関の漏油診断装置。 An oil level sensor detects the oil level in a leaking tank that collects fuel oil etc. leaking from an internal combustion engine, and the standard value of the oil level in the leaking tank expressed as a function of time is set to the initial oil level when the engine is stopped. A standard oil level setting means sets the corresponding constant value to a predetermined monotonically increasing curve corresponding to the operating conditions during engine operation, and the oil level after a predetermined time represented by the detection signal input from the oil level sensor. Subtract the above standard value from the actual measurement value to find the oil level deviation,
and an oil level determining means for determining whether or not this deviation is within a predetermined tolerance, so that an oil leakage abnormality in an internal combustion engine can be diagnosed based on the determination result of the oil level determining means. An oil leak diagnostic device for internal combustion engines characterized by:
