The true diesel engine, as projected by R.Diesel and represented in most low-speed engines, such as about 300rpm uses a fuel-injection system. 在这个句子中，as projected by 。。。这个as的用法能解释一下吗？谢谢
as projected by R.Diesel and represented in most low-speed engines，如果是定语从句的话，似乎缺少了is吧？？project和 represent都应该是及物动词。那如果as在句中做引导词，它在句中做什么成分呢，主语？

这个as意义用法与for相近,即引起后面的从句,不难看出,本句为as引导的非限制性定语从句,as在句中做引导词
句首可表"因为",句首倒装则表"虽然",句首作连词表"正如",句中可表"作为",其他就是特定的词组组合用法了.如as if.
一个很多的
本句是as引导的非限制性定语从句,as在句中做引导词 ,后省略了 is ,看作定语,句子分析为:
The true diesel engine, (as projected by R.Diesel and represented in most low-speed engines, such as about 300rpm )uses a fuel-injection system.主干是 engine uses system.简单了,只含了主谓宾.
