Definitions
- This invention broadly relates to a new fuel processing apparatus for diesel engine powered trucks and automotive vehicles, as well as other diesel engine power installations.
- diesel fuel has a cloud point temperature (temperature at which wax crystals form) of 0° to 20° F. and a pour point temperature (freeze temperature) of from 7° to 10° F. below the cloud point temperature.
- cloud point temperature temperature at which wax crystals form
- pour point temperature freeze temperature
- the fuel delivery systems of diesel engines used in automotive applications are designed for optimum operation when the fuel is delivered to the injectors at temperatures within the range of about 40° F. to about 90° F., a temperature range encompassing normal ambient outdoor temperatures encountered in automotive vehicle operation throughout most of the year throughout most of the United States. Fuel temperatures above and below this range can adversely affect engine operation.
- a main object of this invention is to provide a new and improved fuel processor apparatus for diesel trucks and other diesel powered automotive vehicles to remove water from the diesel fuel, while at the same time providing for increased fuel economy.
- Another object of the invention is to provide a new fuel processor apparatus which includes a unique built-in but removable fuel filter element (e.g., of either the spin-on or drop-in type).
- Another object of the invention is to provide a new fuel processor apparatus which heats the fuel to promote filterability, combustion efficiency, water removal, and to reduce crystallization of fuel wax elements.
- Another object of the invention is to provide a new fuel processor apparatus which removes water from the fuel to protect the fuel pump and fuel injection components and protects fuel filter elements to extend the filter operation life.
- Another object of the invention is to provide a new fuel processor apparatus which when installed in the heater water line circuit, permits automatic operator control of heat to the fuel processor apparatus, in that the operator controls the passenger compartment heat and the fuel processor heat simultaneously.
- Another objective of the invention is to be able to utilize the heat energy or crankcase or lubricating oil from the engine--either air or water cooled--to heat the diesel fuel to obtain the benefits of this invention.
- FIG. 1 of the drawings illustrates a typical installation of the fuel processor apparatus of this invention.
- FIG. 2 illustrates the embodiment of the invention with a built-in fuel filter. (Two types--Integral or spin-on)
- FIG. 3 illustrates a front elevation view of the embodiment of FIG. 2.
- FIG. 4 illustrates a cross-sectional view taken along the line 4--4 of FIG. 3.
- FIG. 5 is a general schematic view illustrating the flow path for the diesel fuel in the embodiment of FIGS. 2-4.
- FIG. 1 illustrates a typical installation of the fuel processor apparatus generally designated 10 in accordance with the invention.
- the apparatus 10 is preferably constructed in the form of a seamless extruded aluminum vessel 12 which has a vent or filler plug 14 at the top and a drain fitting 16 at the bottom of the vessel.
- Hot coolant liquid e.g., from the heater return water line circuit or oil from engine
- the heated coolant liquid is introduced to the interior of the vessel 12 via the inlet fitting 20 and flows through the central portion of the vessel in straight-through fashion by means of flow-through conduit 22, from which it passes to the outlet conduit 24 which is connected to the vessel 12 by means of the fitting 26.
- the construction of the fuel processor apparatus 12 and and interior conduit 22 is preferably of aluminum because of its excellent heat transfer quality and compatibility with the vehicle cooling system. However, other construction materials can of course be used.
- the amount of heat added to the fuel by the processor is adjusted in accordance with the outside ambient temperature in that the driver will be operating the compartment heater at its maximum heat output in extreme cold weather conditions and normally will not run the heater when the outside temperature is above 65°-70° F. .Iaddend.
- the water-free heated fuel then passes out the outlet condut 34 via the fitting 36, and then the water-free heated fuel is introduced to a primary fuel filter 38 from which it is transmitted to the diesel engine.
- a bracket 40 and U-bolt clamping means 42, 44 can be used to suitably mount the fuel processor apparatus at any sturdy convenient location on the vehicle.
- the fuel processor apparatus 100 is constructed in the form of a generally elongated cylindrical vessel 102 which has an integral filter member 104 at the top thereof and a drain plug 106 at the bottom thereof.
- Hot coolant liquid e.g., from the heater return water line circuit
- inlet line 108 from which it assumes the flow path through the vessel 102 to pass through the interior of the vessel by means of flow through conduit 109, and subsequently it passes to the water outlet conduit 110.
- Cold or unprocessed diesel fuel from the fuel of the truck or vehicle is introduced to the apparatus 100 via the fuel inlet line 112 from which it passes into the interior of the vessel 102 by means of the conduit 113.
- the diesel fuel once passing through the internal portion of the vessel 102 is heated by counter-action and contact with the hot coolant liquid passing through the conduit 109. Due to the heat exchange action which takes place within the vessel 102 and also due to the significant difference between the specific heat of the fuel oil and the specific heat of the water contained therein, the suspended water, (as well as any ice crystals suspended in the fuel) are separated out of the fuel and settle to the bottom of the vessel 102 in a fashion similar to the operation of the FIG. 1 embodiment.
