Cooling Of Automotive Pistons: Study Of Liquid-Cooling Jets

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">The development of more efficient and powerful internal combustion engines requires the use of new technologies. In general, the pistons of these engines are subjected to higher heat fluxes in the: ring zone, oil gallery, piston undercrown. This higher heat flux in the rings zone demands the use of new constructive

Studies of a Heat-Pipe Cooled Piston Crown

Journal of Engineering for Gas Turbines and Power, 1999
Designing pistons with effective cooling is crucial to preventing piston failure and improving engine service life. A piston design that incorporates the heat-pipe cooling technology may provide a new approach that could improve the thermal-tribological performance of heavy-duty diesel engine pistons.
