重型CNG混合动力城市客车能耗试验分析

Analysison Energy Consumption Test of Heavy Duty CNG Hybrid City Buses

对我国现行的重型车能耗限值和能耗试验方法相关标准进行介绍,对传统CNG客车和CNG混合动力客车按照GB/T 19754-2015规定的方法进行测试,试验数据对比分析表明,CNG混合动力客车在能耗方面优于传统CNG客车,其节能效果主要体现在怠速、起动以及减速阶段。

The relative standards of energy consumption limits and test methods for heavy vehicles in China now is introduced. Tests are done in accordance with the GB/T 19754- 2015 to a traditional CNG bus and a CNG hybrid bus. The comparative analysis of the tests results come to the conclusion that the energy consumption performance of the CNG hybrid bus is better than the traditional CNG bus. The energy- saving effect mainly comes from the idling,starting and deceleration phases.
