Abstract. This paper discusses the formulation of the problem of designing the cast parts block-crankcases engine in order to ensure its quality for the case study of cast iron parts of the cylinder block inline four-cylinder gasoline engine with the capacity of 1.4 dm3. Material Ch190B is gray cast iron with optional chemical composition, and sulfur – no more than 0.15 %, phosphorus – no more than 0.1 %, structure – perlite plate. The results obtained in this work confirm the conclusions about the possibility of reducing the metal content of the casting and changing the technical conditions of its manufacture. According to the results of the research, the developed recommendations are aimed at stabilizing the characteristics of the metal, reducing metal consumption, and changing the technical conditions for the defectiveness of this type of castings. Recommendations for changing the configuration of the partition in order to reduce the metal content of the casting and recommendations for changing the Technical Conditions for casting defects were stated for the casting block crankcase 4ChN12/14. For defects of discontinuity type, the maximum size was defined, and controlled places of their detecting were defined.

Keywords: CAD, CAE, block-crankcase, 3D model, casting defect.
