Embodiment Construction

[0011] Such as figure 2 As shown, the sensor includes a motor G, a friction head 9, and a oil measuring tube 7. The friction head 9 is set in the oil measuring tube 7, and the corresponding parts of the friction head 9 and the inner wall of the oil measuring tube 7 are made into corresponding cone shapes, and the taper surfaces are matched. contact; the rotating shaft 10 of the friction head 9 is provided with a tensioning device composed of a shaft sleeve 2 and a compression spring 4, so that the friction head 9 is in close contact with the inner wall of the oil measuring tube 7, and the friction head 9 can be adjusted by adjusting the nut 5. Pulling force; the rotating shaft 10 is connected with the motor G through the coupling 1, and the contact surface between the coupling 1 and the rotating shaft 10 is made into a prism or a spline, so that it can move axially to cooperate with the adjustment of the adjusting nut 5.

[0012] During use, the sensor is inserted in the engi...

Abstract

The invention relates to a diesel engine oil aging monitor which comprises a sensor and a detecting circuit, wherein the sensor comprises a motor, a friction head and an oil measuring pipe, wherein the friction head is arranged inside the oil detecting circuit and is attached with the inner wall of the oil measuring pipe; the rotation shaft of the friction head is connected with the motor which is connected with the detecting circuit. When the oiliness of engine oil fell down to a certain degree, the friction head builds up, the motor burden builds up to the set valueú¼the circuit rotatesú¼the guiding lamp sends the alarm guide.

Description

technical field [0001] The invention relates to an internal combustion engine, which is a monitoring device for detecting the service life of the engine oil of the internal combustion engine. Background technique [0002] Engine oil plays the role of lubrication in the internal combustion engine. In the absence of engine oil, the internal combustion engine will produce faults such as overheating, cylinder scuffing, and severe wear of parts, which will damage the machine. At present, in the internal combustion engine, the engine oil pressure is mainly monitored, and when the oil pressure drops to a certain value, a warning indication is issued. However, after a certain period of use, the physical properties of the engine oil, that is, the lubricity, will decrease, which will affect the working performance of the internal combustion engine. The current method is to regularly replace the engine oil, or to judge the quality of the engine oil based on experience, which is prone ...
