Abstract
A pump unit may include a pump configured to increase a pressure of diesel fuel and discharge the diesel fuel to a fuel passage in which a filter is disposed, and a controller configured to control an operation of the pump. The controller may be configured to execute freeze avoidance control in which the operation of the pump is controlled using an index that indicates a degree of clogging of the filter caused by the diesel fuel freezing. In the freeze avoidance control, the controller may be configured to apply a higher load to the pump as the degree of clogging of the filter indicated by the index is higher.
