摘要

According to a first aspect the present invention relates to an engine arrangement (10) comprising an engine (12), a charge air cooler (14) connected to an engine inlet side (16) of the engine (12), an air bypass (20) for bypassing the charge air cooler (14), and comprising an EGR system (22) connected between an engine outlet side (18) and an engine inlet side (16) of the engine (12) via one or more EGR lines (24). The air bypass (20) enters the EGR system (22) at an air-bypass port (26) of an EGR line (24) for mixing air (34) with exhaust gas (32) at the engine outlet side (18) of the EGR system (22) and/or upstream of an EGR cooler (38). According to a second aspect the present invention relates to an engine arrangement, preferably as stated above, comprising an engine (12), a charge air cooler (14) connected via an air line (30) to an engine inlet side (16) of the engine (12), an air bypass (20) for bypassing the charge air cooler (14), and comprising an EGR system (22) connected between an engine outlet side (18) and an engine inlet side (16) of the engine (12) via one or more EGR lines (24). A control device (40) is provided for controlling an engine inlet temperature (T_in) of an air/exhaust gas mixture (36) by controlling a ratio of cooled/uncooled air (34) and/or cooled/uncooled exhaust gas (32) in the air/exhaust gas mixture (36).
