摘要： An engine system (100) includes an engine (102) with a crankshaft (114). The crankshaft (114) is rotatable about a crankshaft axis (118) that is defined in a first plane (122). A turbocharger (104) includes a turbine (130) and a compressor (132).

摘要： A two-stage turbocharged internal combustion engine comprises a low-pressure stage turbocharger (26) mounted at a first end side (18) of an engine block (10) and a high-pressure stage turbocharger (28) mounted at the same first end side (18) of the engine block (10). The respective turbochargers (26, 28) are mounted via a mounting structure (50), which also accommodates the charge air coolers (30, 32) associated with the turbochargers (26, 28). In order to obtain a compact arrangement and reduce a length of pipe connections between the different components, the different charge air coolers (30, 32) are mounted to mounting structure (50) such that they overlap in a plan view of the internal combustion engine (1). Further, flow directions of charge air in the different charge air coolers (30, 32) are opposite to each other.
