Technology of structural parts weight reduction for new Nissan's 4 cylinder HR MR engine

摘要

The concept of new Nissan's 4 cylinder 1.5L & 2.0L Gasoline Engine (HR15DE & MR20DE) is "high engine torque and low fuel consumption", "low NVH", "light weight and compact", "low cost". This paper describes weight reduction technologies of structural parts adopted to these engines. These engines can be achieved top level of weight benchmark by redesign of all components and systems, adoption of new technologies and integration of systems.
