Abstract
A control system for controlling the supply of oil to a turbocharger fitted to an internal combustion comprises an oil supply valve () controlled by a controller () and at least one sensor (-) for monitoring a parameter associated with the existence or potential occurrence of a leak in the turbocharger oil supply, or of a condition potentially resulting in such a leak. The controller () is operable to determine the existence or possible occurrence of an oil leak in the turbocharger oil supply in response to a signal received from the sensor (-) and to close the oil supply control valve () in the event of said determination to cut off the oil supply to the turbocharger.
