摘要

Stemmed by ever-increasing demand on fossil fuels and increased environmental awareness to reduce carbon emissions, improving the efficiency of components and systems has been receiving paramount attention in most industries during the past few years. This is especially true in the mobile machinery industry, which produces high power equipment with relatively low energy efficiency for the most part. Mobile machines strictly employ fluid power systems owing to the superlative power density of hydraulic components. Nevertheless, no major breakthrough technologies to significantly boost the efficiency of fluid power systems have emerged, except for the recent development of a throttle-less actuation technology, known as pump displacement control (DC), which has been proven to be an energy efficient alternative and a serious contender to state-of-the-art technologies. This paper deals with analyzing the energy efficiency of a DC steering system versus a more conventional valve controlled counterpart, which conveys how effectively the two systems convert the chemical energy stored in the diesel fuel into useful mechanical energy. Experimental testing on a prototype test vehicle showed that DC steering results in 14.5% fuel savings, 22.6% productivity gain, and a grand total of 43.5% fuel usage efficiency increase.
