Abstract
A method (100) and apparatus (10-1) for carrying out the method of mitigating fuel in oil in an internal combustion engine of a hybrid electric vehicle, the method comprising: detecting one or more of a catalyst temperature and a turbine temperature (110); and when the one or more of the catalyst temperature and the turbine temperature exceeds a first temperature threshold, limiting engine torque below a threshold engine torque required for the operation of an enrichment phase of engine operation (120), wherein the enrichment phase of engine operation provides a lambda value less than 1.

A method of mitigating fuel in oil in an internal combustion engine of a hybrid electric vehicle, the method comprising:
- detecting one or more of a catalyst temperature and a turbine temperature;
- and
- when the one or more of the catalyst temperature and the turbine temperature exceeds a first temperature threshold, limiting engine torque below a threshold engine torque required for the operation of an enrichment phase of engine operation such that a maximum torque that can be applied by the engine is not an amount of driver demanded torque that is higher than the threshold engine torque, wherein the enrichment phase of engine operation provides a lambda value less than 1.
