Shutdown control of internal combustion engine comprising lost motion component

An engine controller operatively connected to an internal combustion engine comprising a plurality of cylinders and, for each of the plurality of cylinders, a hydraulically controlled lost motion component operatively connected to an engine valve corresponding to the cylinder, the controller comprising:

• at least one processing device;
• and
• memory having stored thereon executable instructions that, when executed by the at least one processing device cause the at least one processing device to:
• determine that shutdown of the internal combustion engine has been requested;
• responsive to the request for shutdown, initiate or continue cylinder deactivation operation for each of at least one cylinder of the plurality of cylinders;
• and
• upon completion of shutdown of the internal combustion engine, discontinuing cylinder deactivation operation for one or more of the at least one cylinder of the plurality of cylinders,
• wherein those executable instructions that cause the at least one processing device to initiate or continue the cylinder deactivation operation for each of the at least one cylinder are further operative to, for an input to the hydraulically controlled lost motion component for each of at least one engine valve corresponding to the cylinder, operate the input to provide the cylinder deactivation operation for a duration at least long enough to complete shutdown of the internal combustion engine.
