摘要： A method for protecting an exhaust aftertreatment system of an internal combustion engine from deterioration by selectively diverting exhaust gases from the engine away from a component of the exhaust aftertreatment system includes assessing a status of an operating condition associated with a physical condition of the component of the internal combustion engine. The status of the operating condition is compared with a threshold value that corresponds with deterioration of the physical condition of the component. A valve upstream of the component is moved to a first position to open a bypass fluid path directing exhaust gases around the component when the status of the operating condition meets the threshold value to reduce deterioration of the component. The valve is move to a second position to close the bypass fluid path thereby directing exhaust gases to the component when the status of the operating condition does not meet the threshold.

摘要： An improved cooling fluid passage configuration provides for uniformity of cooling about the entire periphery of a cylinder liner of an internal combustion engine in addition to improved cooling by increasing the flow in an upper water jacket of a split water jacket design. The cooling fluid passage configuration also provides a reduced pressure drop between a cylinder liner cooling fluid inlet and a cylinder head cooling fluid outlet when compared to conventional designs with a single head feed line, permitting use of a smaller cooling fluid pump and leading to increased efficiency of the engine.

摘要： The disclosure provides a method, system and internal combustion engine system in which a closed-loop system having a controllable variable is monitored to detect the off- nominal behavior of the closed-loop system and raise an alarm or other alerting mechanism when fault is detected. The faults in a closed-loop system show up in such a way that the tracking error signal is impacted and this impact manifests itself as a change in the frequency components. A filter is used to isolate a band of frequency components of the tracking error signal that are more impacted than other by deviation caused by a fault to be detected. The filter can be designed to effectively amplify the section of the error tracking signal that contains the frequency components that have the major impact. In addition, the filter will also have the characteristics to attenuate the impact of other frequency components. An accumulated error signal is generated from the filtered tracking error signal, compared with a predetermined fault threshold characteristic, and a fault indication/warning/alert is provided for the closed- loop system if the accumulated error signal meets the predetermined threshold.
