    摘要: In this apparatus, maintaining control (time t1 to t2) which instructs fixing of the open timing VVT of an intake valve is executed in a predetermined low load state. Subsequently, there are executed changing control which instructs changing of the open timing VVT by a predetermined amount (time t2), and maintaining control which again instructs fixing of the open timing VVT of the intake valve (time t2 to t3). An intake-valve control apparatus is determined to be “anomalous” when an change amount Δave (=ave2−ave1) between the average ave1 of a large number of sample values of ΔMFBβ (combustion percentage increase amount within a predetermined crank angle range in an expansion stroke) during the maintaining control before execution of the changing control and the average ave2 of a large number of sample values of ΔMFBβ during the maintaining control after execution of the changing control is less than a predetermined value C.

    摘要: This control apparatus estimates a full combustion correspondence period CP, which is the period from an ignition timing SA to a combustion completion time CAe, and controls a VVT advancement amount (burnt gas quantity, overlap period, intake valve open timing) such that the estimated full combustion correspondence period CP coincides with a constant target full combustion correspondence period CPtgt. The full combustion correspondence period CP substantially maintains a one-to-one relation with the VVT advancement amount at which HC, CO2, etc. start to increase, even when the ignition timing SA changes. Thus, even when the ignition timing changes, the burnt gas quantity (overlap period) can be properly controlled. As a result, without increasing the discharge quantities of HC and CO, the discharge quantity of NOX can be reduced. In addition, pumping loss can be reduced, whereby fuel consumption can be improved.

    摘要: In a control apparatus, when an engine is cranked, “an air-fuel mixture (an air-fuel mixture used for determination of fuel property) including fuel in a first predetermined fuel amount TAUm and air in a first predetermined air amount Mcm”, which generates torque that does not make the engine autonomously operate, is formed in a first cylinder (cylinder used for determination of the fuel property), and the air-fuel mixture is ignited and combusted by a spark at an ignition timing after a compression top dead center. Further, the control apparatus determines “an amount of heat generated per unit mass of the fuel” when the air-fuel mixture is combusted in the first cylinder, and determines a property of the fuel based on the amount of generated heat.
