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 ...

A new kind of internal-combustion range extender for electric vehicles skips crankshafts and camshafts entirely, with packaging that could more easily coexist with battery packs. The UK firm Libertine ...

A novel but not new kind of engine is figuring more and more often in engineering literature and bull sessions. Last week the Cleveland Diesel Engine Division of General Motors Corp. gave details ...

We developed a high-efficiency linear generator powered by hydrogen, which has less friction than rotating engines by turning linear motion directly into electricity. They are applicable as a range ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...
