一、本月知识学习指要１．燃料在燃烧时将化学能转化为内能，内能有两个重要应用：加热和做功．２．理解燃烧值的定义及单位，并能进行简单的计算．３．知道四冲程内燃机的构造、工作原理及热机在工作过程中能量的转化；区别汽油机和柴油机在构造及工作过程中的相同点和不同点
First, this month’s knowledge study refers to 1. When the fuel burns, it converts chemical energy into internal energy. Internal energy has two important applications: heating and work. 2. Understand the definition and unit of combustion value and perform simple calculations. 3. Know the structure, working principle of the four-stroke internal combustion engine and the conversion of the energy of the heat engine during the working process; distinguish the similar points and differences between the gasoline engine and the diesel engine in the construction and working process.
