Definitions
- the present invention relates to an apparatus for filtering fuel used in internal combustion engines. More particularly, the present invention relates to apparatus that separates air and water contaminants from the fuel. Background Art
- the diesel engine is an internal combustion engine that differs from the gasoline engine principally in that it relies on heat generated by compressing air in a cylinder to ignite the fuel, rather than on an electric spark. To generate the required heat, the diesel must produce higher compression than the gasoline engine, thereby making it bulkier, heavier and more expensive.
- the diesel engine also operates more cheaply, on less highly refined fuel, which can give it an advantage in transportation and construction-equipment applications such as locomotives, trucks, tractors, buses, bulldozers, graters, and other heavy-duty machines, and in marine propulsion.
- SHEET never exceeds the pressure obtained by the compression of the air.
- the piston continues to move away from the cylinder head in its downward or expansion stroke (power) ; (4) the burned fuel is forced from the cylinder by upward motion of the piston (exhaust) .
- Diesel took out patents on an engine to operate on the cycle just described. Either powdered coal or liquid petroleum would be used as fuel. Diesel planned to use compressed air to introduce the coal dust into the engine cylinder but found it difficult to control the rate of injection so that the maximum pressure in the cylinder after ignition would not exceed a safe limit. After the experimental engine was wrecked by an explosion in the cylinder, Diesel gave up the idea of using the coal dust and devoted his efforts to the use of liquid petroleum.
- the first commercial engine built on Diesel's patents was installed in St. Louis, Missouri by brewer, Adolphus Busch, who had seen one on display at an exposition in Kunststoff and had purchased a license from Diesel for the manufacture and sale of the engine in the United States and Canada.
- the engine operated successfully for many years and was the forerunner of the Busch- Sulzer engine that powered many submarines in the U.S. Navy in World War I.
- the diesel engine was economical in the use of fuel and it proved itself reliable under wartime conditions. Diesel fuel, less volatile than gasoline, was more easily stored and handled.
- a diesel engine is started by driving it from some external power source until conditions have been established under which the engine can be run under its own power. The most positive starting method is by admitting air at 250 to 350 p.s.i.
- the first was a volatile distillate recommended for high-speed engines with frequent and wide variations in load and speeds; the second, a distillate for high-speed engines in services with high loads and uniform speeds; and the third, a fuel for low- and medium-speed engines in services with sustained
- Fuels with a high carbon residue can be handled best by engines of low-speed rotation. The same applies to those with
- the octane number which defines the ignition quality of a fuel, is ascertained by adjusting a mixture of octane and alpha-methyl-naphthalene until it has the same ignition quality as the fuel being tested. The percentage of octane in this mixture is then the octane number of the fuel
- the owner of the vehicle will be unlikely to take the necessary steps to remove the accumulation of water from the fuel chamber.
- the diesel vehicle will be disabled 115 because of the accumulation of water in the fuel chamber. Under these circumstances, the owner of the vehicle will incur large maintenance fees and will have a diesel vehicle that is inoperable until proper repair is implemented.
- U.S. patent number 2,503,566 issued to A.S.B. Scott on April 11, 1950 teaches a filter with a mechanical valve that can drain water from a tank. This allows the sump of a filter to be cleaned and flushed without dismantling the filter.
- U.S. patent number 4,224,157 issued September 23, 1980 to K.K. Jain teaches a particulate to filter.
- U.S. patent number 4,321,136 issued March 23, 1982 to . Matsui for a fuel filtering device teaches the use of sensors to heat fuel to prevent the build-up of wax.
- U.S. patent number 4,437,986 issued on March 20, 1984 to Charles Hutchins, et. al. teaches a separating device for separating water from a liquid mixture which uses an annular coalescing medium. This invention also teaches temperature control to prevent wax build-up and provides for a pressure 135 bypass to allow the liquid to bypass the filter after a set pressure across the filter element is reached.
- U.S. patent number 4,539,109 issued September 3, 1985 to L.L. Davis for drain system for fuel processor apparatus teaches the use of an automatic control means to control the separation 140 of water from fuel.
- Davis teaches a sensing means for detecting the presence for predetermined amount of water or other impurities and a electrically controlled drain means to maintain the water or other impurities below a predetermined level.
- Davis also teaches a heater means to prevent wax build-up.
- U.S. patent number 4,637,351 issued January 20, 1987 to B.J. Pakula for a system for removal of water from diesel fuel systems, teaches the use of a solenoid operated valve to allow the discharge of water from a gravity fuel separator.
- Another object of the present invention is to provide a fuel filter, separator and boost pump that reduces engine maintenance requirements.
- the present invention is a fuel filter and separator including a boost pump that comprises a chamber, a discharge valve, a fuel pump and a fuel filter.
- the discharge valve is 185 electrically operatable and is connected to an electronic control ifieans. These electronics are also connected to a water sensor in the lower part of the filter chamber.
- the fuel pump is connected to the fuel filter through check valves that allow fuel to flow through the pump when the pump is operating and allow 190 fuel to flow directly into the inlet of the filter when the pump is not operating.
- the discharge valve for the selective discharge of contaminant fluid from the chamber is connected to the bottom of the filter chamber.
- the fuel pump typically, is connected to the fuel line of the vehicle.
- the fuel pump is 195 connected to the fuel line through a check valve.
- the boost pump of the present invention is capable of generating a higher fluid pressure at its output than the pressure supplied to the boost pump fuel inlet by the fuel pump of the vehicle.
- its output 200 pressure overcomes the fuel pressure acting on a check valve which closes a fuel bypass line and causes fuel to flow through the boost pump into the fuel filter.
- the output of the boost pump is in fluid communication with the inlet of the fuel filter.
- the fuel filter is a commercially 205 available filter that uses a coalescar media, such a the Fram 5000 Series. These filters have an internal filter element housed within a chamber.
- the chamber which has a threaded drain hole at its bottom.
- a remotely actuated solenoid valve is attached to the drain opening of the 210 filter.
- a sensor that detects water level within the chamber is also inserted into the chamber through the drain plug opening. Both the water level sensor and the solenoid actuated valve are connected to electronic control means.
- the electronic control means allows: 1. the valve to be manually operated to dump the 215 water from the chamber; 2. allows the fuel boost pump to be operated manually to restart the diesel engine if air contaminant has gotten into the fuel line; and 3. allows the automatic operation of the solenoid dump valve when a predetermined level of water is detected in the filter chamber.
- Figure 1 is a block diagram showing the present invention within the fuel system of an internal combustion engine.
