System Configuration Parameters

Usage:

CS-56B 437


系统配置参数影响发动机的排放或发动机的功率。 配置参数在工厂进行编程设定。 通常,系统配置参数在发动机整个使用寿命中不需要进行修改。 如果更换电子控制模块(ECM)的话,则必须重新编程设定系统配置参数。 如果只是更改 ECM 软件,则不必重新编程设置系统配置参数。 修改这些参数时需要使用出厂密码。 以下是对系统配置参数的说明。

"满载设定值"

"Full Load Setting(满负荷油量设置)"是一个代表燃油系统调整量的数值,这种调整是在出厂时进行,用以微调燃油系统。 如果更换了 ECM,必须对"满负荷油量设置"重新编程,以防止诊断代码 268-02 变为激活状态。

"全扭矩设定值"

"全扭矩油量设置"与"满负荷油量设置"相类似。 如果更换了 ECM,必须对全扭矩油量设置重新编程,以防止诊断代码 268-02 变为激活状态。

"额定值"

"Rating(额定)"是用来防止特定发动机使用不正确额定功率和/或额定排放的代码。 每个额定功率和每个排放认证与其他所有的额定功率和排放认证具有不同的代码。 这是用来防止特定发动机使用不正确额定功率和/或额定排放的代码。 每个额定功率和每个排放认证与其他所有的额定功率和排放认证具有不同的代码。

更换 ECM 时,此额定互锁代码必须与 ECM 中存储的代码相符。 如果额定互锁代码与 ECM 中存储的代码不相符,将会同时出现以下两种情况:

  • 发动机将不运转。

  • 诊断代码 253-02 个性化模块不匹配 将处于激活状态。

注: 新额定 Interlock(互锁)将代替旧额定 Interlock(互锁)。

当替代 ECM 是用于同一发动机额定值时,不需要编程设置此代码。

如果替代 ECM 是用于不同的发动机额定值,则可能需要更改下列部件: 活塞, 燃油喷油器 和 其他部件 。 还必须修改发动机铭牌,以反映新额定值。

改变发动机额定值后,可能还需要更改一些系统,例如冷却系统或变速箱。 关于更多信息,请联系当地 OEM 代理商。

"发动机序列号"

交付新的 ECM 时,ECM 中的发动机序列号没有进行编程设置。 应对"发动机序列号"进行编程,以与压印在发动机信息标牌上的发动机序列号相配。

"ECM Software Release Date(ECM 软件发布日期)"

此参数由额定interlock(互锁)定义,此参数不可编程设置。 "ECM Software Release Date(ECM 软件发布日期)"用来提供软件的版本。 此日期可以监控用户参数和软件更改层次。 此日期按月年(JAN09)的方式提供。 Jan 是指月份(1 月)。 09 是指年份(2009)。
