A paper at the American Chemical Society: Simulation of a Two-Stroke Free-Piston Engine for Electrical Power Generation by Qingfeng Li, Jin Xiao, and Zhen Huang [the quote below about free-piston ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating ...

The free piston engine, a design with opposed pistons working against compressed air springs and combining both compression and firing strokes in a single axis, doesn’t turn anything in itself ...

Prototype free piston engines are already 50 to 60 percent more efficient than any engine currently in production – and there is the potential for much more. How does it work?

The free-piston linear generator’s versatility also allows the device to adapt to operate at optimal efficiency based on the vehicle’s speed and driving characteristics to reduce emissions.

Free-piston engines have great potential for use as generators for range-extended electric cars or even driving a full series-hybrid in place of a more conventional crankshaft-based engine.

Their study of the FPLA, which could provide a low-emission, fuel efficient engine for future hybrid electric vehicles, is scheduled for the Sept. 17 issue of ACS' Energy & Fuels, a bi-monthly ...

Team 01: Free-Piston Linear Generator Abstract We developed a high-efficiency linear generator powered by hydrogen, which has less friction than rotating engines by turning linear motion directly into ...

Stirling engines are really cool machines, invented by Reverend Dr. Robert Stirling in 1816 to rival the steam engine, they are one of the most efficient engines ever conceived. Building one is a … ...

Toyota's latest breakthrough in internal combustion engine (ICE) technology, the W-Piston free-piston engine, marks a pivotal moment in automotive innovation. With an unprecedented 50% efficiency ...
