On January 12, 2015, it was learned from the Yulin Municipal Government that Yuchai City's 2014 scientific and technological progress was awarded for the “Key Technology Development and Application of Engine Manufacturing Quality Engineering†and the “Technology Study on Iron-based Sand-Coated Casting Cylinder Blocks†project submitted by Yuchai. Award first prize. The “Key Technology Development and Application of Engine Manufacturing Quality Engineering†project is aimed at environmental governance and environmental protection requirements. It focuses on key technologies for quality control in the R&D and manufacture of energy-saving and emission-reducing engines, and systematically studies engine R&D design, casting, processing, The key technologies of assembly are thus formed to suit the manufacturing industry's manufacturing quality control technology. The purpose is to improve the reliability life of the engine, reduce the quality loss rate, and break through the bottleneck of the quality control technology of the engine manufacturing process. The project “Technology for the Iron-Type Sand-Coated Casting of Cylinder Blocks†was the first in China to produce cylinder blocks using iron-type sand-covering technology, and created a new field of cylinder block production. The products produced have the advantages of high dimensional accuracy, good mechanical properties, labor saving, materials and equipment, and low production costs. The wall thickness of the D30 cylinder block produced by the technology can be reduced by 15%, the weight is reduced from 131kg to 126kg, and the weight is reduced by 5kg/set, achieving lighter weight and lowering the production cost; and the casting yield reaches more than 83.75%, which is more than the original sand casting. The process has increased by 22%; the casting scrap rate has dropped by 2% compared to the static pressure auto-moulding body scrap rate.
