Abstract
A turbocharger for an internal combustion engine comprising a housing wherein the housing comprises one or more coolant passages for receiving a coolant to cool the turbocharger and one or more lubricant passages for receiving a lubricant to lubricate the bearings. The lubricant may be the lubricant for both the turbocharger bearings and the internal combustion engine. The coolant passages and lubricant passages in the turbocharger may be arranged in the housing to transfer heat from the lubricant to the coolant such that the transfer of heat between the coolant passages and lubricant passages is sufficient to cool the lubricant to a temperature that is suitable for subsequent use in the internal combustion engine.
