (step
