Abstract

A method for improving combustion in a main combustion chamber of an internal combustion engine and a resulting engine are disclosed. The engine includes a main combustion chamber arranged between a head and a reciprocating piston. A heat retaining element is provided between the head and the main combustion chamber. The heat retaining element is configured to reduce heat transfer from the main combustion chamber into the engine head. A precombustion chamber is provided having a reaction chamber. The reaction chamber is configured to be provided with a secondary charge of air/fuel and a first spark igniter.
