This occurs when an engine has been running at an excessive heat, normally for 15 minutes or more and the crankcase heat transfers to the carbueretor, boiling fuel before it enters the combustion chamber. Report this Word Added by: BenjyTheUltimate
Condition where liquid is trapped in line because of bend or improper installation; such vapor prevents liquid flow.
A condition in carbureted engines where excessive heat has caused the fuel in the fuel line or fuel pump to boil, blocking the flow of fuel to the carburetor and preventing the engine from starting.
A condition where vapor is trapped in a liquid line and impedes liquid flow.
a stoppage in a pipeline caused by gas bubbles (especially a stoppage that develops in hot weather in an internal-combustion engine when fuel in the gas line boils and forms bubbles that block the flow of gasoline to the carburetor)
Condition wherein the fuel boils in the fuel system forming bubbles which retard or stop the flow of fuel to the engine.
An engine performance problem due to high vapor pressure in fuel. While ethanol increases the vapor pressure of fuel, state and federal standards continue to lower vapor pressure levels—virtually eliminating vapor lock problems. Additionally, all major auto manufacturers now use in-tank fuel pumps, which are not subject to the vapor lock problems seen in older in-line fuel pumps.
Boiling of the fuel in the fuel lines due to excess heat. This will interfere with the flow of fuel in the lines and can completely stop the flow. Vapor lock normally only occurs in hot weather.
Bubbles formed in the fuel I i ne when the fuel boils because of extreme heat. These bubbles prevent the fuel from reaching the carburetor and cause the car to stop running. A wet rag will cool the line and get rid of the problem, and a piece of tinfoil wrapped around the line will prevent its recurrence in extremely hot weather. Fuel injection systems rarely experience vapor lock because the entire fuel system is kept at a fairly high pressure, thus preventing the fuel from vaporizing.
When gasoline overheats and boils inside the carburetor bowl or fuel pump of a hot engine, it ceases to flow. This can cause stalling or hard starting. This is called vapor lock, and it usually happens during hot weather. If a hot engine won't start, all
The formation of gasoline vapor in the fuel lines; bubbles of gasoline vapor usually restrict or prevent fuel flow to the carburetor.yVehicle Speed Sensor(VSS)z‚d‚b‚l‚É‘¬“xî•ñ‚ð‘—‚éƒZƒ“ƒTBƒXƒs[ƒhƒ[ƒ^•t‹ß‚É‚ ‚é‚Í‚¸B
Disruption of fuel movement to a gasoline engine carburetor caused by excessive vaporization of gasoline. Vapor lock occurs when the fuel pump, which is designed to pump liquid, loses suction as it tries to pump fuel vapor. The engine will usually stall, but in less severe cases may accelerate sluggishly or knock due to an excessively lean fuel mixture. Automotive engines are more likely to experience vapor lock during acceleration that follows a short shutdown period. Vapor lock problems are most likely to occur in the late spring on unseasonably warm days, before the more volatile winter grades of gasoline have been replaced by the less volatile spring and summer grades (see volatility). Vapor lock can also occur in other types of pumping systems where volatile liquids are being handled.
