“发动机构造和原理”课程主要是介绍工程机械发动机各个机构、系统的构造和基本工作原理,其中供油系统的主要部件——化油器是汽油发动机的心脏,它主要是按照喷散和雾化的原理来完成汽油的汽化和形成可燃气体。在学习这部分的内容时,学生往往感到不易理解,本文结合教学实践进行一些探讨。 发动机一般有五种工况,需要配备可满足不同油、气量的供油系统,壳体中纵横交错的油道和气道加上必需的零件和操纵机构形成了化油器特殊复杂的结构。显然,发动机工作的好坏主要取决于化油器,例如汽车从静止状态到开动,化油器要配备较浓的可 The course of “Engine Structure and Principle” mainly introduces the structure and basic working principle of each mechanism of engine, the system and the basic working principle. The main component of oil supply system - carburetor is the heart of gasoline engine. It is mainly based on spray and fog The principle of gasification to complete the vaporization of gasoline and the formation of combustible gas. When learning this part of the content, students often feel not easy to understand, this article with some teaching practice. The engine generally has five conditions, you need to meet with different oil and gas supply system, the criss-cross the oil and airways in the shell with the necessary parts and operating mechanism to form a special complex carburetor structure. Obviously, the work of the engine depends mainly on the quality of the carburetor, for example, the car from rest to start, carburetor to be equipped with a strong
