Engine Oil Lubrication Monitoring and Protection System

Abstract

The invention relates to an engine oil lubrication monitoring and protecting system. The system comprises a pressure sensor, an engine oil protector and at least two ignitors, wherein an ignition coil and a one-way isolation diode are arranged in each ignitor, the primary part of the ignition coil is connected with a negative pole of the one-way isolation diode, a positive pole of the one-way isolation diode of the ignitor is connected with one end of a flameout switch, and the other end of the flameout switch is grounded; a revolution speed signal collecting line of each ignitor is connected with an engine oil protector and used for providing engine revolution speed signals for the engine oil protector; the pressure sensor is connected with the engine oil protector, and the engine oil protector is used for receiving the engine revolution speed signals and engine oil pressure signals, comparing the engine revolution speed signals with a set revolution speed value, comparing the engine oil pressure signals with a set pressure value and controlling an engine to stall and stop. According to the engine oil lubrication monitoring and protecting system, the condition that moving parts such as an engine crankshaft and the like lock and damage the engine due to lack of engine oil or excessive low lubricating oil pressure and poor lubrication can be prevented.

Description

technical field [0001] The invention relates to an engine protection device, in particular to an engine oil lubrication monitoring and protection system. Background technique [0002] When the engine is working, many transmission parts make high-speed relative motion in a small gap, such as crankshaft main journal and main bearing, crank pin and connecting rod bearing, cam journal and cam bearing, piston, piston ring and cylinder wall , each movement pair of the gas distribution mechanism and the transmission gear pair, etc. Although the working surfaces of these parts are finely machined, they are uneven when viewed under magnification. If these surfaces are not lubricated, intense friction will occur between them. The dry friction between the metal surfaces not only increases the power consumption of the engine and accelerates the wear of the working surface of the parts, but also may burn the working surfaces of the parts due to the heat generated by the friction, so th...

Problems solved by technology

The engine can run normally when the oil level is higher than the limit level of the oil sensor, but if the oil pump leaks or the lubricating oil channel is blocked, the engine crankshaft and other key lubricating parts cannot form an oil film or the oil film ruptures due to the low oil pressure, which will cause engine lubrication. Bad and locked, engine damage occurs
