The invention discloses an electromagnetic control valve for a diesel engine lubricating system, and relates to the field of electromagnetic valves, the electromagnetic control valve is simple in structure, by adjusting the matching relation between electromagnetic control valve structures, an oil discharge port is formed in the front end of a valve sleeve, two annular grooves are formed in the peripheral side of the valve sleeve, and a first oil outlet and a second oil outlet are formed in the second annular groove; and meanwhile, the sizes of the two oil outlets are adjusted, so that the oil quantity of lubricating oil discharged from the oil pump adjusting cavity through the second oil outlet is larger than the oil quantity of the lubricating oil flowing into the oil pump adjusting cavity through the first oil outlet from the oil inlet. The device is wide in hydraulic oil quantity adjusting range, high in precision and sensitive in reaction; when the electromagnetic valve is powered off and fails, the elec
