The J-10A is powered by a single Russian Lyulka-Saturn AL-31FN turbofan engine giving a maximum static thrust of 12,500 kgf (123 kN).
The AL-31FN is based on the AL-31F which was designed for a twin engine aircraft such as the Su-27, to fit the smaller J-10 the engine parts have been moved and re-designed to fit the smaller engine bay in the J-10.

The J-10 was intended to be powered by the Chinese WS-10 Taihang turbofan, but development difficulties forced the J-10A to use a Russian engine instead.
Future J-10 will likely be equipped with an improved WS-10 type engine designed specifically for it, as the Chinese aeroengine industry matures and political/military pressure to indigenize increases.

In April 2014, China have entered into a contract with NPO Saturn to purchase the upgraded AL-31FN Series 3 that provides 13,700 kgf thrust and a 2,250-hour service life for future deliveries.
Prior, the AL-31FN Series 3 had accumulated 750 hours of test operation on the J-10 aircraft in a test programme.

In Jan 2018, an image has emerged on Chinese online forums showing a Chengdu Aircraft Industries Company J-10 multirole fighter aircraft powered by what may be an engine featuring a thrust vector control (TVC) nozzle.
Newer aircraft also use a diverterless intake, a design intended to reduce complexity and often reduces radar cross signature as well.

In November 2018, a J-10B powered by WS-10 thrust vector control (TVC) publicly displayed at the Zhuhai AirShow and made a Pugachev's Cobra action.
