摘  要:
阐述了电控喷射 L PG/汽油双燃料系统的组成及控制方法。使用 AVL DIGAS4 0 0 0型废气分析仪连续测量了废气排放 ,并与原机进行了比较。实验表明 ,L PG/汽油双燃料系统可以大幅降低 CO、HC排放。而稳定工况下 ,由于双燃料系统可燃混合气过量空气系数的波动较大 ,连续测量的双燃料系统 CO、HC排放波动大于原机。

摘  要:
The composition and control method of an electronically controlled injection of LPG/Gasoline dual-fuel system for a motorcycle engine were described in this paper. The emission performance of a dual-fuel engine was continuously measured by an AVL4000 exhaust tester and the results were compared with the initial petrol engine. The experimental results show that both CO and HC emissions of LPG/Gasoline dual-fuel system are greatly decreased. Furthermore, the fluctuation values of CO and HC of the dual-fuel system at steady condition is greater than that from a gasoline engine because the variation of excess air ratio in a dual-fel system is greater.
