Apparatus, device and computer implemented method for determining remaining life of engine oil in engine

An engine apparatus, comprising:

• an engine;
• a communication interface;
• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
• receive a reference model, the reference model being configured to be generated by associating reference engine profile data with reference engine oil lubrication properties, wherein the reference engine profile data is configured to be generated by determining reference engine parameters relating to a different operation conditions of the reference engine, and the reference engine oil lubrication properties are configured to be determined for the different operation conditions based on mechanical testing of an oil sample from the reference engine, wherein the mechanical testing of the oil sample comprises tribological lubricity test of the oil sample and the tribological lubricity test is configured to be evaluated based on friction test rig results;
• measure engine parameters relating to operation conditions of the engine of the engine apparatus;
• and
• determine remaining life of engine oil in the engine of the engine apparatus using the reference model and the engine parameters.

A server apparatus comprising:

• a communication interface;
• at least one processor;
• and
• at least one memory including computer program code;
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
• generate a reference model by associating the reference engine profile data with the reference engine oil lubrication data, wherein the reference engine profile data is generated by determining reference engine parameters of a reference engine and the reference engine oil lubrication data is determined based on mechanical testing of an oil sample from the reference engine, wherein the mechanical testing of the oil sample comprises tribological lubricity test of the oil sample and the tribological lubricity test is configured to be evaluated based on friction test rig results;
• and
• transmit the reference model to an engine apparatus for measuring engine parameters relating to operation conditions of an engine of the engine apparatus, and for determining remaining life of engine oil in the engine of the engine apparatus using the reference model and the engine parameters.
