Researchers at the University of Purdue have developed new designs to reduce fuel consumption in heavy equipment machinery. These designs include eliminating valves to direct the flow of the fluid in heavy equipment and microstructure surfaces inside the hydraulic pumps to improve performance.
Research has shown that the “valveless” design can reduce fuel by up to 40%, in addition to added savings with the microstructured surface concept.
Purdue has filed patents for the new designs and is currently building a rig for further testing…
