Abstract
trata-se de um pistão de aço para motores a diesel de trabalho pesado projetados com recursos que aumentam adiabaticidade, reduzem o peso e aperfeiçoam o resfriamento passivo sem perda de densidade de potência. o pistão inclui um par de paredes de saia que se estende longitudinalmente a partir de uma coroa até uma extremidade inferior. as paredes de saia incluem uma pluralidade de cavidades dissipadoras de calor que se estende axialmente a partir da coroa até uma extremidade inferior da parede de saia. cada cavidade dissipadora de calor é preenchedo pelo menos parcialmente com um meio de resfriamento e é vedado. o pistão também inclui uma pluralidade de nervuras, em que cada uma é radialmente alinhada com um das cavidades dissipadoras de calor e se estende para dentro e para cima a partir de uma primeira extremidade de nervura em uma superfície interna da parede de saia até uma segunda extremidade de nervura na superfície interna da coroa.
