Abstract
The invention relates to an internal combustion engine for a portable handheld work apparatus such as a motor-driven chain saw or the like. The internal combustion engine includes a cylinder defining a combustion chamber and having an inlet passage for conducting a fuel mixture into the combustion chamber. The cylinder has an annular flange formed thereon and is disposed in surrounding relationship to the inlet passage. An intake pipe defines a longitudinal axis and has an end section. The end section and the annular flange are axially inserted one into the other in overlapping relationship to each other. The annular flange and the end section conjointly define an annular space therebetween radially of the longitudinal axis and a seal is clamped between the annular flange and the end section in the annular space.
