Technology
Project objective: Development of 1 KWe electric generator
based on linear, free piston engine that drives a permanent
magnet linear electric generator.
Technology (cont’d)
Description of the technology under development: The
IC engine is a two-stroke, spark ignited system, with port
scavenging, resonant cylinder recharging, and managed
exhaust gas recirculation (EGR).
The linear motion electric generator (alternator) is of a
permanent-magnet brushless tubular.
Technical Progress
– The α-prototype is completed
and operational.
– Motoring the linear alternator
• 820 gram moving mass
• 70-93 Hz resonance frequency
• Displacement <2.7 cm
• Engine assembly installed
Coil
– Complete alternator design.

team that can
work effectively
together
– We are collaborating with Dr. Qiu (formerly at Temple
University now at WVU.
– Celebrate
milestone
achievements
– Plan – plan – plan ahead
Next Steps
– Preliminary combustion test on α-prototype
– Extensive operation, data collection and analysis of the α-
prototype and energy audit
– Operate and testing the b-prototype
– Complete design of the b-prototype
– Have the b-prototype ready for testing
– Optimize and fine tune the b-prototype
