分享一下易拉罐发动机的制作过程

之前我在论坛里擅自妄下断言发了一篇文章，就是探究用易拉罐做发动机壳体的可行性，这次我详细叙述一下制作过程，权当作分享吧

剪下易拉罐上的铝片，烤一下

2.把它卷一下，用胶水粘牢

3.浇筑燃料，打孔

4.安上喷头，这里用的是直喷头

下面放一下试车视频：

如果你接下来还想用蚊香点火的话，我建议你在蚊香装入发动机的一端粘上一小团燃料（鞭炮里的火药效果应该更好，当然你得确保能点燃它），让蚊香点燃这一小团燃料，燃料燃烧产生的燃气比蚊香多得多，更有利于点火。其...

我看你好像要做易拉罐大小的发动机，如果用导火索点火的话一定要注意安全。还有，你为什么对易拉罐做发动机壳体那么感兴趣呀？铝在高温下强度不高。小发动机像鞭炮一样用纸缠绕制成外壳其实都可以了，在厚度足够的情...
