Keyword:  空气滤清器气门间隙螺钉松动调整螺钉比油耗空滤器进气管道进气量入第间歇地;
Abstract: <正> 空滤器为何冒黑烟一上海-50型拖拉机作业时,空气滤清器内发出轻微的"嗵嗵"声,继而响声加重,接着便间歇地往外排浓密黑烟,随即,比油耗增加,功率下降。检查后发现,发动机第二缸气门调整螺钉松动了。由于调整螺钉松动,致使第一缸排气门间隙变大。这样,第二缸排气终了时,气缸内余压也随气门间隙变大而增高。当第二缸气门打开时,废气便从空气滤清器排出,致使空气滤清器发出"嗵嗵"声并不断加重。因进气管道内气流惯性倒逆,使其余各缸进气量减少并吸入第二缸的废气,这样,空气滤清器和排气管都排出浓密的黑烟。调整紧固气门调整螺钉后,故
