摩托车二冲程发动机怠速排放和油耗的控制

Idling Emission and Consumption Control of Two Stroke Motorcycle

本文以国产250型摩托车1E65FM汽油机为试验对象,明确控制摩托车二冲程发动机怠速排放和油耗的首要措施是保证化油器质量,重要对策是实施化油器综合流量管理,但原PZ26型化油器的结构缺陷影响这一对策的实施。在分析基础上提出了PZ26(2)型新型化油器的物理模型,新型化油器并能在现有工艺条件下实现整机怠速排放和油耗的控制。本文简要阐述这一攻关工作的科研思路,并作了讨论探索。

Taking domestic 250 model IE 65 FM gaslion engine motorcycle as testing subject, main measures on control engine idling emission and consumption are raised. New carburetor physical model of PZ 26(2) model is also put out in this paper.
