Abstract
An engine assembly is provided. The engine assembly comprises an oil system comprising: a first oil pump configured to supply oil at a first pressure to one or more first components of the engine assembly; and a second oil pump configured to supply oil at a second pressure to one or more second components of the engine assembly, the second pressure being higher than the first pressure; wherein the second oil pump is provided adjacent to a valve train of the engine assembly.
Claims18
An internal combustion engine assembly comprising an oil system, the oil system comprising:
- a first oil pump configured to supply oil at a first pressure and a first flow rate to a low pressure first feed of a turbocharger and one or more first components of the engine assembly;
- and
- a second oil pump configured to supply oil at a second pressure and a lower second flow rate to a higher pressure second feed of the turbocharger and one or more second components of the engine assembly, the second pressure being higher than the first pressure;
- wherein the second oil pump is provided adjacent to a valve train of the engine assembly and wherein the first oil pump is provided adjacent to a crank shaft of the engine assembly, and wherein the first oil pump is a variable pressure pump and the second oil pump is a fixed pressure pump.
A motor vehicle comprising an engine assembly, the engine assembly comprising:
- an oil system, the oil system comprising:
- a first oil pump configured to supply oil at a first pressure and a first flow rate to a low pressure first feed of a turbocharger of the engine assembly;
- and
- a second oil pump configured to supply oil at a second pressure and a lower second flow rate to a higher pressure second feed of the turbocharger of the engine assembly, the second pressure being higher than the first pressure;
- wherein the second oil pump is provided adjacent to a valve train of the engine assembly and wherein the first oil pump is provided adjacent to a crank shaft of the engine assembly, and wherein the first oil pump is a variable pressure pump and the second oil pump is a fixed pressure pump.
