摘要： A control system for a vehicle in which an internal combustion engine whose output torque is controlled based on a required output power is coupled to a continuously variable transmission whose input rotation speed is controlled based on the required output power. A controller of the system determines a final target operating point of the engine which is defined by the output torque and the input rotation speed, on the basis of the required output power, and sets a transient operating point to one of possible operating points that can be achieved within a predetermined period of time such that the operating point of the engine approaches the final target operating point. The controller then controls the output torque and the input rotation speed of the continuously variable transmission so as to operate the engine at the set transient operating point.

摘要： With an increase in torque demand, the internal combustion engine of the invention successively changes over a combination of a compression ratio, an air-fuel ratio, and a boost status of an air-fuel mixture from (1) settings of a high compression ratio, a lean air-fuel ratio, and a non-boosting state, (2) settings of the high compression ratio, the lean air-fuel ratio, and a boosting state, (3) settings of a low compression ratio, the lean air-fuel ratio, and the boosting state, to (4) settings of the low compression ratio, a stoichiometric air-fuel ratio, and the boosting state. The changeover strategy desirably widens a driving area of the internal combustion engine at the high compression ratio of a high thermal efficiency or at the lean air-fuel ratio. Under the condition of a large torque demand, the internal combustion engine is driven with boosting the stoichiometric air-fuel mixture at the low compression ratio to output a sufficiently large torque. The arrangement of the invention adequately changes over the compression ratio, the air-fuel ratio, and the boost status of the internal combustion engine, thus simultaneously enhancing the thermal efficiency and the maximum output of the internal combustion engine.

摘要： An internal combustion engine is provided with a VVT mechanism capable of adjusting overlap period in which both intake and exhaust valves are open. The internal combustion engine is also provided with a recirculation mechanism that recirculates exhaust gas to the intake side. An EGR map from which internal EGR amount based on the VVT mechanism and external EGR amount based on the recirculation mechanism are derived in accordance with engine speed and engine torque is prepared. The EGR map is realized as a four-dimensional map that also takes engine intake air temperature and engine coolant temperature into account. By performing EGR control in consideration of these parameters, the occurrence of knocking during EGR control can be suppressed, and an improvement in fuel consumption and the like can be achieved with certainty.

摘要： A knock detection device for an internal combustion engine make provisions to prevent erroneous decisions from being made due to a steplike signal change at the time of mask removal or to an overlap between an LC resonance generation period and a knock occurrence period in high engine rpm conditions. A low-frequency component is removed from an ion current signal by an HPF, and the resulting flat signal is supplied to a mask circuit, thereby reducing the amount of discontinuity occurring at the time of mask removal and suppressing noise in an output signal of a BPF to a level that does not affect knock detection. Further, by setting the gate period in a peak-hold circuit slightly delayed with respect to the mask removal timing, noise associated with the mask removal is completely eliminated. As mask signals used to specify the mask period, in addition to a mask signal for removing the mask when a predetermined crankshaft angle is reached, a second signal is provided for removing the mask when a prescribed time required for LC resonance noise to settle down has elapsed from the end of spark discharge, and the mask is removed only when both of the mask signals are deactivated.

摘要： A knock detection device for an internal combustion engine prevents erroneous knock detection decisions from being made due to an LC resonant current in an ion current path. An LC resonance frequency, which is determined based on an inductance of ignition coil secondary and a stray capacitance formed in the ion current path, is set so as to be displaced from a knock frequency so that the knock frequency component alone can be detected accurately from the ion current output. Preferably, the inductance of the ignition coil secondary is set to a large value, thereby setting the LC resonance frequency lower than the knock frequency and thus improving ignitability as well as knock detectability. Also preferably, the LC resonance frequency is set to a value lower than a lower cut-off frequency of a knock signal extraction band-pass filter provided in a processing circuit. This ensures more reliable elimination of the noise causing LC resonance frequency component.

摘要： A device for detecting knocking in an internal combustion engine which, when spike noise or noise due to disturbance in the flame in low-load running are generated, does not erroneously detect it as knocking. Knocking frequency components passing through a band-pass filter 32 and frequency components lower than the knocking frequency and passing through a low-load noise band-pass filter 321 are picked from the ionic current detected by an ionic current detecting unit 17. When the level of the low-frequency components is larger than a predetermined value, it is regarded that the noise is generated due to unstable combustion during the low-load operation or the spike noise is generated due to corona discharge of a spark plug 16, and the determination of the occurrence of knocking is prevented. This constitution makes it possible to prevent erroneous detection of knocking.
