The YF-20 is a Chinese liquid-fuel rocket engine burning N 2 O 4 and UDMH in a gas generator cycle. It is a basic engine which when mounted in a four engine module forms the YF-21 . The high altitude variation is known as the YF-22 is normally paired with the YF-23 vernier to form the YF-24 propulsion module for second stages.

The YF-215 engine has been designed to power the first stage of the Long March 9 rocket, with 26 of these engines in the first stage. [1] A successful ignition test of the pre-combustion chamber and gas generator of the engine was conducted on 12 May 2023.
Long March 12 (CZ-12) is designed as a two-stage rocket: its first stage is powered by four YF-100K 1250 KN engines using RP-1 and liquid oxygen while its second stage is powered by two YF-115 180 kN engines also using RP-1/LOX. The rocket offers two payload fairing choices, one with a diameter of 5.2 metres and another with a diameter of 4.2 ...

'Expedition') is a restartable upper stage developed by the China Academy of Launch Vehicle Technology (CALT) for the Long March rocket family. The Yuanzheng stage enables the Chinese launch vehicles to deploy payloads directly to high-energy orbits such as medium Earth orbit (MEO) and geosynchronous orbit (GSO).
The vehicle is a further development of the Long March 6, with two YF-100 engines on the first stage as opposed to one on the Long March 6, augmented by four solid rocket boosters. The Long March 6A is China's first rocket with solid rocket boosters. There also exists a shorter boosterless variant of the 6A called the Long March 6C.
