Most engines require one or more systems to start and shut down the engine and to control parameters such as the power, speed, torque, pollution, combustion temperature, and efficiency and to stabilise the engine from modes of operation that may induce self-damage such as pre-ignition. Such systems may be referred to as engine control units.
Following an engine shutdown, a precautionary landing is usually performed with airport fire and rescue equipment positioned near the runway. The prompt landing is a precaution against the risk that another engine will fail later in the flight or that the engine failure that has already occurred may have caused or been caused by other as-yet unknown damage or malfunction of aircraft systems ...
The fuel system as explained above is one of the two systems required for starting the engine. The other is the actual ignition of the air/fuel mixture in the chamber. Usually, an auxiliary power unit is used to start the engines. It has a starter motor which has a high torque transmitted to the compressor unit. When the optimum speed is ...
This system works very well in getting rid of crankcase vapors which are harmful to the engine. As per the earlier engines, the road draught tube system also created pollution and objectionable odors. [1] The draught tube could become clogged with snow or ice, in which case crankcase pressure would build and cause oil leaks and gasket failure. [2]
Crew shut down of engine due to low oil pressure; remaining two engines failed due to loss of oil. After gliding for five minutes, one shut-down engine was successfully restarted. Aircraft made emergency landing at Miami International Airport; the sole running engine could not generate enough thrust to taxi aircraft to gate. 0: 172 23 July 1983

An emergency switch in Japan. On railways, [1] an emergency stop is a full application of the brakes in order to bring a train to a stop as quickly as possible. [2] This occurs either by a manual emergency stop activation, such as a button being pushed on the train to start the emergency stop, or on some trains automatically, when the train has passed a red signal or the driver has failed to ...
Howmet's roots go back to 1926, when Austenal, a company that manufactured materials for dental appliances, was founded. Its founders, Reiner Erdle and Charles Prange, worked to improve investment chrome base castings using two separate investments: The first coating, named "protective coat", gives a smooth finish.
