ABSTRACT:
A device for sensing the amount of oil in oil pans of internal combustion engines is disclosed. In the device, a bottom plunger is fixedly mounted onto the inside bottom of an oil pan, with a contact terminal being mounted onto the top surface of the bottom plunger. A top plunger is movably positioned above the bottom plunger, with a contact terminal being mounted onto the bottom surface of the top plunger. The two contact terminals are normally spaced apart from each other in the event of the amount of oil being not less than a preferred amount. However, the two terminals are selectively brought into contact with each other in the event of an oil shortage in the oil pan. The device also has a means for selectively generating an alarm signal under the control of an ECU in the event of the two terminals being brought into contact with each other.
