in internal-combustion engines, the mixing of fuel with air or some other oxidizer within the engine in order to achieve complete and rapid combustion of the fuel.
How does a fuel atomizer work?
In this process, fuel is forced through a small jet opening under extremely high pressure to break it into a fine misted spray. From here, the mist is mixed with air (emulsified) and then vaporized into a rarefied form appropriate for use by an internal combustion engine.Feb 17, 2019
Why is atomization needed?
The Importance of Carburetors Without proper and efficient atomization, liquid fuel can be heavily wasted in the process of combustion or even worse gum up the engine to where it won't work. That's why it's important to check your vehicle's carburetor regularly if you feel fuel performance is beginning to slip.Feb 17, 2019
What is atomization and why is it important in fuel injection?
Fuel atomization—ensuring that fuel atomizes into very small fuel particles is a primary design objective for diesel fuel injection systems. Small droplets ensure that all the fuel has a chance to vaporize and participate in the combustion process.
What is an atomiser in an engine?
Atomization is the process of converting bulk liquid into fine droplets. Efficient atomization produced by particular atomizer is an important and the basic requirements in the various combustion applications (Gas turbine, Liquid rocket engine, ramjet, scramjet propulsion etc.).
What is the purpose of an atomiser?
An atomizer is a device that produces a fine spray from a liquid. Most combustors employ an atomizer in which fuel is forced under high pressure through an orifice. The function of any atomizer is to produce as homogeneous a spray as possible. An atomizer is a device that produces a fine spray from a liquid.
What is atomization process?
Atomization. Atomization, also called the spraying method, is a process in which molten metals are broken into small drops of liquid by high-speed fluids (gas as air or inert gas; liquid as water) or fluids with centrifugal force, and then solidified into powder.
Why does gasoline have to be atomized?
The carburetor's job is to prepare the gasoline to make that phase change from a liquid to a vapor. If the fuel is not atomized sufficiently, then the other steps cannot take place properly. So first and foremost, the gasoline needs to be broken into small particles.
How is fuel atomised?
Atomisation is the process whereby bulk liquid is transformed into a collection of drops. This transformation goes through the break-up of liquid jet into number of filaments, which in turn transform into droplets.
How is diesel fuel atomized?
Abstract: Mixture preparation in diesel combustion starts with spray formation after the fuel leaves the injection nozzle. The fuel spray atomizes into droplets, vaporizes, and mixes with air. ... In-cylinder mixing of fuel and air can be further enhanced by measures downstream or upstream of the lift-off length.
