    • The object of the invention is to provide an improved graphic display meter which is prevented from causing inconvenience to the vehicle operator, when a motion blur display mode is switched to a normal display mode.When a motion blur pointer image 10 is switched to a normal pointer image 20a, multiple pointer images 20 including the normal pointer image 20a are displayed adjacent to or in abutment with a leading part of the motion blur pointer image 10 in a direction where the pointer is rotating. The multiple pointer images 20 are consisted of the normal pointer image 20a and a plurality of auxiliary pointer images 20b, which are aligned with one another and are positioned in close proximity to the normal pointer image 20a. The multiple pointer images 20, a plurality set of which have been stored as data in advance, are selected on the basis of a space between the motion blur pointer image 10 prior to the switching of the pointer image and the normal pointer image 20 after the switching of the pointer image.
    • 本发明的目的是提供一种改进的图形显示仪表,当运动模糊显示模式切换到正常的显示模式时,该显示仪被防止对车辆操作者造成不便。 当运动模糊指针图像10被切换到普通指针图像20a时,包括普通指针图像20a的多个指针图像20被显示在与运动模糊指针图像10的前导部分相邻或邻接的位置上 正在旋转。 多指针图像20由正常指针图像20a和多个辅助指针图像20b组成,多个辅助指针图像20b彼此对准并且位于紧邻正常指针图像20a的位置。 基于在指针图像切换前的运动模糊指针图像10和在指针图像切换后的正常指针图像20之间的空间,多个指针图像20被预先存储为数据的多个指针图像20被选择 切换指针图像。

    • An engine air-fuel ratio control system is configured to use a rich air-fuel ratio immediately after starting an engine such that the air-fuel ratio converge rapidly toward a stoichiometric value and then afterwards start an air-fuel ratio feedback control. Upon determining an air-fuel ratio sensor is active, a stabilization fuel quantity increasing factor that is a component of a target air-fuel ratio revising coefficient is decreased at a higher rate than the rate used before the air-fuel ratio sensor was determined to be active. Air-fuel ratio feedback control is started when the air-fuel ratio corresponds to a stoichiometric air-fuel ratio. After starting air-fuel ratio feedback control, an unburned fuel quantity compensating value is set based on the stabilization fuel quantity increasing factor in effect at that point in time and added to the target air-fuel ratio revising coefficient while, simultaneously, the stabilization fuel quantity increasing factor is set to zero.
    • 发动机空燃比控制系统被配置为在启动发动机之后立即使用浓空燃比,使得空燃比迅速地朝向化学计量值收敛,然后开始空燃比反馈控制。 在确定空燃比传感器有效时,作为目标空燃比修正系数的分量的稳定化燃料量增加系数以比空燃比传感器确定前的使用率更高的速度降低 积极点。 当空燃比对应于理论空燃比时,开始空燃比反馈控制。 在开始空燃比反馈控制之后,基于在该时间点上有效的稳定化燃料量增加因子来设定未燃燃料量补偿值,并将其与目标空燃比修正系数相加,同时确定稳定燃料 数量增加因子设置为零。

    • A spark ignition engine (2) has a fuel injector (8) in an intake port (7). An engine rotation speed sensor (9) detects the rotation speed of the engine (2). The controller (1) determines the target fuel injection amount of the fuel injector (8) during startup of the engine (2) by correcting the basic injection amount in response to the trend in the variation in the engine rotation speed. When the rotation speed of the engine (2) decreases, the controller (1) sets the target fuel injection amount to be smaller than when the rotation speed of the engine (2) is increasing at an identical rotation speed. As a result, effects on the air-fuel ratio related to wall flow relative to fluctuations in the rotation speed of the engine (2) are eliminated and the control accuracy of the air-fuel ratio of the engine (2) is improved.
    • 火花点火发动机(2)在进气口(7)中具有燃料喷射器(8)。 发动机转速传感器(9)检测发动机(2)的转速。 控制器(1)通过根据发动机转速变化的趋势校正基本喷射量来确定发动机(2)启动期间的燃料喷射器(8)的目标燃料喷射量。 当发动机(2)的转速降低时,控制器(1)将目标燃料喷射量设定为小于当发动机(2)的转速以相同的转速增加时的喷射量。 结果,消除了与相对于发动机(2)的转速的波动相关的壁流的空燃比的影响,并且提高了发动机(2)的空燃比的控制精度。

    • A fuel property detecting system comprises a control unit coupled to a fuel injector and an air-fuel ratio sensor. The control unit is arranged to sample data of a response wave-form of an exhaust air-fuel ratio in response to an injected fuel quantity at a transient period, to identify a plant model as to fuel in use by controlling a parameter of a previously constructed plant model on the basis of the input and output data so as to decrease a prediction error between the plant model and a norm model, to calculate a cutoff frequency of the identified plant model, and to estimate a fuel property of the fuel in use from the calculated cutoff frequency of the identified plant model and data previous stored in the control unit.
