Abstract
An engine arrangement includes an engine, a charge air cooler connected to an engine inlet side of the engine, an air bypass for bypassing the charge air cooler, and including an EGR system connected between engine outlet side and an engine inlet side of the engine via one or more EGR lines. The air bypass enters the EGR system at an air-bypass port of an EGR line for mixing air with exhaust gas at the engine outlet side of the EGR system and/or upstream of an EGR cooler. An engine arrangement can also comprise an engine, a charge air cooler connected via an air line to an engine inlet side of the engine, an air bypass for bypassing the charge air cooler, and including an EGR system connected between an engine outlet side and an engine inlet side of the engine via one or more EGR lines. A control device is provided for controlling an engine inlet temperature of an air/exhaust gas mixture by controlling a ratio of cooled/uncooled air and/or cooled/uncooled exhaust gas in the air/exhaust gas mixture.
