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 ...
Moving the fuel pump to the interior of the tank helps prevent vapor lock since the entire fuel-delivery system is under positive pressure and the fuel pump runs cooler than it would be if it is located in the engine compartment. This is the primary reason that vapor lock is rare in modern fuel systems. For the same reason, some carbureted ...
Bent connecting rod after Hydrolock Same connecting rod, turned 90°. Hydrolock (a shorthand notation for hydrostatic lock or hydraulic lock) is an abnormal condition of any device which is designed to compress a gas by mechanically restraining it; most commonly the reciprocating internal combustion engine, the case this article refers to unless otherwise noted.
The gas, being less dense than the liquid, rises to any high points. This phenomenon is known as vapor lock, or air lock. Flushing the system with high flow or pressures can help move the gas away from the highest point. Also, a tap (or automatic vent valve) can be installed to let the gas out.
A Florida driver is filmed pulling away from a gas station and ripping out a pump in the process.. The driver apparently got into their vehicle unaware that the nozzle was still in their car. The ...
Dieseling is not nearly as common as it once was, because it most commonly occurs in engines equipped with carburetors. The vast majority of vehicles manufactured after 1987 are fuel-injected: the injectors and high-pressure fuel pump immediately cease supplying fuel to the cylinders when the ignition is switched off.
Most modern pumps have an automatic cut-off feature that stops the flow when the tank is full. This is done with an auxiliary sensing tube running from just inside the mouth of the nozzle to a Venturi pump in the pump handle. A mechanical valve in the pump handle detects a change of pressure and closes, preventing the flow of fuel. [28] [29]
