能够对安装在发动机上的调速器执行的调整仅有最终低怠速设置和高怠速设置。 请参阅测试和调整, "空燃比控制 - 调整",了解检查空燃比控制(FRC)设置的步骤。

注: 将调速器从发动机上拆下并安装在 1U-7326 调速器标定试验台 上时,执行调速器的所有其他调整(包括 FRC)。 请参阅调速器维修手册, SENR6454,了解对调速器执行试验台测试和调整所需要的步骤和工具。

注: 下述调整在调速器安装在发动机上时执行:单体喷油器, 燃油正时度数 和 单体喷油器同步。 这些调整在气门室盖下执行。 请参阅下述主题了解更多信息:测试和调整, "单体喷油器 - 调整", 测试和调整, "燃油正时度数 - 调整" 和 测试和调整, "单体喷油器同步 - 调整"。

调速器的典型示例

(1) 空燃比控制(FRC)

(2) 增压管路端口

(3) 低怠速螺钉

(4) 高怠速螺钉

注: 请参阅发动机信息标牌或技术营销信息(TMI)"调速器试验台性能数据",了解正确的低怠速、高怠速和燃油设置。

低怠速调整

低怠速螺钉 (3) 在 1U-7326 调速器标定试验台 上进行初始设置。 最终低怠速调整在调速器安装在发动机上时设置。 发动机怠速运转时,松开锁紧螺母并将螺钉 (3) 调整到规定的低怠速。 拧紧锁紧螺母,然后重新检查低怠速设置。

注: 旧型调速器需要使用 1U-6672 齿条调整扳手 调整低怠速螺钉。 新型调速器需要使用 1U-7563 内六角扳手 (4 mm) 和 6V-9093 扳手 (13 mm) 调整低怠速螺钉。

高低怠调整

高怠速螺钉 (4) 在 1U-7326 调速器标定试验台 上进行初始设置。 最终高怠速调整在调速器安装在发动机上时设置。 发动机处于全油门和空载状态时,松开锁紧螺母并将螺钉 (4) 调整到规定的高怠速。 拧紧锁紧螺母,然后重新检查高怠速设置。

调速器控制调整(如有配备)

(1) 调速器轴

(2) 调速器连杆

(3) 铁芯连杆

(4) 电磁阀铁芯

(5) 电磁阀

(6) 螺栓

  1. 将铁芯连杆 (3) 与调速器连杆 (2) 对齐。

  1. 拧紧螺栓 (6) 。

  1. 将电磁阀铁芯 (4) 置于完全通电位置。

  1. 将铁芯连杆 (3) 调整到超过高怠速位置 4 ± 2 mm (0.2 ± 0.08 in) 处。

  1. 释放电磁阀铁芯 (4) 并手动将铁芯 (4) 移过铁芯的整个冲程。

  1. 检查移动中是否出现粘滞。 如果出现粘滞,对螺栓 (6) 进行调整。
