摘　　要：介绍了电控喷射LPG/汽油双燃料系统及控制方法,并进行了系统和原机对比的排放试验及LPG喷射量对发动机性能的影响试验。试验结果表明:LPG/汽油双燃料系统可以大幅降低CO、HC排放;在稳态工况下,较小的LPG喷气量变化,对发动机混合气空燃比和动力性影响不大,而对排放性能影响较大。The composition and method of the electrically controlled injection of LPG/Gasoline dual-fuel system for motorcycle engine are introduced in this paper. The dual-fuel engine's emission performance is tested and compared with the initial petrol engine. The indicator diagrams of the dual-fuel engine with different LPG injections are measured and analyzed. The experimental results show that both CO and HC emissions from the engine with LPG/Gasoline dual-fuel system are greatly decreased. Furthermore, when LPG injection is slightly changed, both output power and air-fuel ratio of the dual-fuel engine vary slightly but the emission performance is affected greatly.
