Fretting fatigue becomes a typical failure mode for engine cylinder block caused by the increasing of the gas pressure and rotating speed, but the mechanism of fretting fatigue under diesel engine load condition hasn’t been systematic studied. In this paper, the fretting behaviors are mainly discussed by using fretting friction work parameter W and crack initiation location parameter G.

The three dimensional model of a 2-cylinder diesel engine block is established with the P ro/E software, and then the modal analysis of the engine block is carried out using finite element method with ANSYS software . Through the analysis, the inherent frequencies and mode shapes of the first 6 order modes are obtained respectively, and then are compared with the testing result; comparison shows the results of FEA estimation are in good agreement with those of testing which indicates the FEA results’ correctness. The results of the relative distribution of the vibration magnitude in the whole block are given, which provide necessary guides for the dynamic optimal design of the engine block.

This paper describes the traditional diesel engine cylinder block casting process on the basis, focusing on inline four-cylinder diesel engine cylinder block lost foam process design and optimization of application. Product pattern and pouring system model formed with expandable polystyrene beads, and assemble them into a model cluster, man can drying them after the model cluster dipping with the aid of manual or manipulator . Put the drying model cluster into the single sand box which with a negative pressure pumping system, a single dry sand rain-type sand system filling and compaction. Finally, to achieve the solidification of molten metal casting and forming under a certain vacuum.
