Abstract
PURPOSE:To prevent a crank bearing from seizure and a piston ring, etc. from wear owing to the lack of lubricating oil by detecting oil mist pressure in the crank chamber. CONSTITUTION:When oil mist pressure has been suddenly raised, voltage signals generated in an oil mist pressure detector (A) are added to an integrator 18. In consequence, because voltage of the differncen determined by time constants from the integrator 18 is generated between input voltage and output voltage, which is applied to a voltage comparator 16, at the same time when the voltage comparator 16 works, a gate element 9 is brought to be non-conductive. Therefore, a memory element 20 memorizes voltage appeared on a resistor 17 directly after ocurrence of trouble, after generation of abnormal pressure in the oil mist, when reference voltage decided by a variable resistor is overpassed by the voltage appeared on the resistor 17, it works a voltage comparator 21 and a relay 25 giving sound to a buzzer 27 at the same time when an alarm indicating light 29 is triggered to be lighted.
