A control apparatus is disclosed for optimizing the regeneration of an aftertreatment device located in an exhaust pipe of an internal combustion engine of a vehicle. The control apparatus includes an Electronic Control Unit configured to collect data from a GPS device associated to the vehicle, determine a time period for starting a regeneration of the aftertreatment device on the basis of data collected by the GPS device, and initiate the a regeneration of the aftertreatment device within the time period.

A method is provided to diagnose a failure of an OPCJ valve of an internal combustion engine. The OPCJ valve is located in an auxiliary line connecting an engine lubrication line to at least an oil jet for squirting lubricating oil from the engine lubrication line towards a piston surface. The method provides for monitoring the pressure variation in the engine lubrication line due to a switching signal sent to the OPCJ valve.
