Abstract

In a multi-cylinder internal-combustion engine, bearing shell and bearing cap of the bearings for the crankshaft are decoupled from the side walls of the cylinder block which form the crankcase. The bearing shells communicate with the cylinder block directly through column elements. The resilience of the column elements relieves the cylinder block of any transverse flexure by crankshaft forces and reduces the generation of noise.
