Development of a Compact 3-Liter V6 Nissan Engine 920672

This paper presents a compact 3-liter DOHC V6 engine that has been newly designed for the Nissan Maxima. The aims set for the development of this new engine were to achieve a compact package and excellent fuel efficiency. The engine is built around a 4-valve-per-cylinder configuration with a high compression ratio and incorporates a variable valve timing control system, aerodynamic intake ports and roller rocker arms. These features enable it to provide good fuel economy while delivering excellent acceleration. The compact package has been achieved by adopting a 2-stage cam drive, narrow angle valve geometry and an optimized arrangement for the endpivot type hydraulic lash adjusters.
