This study has been begun to find the cause of 3-cylinder diesel engine piston damage. The piston reciprocating motion for high speed under high temperature and high pressure should use the material featuring heat - resistance, wear - resistance and strong for heat expansion.
Material analysis to verify that the proper material were used, damage to the piston of the engine through a liquid penetrant inspection to check the defective portion was the progress of the defect size and defect was confirmed. Based on the that result we changed the shape of the piston bore, the inner edge and thickness change of the model was designed to reinforce the strength.
We used finite element method to compare existing piston with engineering product to an original product of stress distribution. We also compared that result with existing product for verification of reinforced strength model.
Of the result of analysis, the comparison value of von Mises stress and S22 stress is decreased. The changed shape of the piston bore model is verified to be the safest structurally.
