The paper presents an experimental activity aimed at assessing the influence of a faster warm-up of the lubricant oil in a F1C (3 L) turbodiesel engine used both for light and heavy duty applications. The engine is ran on a dynamometer test bench and transient homologation cycles have been implemented considering different initial oil conditions. Lubricant and cooling thermal dynamics have been evaluated and their mutual thermal interactions have been discussed. In particular, an initial hotter oil showed fuel consumption and CO2 emissions saving. Harmful substances (CO, HC, NOx, particulate matter) have been measured too, displaying significant reduction mainly due to the modified engine temperature dynamics.

Abstract

The paper presents an experimental activity aimed at assessing the influence of a faster warm-up of the lubricant oil in a F1C (3 L) turbodiesel engine used both for light and heavy duty applications. The engine is ran on a dynamometer test bench and transient homologation cycles have been implemented considering different initial oil conditions. Lubricant and cooling thermal dynamics have been evaluated and their mutual thermal interactions have been discussed. In particular, an initial hotter oil showed fuel consumption and CO2 emissions saving. Harmful substances (CO, HC, NOx, particulate matter) have been measured too, displaying significant reduction mainly due to the modified engine temperature dynamics.
