The present invention refers to a piston for an internal combustion engine, particularly a V-engine. The piston comprises an oil drainage groove provided in the outer circumferential surface of the piston between a ring belt and a piston skirt of the piston, the piston skirt being provided with two recessed pin boss portions on opposed sides of the piston, wherein the piston skirt is further provided with at least one oil drainage duct arranged between the two recessed pin boss portions at an outer surface of the piston skirt and configured to fluid-communicatively connect the oil drainage groove with the recessed pin boss portions.

Piston for an internal combustion engine

The present invention relates to a charge air cooling unit comprising a first charge air cooler having a first end face provided with a first cooling fluid inlet and a first cooling fluid outlet and a second charge air cooler having a second end face provided with a second cooling fluid inlet and a second cooling fluid outlet. Specifically, the second charge air cooler is arranged adjacent to the first charge air cooler such that the first end face and the second end face are oriented in the same direction. Further, the charge air cooling unit comprises a manifold unit connected to the first end face and the second end face for guiding a cooling fluid through the first charge air cooler and the second charge air cooler.

Charge air cooling unit for a two-staged turbocharger

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

Two-stage turbocharged internal combustion engine

A cylinder block of an engine is provided. The cylinder block includes a cast body defining one or more cylindrical bores. The cylinder block also includes a crankshaft bearing wall formed within the cast body. The crankshaft bearing wall is configured to be removably coupled with a bearing cap to define an opening for rotatably supporting a crankshaft of the engine. The cylinder block further includes a chamfered shoulder portion casted on the crankshaft bearing wall.

Cylinder block of internal combustion engine

An engine system includes an engine with a crankshaft. The crankshaft is rotatable about a crankshaft axis that is defined in a first plane. A turbocharger includes a turbine and a compressor. The turbine is configured to be driven by an exhaust gas flow from the engine and drive the compressor about a common turbocharger axis. An included angle defined between a projection of the common turbocharger axis onto the first plane and the crankshaft axis is an acute angle.
