High-precision 3D scanning of an internal combustion engine
3D scanning and modeling helped to create a drawing and a three-dimensional model of the engine to improve its design.
In car racing, a lot depends on the combination of the skills of the pilot and the technical perfection of the car. Designers are struggling with the problems of body aerodynamics, weight reduction of the car and strive to get maximum power from the engine.
The cylinder block of a serial internal combustion engine was delivered to the Glavkonstruktor office in St. Petersburg. The specialists faced a difficult task — to create a drawing and a three-dimensional model of the new engine, using the reverse engineering method.
The internal combustion engine cylinder block has many complex curved surfaces and hidden cavities: oil channels and cooling channels. To scan the internal elements, the block would have to be sawn into pieces. Therefore, we decided to digitize the outside, and add oil channels and cooling channels "manually".
To begin with, the block was cleaned of accumulated dirt. Then markers for automatic stitching of scans were glued to its surface and a matting spray was applied. With it, excessively dark or glare areas are digitized more accurately.
The RangeVision Standard Plus 3D scanner provides high accuracy (from 0.05 to 0.35 mm, depending on the scanning area) and high speed. Digitization together with the preparation of the product took only 4 hours. The received block scan data was processed in the RangeVision ScanCenter program. During the processing, noise, irregularities and other artifacts were removed, and then verification was performed — compared with the original scan.
Based on the polygonal model, a solid-state model was built, suitable for further refinement of geometry in a CAD system. Specialists of Glavkonstruktor LLC experimentally determined the shape and location of the necessary cavities of oil channels and cooling channels and added them to the 3D model of the unit.
According to the solid—state model of the internal combustion engine cylinder block, the drawings of the new engine were completed for further manufacture — casting — and sent to the customer.
