Abstract

An internal combustion engine includes a compression chamber that is delimited by fixed housing walls and a movable piston mounted therein, and a porous component that fills the combustion chamber, which is separate from the compression chamber. The combustion of fuel and air takes place exclusively within the porous component. The compression chamber is connected to the combustion chamber only via an overflow cross-section designed to allow the transfer of combustion gases created during combustion from the combustion chamber into the compression chamber.
