The aim if this paper is the analysis of a lubrication circuit adopting two simulation models to study the influence of three different lubrication oils. First, the oils pump performance were analyzed with a tri-dimensional simulation model, realized with the commercial code PumpLinx r, which allowed to obtain the performance curves of the oil pump, varying the oils. Then the lubrication circuit was studied with a 1D model, realized with the commercial code LMS AMESim r, and the behaviour of the lubrication circuit was analyzed in terms of pressure drops and components oil consumption. The adopted oils were: 0W30; 5W40 and10W60. In previous activities, both models showed good correlation with experimental data. Analyzing the models results, it was noted that the pressure behavior in the lubrication circuit is highly influenced by the oil, especially for low engine speed and high temperatures. The adopted methodology, that couples mono-dimensional and tri-dimensional models, allowed to analyze the oil influence in a lubrication circuit, avoiding excessive computational cost, but with an acceptable accuracy (C) 2015 The Authors.
