Feng Shui Engine (device)

The Feng Shui Engine (風水エンジン, Fuusui Enjin) is a miniaturized Tanden Engine which is the size of a human eyeball. The only known owner of this object is Juri, who uses it in both of her Ultra Combos in Super Street Fighter IV, even being the focus of one.

Capabilities
The limits and full power of the engine itself have not yet been fully revealed; however, during her second Ultra Combo in Super Street Fighter IV, the engine gives her an amazing speed boost. In the Super Street Fighter IV animation The Ties that Bind, Juri easily defeats Chun-Li, Guile and Cammy all at once while under its influence. The anime also shows that it cannot be used for extended periods (likely reflected in the time limit of her first Ultra Combo in the games); this limitation was removed later in the animation by S.I.N. scientists.

As a plot element
The Feng Shui Engine was implanted in Juri's left eye socket when she was a young teenager. It acts as a replacement for her left eye, which had been badly damaged and went blind when her family was attacked and her parents assassinated by Shadaloo, under the orders of M. Bison. Developed by Seth, the device gave Juri incredible abilities, vastly exceeding that of an ordinary fighter, along with powerful ki abilities.

As a special attack
Juri uses the eponymous eye during her first Ultra Combo in Super Street Fighter IV.

Description
Executed by pressing two quarter-circle forward motions and all three punches, the move causes the Revenge Gauge to become a timer, which counts down from the point it had been filled to. Until the time elapses, Juri draws upon the power of the Feng Shui Engine inside her eye and becomes capable of cancelling and chaining many more attacks than she could otherwise, which means that almost all of her attacks are combo-able. This state is sometimes referred to as "Custom Combo Mode" - also not unlike Rose's Soul Illusion in Street Fighter Alpha series -, since Juri can create almost any combo she pleases, although not to the extent of Yun and Yang under the influence of Genei Jin and Seiei Enbu respectively.
