摘　　要：本文从能量角度出发,分析了二冲程微型摆式内燃机作为微型发电系统动力源时,系统载荷对内燃机的性能影响。通过分析指出,系统质量载荷由系统转动惯量形成,随质量载荷的增加,内燃机压缩比随之增加;而外载荷主要取决于电载荷系数,随外载荷的增加内燃机压缩比将减小。质量载荷利于提高内燃机输出功率,但受限于压缩比。在一定外载荷下,内燃机可获得最大输出功率。From the energy point of view,the system load impacted on the engine performance is discussed,when a two-stroke micro free swing piston engine（MFSPE） is used as a micro-power source.Through analysis results,the system mass load is formed by the system moment of inertia.With it increased,the compression ratio of MFSPE will increase.The outer load depends mainly on the electric load factor.With it increased,the compression ratio of MFSPE will decrease.The system quality load can help to increase the net power of MFSPE,but its growth is limited to the compression ratio.Under a certain external load,the maximum output power of MFSPE can be obtained.
