TQ-12

The TQ-12 (Chinese: 天鹊-12; pinyin: Tiānquè-12, lit. Sky Lark 12) is a gas-generator cyclerocket engine burning liquid methane and liquid oxygen (methalox) developed by LandSpace. TQ-12 is the first Chinese liquid rocket engine developed with private funding. The engine has been designed to produce 670 kilonewtons (150,000 lbf) of thrust at sea level.

Five of the TQ-12 engines were used on each of the three Zhuque-2 launches.
