Manufacturing Methods for a New-Generation Lightweight 3-Liter V6 Nissan Engine
This paper describes various methods and technologies that have been newly implemented for manufacturing a new-generation V6 engine with high product quality and at low cost. This new engine, the VQ30DE, is mounted in the latest Maxima model. Design for manufacturability was pursued through concurrent engineering between the product development and production engineering departments from the initial stage and included the development of a new system for evaluating productivity. A new engine plant was also constructed which adopts new automation facilities to minimize production time. These new approaches support the production of a high-quality, high-reliability engine.
