HYDROUS-BIOETHANOL-FUEL FEEDING ro
DEVICE FOR SPARK-IGNITION ENGINE =
Field of Invention 5
This invention relates to a fuel feeding device that enables hydrous a bioethanol (95% alcohol) fuel to be used for spark-ignition engine in either pure or blended form as replacement for conventional gasoline fuel. By = retrofitting the engine making the feeding of fuel by-pass the fuel tank and the carburetor, hydrous bioethanol can now be used as fuel in spark-ignition engines in lieu of gasoline. i
We are aware of the pressing need for alternative fuel to run spark- ignition engines commonly used by farmers in their rice farming in order to mitigate the increasing cost of rice production brought about by diminishing supply of crude oil. Hydrous bioethanol, which can be produced from the farm. either from nipa sap, sugar molasses, sweet sorghum, etc, is a good alternative for conventional gasoline fuel commonly used by farmers in fuelling their agricultural machines. However, the direct use of hydrous 1 bioethanol as fuel for spark-ignition engines poses lots of problems especially on corrosion of engine parts, particularly fuel tank and carburetor.
Spark-ignition engines utilize fuel which is entirely gasoline. With the
Biofuel Act of 2008, the use of anhydrous bioethanol (99.9% alcohol) blended
Page 1 of 10 :
with 10% gasoline is mandated and is being implemented. This type of fuel - (i.e. anhydrous bioethanol blended with gasoline), however, requires flexi-fuel engines in which the fuel tank, fuel line, and carburetor are designed to suit i the ‘use of gasoline blended with alcohol without damaging these engine parts. Unfortunately, in agricultural farming scenario, there are still lots of . conventional engines commonly used by farmers in powering their agricultural = machines. With the declining supply of imported crude oil, the cost of conventional gasoline fuel is continuously rising causing farmers to hardly utilize their engines. This problem is addressed by retrofitting the spark- 5 ignition engines making them adaptable to use farm fuel resources. By & providing a fuel feeding device, spark-ignition engines can now be ran with hydrous bioethanol that farmers can use to power their agricultural machines and equipment.
Hydrous bioethanol, which can be produced from discarded resources in the farm, can be used as fuel for conventional engines with the use of a special device (i.e. the hydrous-bioethanol-fuel feeding device). Feeding hydrous bioethanol to conventional spark-ignition engines by-passing the fuel tank and carburetor makes possible the use of alcohol as fuel without damaging engine parts. Farmers can now use either gasoline or alternately bioethanol in powering their agricultural machines without changing engine parts and setting. Since the Philippines is located in the tropical region, this warrants the use of hydrous bioethanol as fuel to the engine or blended with gasoline at a certain mixture. In tropical region where ambient temperature is relatively high, hydrous bioethanol is miscible with gasoline.

The object of this invention is to be able to run conventional spark- - ignition engines used by farmers in powering their agricultural machines and =O equipment with hydrous bioethanol as fuel either in pure or blended form. "
Another object of this invention is to be able to feed the engine with hydrous : bioethanol! fuel without allowing it to pass through the existing fuel tank and = carburetor, thus eliminating corrosion problem on engine parts which is = commonly encountered when engines are fueled with alcohol. This invention 1 is entirely different from the inventions described in US Patent Office . ] numbers: 2,421,580; 2589,946; and 2,298,563 for all these inventions use z conventional gasoline fuel and allow the fuel to pass through the carburetor, Bh fuel tank, and line of the engine.
The invention described herein is a device that is coupled to a conventional spark-ignition engine making it adaptable to use hydrous bioethanol as fuel either in pure or blended form.
The objectives of this invention are to: 1. make spark-ignition engines be fueled with hydrous bioethanol by feeding the fuel without passing through the existing fuel tank and carburetor thus eliminating corrosion problems on metal parts: and 2. run the fuel feeding device without the need for moving parts and
Just depending on the suction ability of the piston during operation thus making it more efficient and longer ie.

The present ‘invention will be fully understood from the detailed “ description given here below and from the accompanying drawings of the ~ preferred embodiment of the invention. It should not be taken to be limitative - to the invention but are for explanation and understanding only. -
In the drawings: &
FIG. 1 is the pictorial view of how the hydrous-bioethanol-fuel feeding o device is installed to the spark-ignition engine showing the two major oT assemblies namely, the fuel tank and the fuel injector; -
FIG. 2 is the cut away view of the hydrous-bioethanol-fuel tank assembly showing the location of the cover, casing, fuel outlet, and the drain pipe; and :
FIG. 3 is the cut away view of the fuel injector assembly showing the spray nozzle, air inlet hole, and fuel feeder.
Referring now again to the drawings, the invention which is a fuel- feeding device comprises of the following major components: Fuel Tank (1) ] and Fuel Injector (2). J 1. Fuel Tank Assembly
The fuel tank assembly (1) serves as container for hydrous bioethanol. It is made of stainless-steel cylinder (1a) serving as tank with mouth (1b) at the top to receive the fuel. The mouth (1b) has an . Page 4 of 10 i opening provided with a lid (1c) to keep foreign matters from entering - the tank. It has a small hole at the lid (1c) to equalize the pressure with N the surrounding during operation. At the lower end at one side is an . outlet pipe (1d) to féed hydrous bioethanol fuel into the fuel injector assembly (2). The outlet pipe (1d) is equipped with a ball valve to turn .
ON and OFF the feeding of fuel that extends through a flexible pipe wo (1e). The tank is also provided with a drain pipe (1f) with removable : cap to facilitate cleaning. = 2. Fuel Injector Assembly o
This assembly consists of spray nozzle (2a), air inlet hole (2d), and fuel feeder (2). It can be directly installed between the carburetor and the intake manifold to effectively feed pure hydrous bioethanol (i.e. 80% to 95%) or blended mixture (10:90 up to 90:10) with gasoline into the engine.
The spray nozzle (2a) serves the purpose of delivering the fuel- and-air mixture into the intake manifold of the engine for subsequent combustion. It consists of a duct with flanges (2b) at both ends with which it is attached to the carburetor at one end and to the intake manifold at the other end using bolts and nuts. A minute hole (2c) having a size of a hair line is drilled perpendicularly into the middle of the duct where fuel-and-air mixture is atomized and subsequently I enters the intake manifold of the engine.
The air-inlet hole (2d) allows controlled-flow of ambient air into the device. It is drilled into the periphery of the cylindrical casing (2e). i
Page 5 of 10
The casing seats perpendicularly on top of the spray nozzle (2a) oo : covering the nozzle opening. .
The fuel feeder (2f) is made of a screw-type control feeder with = a conical-shaped pin (2g) at the end serving as feeder and with a knob (2h) at the opposite end as control handle. All components are . enclosed by a solid metal-alioy casing (2i) to set the screw feeder and - direct the flow of fuel in the system. The fuel feeder (2f) is seated at ~ the upper part of the air-inlet hole (2d) in perpendicular position with - respect to the air-inlet hole (2d). Hydrous bioethanol fuel enters > through the inlet pipe (2j) that is located on the upper portion of the = ] feeder and leaves at the opposite end through a hole (2k) that is controlled by a pin.
