Vapor lock Definition from Business & Finance Dictionaries & Glossaries
Glossary of petroleum Industry
A condition that exists when a volatile fuel vaporizes in an engines fuel line or carburetor preventing the normal flow of liquid fuel to the engine. To handle gas lock or vapor lock the gas must be bled off the system by removing a line or loosening a connection, or the fines and carburetor cooled sufficiently to condense the gas back to a liquid.
Vapor lock Definition from Science & Technology Dictionaries & Glossaries
Dictionary of Automotive Terms
This is an unwanted condition where bubbles of air form in the fuel line caused by boiling or vaporizing of the fuel in the lines from excess heat. The boiling will interfere with the movement of the fuel and the air bubbles which form will in some cases, completely stop the flow. Sometimes it will cause the float chamber to overflow which floods the carburetor and result in an over-rich mixture that can cause stalling of the engine when the accelerator is depressed. Fuels containing alcohol have lower boiling points and many old-car owners have installed more-powerful electric fuel pumps which overcome vapor lock tendencies of these fuels by pushing them through the air bubble. A wet rag will cool the line and get rid of the problem. To prevent the problem in hot weather, some mechanics wrap tinfoil around the fuel lines to reflect the heat away.
Technical English by wpv
