Abstract: PROBLEM TO BE SOLVED: To enable the quality and level of lubricant to be well maintained by intermittently transferring some of the flow of lubricant passing through a second flow passage and periodically adding the fresh lubricant according to measurement results through a sensor provided which diagnoses the lubricant passing through the first flow passage. SOLUTION: An fluid duct 25 is connected to a high pressure lubricant line 8 upstream a lubricant filter 9 to measure the amount of lubricant EL in a lubricant well 5 of a diesel engine 2. A 3-way valve 26 is interposed in this duct 25. When this valve 26 in the OFF position, a some of the lubricant EL is led to a diagnostic cell 27 which includes a plurality of sensors 28 for diagnosing the quality or characteristic (such as temperature, pressure, relative permittivity, viscosity) of the lubricant. Then, if a controller 30 judges the quality of the diagnosed lubricant to be at or below a predetermined level, the valve 26 opens and closes regularly expelling the lubricant through a duct 31 to a reservoir 32, while fresh lubricant is pumped from a reservoir 40 and added to the lubricant line.

Abstract: A system for measuring the quality and level of lubricant in an engine lubricant reservoir includes valve means for selectively directing a portion of lubricant from the engine through a first conduit for return to the engine or through a second conduit for removal from the engine. Within the first conduit are one or more sensors for sensing the condition of the lubricant passing through the first conduit. The sensors are monitored by a controller which is operative selectively to cause the valve means to block the flow of lubricant through the first conduit and direct a portion of the lubricant through the second conduit based on the monitored conditions of the lubricant. Also, the controller directs a supply of fresh lubricant to the engine in response to the lubricant in the engine lubricant reservoir dropping below a predetermined level. The lubricant flowing through the second conduit may either be stored in a lubricant reservoir and if desired subsequently intermittently mixed with the fuel in the fuel tank, or caused to flow directly to the fuel tank on command of the valve means by the controller which limits the amount of lubricant that can be added to the fuel tank so as not to exceed a predetermined lubricant/fuel ratio for the engine.

Abstract: A system (1) for measuring the quality and level of lubricant in an engine lubricant reservoir (5) includes valve means (26) for selectively directing a portion of lubricant from the engine (2) through a first conduit (25) for return to the engine or through a second conduit (31) for removal from the engine. Within the first conduit are one or more sensors (28) for sensing the condition of the lubricant passing through the first conduit. The sensors are monitored by a controller (30) which is operative selectively to cause the valve (26) means to block the flow of lubricant through the first conduit and direct a portion of the lubricant through the second conduit (31) based on the monitored conditions of the lubricant. Also, the controller (30) directs a supply of fresh lubricant to the engine in response to the lubricant in the engine lubricant reservoir dropping below a predetermined level. The lubricant flowing through the second conduit may either be stored in a lubricant reservoir (32) and if desired subsequently intermittently mixed with the fuel in the fuel tank (11), or caused to flow directly to the fuel tank on command of the valve means by the controller which limits the amount of lubricant that can be added to the fuel tank so as not to exceed a predetermined lubricant/fuel ratio for the engine.
