重庆市于2010年3月1日起实施《点燃式发动机在用汽车稳态工况法排气污染物排放限值》（ DB 50／344—2010），通过与其他省市对比、重庆市机动车保有量构成、不同车辆质量达标情况等方面，对实施DB 50／344—2010标准5年来合理性进行了评估。评估结果表明：DB 50／344—2010在制定时是合理的；DB 50／344—2010中对点燃式发动机汽车排气污染物限值I、II车辆生产时间的划分已不适应重庆市现有在用汽油车保有量的情况，有修订的必要；到2014年上半年，检测车辆各基准质量点燃式发动机轻型汽车限值I车辆达标合格率在70.0％～82.8％，限值II的车辆达标合格率在82.2％～93.4％，重型车限值I车辆达标合格率为70.4％，重型车限值II车辆达标合格率为77.2％。各基准质量轻型车排气污染物限值I基本合理，限值II宽松，可适当修订；重型车，限值I、限值II基本合理，可以不予修订。

Limits for Exhaust Pollutants from in-use Vehicle Equipped with Ignition Engine under Steady-state Loaded Mode ( DB 50/344-2010) came into effect in Chongqing since March 1, 2010.An assessment of the five years ’ implementation of the standard is carried out in this paper by comparing with other provinces , and analyzing the composition of automobile ownership and standard reaching status for various vehicles .The results showed that standard DB 50/344-2010 was feasible when it was developed , while it is necessary to be revised as the classification of vehicle producing period for exhaust pollutants limits I and II no longer fits the present status of motor vehicle ownership in Chongqing .By the first half of 2014, for light-duty motor vehicle with ignition engine , the standard passing rate of limit I and II are 70.0%~82.8%and 82.2%~93.4%respectively.For heavy-duty motor vehicle, the passing rate of limit I and II are 70.4%and 77.2%respectively.As for the light-duty vehicle, exhaust pollutants of limit I is basically feasible , while limit II is loose, and could be revised accordingly .Correspondingly , limit I and II for heavy-duty vehicle could stay out of amendment as they are basically feasible .
