Development in Casting Technology of Light Weight MMC Cylinder Blocks

摘要

Generally aluminum diecasting is superior in productivity compared to other casting processes, but inferior in strength due to casting defects. As a result of application of MMC (=Metal Matrix Composite) to all aluminum cylinder blocks, high quality diecasting which consists of directional solidification and melt laminar flow was developed. This technology makes it possible to re-design the base engine for high performance with the narrowest bore-to-bore distance in the world..
