  • Patent number: 9657673
    Abstract: The objective of the present invention is to provide an exhaust purification system that is capable of purifying exhaust gas during both lean and stoichiometric driving. The exhaust purification system is equipped with: a feedback-use identifier, which identifies parameter values such that the error between the output value from a LAF sensor and the estimated value for the LAF sensor output as obtained from a model equation is minimized; and a stoichiometric driving mode controller. The controller performs feedback control and thereby determines the fuel injection amount such that in the stoichiometric driving mode the equivalence ratio value as calculated from the parameters reaches a target value which is set such that a three-way purification reaction occurs in an under-engine catalyst. The identifier identifies the model parameters before feedback control is initiated by the controller.

    Abstract: In accordance with an embodiment, a money depositing and dispensing apparatus comprises a conveyance section, a reception module, a conveyance control module and a notification module. The conveyance section at least conveys either deposited money or dispensed money. The reception module receives a generation notification used to generate an error which relates to the conveyance section and is to be experienced by an operator. In a case in which the reception module receives the generation notification, the conveyance control module prohibits the conveyance of money by the conveyance section. The notification module notifies that the error, received by the reception module, which relates to the conveyance section, is generated.
