An apparatus and method for determining lubrication contamination or deterioration in an engine or a lubricant system of an engine can include at least one sensor provided in the lubricant system. The sensor can sense an aroma of a lubricant or the air around the lubricant to measure a chemical composition or an aromatic. The sensed chemical composition or aromatic can be compared to a baseline or threshold to determine a particular contamination type or deterioration level of the lubricant.

An apparatus comprising: an identity determiner configured to determine an identity of a removable fluid container; a characteristic determiner configured to obtain a first characteristic based on testing the fluid of the fluid container; a data obtainer configured to obtain a second characteristic based on the identity; and a processor configured to control a fluid provider to provide fluid from the removable fluid container based on the comparison of the first characteristic and the second characteristic.

Methods and systems are provided for an oil diagnostic. In one example, a method may include intrusively increasing an oil pump displacement to determine if an internal oil leak is occurring. The method may further include adjusting a parking routine to determine if an external oil leak is determining.

A hydraulic circuit includes a hydraulic pump configured to supply lubricating oil, a resisting apparatus configured to maintain an oil pressure of the lubricating oil supplied from the hydraulic pump, an oil supply channel configured to guide the lubricating oil from the hydraulic pump to the resisting apparatus, and an optical detector configured to measure a degree of contamination of the lubricating oil flowing through the oil supply channel.

A monitoring device of an oil flow mixed with air, including a tubular element coupled with at least one first and one second photoelectric sensor that emit a radiation along a first and a second optical line respectively, the tubular element being at least partially transparent to the radiation, the first and the second photoelectric sensor being mounted on the tubular element so that the first and the second optical line are mutually angled.

Disclosed is a monitoring apparatus for monitoring a state of wear of a component of a reciprocating piston internal combustion engine wherein an oil collection device is provided for the collection of lubrication oil from the cylinder so that a predetermined measured quantity of lubrication oil is suppliable from the cylinder to a measurement device.

A working fluid monitoring system for monitoring a working fluid of working fluid system of a piece of equipment is provided. The working fluid monitoring system can include a filter member having an inlet, an outlet, and a filter media disposed between the inlet and the outlet. The filter member can be configured to permit fluid communication of the working fluid of the working fluid system from the inlet, through the filter media, and out the outlet of the filter member. A sensor is in operable communication with the working fluid within the filter member and is configured to monitor in situ a parameter of the working fluid and/or the working fluid system.
