摘要
随着技术的进步以及重型车燃料消耗量限值的不断加严,我国重型商用车的行驶阻力不断下降。2012年确定的行驶阻力系数推荐值已经和目前实际行驶阻力存在偏差。通过重型商用车行驶阻力系数调查,对收集到的城市客车行驶阻力与推荐值进行比较分析,在延续GB/T 27840标准现行方案总体框架的前提下,对城市客车原有行驶阻力系数推荐值提出调整建议,进一步完善重型商用车辆燃料消耗量测试方法,增加测试结果的准确性。
With the advancement of technology and the tightening of heavy vehicle fuel consumption limits,the driving resistance of heavy commercial vehicles has continued to decline.The recommended driving resistance coefficient determined in 2012 has deviated from the actual driving resistance.In this study,we investigated the driving resistance coefficient of heavy commercial vehicles,compared and analyzed the collected driving resistance and the recommended value of city bus.Under the overall framework of the current scheme of the GB/T 27840 standard,adjustment suggestions are proposed for the original driving resistance coefficient of city bus.To further improve the fuel consumption test method for heavy commercial vehicles and increase the accuracy of test results.
