选用的空气滤芯一定要与原装发动机的动力性、经济性及可靠性匹配。 
　　（1）额定进气量 
　　滤芯技术参数中的空氯流量应大于配用发动机的额定进气量。 
　　（2）过滤材料 
　　对过滤材料有厚度、抗张力、原始进气阻力、过滤精度等要求。进口柴油朵要求空气过滤精度为5μm，国产柴油机也要还应小于20μm。高效滤纸的过滤精度为2μm，普通进口滤纸为30μm，而国产滤纸仅为80μm。 
　　（3）滤芯性能试验 现货供应P608305-P608306空气滤芯厂家
　　①流量-阻力（压降）试验 测定空气流动压力损失（流量-阻力或流量-压力分硐曲线）。 
　　②原始过滤效率试验 可计算出滤芯的集尘效率，正常滤芯的降尘率应为99%以上。 
　　③储尘能力试验和累积效率试验 滤芯积尘灰过多造成堵塞、进气阻力增大。使发动机功率下降5%或油耗上升5%时的进气阻力是一极限值，达到此值时就必须清扫或更换滤芯。试验时，进气阻力或压力降达到7—46kPa时的积灰重量即是滤芯的储尘能力，而在此试验期间的过滤效率则为累积效率。 
　　④原始进气阻力试验 进气阻力9额定时气量通过滤芯时在进、出口处的压差）不应超过3.2kPa，还则功率将下降，发动机会冒黑烟。P608305 P608306? P552060 P552070 P552071 P552071 P552072 P552073 P552075 P552076 P552077 P552077 P552251 P552290 P552819 P552849 P552850 P553000 P553004 P553110 P553191 P553240 P553261 P553293 P553311 P553314 P553315 P553335 P553404 P553411 P553548 P553693 P553712 P553746 P553771 P553823 P553825 P553925 P554004 P554005 P554016 P554017 P554018 P554018 P554071 P554071 P554072 P554072 P554073 P554075 P554075 P554081 P554104 P554105 P554166 P554347 P554403 P554407 P554408 P554408 P554620 P554620 P554685 P554731 P554744 P554744 P554770 P554860 P554925 P554925 P555095 P555150 P555213 P555240 P555396 P555461 P555570 P555625 P555627 P555680 P555823 P555935 P555961 P556001 P556004 P556005 P556007 P556064 P556245 P556245 P556287 P556700 P556915 P556916 P557111 P557207 P557373 P557380 P557382 P557440 P557624 P557624 P557841 P558000 P558000 P558162 P558250 P558329 P558425 P558467 P558615 P558712 P558792 P559418 P559430 P559624 P559740 P559850 P585282 P603857 P605552 P606720 P607362 P610903 P770027 P770035 P770132 P770133 P770145 P770149 P770169 P770180 P770181 P770184 P770197 P770198 P770234 P770367 P770371 P770372 P770373 P770414 P770491 P770494 P770495 P770520 P770541 P770576 P770616 P770678 P770709 P770735 P770736 P770737 P770738 P770739 P770800 P770819 P770834 P770836 P771006 P771073 P771268 P771502 P771504 P771505 P771506 P771508 P771509 P771510 P771519 P771521 P771523 P771528 P771529 P771530 P771531 P771536 P771538 P771543 P771545 P771546 P771549 P771550 P771553 P771557 P771558 P771561 P771562 P771563 P771571P771573 P771575 P771582 P771583 P771589 P771590 P771592 P771593 P771594 P771595 P772503 P772504 P772506 P772513 P772519 P772521 P772523 P772529 P772530 P772531 P772532 P772536 P772545 P772549 P772550 P772553 P772556 P772564 P772578 P772579 P772580 P772580 P772581 P772585 P772587 P773520 P773521 P773605 P774502 P774504 P774505 P774509 P774518 P774519 P774521 P774524 P774525 P774550 P774551 P774552 P774560 P774583 P775064 P775074 P775262 P775298 P775300 P775302 P775302 P775339 P775366 P775367 P775368 P775368 P775369 P775370 P775371 P775372 P775373 P775457 P775510 P775704 P775739 P775749
