欧、美排放法规规定,自2012年起,对56～129kW非道路行驶的施工机械所用柴油机,实施EUⅢB阶段和EPA Tier4I初期排放标准。我公司某款10t级出口型内燃叉车,欲换装功率为83kW符合EUⅢB阶段和EPA Tier 4I初期排放标准的原装进口柴油机。为使柴油机能够与叉车上的辅助系统匹配,我们对辅助系统进行了测试和评估。对柴油机辅助系统的测试和评估主要包括该型叉车所配装的进气系统、排气系统、冷却系统、燃油供给系统。测
Europe and the United States emission regulations, since 2012, the implementation of EU Ⅲ B stage and EPA Tier4I initial emission standards for diesel engines used in construction machinery 56 ~ 129kW off-road. A certain 10t export-type internal combustion forklift of our company is trying to replace imported diesel engine with the power of 83kW in line with EUⅢB stage and EPA Tier 4I initial discharge standard. In order to match the diesel engine with the auxiliary system on the truck, we tested and evaluated the auxiliary system. The test and evaluation of the diesel engine auxiliary system mainly includes the air intake system, exhaust system, cooling system and fuel supply system of the forklift. Measurement
