Generator of AC with a double chamber linear engine.It is not clear what was the intention and which is the question.
This solution has been already used and there are some such generators (with fuel as diesel engines) working but I do not know any more where.
With so little information and a really bad translation to English this one's a little hard to understand.
My 'gut' (and experience) tells me this is an "Alternative Generator Design" with a picture of a permanent magnet being pushed back and forth within a coil (and what looks like two internal combustion engine cylinders back to back) to generate electricity. As it is in the automotive section perhaps it is an ICE used to create AC to power Ac motors of an electric vehicle.
Totally unworkable design in so many ways (even without an English translation).
The design is not complete in fact there are 2 2-stroke cylinders coupled and moving the PM in the coil. Not represented are the compression chambers for the air before it enters the cylinders.
Such generators named with "free pistons engines" were developed over 80 years ago by a french-italian inventor (De Pescara). After the war the engine used as hot gas generator was even worth a trial at GM for a car turbine supply. DEMAG build big units for same scope but for stationary units. Same principle is used today by a dutch company as prime mover for hydraulics in cars and an american company tries to make it working in the states.
