  • System for reducing compressor oil consumption
    Patent number: 9261106
    Abstract: An air induction system for a power source including a first compressor and a second compressor is disclosed. The air induction system includes an air feed passageway that directs compressed air from the second compressor to an area between a compressor wheel and a center housing in the first compressor to reduce oil consumption in the first compressor.
    Type: Grant
    Filed: December 15, 2010
    Date of Patent: February 16, 2016
    Assignee: Perkins Engines Company Limited
    Inventors: Tom W. Carlill, Ian Pink
  • Regeneration assist calibration
    Patent number: 8776501
    Abstract: A power system comprising an engine that produces exhaust, a fuel system that injects a fuel into the engine, an aftertreatment system that treats the exhaust, and is controller. The aftertreatment system includes an oxidation catalyst that converts NO from the engine into NO2, a particulate filter that traps soot from the engine, and a sensor that provides an indication of the amount of soot in the particulate filter. The controller increases an engine fuel injection pressure when the amount of soot in the particulate filter is above a threshold.
