摘要: In engine idle, a throttle valve is set to an intermediate position between the closed position and the open position, which provides a substantial opening for air flow. When an accelerator is initiated, the sufficient air flow amount and speed are already attained in the engine, the engine rotation quickly increases in response to the accelerator movement. During the period before the accelerator arrives at a pick-up position, an electric control unit controls ignition timing in response to the accelerator movement. The amount of fuel injected to the engine is also controlled depending on the accelerator movement. Also during this period, one or more cylinders are set to be inactive by not supplying the fuel thereto. Thus, the engine rotation speed is controlled to be low at idle. In engine deceleration, when the engine is in the range where a backfire tends to occur, the rate of change in the ignition delay and the amount of fuel injection are adjusted depending on the engine rotation speed, the ignition delay and the other physical parameters. In the range where backfire is likely to happen, the rate of change in the ignition delay timing is controlled to be smaller and the amount of fuel injection is controlled to be larger, which will suppress the backfire in deceleration.
摘要翻译: 在发动机怠速时,节气门被设定在关闭位置和打开位置之间的中间位置,这为空气流动提供了实质的开口。 当启动加速器时,在发动机中已经达到足够的空气流量和速度,发动机转速响应于加速器运动而迅速增加。 在加速器到达拾取位置之前的期间,电气控制单元响应于加速器运动来控制点火正时。 喷射到发动机的燃料量也根据加速器运动来控制。 同样在此期间,通过不向其供应燃料而将一个或多个气缸设定为无效。 因此,空转时将发动机转速控制为低。 在发动机减速时,当发动机处于发生逆火的范围内时,根据发动机转速,点火延迟等物理参数来调整点火延迟的变化率和燃料喷射量。 在可能发生回火的范围内,点火延迟定时的变化率被控制得更小,并且燃料喷射量被控制得更大,这将抑制减速的反作用力。

摘要: The automatic analyzer stores: a predetermined period from the opening of a reagent vessel to the deterioration of the reagent; a reagent production lot number, reagent vessel unsealing time, and reagent expiration date as reagent information kept on a reagent-set-by-set basis; and relevant calibration curve factor information. The automatic analyzer judges whether a calibration curve factor for a reagent set is applicable or not to another reagent set of the analyzer with the same production number based on the predetermined period from the reagent vessel unsealing time and on the reagent expiration date.
