ABSTRACT:
An engine oil level detector, which includes a casing, a cover covered on the casing and defining two communicated air chambers, a diaphragm covered on the air chambers of the cover, the diaphragm having first and second tubular coupling portions, an electromagnetic valve mounted in the casing and controlled to reciprocate the first tubular coupling portion, a solenoid switch controlling a signal lamp, a magnet moved with the second tubular coupling portion to turn on/off the solenoid switch, and a suction tube connected between the first air chamber and the engine oil tank in a vehicle engine, wherein the magnet is moved with the second tubular coupling portion of the diaphragm toward the solenoid switch, causing the solenoid switch to be turned off when the oil level in the engine oil tank drops below the suction tube and the electromagnetic valve is turned on; the magnet is moved with the tubular coupling portion of the diaphragm away from the solenoid switch, causing the solenoid switch to be turned on when the oil level in the engine oil tank surpasses the suction tube and the electromagnetic valve is turned on.
