Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
191 words
A fuel processor means for use with diesel engines on diesel trucks, automobiles, and the like, and whereby said fuel processor is operative to preheat the diesel fuel and to separate out water-impurities from the diesel fuel, comprising, a vertically oriented elongated tubular vessel means for separating water out of the fuel, inlet conduit means near the top of said vessel to introduce hot engine coolant liquid to the vessel, another conduit means passing through a central portion of said vessel for transmitting the hot coolant liquid therethrough, outlet conduit means for recirculating the coolant liquid back through the engine cooling system, a second inlet conduit means for introducing fuel to the interior of the vessel near the midpoint thereof for flow therethrough and such that this inlet is above the level of water-impurities being collected in the vessel, a second outlet conduit means for the fuel located near the top of the vessel for transmitting the water-free fuel to the engine, drain means at the bottom of the vessel for draining out water-impurities which collect therein, and means near the top of the vessel for venting the vessel when desired.
Claim 2
