Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
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]
British Airways Flight 38 crash-landed at London Heathrow in 2008 after its fuel lines became clogged with ice crystals.. In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading ...
Narcosis results from breathing gases under elevated pressure, and may be classified by the principal gas involved. The noble gases, except helium and probably neon, [2] as well as nitrogen, oxygen and hydrogen cause a decrement in mental function, but their effect on psychomotor function (processes affecting the coordination of sensory or cognitive processes and motor activity) varies widely.
China eventually developed domestic powertrains, which led to the creation of the MBT-3000 program for export customers. MBT-3000 was the successor of the Type-90II (MBT-2000) export tank. [ 3 ] The MBT-3000 project later named as VT-4 began development in 2009 as a co-operation with the First Inner Mongolia Machinery Factory and other companies.
A pressure drop as small as 100 Torr (13 kPa), which produces no symptoms if it is gradual, may be fatal if it occurs suddenly. [77] One such incident occurred in 1983 in the North Sea , where violent explosive decompression from nine atmospheres to one caused four divers to die instantly from massive and lethal barotrauma . [ 79 ]
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.

The Type 63 (industrial designation YW531) is a Chinese armoured personnel carrier that entered service in the late 1960s. It was the first armoured vehicle designed in China without Soviet assistance. [1] The design is simple and is comparable to other APCs of its time such as the M113. Approximately 8,000 all types and variants were produced ...
