Abstract

The invention relates to a two cycle engine comprising a lean lubrication system, whereby the lubrication oil is only applied in the area of a contact surface between a piston and a cylinder. An oil outlet is provided in or below a running surface pertaining to the cylinder for this purpose. An oil aerosol can be applied alternately, according to the position of the piston, onto the running surface of a shaft pertaining to the piston and onto the running surface of the cylinder via said oil outlet.
