Abstract
A reciprocating combustion engine includes at least one cylinder, in which a reciprocating piston is arranged back and forth movable. The reciprocating combustion engine includes a pin structure arranged on the combustion chamber side in the area of the cylinder head or the piston bottom. Due to the pin structure, local peak temperatures can be avoided during the combustion process, so that NOx emissions can be avoided or at least greatly reduced. A motor vehicle, for example a commercial vehicle, includes a reciprocating combustion engine.
