Structure Analysis and Improvement of Diesel Engine Block
The finite element analytical model of a diesel engine is established to analyze the stress,the flatness,the roundness and the rate of light leakage of the diesel engine block.The analysis result shows that the optimized scheme improves the bodys stress concentration and deformation obviously:the tensile stress between the upper cylinder sleeve shoulders spigot and the counter bore of cylinder head bolt decreases by 15% compares to the original diesel engine block.The maximum stress decreases obviously and the stress concentration region moves down slightly by changing the T type stiffener above the head of the block into rectangular stiffener; the flatness of the end surface of cylinder liner spigot decreases by 11.3%; the circularity and the rate of light leakage of each cross section on cylinder liner decreases obviously.
