A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. [1] This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared. [2]
Stability map of a hypothetical combustor. This combustor operates at conditions in which no dangerous combustion-instabilities will happen. In many practical cases, the appearance of combustion instabilities is undesirable. For instance, thermoacoustic instabilities are a major hazard to gas turbines and rocket engines. [1]
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 ...
When that happens, a fire can be hard to control. Usual methods of putting out a fire like a blanket won’t work, and because the battery is encased in steel it takes awhile for the outer box to ...

“Before the person starts cleaning up, they really should document the scene as they’re seeing it — take pictures, take videos, really try to get the entire scope of the damage,” said Omar ...
In a diesel engine, the torque and the rotational speed are controlled by means of quality torque manipulation. This means that, with each intake stroke, the engine draws in air which is not mixed with fuel; the fuel is injected into the cylinder after its contents have been compressed during the compression stroke. The high air temperature ...
Airplane gliding occurs when all the engines of an aircraft shut down, but the wings are still functional and can be used for a controlled descent. This is a very rare condition in multi-engine airliners, [1] though it is the obvious result when a single-engine airplane experiences engine failure.
