Claim 6:
7. The method of claim 1 wherein:
the method further comprises determining an incremental engine load request in response to at least one of a throttle command, a gear shift operation, and a request to actuate an aftertreatment system during a time period in which a fuel delivery event is being skipped; and
controlling a supply of fuel from the high pressure fuel pump during the time period in which the fuel delivery is being skipped during the cylinder deactivation mode operation in response to the incremental engine load request by:
causing fuel to be supplied from the high pressure fuel pump to the common rail fuel accumulator if the monitored fuel load is less than or equal to a second load value, and wherein the second load value is greater than the first load value; and
causing fuel from the high pressure fuel pump to be recirculated, dumped, or shunted and not supplied to the common rail fuel accumulator if the monitored fuel load is greater than the second load value.
