    • An object of this invention is to appropriately control valve timings based on a fuel property and an engine temperature to improve exhaust emissions. An engine is equipped with a function that drives variable valve mechanisms to execute intake valve retarded-opening control and exhaust valve early-closing control. An ECU variably sets a low-temperature determination value based on an alcohol concentration in a fuel. If a water temperature of the engine is equal to or less than the low-temperature determination value, the ECU prohibits the intake valve retarded-opening control and permits the exhaust valve early-closing control. Consequently, during cold operation it is possible to avoid a deterioration in combustion properties (deterioration in in-cylinder turbulence) caused by intake valve control and thereby suppress a deterioration in exhaust emissions. Further, because exhaust valve control is permitted, for example, a negative overlap period that satisfies a control request can be secured by advancing the closing timing of the exhaust valve. Accordingly, exhaust emissions and catalyst warm-up performance can be improved.
    • 本发明的一个目的是根据燃料特性和发动机温度适当地控制阀门定时,以改善废气排放。 发动机具有驱动可变阀机构以执行进气门延迟开启控制和排气门早闭控制的功能。 ECU基于燃料中的酒精浓度可变地设定低温判定值。 如果发动机的水温等于或低于低温判定值,则ECU禁止进气阀延迟开启控制,并允许排气门的早闭控制。 因此,在冷运转时,可以避免由进气门控制引起的燃烧特性(缸内紊流的劣化)的恶化,从而抑制废气排放的劣化。 此外,由于允许排气门控制,例如,可以通过推进排气门的关闭正时来确保满足控制请求的负重叠时段。 因此,可以提高废气排放和催化剂预热性能。

    • A DA converter includes an IV conversion amplifier with output voltage having good linearity, to thus improve total harmonic distortion (THD) characteristics. In the DA converter, a first current path in which current flows due to differential switches being in the ON state in a differential switch section, and a second current path in which current flows due to differential switches being in the OFF state in the differential switch section are connected to the output side of the IV conversion amplifier. A first current flows in the first current path and a second current flows in the second current path. A current equal to the first current plus the second current that is of fixed current amount is drawn by an amplifier stage of the IV conversion amplifier.
