Although you can burn biocrude directly in a diesel engine, you should attempt it only if you no longer have a need for the engine.

当然，也可以在柴油发动机里直接燃烧生物原油，可只有不在指望使用这个发动机的时候你才敢放胆一试。

Deconstruction at higher temperatures (300 to 600 degrees C) produces a biocrude, or bio-oil, that can be refined into gasoline or diesel.

温度再高一些的工艺（300~600摄氏度）得到的则是生物原油（biocrude或bio-oil），可进一步提炼成汽油或柴油。

This biocrude could be fed directly into existing oil refineries, without any need to modify them.
