eRocker System

Schaeffler’s eRocker System offers a unique and modular system for variability in the valvetrain to support the next generation of highly optimized internal combustion engines and hybrid powertrains. Supplemented by decades of experience and development, the eRocker System can be used for cylinder deactivation, valve deactivation, or special valve lift curves to achieve optimal combustion and system performance. As an integral part of the Schaeffler Smart OverRun System, which combines the eRocker System, Electric Cam Phaser, and a Belt Alternator Starter System, a cost-effective system solution is offered to reduce CO₂ and pollutant emissions.

Advantages:

• Increased recuperation for P0 and P1 Hybrids powertrains
• Up to 5% fuel savings for hybrid powertrains
• Additional CO₂ reduction through avoidance of rich purge operation
• Precise function and optimal switching times for all temperatures and engine speeds
• Simple integration
• Cost effective

Features:

• Electro-mechanical system – completely independent of pressurized engine oil supply
• Actuator without permanent magnets
• Modular design for cylinder or valve deactivation
• OBD/Actuator State-of-health diagnostic capability
• Flexible components for compensation of tolerances and thermal deflection
