    • A combustion variation value is detected, and a function that uses the detected combustion variation value is added to CVAR(i−1) to obtain CVAR(i); and using the resulting value, an exhaust gas recirculation amount and an ignition timing are obtained. A combustion variation is detected, and if the detected combustion variation value is equal to or greater than a predetermined value, the value of flag is set to be 1, and the exhaust gas recirculation amount and the ignition timing are reset to previous values. If the detected combustion variation value is less than the predetermined value, the value of the flag is set to be zero, and a current combustion variation manipulation correcting amount CVAR(i) is updated. If the value of flag is 1, the process is immediately terminated.
    • 检测到燃烧变化值,并且使用检测到的燃烧变化值的函数被添加到CVAR(i-1)以获得CVAR(i); 并且使用所得到的值,获得废气再循环量和点火正时。 检测到燃烧变化,如果检测到的燃烧变化值为规定值以上,则将标志值设定为1,将排气再循环量和点火正时重新设定为先前值。 如果检测到的燃烧变化值小于预定值,则标志的值被设置为零,并且更新当前燃烧变化操作校正量CVAR(i)。 如果标志的值为1,则该过程立即终止。

    • A tuner unit includes a unit board. The unit board is formed, at its lower end, with a protrusion to have a terminal pattern formed on the protrusion. A frame chassis has a side plate having, at its lower end, a protrusion having a tapered side face in one of side faces. When the protrusion of the unit board is inserted in a hole of a main board, the tapered side face is inserted while abutted against an inner edge of a hole of the main board. This urges the protrusion in a direction that the terminal pattern is brought close to the connection pattern of the main board.

    • A part holder includes a part holding portion. In this part holding portion, a leadless part is held by a part receiving portion and an engaging piece. In such a state, the leadless part is inserted in a hole formed in a printed circuit board. At this time, a resilient piece provided on a leg of the part holder comes into abutment against an inner edge of the hole, whereby the part holder is fixed by the hole. Also, the part inserted in the hole is urged onto one surface of the hole by a resilient portion of the part holder. Thus, a pattern formed on one main surface of the part is closely contacted with a pattern formed on a backside of the printed circuit board.
    • 部件保持器包括部件保持部。 在该部分保持部分中,无引线部分被部件接收部分和接合件保持。 在这种状态下,将无引线部分插入形成在印刷电路板上的孔中。 此时,设置在部件支架的腿部上的弹性件抵靠孔的内边缘,由此通过孔固定零件保持器。 此外,插入孔中的部分通过部件保持器的弹性部分被推压到孔的一个表面上。 因此,形成在该部件的一个主表面上的图案与形成在印刷电路板的背面上的图案紧密接触。
