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-209 is designed for the commercial launch market in China with reusability in mind. [2] It can be reused at least 30 times and can be restarted at least 3 times during the mission with deep throttle capabilities. [3] The engine hot fire test was successfully completed in February 2023. [4]
The Ricoh WG-20 is a digital compact camera announced by Ricoh on February 5, 2014. It replaces the Pentax WG-10 [ 1 ] and is rated as "waterproof to 33 feet, shockproof from drops of up to five feet, coldproof to 14 degrees Fahrenheit and crushproof, withstanding up to 220 foot-pounds of force" by its manufacturer.

The YF-90 is a liquid cryogenic rocket engine burning liquid hydrogen and liquid oxygen in a staged combustion cycle. It is China's first hydrogen-oxygen engine to use the staged combustion cycle and is expected to be used for the second stage of the Long March 9, which is a three-stage rocket with boosters.
The second YF-23 (left), nicknamed “Spider”, was powered by two YF120 engines. Due to the ATF's increasing weight during development from 50,000 lb (22,700 kg) to 60,000 lb (27,200 kg), thrust requirement was increased by 20% to the 35,000 lbf (156 kN) class in order to meet performance requirements.
The Ricoh WG-30 is a rugged, waterproof digital compact camera announced by Ricoh on October 8, 2014. It is the successor of the Ricoh WG-20.The main advance is the backside-illuminated sensor that also increases resolution from 14 to 16 megapixels compared to the previous model.
The YF-40 is a Chinese liquid rocket engine burning N 2 O 4 and UDMH in a gas generator cycle. It has dual gimbaling combustion chambers. Originally it was developed for the Long March 1D second stage. [ 6 ]
