INTERNAL COMBUSTION ENGINE HAVING AN INTAKE DEVICE

摘要

An internal combustion engine has an intake device having an air filter and at least one port. Combustion air is sucked in from the clean side of the air filter to the internal combustion engine via the port. The intake device has air trunking, in which at least a first section and a second section of the port are guided. The air trunking has a longitudinal center axis, wherein combustion air flows in the first section of the port in a first direction of flow running in the direction of the longitudinal center axis. The combustion air flows in the second section of the port in a second direction of flow oriented in an opposite direction to the first direction of flow and in the direction of the longitudinal center axis. As a result, a compact overall size is achieved with port length.
