I design and manufacturing deficiencies 1. The speed and power of some improved engine are significantly higher than that of the original engine. At high speed, the inertia force and stress of the engine are also increased, and cracks are easy to appear. 2. The structure of cylinder block is complex and the wall thickness is uneven. In some weak parts, the stiffness is low and cracks are easy to appear. 3. The stress concentration will be produced at the transition of different parts of the wall thickness between the processed and the unworked parts. When these stresses are superimposed with the residual stresses in casting, cracks will also easily occur. II Improper use 1. In the cold winter, no antifreeze is used or no cooling water is released according to the specified time (cooling water is cooled to normal temperature) after shutdown, which results in the freezing of the cooling water in the water jacket, or in the cold winter, the condensation of hot water ...
