摘要： A method to adjust an oil control valve actuation response time using cylinder valve diagnostic results includes commanding an engine cylinder to deactivate/reactive when conditions are met and then detecting if a deactivation/reactivation response time failure has occurred by analyzing the cylinder diagnostics results. If a predetermined number of failures are detected at the cylinder within a predetermined number of engine cycles then the engine controller operates to adjust the oil control valve response time to improve the response time accuracy.

摘要： An engine control system and method utilizes a processor and a valve controller in communication with the processor. A valve having a solenoid is in communication with the valve controller. The valve controller is configured to receive a combined selection and control signal from the processor, decode a desired electric current profile encoded in the signal, sense a control code encoded in the signal, and operate the solenoid in accordance with the decoded desired electric current profile in response to sensing the control code.

摘要： At every ignition cycle, when a duration change amount ΔT30[i] is equal to or less than a reference value ΔT30ref2, a misfire counter Cmf is kept unchanged. When the duration change amount ΔT30[i] is greater than the reference value ΔT30ref2, on the other hand, the misfire counter Cmf is incremented by value 1. A misfire ratio Rmf is set to provide a smaller value when an amount increasing determination flag F[i] is equal to value 1 than a value when the amount increasing determination flag F[i] is equal to value 0. In the case where an ignition counter Ci reaches or exceeds a reference value Ciref, it is determined whether a conversion catalyst is overheated by comparison between the misfire counter Cmf and an accumulated misfire ratio Rmfsum that is an accumulated value of the misfire ratio Rmf.

摘要： A method is provided to operate a diesel particulate filter of a Diesel engine equipped with a soot-sensor located in an outlet of the diesel particulate filter, the soot-sensor operating according to a succession of soot loading phases mutually separated by a regeneration phase. The method includes, but is not limited to setting a borderline value of the efficiency of the diesel particulate filter, resetting a value of a counter, during a regeneration phase of the soot-sensor, this value representing a soot loading level of the soot-sensor, iteratively increasing the value of this counter, during a next soot loading phase of the soot-sensor, at least until the value reaches a predetermined threshold value of the counter, and detecting an unsuited efficiency of the diesel particulate filter, if a next regeneration phase of the soot-sensor begins when the value of the counter is below the predetermined threshold value of the counter.

摘要： Of a counter apparatus, a first microcomputer and a second microcomputer communicate with each other and receive a crank signal with pulses. The first microcomputer detects a first pulse count number at a detection time point and transmits it to the second microcomputer. The second microcomputer detects a second pulse count number at a determination time point, which is an allowable delay time period later from the detection time point. The allowable delay time period is expected to elapse from the detection time point to when the first pulse count number is received by the second microcomputer. The second pulse count number is compared with a determination value, which is the sum of (i) the first pulse count number and (ii) the largest integer not greater than the quotient of T2/T1, T1 being a pulse period of the crank signal, T2 being the allowable delay time period.

摘要： A method for controlling the operation of a valve of a fuel injector. The method may include selecting an electrical current waveform from a plurality of selectable electrical current waveforms. The selected electrical current waveform is provided to the valve, which may be operated to control a characteristic of an injection event, such as, for example, fuel pressure, injection timing, and/or fuel mass, among others. The method further includes detecting an aberrant combustion event from the combustion of the injected fuel. If an aberrant combustion event is detected, the electrical current waveform associated with the injection event may be disabled. Additionally, upon detection of an aberrant combustion event, a value corresponding to the number of detected aberrant combustion events is incremented, which may be used to determine whether or not to continue to disable the selected waveform.
