Abstract
The invention relates to an engine with a constructional design and material composition for optimum thermal conductivity and vibration damping functions. The invention consists in the cylinder section (11) surrounding the combustion chamber being made of a light metal alloy and in the lower part of the cylinder section being connected to a crankcase section (13) with integral lateral walls (21,22) which enclose the cylinder section (11) with an air gap, and the crankcase section is made of a material with higher density than the cylinder section, preferably cast iron.
