关 键 词：Commercial powertrain Fuel efficiency CO2 reduction
摘 要：Objective Already for many years,fuel consumption and operating cost were the major technology drivers for commercial ***,in order to achieve agreed CO goals and to reduce the dependency on crude oil,governments are implementing CO or fuel consumption *** more,reduction of fuel consumption and consequently low operating costs are continuously an important focus for manufacturers and owners of commercial *** powertrain technologies,which will further reduce fuel consumption,are able to combine these three drivers,to reduce CO emission,to reduce the dependency on crude oil and to address the need of lower total cost of ownership of the owners of commercial *** The efficiency of commercial powertrains can be significantly increased in *** potentials for improvement are seen specifically in those technologies,which are able to provide a global optimum of the whole powertrain system,from engine to exhaust aftcrtreatment to cooling system up to transmission and the final *** total a fuel efficiency potential of20%is seen for long haul *** AVL has developed a whole line of technologies,which can be implemented to the commercial powertrain in the future to address the requirements *** individual measures are the optimization of the balance between engine and aftertreatment systems,reduced engine friction by advanced thermal management systems,reduced parasitic losses of the auxiliaries in real life driving cycles,conversion of exhaust energy in driving power,application of new and advanced transmission technologies and shift strategies as well as degrees of electrification of the ***,alternative fuels provide another field of CO friendly technologies as well as reduced operating *** specifically,the availability of local resources drive short term *** paper will compare the individual saving potentials of these technologies,will rate it against criteria
