  • Publication number: 20130091831
    Abstract: An exhaust gas purification device is arranged in an exhaust gas route of a common rail type engine. At least one of an intake air throttle device and an exhaust gas throttle device are arranged in intake and exhaust systems of the engine. In the case that a clogged state of the exhaust gas purification device becomes equal to or more than a prescribed level, an auxiliary renewing mode which raises the temperature of an exhaust gas from the engine by actuating at least one of the intake air throttle device and the exhaust gas throttle device is executed, and in the case that the clogged state of the exhaust gas purification device is not improved even by executing the auxiliary renewing mode, a forced renewing mode which supplies a fuel into the exhaust gas purification device by a post injection is executed.

  • Publication number: 20120324871
    Abstract: In order to relief a sudden change of engine sound during the transition to recovery control of a particulate removing filter or during returning from the recovery control, a system of treating exhaust gas of an engine includes an exhaust-gas particulate removing filter in an exhaust path, closes down the opening of an inlet throttle valve or an exhaust throttle valve to a recovery opening smaller than a normal opening during recovery of the particulate removing filter, and returns the opening from the recovery opening to the normal opening after the recovery of the particulate removing filter. The opening of the inlet throttle valve or the exhaust throttle valve during the closing process from the normal opening to the recovery opening and during the returning process from the recovery opening to the normal opening is changed at a gradually decreasing or gradually increasing rate of change of the opening.

  • Patent number: 8260176
    Abstract: A developer storing container includes a developer storing portion having a developer outlet opening at a substantially longitudinal center portion, and an agitation member rotatable about a rotation axis to thereby agitate and eject the developer via the developer outlet opening. The agitation member includes a mounting portion with a mounting surface along the rotation axis, and an elongated flexible member having first and second ends. The flexible member is mounted to the mounting portion at the first end so that the second end defines a sliding end portion at which the flexible member slides in a sliding direction. Both longitudinal end portions of the sliding end portion of the flexible member slide along the inner surface of the developer storing container, ahead of a substantially longitudinal center portion of the sliding end portion in the sliding direction, and are inclined with respect to a direction perpendicular to the sliding direction.
