Free-Piston Engine
Peter Van Blarigan
Sandia National Laboratories
Goals of the Free-Piston Engine Research Prototype
–
To study the effects of continuous operation (i.e. gas exchange) on indicated thermal efficiency and emissions at high compression ratios (~20-40:1)
–
Concept validation of passively coupling the opposed free pistons via the linear alternators connected to a common load to maintain piston synchronization
–
Proof of principle of electronic variable compression ratio control
