美国Harmon电子设备公司认为,铁路部门通过自动关断空转柴油机,可以大量地节省燃油费用。当不需要机车运转时,许多铁路部门的作法是手动停机,但Harmon公司认为,手动停机操作需耗费机组人员太多的时间。为此该公司决定采用自动停机法,以最大限度地节约燃油费用,并推出他的自动起动/停机系统。该公司估计一台标准的大功率机车(这种机车的柴油机空转时间差不多占其总工作时间的一半)采用这种装置后每年能够节约几千加仑燃油。 Harmon公司的起动/停机装置安装在空气制动装置单元中,其装置设有各种用于监视诸如水温、环境温度、柴油机水温,换向器手柄 Harmon Electronics of the United States believes that the railway sector can save fuel costs significantly by automatically shutting down idling diesel engines. Many railway departments shut down manually when locomotives are not in service, but Harmon believes manual shutdowns consume too much crew time. To this end, the company decided to adopt an automatic shutdown method to minimize fuel costs and introduce his automatic start / stop system. The company estimates that a standard high-powered locomotive, which uses half the idle time of a diesel engine, can save thousands of gallons of fuel annually with this device. Harmon’s start / stop unit is installed in the air brake unit, which is equipped with various devices for monitoring such as water temperature, ambient temperature, diesel engine water temperature, commutator handle
