摘要： A variety of methods and arrangements for detecting failure of the commanded air induction in an internal combustion engine are described. In some embodiments, the intake manifold pressure is monitored. An air induction event generates a fluctuation in the intake manifold pressure, which is recorded. The signal is processed through a diagnostic filter to help determine whether the actual induction matched the commanded induction. In other embodiments, measured crankshaft acceleration is compared with estimated crankshaft acceleration. If the two quantities differ by a threshold amount an induction fault is detected. The two detection methods may also be combined. The describe approaches are particularly well suited for use in engines operating in a skip fire mode with cylinder deactivation and/or a dynamic firing level modulation mode.

摘要： The pressure in the combustion chamber of an electronically controlled spark plug ignition engine may be estimated in real time mode without specific sensors by processing sensed ionization current data to calculate features of the current waveform proven to be correlated to the pressure inside the engine cylinders and correlating them on the basis of a look up table of time invariant correlation coefficients generated through a calibration campaign of tests on a test engine purposely equipped with sensors. A mathematical model of the electrical and physical spark plug ignition system and combustion chamber of the engine is refined during calibration by iteratively testing the interactive performance of correlation coefficients of related terms of a mathematical expression of the model and comparing the expressed pressure value with the real pressure value as measured by a sensor.

摘要： An engine includes a EGR valve to regulate a EGR flow rate. A blow-by gas recirculation passage allows blow-by gas generated in the engine to flow in a surge tank to return to the engine. A PCV valve operates in response to negative pressure to regulate a blow-by gas flow rate in the recirculation passage. During deceleration fuel cutoff of the engine, an ECU holds a throttle valve at a predetermined slight opening degree and controls the EGR valve to be forcibly opened from a valve-closed state to change intake pressure (negative pressure) in the surge tank and determines whether or not the PCV valve is in sticking failure based on changes in intake amount detected by an air flow meter before and after the negative pressure changes.
