Optimized Power Cell Unit in IC Engine - Design for Light-Weight and High-Strength Piston and Connecting Rod

摘要

Rising gas prices at the fuel station, stronger emission requirements at the tail pipe have required more and more fine-tuning of the internal motor components. To support the customers in this difficult task, MAHLE has developed a Power Cell Unit (PCU). The newly introduced lightweight PCU with the MAHLE-patented ECOFORM piston, an optimized pin and high-strength-material connecting rod offers the customer a complete system that is focused on less reciprocating masses, lower friction and better NVH. The PCU as a unit has been developed for each and every component as well as the interaction of all these components to additionally benefit the customer with less program management, organization, logistic and reduction of development time because all parts are made in-house by MAHLE. An example using a conventional PCU in production versus a weight-optimized version is provided for comparative purposes.
