    • A system and method for efficiently regulating the fuel consumption of a variable speed combustion engine used to control loads such as a hoist motor in a mobile gantry crane based on load motor speed commands issued by a crane operator. The system and method can rely on a programmable logic controller to issue engine fuel commands to regulate engine speed based on interpolations derived from data representing the relationship between load motor voltage and engine speed and data representing the relationship between engine speed and engine power capacity. The method may also be used in modified form by combustion engines which need digital fixed speed commands.
    • 一种用于根据起重机操作者发出的负载电动机速度指令,有效地调节用于控制诸如起重电动机等起重电动机的负载的变速内燃机的燃料消耗的系统和方法。 该系统和方法可以依赖于可编程逻辑控制器来发布发动机燃料命令以基于从表示负载电动机电压和发动机转速之间的关系的数据和表示发动机转速和发动机功率容量之间的关系的数据导出的内插来调节发动机转速。 该方法也可以以需要数字固定速度命令的内燃机以改进形式使用。
