Abstract
Methods and systems are provided for temperature control of a high pressure pump (HPP) of a direct injection system. When direct injection is disabled, the HPP and the associated direct injectors are intermittently operated when the HPP temperature rises above a modeled threshold temperature. The HPP and injectors are operated until the HPP temperature falls below the modeled threshold temperature.
