Internal combustion engine e.g. rotary piston engine used for driving motor vehicle, has pistons that are adapted to define variable volumes to perform various strokes of thermodynamic cycle in circulation chambers within housing

摘要

The engine (100) has a housing (102) that includes an outer housing section (110) and an inner housing section (124) that are rotatably arranged relative to each other about an axis of rotation (136). Multiple pistons (104) are respectively arranged in the circulation chambers (106,108) with rotation axes (142,144) within the housing. The pistons are adapted to define variable volumes to perform an intake stroke and a compression stroke and a power stroke and an ejection stroke of a thermodynamic cycle in the circulation chambers within the housing.