- the water-free heated fuel then passesas out of the vessel 102 by means of the conduit or passage way 115 which introduces the fuel to the filter element 104, which includes a filtering material designated 117.
- the filtration material 117 operates to remove particulate material which resides in the diesel fuel.
- the filter element 104 is a spin-on type of filter (or it could be a drop-in type filter) which is integrally connected to the apparatus 100 by means of a threaded connection 119. After the fuel has passed through the filtration material 117 the fuel exits from the filter via the conduit 121 and the fuel outlet conduit 123.
- the bottom of the vessel 102 may suitably include a transparent or see-through section designated 127 so that the collected water can be observed at the bottom of the vessel 102, thus facilitating removal of the water at periodic intervals.
- the lower length of the vessel 102 can be extended to make the overall fuel processor apparatus 100 of variable capacity depending upon the fuel requirements of the engine.
- a bracket means 125 can be used to suitably mount the fuel processor apparatus 100 at any sturdy convenient location on the vehicle.
- both embodiments disclosed have the fuel inlet (30 FIG. 1; 112, 113 see FIG. 5) located to introduce fuel into the apparatus approximately at the midpoint of the height of the vessel, a location relatively remote from the bottom region of the vessel, where separated water collects, and from the fuel outlet (36 or 115) located near the top of the vessel.
- This midpoint fuel entry avoids remixing incoming fuel with previously separated water while providing sufficient residence time to enable water to settle out before the fuel passes into the outlet.
- Both embodiments likewise find the internal heating liquid conduit (22, 109) extending through the chamber from its top to bottom (conduit 22, FIG. 1) or at least into the bottom region (conduit 109, FIG. 3) where settled out water collects.
- the amount of heat supplied to the fuel by the heating liquid may be sufficient to melt or prevent the formation of individual ice crystals in the fuel, but insufficient to melt a body of ice which might be created by freezing of settled out water collected at the bottom of the vessel where it contacts the vessel housing which is essentially at outside ambient temperature.
- By routing the heating conduit through the bottom region of the vessel where the separated water is collected freezing of this collected water is prevented.
- By locating the filter (FIGS. 2-5) at the top of the unit rising heat from the lower portions of the unit assists the heating fuel in keeping the filter from freezing up. .Iaddend.
- the fuel processor apparatus of the invention functions in a manner related more closely to a chemical or petro-chemical device rather than a mechanical device. Certain highly advantageous considerations in accordance with the invention are as follows:
- the specific heat of fuel oil is approximately one third that of water.
- the specific gravity of fuel oil is approximately 80% of the specific gravity of water.
- the coefficient of expansion differential between diesel fuel and water is so significantly different that when the fuel is heated, the twin phenomena of specific heat and coefficient of expansion causes water entrapped or suspended in the fuel to quickly separate and fall out--where it can be collected and drained away.
- the surface tension of free water--once it is separated in the device of the invention --prevents water in the fuel processor from becoming resuspended in the fuel.
- Bacterial growth occurs in fuels but essentially only when water is present. Bacteria are a major threat to fuel filters due to their clogging action.
- Bacteria have demonstrated their ability to "wick" themselves up around fuel filters to permit their propagation on filter elements--thus rapidly clogging filters and causing engines and vehicle downtime and repair costs. Water in the fuel can also result in the formation of sulfuric acid which is harmful to engine accessories and operation.
- the device of the present invention through its action of removing water from the fuel acts to alleviate the problems of bacteria formation and sulfuric acid formation.
- the fuel processor device of this invention effectively dewaters fuel, removing over 99.7% of all suspended water--including that formed through the deterioration of the hydrocarbon molecule, and oxidation by the free oxygen in the atmosphere.
- Ice crystals form in fuel during cold weather [+32° or lower] when molecules of water are present in fuels.
- the specific gravity of ice is very near that of fuel and permits ice to flow with the fuel to the filters. When this occurs, ice crystals can completely clog or seriously reduce fuel flow to the engine.
- the specific heat value for ice is 0.505 [or approximately 1/2 that of water]; ice crystals melt quickly in the fuel processor apparatus of this invention. The newly formed liquid water, being much colder than the fuel and consequently much heavier, immediately falls to the bottom of the fuel processor where it can be drained away.
- Prevention of paraffin formations when ambient temperatures may drop below the cloud point of the fuel is accomplished by the fuel processor of the invention. In particular the greater weight of the molecules of paraffins and naphthenes are maintained in their liquid state.
- Fuel oil especially diesel fuel, shrinks when cooled. Fuel injectors operate by displacing a specific volume, therefore the heat potential of diesel fuel on a volume basis changes according to temperature.
- the fuel processor of this invention aids in improving fuel economy in diesel powered equipment in cold weather by restoring the diesel fuel molecule to a temperature consistent with factory engine calibrations and settings.
