Abstract
This paper analyzes the cooling conditions of articulated piston and their impact on the piston performance. In order to evaluate the piston cooling optimization two configurations of cooling oil jet (single and double) are evaluated on a real time measurement test, together with two articulated piston skirt configuration (single and extended).
The results show the influence of engine valves location in the temperatures near the piston top and the influence of cooling oil jet in piston lower part temperatures. The results also show the extended tray efficient behaviour in removing heat from piston undercrown when compared to double jet-single tray configuration.
