Valve performing detection and modification strategy for internal combustion engine
InactiveUS20080141957A1Internal-combustion engine testingInternal combustion piston enginesExhaust valveExternal combustion engine
A method for operating a multi-cylinder internal combustion engine includes controlling opening of intake or exhaust valves, via a step of generating a control current in a control circuit for an electrical actuator coupled with the valve. The control circuit is then monitored for an induced current that differs from the control current, and a signal outputted that is indicative of valve performance responsive to monitoring the control circuit. Another operating method includes determining engine valve performance and also trimming an engine valve based on one signal which is indicative of valve performance. An internal combustion engine includes an electrical actuator configured to control opening or closing of one of an intake valve and an exhaust valve. An electronic control module is configured via a software fault detection routine to determine a performance condition of an intake or exhaust valve in the engine via monitoring a control circuit for induced currents when an electrical actuator coupled with the intake or exhaust valve is de-energized.

The invention belongs to the technical field of open source software reliability models, and particularly relates to an open source software reliability modeling method for introducing faults based ona debugging process. The method comprises the following steps: (1) proposing a model hypothesis; (2) establishing a differential equation; and (3) establishing an open source software fault detectionreliability model. According to the method, on the basis of fully considering that time delay exists between actual open source software fault detection and fault removal, a corresponding open sourcesoftware reliability model is established by considering the situation that faults are possibly introduced when the faults are removed. Due to the fact that the situation that faults are possibly introduced when the faults of the open source software are removed is considered, the established ground open source software reliability model better conforms to the actual fault detection and fault removal change process, and the assumption of establishing the ground open source software reliability model is more reasonable and credible.
