This equates to an unprecedented 17.6:1 deep-throttling capability, which means this cryogenic engine can quickly throttle up and down.

这相当于达到了空前的17.6:1深度节流能力，意味这台低温发动机能快速控制节流。

A well-adjusted engine will have a stable idle and will not surge up and down after the throttle is closed.

一个完美的调整引擎将有稳定的怠速，收油门转速会上上下下都是不正确的。

Let the engine run for about 30 seconds on idle to allow it to warm up and then advance the throttle slowly.

让引擎怠速跑大约30秒让它慢慢地温俥后才慢慢”吹油”加速。
