Over the past several years, EPA has evaluated idle reduction technologies/devices as part of grants, cooperative agreements, emissions testing, engineering analyses, modeling, demonstration projects and external peer reviewed reports to study the effects of idling on air quality, fuel consumption and driver health.  Based on this evaluation and research, EPA has determined that a variety of idle reduction technologies save fuel and reduce emissions when compared to idling the main engine.  9 b$ T. l!

Verified Aerodynamic Technologies
1 M& c' L0 F$ s0 z9 d. z: RTrailer aerodynamic technologies can minimize aerodynamic drag and maintain smoother air flow over the entire tractor-trailer vehicle.  Trailer aerodynamic devices include gap fairings that reduce the gap between the tractor and the trailer to reduce turbulence, trailer side skirts that minimize wind under the trailer, and trailer rear fairings that reduce turbulence and pressure drop at the rear of the trailer.  EPA determined that using these trailer aerodynamic fairings in combination with one another (or, in a few cases, when used alone) have the potential to provide an estimated 5% or greater reduction in fuel use relative to the truck's baseline, when used in conjunction with an aerodynamic tractor on long haul class 8 trucks, in highway type operation. This reduces NOx emissions, saves over 800 gallons of fuel, and eliminates over 9 metric tons of greenhouse gas emissions per year.  Actual fuel savings depends upon the aerodynamic effectiveness demonstrated by each individual product, and truck operation.  To reduce NOx, greenhouse gases and improve fuel efficiency, legacy fleets can be retrofitted with aerodynamic trailer fairings, or the fairings can be provided as new equipment options.

基于轮胎厂和EPA测试研究提供的数据, EPA决定 对于可以减少热排放和节能3%或更多的轮胎花纹,作为5轴长途8级卡车的“畅销”并新轮胎。包括双胎并装和单个的宽轮胎(单个宽基轮胎在驱动或拖车的一端取代并装的双胎, 也使18轮改为10轮)。低滚动阻力轮胎可以用于轻的铝制轮辋来进一步节能。! d! s$ U+ |2 I, v/ S7 P$ B; {

滚动阻力系数的英文名称:Coefficient of Rolling Resistance   
2 ?1 t1 V7 W. }4 R2 q7 ~) K. o2 r/ ]/ @9 [4 a8 _
滚动阻力系数,是用来计算滚动阻力的一个系数。它是车轮滚动时所需的推力(即滚动阻力)与车轮载荷的比值。它的数值,是由试验测定的。实践表明,它与路面的种类、轮胎的构造、材料、轮胎压力及行驶车速都有密切的关系。
