  • ROTARY PISTON ENGINE AND METHOD FOR PRODUCING A ROTARY PISTON ENGINE
    Publication number: 20150017044
    Abstract: A rotary piston engine comprises a stationary housing and a piston movably accommodated in the housing. The housing and the piston form at least one chamber with a chamber surface. At least one partial portion of the chamber surface has a thermal barrier coat for reducing a thermal conductivity of the partial portion of the chamber surface. At least one partial portion of the chamber surface has a metallic spray coat. A method for producing such a rotary piston engine can also be achieved.
