摘要： A controller including a self-tuning circuit for controlling a pressure system to output an input pressure corresponding to an input pressure value using an adaptive fuzzy control system and updating dosing command values of a dosing command table for controlling a dosing unit of an aftertreatment system. The self-tuning circuit is configured to determine an input pressure value and generate a pressure control signal using the adaptive fuzzy control system based on the input pressure value, a detected input pressure, and an error amount. The self-tuning circuit is further configured to regulate the input pressure of reductant to the dosing unit from a reductant tank using a pressure control signal for a pressure control device. The self-tuning circuit is further configured to update a dosing command value of a dosing command table of the controller in conjunction with regulating the input pressure of reductant.

摘要： The control system of an internal combustion engine performs normal operation control including lean control for making the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst a lean air-fuel ratio, and rich control for making the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst a rich air-fuel ratio. The normal operation control includes judgment reference decreasing control decreasing the judgment reference storage amount in the lean control when during the time period of performing the lean control, the air-fuel ratio of the exhaust gas flowing out from the exhaust purification catalyst becomes the lean judged air-fuel ratio or more. The control system judges that the exhaust purification catalyst is abnormal when the judgment reference storage amount becomes less than a deterioration judgment value.

摘要： A method for checking the leak-tightness of hydraulic components in an exhaust gas aftertreament unit of an internal combustion engine is disclosed. The exhaust gas aftertreament unit uses an electric motor to pump a liquid reductant from a reductant reservoir to a reductant injector that is kept closed. The reductant pump is switched on for a first predetermined period, and the electric current consumed by the electric motor is detected during this period. After a predetermined standstill time has passed, the reductant pump is switched on again for a second period identical to the first period, and the electric current consumed by the electric motor is again detected during this period. The electric currents detected during the two time periods are compared with each other, and the leak-tightness of the hydraulic components downstream of the reductant pump is evaluated based on the result of the comparison.

摘要： A bi-directional tractor exhaust system with ground speed detection includes a downwardly directed exhaust pipe, an upwardly directed exhaust pipe, and an intermediate exhaust pipe connected to the outlet of a diesel particulate filter. An exhaust pipe valve may be opened or closed by an actuator to direct exhaust through the downwardly directed exhaust pipe during regeneration of the diesel particulate filter if a signal from a ground speed sensor indicates ground speed above a first speed, or through the upwardly directed exhaust pipe if the ground speed is below a second speed.

摘要： A purpose of the present invention is to prevent a PM-caused short circuit between a heating element and a case in an electrically heated catalyst. The electrically heated catalyst is provided in an exhaust gas passage of an internal combustion engine the air-fuel ratio of which is controlled at a ratio near a theoretical air-fuel ratio at an operation time. The electrically heated catalyst includes a heating element that generates heat through electric conduction, a case that stores the heating element therein, and an insulating member sandwiched between the heating element and the case. According to the present invention, the heating element is electrically conducted after the operation of the internal combustion engine is stopped.
