How atomization of fuel affects the quality of combustion?

5) Atomization: Atomization is the process of breaking the fuel oil particles of hydrogen and carbon to extremely small droplets, which are easier to burn inside the combustion space. This is done by maintaining correct viscosity, pressure and injection components of the engine.

What is atomization of fuel oil in combustion?

LIQUID FUELS Page 2. COMBUSTION AND FUELS. THE PRINCIPLE OF LIQIUDS ATOMIZATION. 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.

What is atomization in combustion?

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.

What is liquid atomization?

Atomization occurs when a liquid jet is broken down into more or less fine droplets. The ideal spray consists of drops of the same diameter.

How can fuel atomization be improved?

Another way is to increase fuel pressure by increasing the power of the compressor, but that has not yet been tested fully and may result in engine fires. Switching to biodiesel is also known to greatly improve atomization due to ethanol’s ease of breaking down from its liquid form.

What are two problems caused by poorly atomized fuel?

Poor atomization also produces an engine that does not run well, since the mixture entering the cylinders varies on each bore and cycle. This potentially creates an unstable idle, tip-in hesitation, and a general lack of performance, along with a higher rate of fuel consumption.

What is atomization of fuel what is its need?

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. In all piston engines atomization also occurs while the fuel mixture moves through the combustion chamber. …

What causes atomization?

Air (Air Spray) Atomization Friction between the liquid and air accelerates and disrupts the fluid stream and causes atomization. The energy source for air atomization is air pressure. The operator can regulate the flow rate of fluid independently of the energy source.
