What is a vapor carburetor?
A vapor carburetor is an invention meant to vaporize gasoline before it goes through the engine so that it may burn more efficiently and completely. A carburetor ensures the proper mixture of gasoline and air enters an engine for combustion. The carburetor is no longer used in most newer cars.
Does a carburetor vaporize fuel?
Carburetor works on the principle of vaporization of liquid gasoline fuel adiabatically before its introduction into the engine cylinder. This vaporization is achieved by allowing atmospheric air, induced by engine suction, to pass through the fuel [1] .
How the fuel is vaporized inside the carburetor?
In addition, the heat of the intake valve helps the fuel to vaporize. The accelerator pump discharge is a solid stream of fuel, and without the aid of a collision against a hard surface, very little of the fuel would become atomized by the tearing created by the air flowing through the carburetor.
What are fuel vapors?
Naturally, gasoline vapor comes from gasoline. Vapor is a substance produced by some liquids; part of the liquid diffuses into the air, retains some of the properties of the original liquid, and becomes flammable. Gasoline produces vapor at a very low temperature, -40° Fahrenheit, which is known as its flashpoint.
How do you turn gas into vapor?
Heat is necessary for gasoline to vaporize. A general rule that still applies to modern gasoline is that, at a temperature of 60 degrees Fahrenheit, only 50 percent of the liquid gasoline converts to vapor. At near freezing temperatures, that percentage declines to approximately 20 percent.
Why is my carburetor cold?
Carburetor icing is caused by the temperature drop in the carburetor, as an effect of fuel vaporization, and the temperature drop associated with the pressure drop in the venturi. If the temperature drops below freezing, water vapor will freeze onto the throttle valve, and other internal surfaces of the carburetor.
How do you stop fuel vapor lock?
The first step in preventing vapor lock is to rout fuel lines away from exhaust parts, heater hoses, etc. You can also use Heat Shields where possible. Another option is to install an Electric Fuel Pump near the tank. This pressurizes most of the fuel in the lines.
How do you know if your car is vapor locked?
Symptoms of vapor lock in cars include engine stalling and difficulty starting, engine running rough, potential misfiring, and engine acceleration and hesitation. Your vehicle’s fuel system needs to operate under a certain pressure.
