浅析供油角度自动提前器 摘要：柴油发动机作为机械动力的提供装置，其应用领域已经遍及国民经济的各个领域。科学技术的进步，新配件，新技术的不断涌现，更促进了柴油发动机产品的推陈出新，先后出现了单缸柴油机，多缸柴油机。而作为柴油发动机的重要组成，供油角度自动提前器在柴油发动机燃烧方面起着及其重要的作用。 本课题计划从理论方面介绍供油角度自动提前器的结构组成、各部分组成的详细加工工艺、工作的基本原理和特点，以及对供油角度自动提前器的装配，测试，包装等工序做进一部的说明。 由于世界上对尾气排放的要求又是那么的严格，所以对柴油发动机的要求也在逐渐提高。能使柴油机得到充分燃烧、结构更为简单、成本价格更为便宜等因素也越来越重要。所以从制造工艺方面可以作进一步的探讨，可以先从从动盘、法兰、飞块的重新加工，各种零部件的重新组合等方面研究。 关键词：结构；加工工艺，装配，测试 Feed angle automatic advance unique feature and manufacture craft Abstract : The diesel engine took the mechanical power provides the installment, its application domain already spread the national economy each domain.The science and technology progress, the new fitting, the new technical unceasing emergence, promoted diesel engine product weeding through the old to bring forth the new, appeared the simplex diesel engine successively, multi-cylinder diesel engine.But took the diesel engine the important composition, the feed angle automatic advance is playing in the diesel engine burning aspect and the vital role. This topic plan from the theory aspect introduced the feed angle automatic advance structure composition, various part of composition detailed processing craft, the work basic principle and the characteristic, as well as to the feed angle automatic advance assembly, the test, working procedures and so on packing give a showing. Because in the world to the exhaust emissions request also is such strict, therefore is also gradually enhancing to the diesel engine request.Can enable the diesel engine to obtain full burning, the structure is simpler, the cost price is cheaper and so on the factors more and more to be also important.Therefore may make the further discussion from the manufacture craft aspect, may be first high the shifting plate, the flange, flies the block again processing, each kind of spare part aspects and so on again combination study Key words: Structure; Processing craft, assembly, test 目 录 摘要 1 绪 论 4 1供油角度自动提前器的结构 5 1.1 主要结构 5 1.2 特点 7 2
