Abstract
The invention relates to an rotary piston internal combustion engine (1) comprising at least one rotary piston (4) rotating in a chamber (3) of a housing (2), the chamber (3) being formed by a trochoidal running surface (5) in a central housing part (2a) and interspaced lateral running surfaces (6, 7) arranged normally to an eccentric shaft. Directly or indirectly lateral housing parts (2b, 2c) are arranged in a connecting manner either side of the central housing part (2a) in the direction of the axis (10a) of the eccentric shaft (10). Coolant of a cooling circuit (50a) of a cooling system (50) flows through at least one cooling channel arrangement (52, 53, 54) in the lateral first housing part (2b), the central housing part (2a), and the lateral second housing part (2c) of the piston internal combustion engine (1). The aim of the invention is to achieve an optimum heat dissipation as easily as possible. To this end, the coolant flows through a first piston-side cooling channel arrangement (52) of the lateral first housing part (2b), a central cooling channel arrangement (53) of the central housing part (2a), and a second piston-side cooling channel arrangement (54) of the lateral second housing part (2c) in the coolant circuit (50a) of the cooling system (50) in said order.
