Abstract

A method for introducing microwave energy into a combustion chamber of an internal combustion engine in which the microwaves reach a combustion chamber through a microwave window, wherein the microwaves are run about a circumference of the combustion chamber and radially coupled into the combustion chamber after passing through the microwave window. Accordingly a device for introducing microwave energy into the combustion chamber of a reciprocating piston internal combustion engine with at least one cylinder with a cylinder head and a combustion chamber in the cylinder includes at least one circumferential annular hollow conductor cavity extending about the combustion chamber and including at least one feed for the microwave and at least one outlet opening for the microwave arranged between the annular hollow conductor cavity and the combustion chamber. An internal combustion engine includes the features of the device.
