摘要： A fuel injection control apparatus of a four cycle engine having six cylinders comprises: a crank angle detection device for detecting the crank angle of the four cycle engine; a first computation device for computing the quantity of fuel, which is injected in a predetermined stroke of a four stroke cycle, at a first computation timing; a second computation device for computing the quantity of fuel, which is injected one stroke before the predetermined stroke, at a second computation timing 240 degrees ahead of the crank angle of the first computation timing; and a third computation device for computing the quantity of fuel, which is injected two strokes before the predetermined stroke, at a third computation timing 120 degrees ahead of the crank angle of the second computation timing. The fuel injection control apparatus is adapted to decrease interruptions by computations for fuel injection control in the six cylinder engine, and reduce control load.

摘要： Techniques and controllers are described for dynamically determining when to request firing decisions for individual firing opportunities while operating an internal combustion engine in a skip fire mode. In one aspect, a skip fire controller is arranged to periodically determine the timing by which a next cylinder firing decision request must be made in order to assure that a corresponding firing decision can be implemented as desired, and whether there is sufficient time to wait until at least the next periodic timing determination is made to request the next cylinder firing decision. When there is not sufficient time to wait, a firing decision request is made and the corresponding working cycle is either skipped or fired based on the received firing decision. When there is sufficient time to wait, the firing decision request is delayed until at least the next periodic timing determination is made.

摘要： A control apparatus for an engine includes a control unit. The engine includes a sensor. The control unit determines whether or not an abnormality has occurred in a calculation function of the control unit on the basis of a comparison result between the control required injection amount and the monitoring required injection amount. The control unit determines whether or not an abnormality has occurred in the calculation function of the control unit without using the comparison result when the comparison result is calculated during a predetermined period. The predetermined period is a period of a delay that occurs between updating of one of respective values of the control rotation speed and the monitoring rotation speed and updating of the other value due to a difference between the first timing and the second timing.

摘要： The invention, while reducing noise, suppresses a load increase in a processor and a delay in drive control. An engine control unit includes a processor, a driving circuit including a switching element to drive a load such as a fuel injector and an ignition device, and a communication circuit that transmits control signals from the processor to the driving circuit via serial communication. The control signals each include a command frame for controlling the driving circuit and a data frame for driving the load. If a predetermined bits in each of the data frames received from the processor at predetermined time intervals are determined to be the same twice in succession, the engine control unit changes a state of a driving signal ‘Drive’ for driving the load and thereby changes an operating state of the switching element.

摘要： An engine control apparatus includes a target air volume calculator which calculates a target air volume required by an engine, and an actual air volume calculator which calculates an actual air volume inhaled into a cylinder of the engine. The apparatus further includes an estimator which calculates the estimated value of subsequent actual air volume on the basis of a time lag from a time when the target air volume is calculated to a time when the actual air volume reaches the target air volume. The apparatus can accurately estimate an intake air volume inhaled into the cylinder to improve the controllability of the engine.

摘要： An ignition timing control apparatus for an internal combustion engine, when determining that recalculations are possible from the time when final ignition timing is calculated normally to final ignition timing, recalculates the correction amount of the ignition timing by feedback control and the final ignition timing. Accordingly, engine speed at a time closer to actual ignition timing is reflected on the final ignition timing. This configuration prevents overshoot from occurring even when a feedback gain is made greater and thus allows highly-responsive feedback control of the ignition timing thereby suppressing the change in rotation of the engine effectively. When the recalculations are not performed, the final ignition timing based on the correction amount, as normally calculated, is used. Thus, the final ignition timing is maintained at certain accuracy and abnormal ignition such as accidental fire is prevented.

摘要： In an arrangement, wherein a post-catalytic converter lambda probe is arranged downstream of a catalytic converter having an oxygen store, and wherein both the oxygen store and the post-catalytic converter lambda probe can be subject to aging, a time delay in the reaction of the post-catalytic converter lambda probe with an aged oxygen store to the air-fuel ratio is measured when the associated internal combustion engine operates in an overrun mode. This time delay can be used to determine the oxygen storage capacity. If the oxygen store has not yet aged, a coarse estimate of the time delay is sufficient. The coarsely determined time delay is hereby used to define a coarse limit value in conjunction with a time integral or time duration.
