Fuel purifier for diesels
Dieselcraft Fluid Engineering, Auburn, Calif. |
The company says its new compact fuel
purifier removes more than 99 percent of the water and over 95 percent of
the natural contaminates found in diesel fuel. This is all done without
the use of replaceable, changeable, or cleanable filter elements. There
are no moving parts, except the fuel inside the purifier. This purifier
is based on a surface tension principle and rotational fluid motion, also
known as cyclone separation. Since diesel fuel and water have different
surface tension as well as density, when a mixture of the two is spread
over a large area, water droplets and large solids will separate from the
fuel. The clean fuel is drawn out of the unit and into the primary fuel
filter of the system. Water and contamination are drained from the bottom
of the unit. This process continues as long as the engine fuel pump is operating.
Dieselcraft Model 2006-1 is designed for engines with 1/4- and 5/16-in.
