Abstract
A turbocharger for an engine is disclosed having a compressor and a turbine mounted remotely from one another on opposite sides of a major structural component of the engine. As one example, an engine system comprises a cylinder block and a turbocharger including a compressor and turbine rotatably coupled via a drive shaft, where the compressor and turbine are positioned on opposite sides of the cylinder block relative to a crankshaft axis. Further, the drive shaft traverses the cylinder block and is rotatably supported at each end by a bearing supported by a part of the cylinder block.
Claims20
A turbocharged engine having a crankshaft and a turbocharger, the turbocharger comprising a compressor supplying charge air to at least one intake of the engine, a turbine connected to at least one exhaust of the engine and a drive shaft drivingly connecting the compressor to the turbine, the compressor being located remotely from the turbine on an opposite longitudinal side of a major structural component of the engine wherein the drive shaft is rotatably supported at each end by a respective bearing and at least one of the bearings is carried by the major structural component of the engine.
A method of assembling a turbocharger having a compressor housing, a compressor rotor, a turbine housing, a turbine rotor and a drive shaft to an engine having a crankshaft, wherein the method comprises providing at least two aligned bearings on the engine for supporting the drive shaft, at least one of the bearings being carried by the major structural component of the engine, attaching one of the turbine rotor and the compressor rotor to one end of the drive shaft, engaging the other end of the drive shaft with the at least two bearings such that the drive shaft is positioned at substantially ninety degrees to an axis of rotation of the crankshaft, attaching the other of the turbine rotor and the compressor rotor to the drive shaft and fastening the compressor and turbine housings to opposite longitudinal sides of a major structural component of the engine.
A method as claimed in 10, wherein the method further comprises balancing the compressor rotor, drive shaft and turbine rotor as a sub-assembly before fitting the sub-assembly to the engine.
An engine system, comprising:
- a cylinder block;
- and
- a turbocharger including a compressor and turbine rotatably coupled via a drive shaft, where the compressor and turbine are positioned on opposite sides of the cylinder block relative to a crankshaft axis, where the drive shaft traverses an interior of the cylinder block and is rotatably supported at each end by a bearing, where each bearing is supported by a part of the cylinder block.
