摘要

#CMT# #/CMT# The car (101) has a replaceable range extender (102), and a rotary piston comprising a rotary piston cavity. A lubrication system guides a lubricant, and an area is limited by a side piece opposite to an outer side of a support side part. A complete circumferential groove is formed in a space of a rotary piston within the region of middle of an eccentric shaft for distribution of lubricant and/or collection of the lubricant for supply. A valve is laid out for prevention of an uncontrolled return of the lubricant. #CMT# : #/CMT# An independent claim is also included for a method for lubricating a rotary piston engine in a replaceable rank extender for a motor car. #CMT#USE : #/CMT# Motor car i.e. electric car. #CMT#ADVANTAGE : #/CMT# The complete circumferential groove is formed in the space of the rotary piston within the region of middle of the eccentric shaft for distribution of lubricant and/or collection of the lubricant for supply, so that the replaceable range extender enables the supply of the lubricant within the rotary piston engine to components that can be lubricated. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a motor car. 101 : Motor car 102 : Replaceable range extender.
