摘要： PROBLEM TO BE SOLVED: To properly control ignition timing by suppressing erroneous exclusion of vibration with comparatively small strength, and accurately determining an occurrence frequency of knocking, when controlling the ignition timing in response to the occurrence frequency of knocking. SOLUTION: In an engine ECU, a program is executed including a step S202 of calculating a knocking determination level V(KD) by using all strength values LOG(V) below a median VMED of strength values LOG(V) calculated from detected strength V based upon a signal transmitted from a knocking sensor. A rate of strength values LOG(V) larger than the knocking determination level V(KD) is counted as a knocking ratio KC, and a determination value V(KX) is reduced and increased in response to the knocking ratio KC. Existence or nonexistence of knocking is determined per each ignition by using the determination value V(KX), and the ignition timing is retarded and advanced. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ignition timing control device capable of accurately acquiring a learning value for an ignition timing control in each of an EGR (exhaust gas recirculation) operation and a VVT (variable valve timing) operation in an internal combustion engine having both of EGR and VVT modes.SOLUTION: The ignition timing control device accurately controls the ignition timing responding to variations of knocking limits by an operation of the EGR mechanism or the VVT mechanism by separately learning a multipoint learning value for EGR and a multipoint learning value of VVT. When the EGR is interrupted in the last tripping time, the EGR is forcibly operated in this time of tripping to give a chance of learning a multipoint learning value for EGR, and thereby, the multipoint learning value for the EGR in this time of tripping is prevented from being left in a delay angle side opposing to an actual state. When the EGR is not interrupted in the last tripping time, EGR is forcibly stopped (VVT is activated) in this time of tripping to give a chance for learning a multipoint value for VVT, and thereby, the multipoint learning value for VVT in this time of tripping is prevented from being left in a delay angle side opposing to an actual state.

摘要： PROBLEM TO BE SOLVED: To solve the problem that when so-called external EGR control is effected, specific fuel consumption is sometimes decreased by retarding the ignition-timing.
SOLUTION: An internal combustion engine is equipped with an exhaust-gas recirculation system for recirculating exhaust-gas downstream of a throttle valve in the intake system, and a variable valve-timing mechanism for controlling opening/closing timing for at least either one of the intake valve and the exhaust valve. By the exhaust-gas recirculation control, according to the state of operation of the internal combustion engine, a changeover is executed between an exhaust-gas recirculation by the exhaust-gas recirculation system and a valve-timing control by the variable valve-timing mechanism. A retard quantity of ignition timing in execution of the exhaust-gas recirculation by the exhaust-gas recirculation system is learned. If the learned retard quantity is higher than the amount of determination of recirculation implementation to be set on the basis of the specific fuel consumption, exhaust-gas recirculation by the exhaust-gas recirculation system is suspended, and the valve timing control is performed by the variable-valve timing mechanism wherein at the ignition timing with the learned retard quantity, the specific fuel consumption is at most the amount of determination of recirculation implementation.
