Abstract

é fornecido um pistão de aço sem galeria para um motoro de combustão interna. o pistão tem um corpo de pistão monolítico incluindo uma parede superior formando uma superfície de combustão superior com primeira e segunda porções. a primeira porção estende anularmente ao longo de uma periferia externa da parede superior e a segunda porção define uma cuba de combustão. o pistão inclui ainda superfície sob a coroa localizada diretamente oposta à cuba de combustão com uma área de superfície bidimensional exposta permitindo contato de óleo de resfriamento. a área de superfície bidimensional exposta varia de 25 a 60 por cento de uma área em seção transversal definida por um diâmetro externo máximo do corpo de pistão. para aumentar ainda mais o resfriamento, uma porção da superfície sob a coroa é côncava ou convexa, de modo que óleo seja canalizado durante movimento de reciprocar do pistão a partir de um lado para o lado oposto do pistão.A galleryless steel piston is provided for an internal combustion engine. The piston has a monolithic piston body including an upper wall forming an upper combustion surface with first and second portions. the first portion extends annularly along an outer periphery of the upper wall and the second portion defines a combustion bowl. The piston further includes surface under the crown located directly opposite the combustion vat with an exposed two-dimensional surface area allowing cooling oil contact. The exposed two-dimensional surface area ranges from 25 to 60 percent of a cross-sectional area defined by a maximum outer diameter of the piston body. To further increase cooling, a portion of the surface under the crown is concave or convex so that oil is channeled during reciprocating movement of the piston from one side to the opposite side of the piston.
