雷诺卡车公司新设计了一款4缸5 L发动机,由于一些零部件采用3D打印技术,其重量减少了120 kg,并且相关零部件的耐久性已经得到测试验证。目前为止,雷诺卡车公司的工程师已虚拟设计了完整的发动机,其摇臂和凸轮轴轴承盖采用金属3D打印制造,并在台架上顺利地对这款欧Ⅵ发动机进行了600 h的测试。雷诺卡车项目经理达米安·勒马森表示:“该项目的目的,是为
Renault Trucks has newly designed a 4-cylinder 5-L engine that has been reduced in weight by 120 kg due to some components using 3D printing technology and the durability of the related components has been tested and verified. So far, Engineers at Renault Trucks have virtually engineered a complete engine with metal and 3D rocker and cam shaft bearing caps, which have been tested on the rig for 600 h on the Euro VI. Damian Lemasson, Renault Truck Project Manager, said: ”The purpose of this project is to
