A rotary piston internal combustion engine of trochoidal type of construction with dual-arc or curved mantle runway or inner surface and at least one triangular piston having corners thereof in continuous sliding engagement with the inner runway or surface, such piston being journalled by roller bearings and regulated or controlled by a synchronization gear transmission. An oil-collector groove, channel or trough is provided on the shaft on a side remote from the or synchronization gear transmission. Bores in the eccentric lead from the oil-collector groove, channel or trough to the bearing of the piston and the smallest or most nominal oil quantities or volume for lubrication of such bearings, for lubrication of the synchronization gear transmission as well as the sealing parts of the piston, are provided extending in the eccentric.
