文摘：Hydraulic hybrid technology captures kinetic energy generated by a Class 8 refuse truck and transmits it into a high-pressure accumulator. THE INCREASING COST OF FUEL is driving the development of new technologies that can provide better efficiencies in all types of vehicles. Much of the early emphasis has been placed on passenger cars with the U.S. EPA establishing a Corporate Average Fuel Economy (CAFE) goal of 54.5 miles per gallon by 2025. One of the largest sources of energy loss in automobiles is heat. This factor accounts for 40% of the fuel energy produced from an internal combustion engine. In a previous TLT article, a new thermoelectric material was discussed that can convert automotive exhaust heat to electricity, which can help to offset the loss. The new thermoelectric material is known as a skutterudite, a crystalline material containing cobalt, rhodium or iridium in combination with phosphorus, arsenic and antimony.
