Abstract
um pistão para um motor de combustão interna e método de construção são providos. o pistão tem um corpo de pistão monolítico leve e robusto incluindo uma parede superior formando um vaso de combustão pendente radialmente para dentro de uma superfície de combustão superior anular. uma superfície de coroa inferior é formada em um lado de baixo dos vasos de combustão com pelo menos uma porção da superfície de coroa inferior sendo delimitada por porções de saia diametralmente opostas, saliências de pino e porções de suporte conectando as porções de saia nas saliências de pino. a superfície de coroa inferior delimitada tem uma área superficial abertamente exposta, vista ao longo de um eixo geométrico longitudinal central ao longo do qual o pistão alterna, provendo uma área de expansão com a qual óleo que está sendo esguichado ou borrifado pode entrar em contato direto para intensificar o resfriamento do pistão enquanto em uso. canais passantes que se estendem nas regiões superiores das saliências de pino podem ser providos para reduzir ainda mais o peso e facilitar o resfriamento.
