Questions about using DFT #l500 "Hammerdown"

How does DFT #1500 " Hammerdown" help vaporize fuel?

Improved vaporization of diesel and heavy fuels is accomplished in two ways:
        (a) Carbon deposits around injector orifices distort the designed spray pattern resulting in poor fuel atomization. By removing and preventing the formation of carbon deposits, DFT #1500 "Hammerdown" insures that the fuel is atomized as designed by the equipment manufacturer, instead of in a distorted stream as occurs when orifices are obstructed.
        (b) DFT #l500 "Hammerdown" acts as a surfactant to break fuel into 2 microns or smaller sizes as they are injected into the combustion chamber, which enhances fuel/air mixing, resulting in a more complete combustion of fuel.

Is the cetane number increased using DFT #1500 "Hammerdown"?     

Increases of the cetane number indicate a shortening of the time required for ignition to begin in the combustion chamber. Typical cetane enhancers for diesel fuels, such as amyl nitrate, are high volatility products that shorten the ignition delay but do nothing to ensure full conversion of all of the fuel into heat energy. This type of product will cause high pressure peaking and its attendant problems. DFT #1500 "Hammerdown" does not contain any cetane enhancers. However, its action is such that ignition and burn characteristics of fuels containing DFT #1500 "Hammerdown" are similar to those of fuels with higher cetane numbers, but without high pressure peaks.

What happens to lube oil dilution by fuel when using DFT #1500 "Hammerdown"?     

Lube oil dilution by fuel oil occurs when piston rings fail to prevent 'blow by' because they cannot float freely. (A small amount of 'blow by' will occur even in new engines; excessive 'blow by' should be avoided,) When the rings are kept free of carbon deposits by using DFT #1500 "Hammerdown", 'blow by' will remain within design parameters and excessive dilution of the lube oil will not occur.

How is the exhaust back pressure affected using DFT #1500 "Hammerdown" and why?

High exhaust back pressure is a result of explosive combustion rather than progressive burning caused by using poor quality diesel fuels. The consequences are burned valves, and blown out exhaust systems. DFT #l500 "Hammerdown" causes the combustion process to be more smooth and to have lower peak pressures, resulting in more complete burning, power being closer to design, and longer equipment life.

How is low pressure corrected using DFT #1500 "Hammerdown"?     

Low compression pressure indicates a mechanical problem, One cause can be failure of the compression rings on the piston to float freely and conform to the slight irregularities of the cylinder wall (Other causes are broken rings, stuck valves, burned pistons or valves, scored cylinders, and cracked heads.) Rings fail to float freely when carbon builds up behind and around them. DFT #1500 "Hammerdown" removes and prevents such build up so that design compression pressures can be achieved. Low combustion pressure also may indicate mechanical problems. However, poorly burning fuels and/or fuels with low heating values can give low combustion pressures. By helping fuels to burn completely, DFT #1500 "Hammerdown" helps to minimize low combustion pressures from such fuels.

What happens with the aromatics using DFT #l500 Hammerdown and why?     

The cyclic structure of aromatics inhibits intimate mixing of carbon and oxygen to assure consistent and complete reaction. This results in erratic and unusually high combustion pressures, smoke, and carbon deposits. DFT #l500 "Hammerdown" assists the oxidation process both physically and chemically.
