1. Simulação computacional em camisas de motor construídas em liga de alumínio silício
Automotive cylinder liners are mechanical components with the function of internal coating of the cylinder automotive engines. The liners have been made of cast iron, which meets the necessary requirements. The replacement of parts made of steel/ cast iron in aluminum alloys has been made with advantages not only in reducing weight as well as fuel consumptio

2. Internal turning for cylinder liners made of centrifuged gray cast iron / Torneamento interno de cilindros automotivos de ferro fundido cinzento centrifugado
This investigation describes and shows an unprecedented machining process to be used for manufacturing cylinder liners, which are very important parts used in aluminum engine blocks for automobiles. There are few known companies that manufacture this kind of component, and until now, all of them use a boring process to machine the internal diameter of the cy

3. THE USE OF X RAY DIFFRACTION TO DETERMINE THE RESIDUAL STRESS INDUCED BY THE COLD ROLLING PROCESS IN A CYLINDER LINER OF A DIESEL ENGINE / O uso da difração de Raios-X para determinação da tensão residual induzida pelo processo de roleteamento em uma camisa de cilindro de motor diesel
Neste trabalho, comprovou-se através do teste de fadiga que a camisa de cilindro pode ter sua resistência à fadiga elevada pela tensão residual compressiva induzida pelo roleteamento do raio de concordância. Utilizando a metodologia do Planejamento de Experimentos (DOE), criou-se um experimento para estudar a contribuição individual na elevação da t

4. Modificação da superficie de borracha EPDM tratada por meio de processos a plasma frio
The surface of vulcanized ethylene-propylene diene monomer (EPDM) rubber is highiy hydrophobic and so it is not suited for a number of potential applications, in particular, for to the polyurethane liner of solid propellants used in missiles and rocket. In this case, plasma treatment is a very attractive process to improve their adhesive properties. The EPDM

5. Modelamento do desgaste por deslizamento em anéis de pistão de motores de combustão interna. / Modelling of the sliding wear on piston rings of internal combustion engines.
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
