Internal combustion engine

The invention relates to an internal combustion engine. An internal combustion engine (1) for combusting an air-fuel mixture (2) containing air (3) and fuel (4), comprising at least one temperature regulating device (5) for cooling or heating the air (3), the fuel (4) and/or the air-fuel mixture (2), and a control unit (6) configured to determine a methane value (7) and/or a hydrogen content (8) of the fuel (4) and/or the air-fuel mixture (2), wherein the control unit (6) is configured to control the temperature of the air (3), the fuel (4) and/or the air-fuel mixture (2) on the basis of the determined methane value (7) and/or the hydrogen content (8) by controlling the at least one temperature regulating device (5). 本发明涉及内燃机。一种用于燃烧含有空气(3)和燃料(4)的空气-燃料混合物(2)的内燃机(1)，包括：至少一个用于冷却或加热空气(3)、燃料(4)和/或空气-燃料混合物(2)的温度调节装置(5)，以及被配置为确定燃料(4)和/或空气-燃料混合物(2)的甲烷值(7)和/或氢含量(8)的控制单元(6)，其中控制单元(6)被配置为通过控制至少一个温度调节装置(5)基于所确定的甲烷值(7)和/或氢含量(8)来控制空气(3)、燃料(4)和/或空气-燃料混合物(2)的温度。
