◆Development concept |
Against the backdrop of environmental issues around the world, fuel efficiency improvement activities of the
gasoline engine vehicle by using supercharging downsizing turbo has been trended. A number of research papers have been established as themes of VGT(Variable Geometry Turbo), VGS(Variable Geometry System) and VG(Variable Geometry). However, because of the excessive performance and high cost, it is not as popular as diesel engine turbo cars. So atect will realize high performance and low cost by doing alloy development with the performance more than HK30 less than Inconel713C and production innovation by fully using IT technology, and is going to contribute the spread of gasoline engine cars and environmental problems. |
