The J-10s intended engine is the Chinese Shenyang WS-10. The WS-10 suffered development difficulties and production of the aircraft went ahead with the Salyut AL-31FN as a substitute. [ 30 ] A pre-production J-10C flew with a WS-10 at the 2018 China International Aviation & Aerospace Exhibition ; the engine nozzle was modified for stealth and ...
Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. If the engine is cold, or there is an excess amount of cooling around the cylinder, [ 1 ] the fuel oil will condense and have a higher chance to end up in the ...
In April 2009, Lin Zuoming, head of AVIC, reported that the engine's quality was unsatisfactory. [9] In 2010, it was reported that reliability was also poor; the WS-10A lasted only 30 hours, while the AL-31 needed refurbishing after 400 hours. [10] The quality problems encountered with the WS-10A reflected the state of the Chinese aerospace ...
LSPI events are random and infrequent, and their effects on impacted vehicles can include very high-pressure spikes, loud knocking noises and sometimes catastrophic engine damage. [4] It's commonly known as "Detonation or Knock". Engine management systems can overcome pre ignition by the means of a knock or detonation sensor.
Letters sent to federal workers say they are being terminated "based on your performance." But workers told USA TODAY they had no performance issues.
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

Social Security has two other funding sources: benefit taxes on some seniors and interest income earned on money in the program's trust funds. But both of those are in danger right now. The ...
Pogo oscillation is a self-excited vibration in liquid-propellant rocket engines caused by combustion instability. [1] The unstable combustion results in variations of engine thrust, causing variations of acceleration on the vehicle's flexible structure, which in turn cause variations in propellant pressure and flow rate, closing the self-excitation cycle.
