Cooperation and cooperative design for a new automotive engine in the Renault group

Summary form only given. To develop a new engine, many contributors are involved in the design process, particularity when the car manufacturer is an international company. The presentation will give in a first part an overview on cooperation between various Renault members. After a description of main difficulties to exchange, we will focus on the main keys to success. A second part will be dedicated to the internal collaborative works within Renault corporate. It will be related to the different physical area which define or constrain the engine design. As a new engine is the results of many optimizations between different domains of physics, the process to get these optimizations will be described. Some focus will be given on the main difficulties encountered to get cooperative design. To finish, perspective on improvement will be mentioned.
