Abstract

An internal combustion engine includes an intake manifold, at least one intercooler, at least one cylinder head with a plurality of piston-cylinder-units, at least one ammonia source, and a controller. Each piston-cylinder-unit includes at least a main combustion chamber, at least one intake valve, and an ignition device. The at least one ammonia source is configured to provide ammonia to each piston-cylinder unit as part of a combustion charge. The controller is configured to control the intercooler to provide a gaseous medium with a temperature of at least 60° C. to the intake manifold, and control a lambda of the combustion charge inside each main combustion chamber to be between 0.9 and 1.2.
