Title in Portuguese

Modelamento do desgaste por deslizamento em anéis de pistão de motores de combustão interna.

Keywords in Portuguese

cilindro
contato aspero
rugosidade
tribologia

Abstract in Portuguese

O desgaste de anéis de pistão e cilindro foi modelado através de um programa computacional que calcula as pressões hidrodinâmicas e de contato rugoso agindo nas superficies deslizantes de contato. Os valores previstos de desgaste são comparados com um ensaio em dinamometro de um motor diesel.

Title in English

Modelling of the sliding wear on piston rings of internal combustion engines.

Keywords in English

asperity contact
cylinder
roughness

Abstract in English

The wear of piston rings and cylinder liner was modelled through a computer code that calculates the hydrodynamic and roughness contact pressures acting in the contact surfaces. The predicted wear is compared with a 750 hours dynamometer test of a medium duty diesel engine
