GTA Technology’s proprietary Viscon technology improves the performance of compression ignition engines as well as spark ignition engines.
It is well known that the physical properties of diesel fuel interfere with creating a uniform air/fuel mixture in the cylinder. Viscon, unlike other fuel
additives, modifies the physical behavior of diesel fuel during injection creating a more uniform air/fuel mixture at ignition and during burn.
Diesel fuel is a Newtonian Fluid and as such has physical properties which work against preparation of a uniform air/fuel mixture:
Spray from an injector nozzle contains a population of superfine, vapor-like droplets which ignite in advance of the main body of fuel and prior to complete
spray droplet penetration and mixing.
The outer edge of the injector spray cone shears into smaller droplets which lose momentum and have poor penetration into the pressurized gas in the cylinder.
Droplets in the center area of the injector spray cone grow by collision and coalescence as they contact the slower moving droplets at the leading edge of the
spray.
Droplets which reach the cylinder walls splatter and coat creating a cooled liquid film.
GTAT’s Viscon technology uses a scientific phenomenon called extensional viscosity to modify the physical properties of diesel fuel during injection and
mixture formation. Viscon eliminates the formation of superfine satellite droplets that cause early ignition before spray jet penetration and mixing has progressed. Diesel fuel droplets containing Viscon resist
shear on the edge of the spray cone and therefore maintain momentum for better penetration. Viscon containing droplets resist growth by collision and have a tendency to rebound and reflect from the cylinder wall
back into the gas in the cylinder limiting wall coating and cooling.
