Abstract

The innovation / invention relates to mechanics (in automotive technology) in the form of a fuel system for a Spark Ignition Internal Combustion engine. As far as the SIIC ( Spark Ignition Internal Combustion ) engine is concerned, the fuels (alternative fuels ) of higher ignition point ( mainly), higher specific heat, higher specific gravity, lesser volatility than petrol can not be used or can not be used at a better rate of combustion even though the compression ratio is increased. In case of the alternative fuel is used, it should be in the form of an atomised vapour having ' temperature increase' in between it's ignition point and self ignition point so that the in-charge behaves as a good thermodynamic medium for both compression and power strokes & the in-charge is combustible at a batter rate. Such type of fuel vapour will be a better one to drive a Spark Ignition Internal Combustion engine. (The produced innovation/invention has been done to a 4-Stroke Spark Ignition Internal Combustion engine.) The atomised vapor is obtained by a fuel vaporizer (the most innovative/inventive part) which has taken the place of main fuel outlet (nozzle) of a conventional carburetor, in the innovated/invented carburetion system. The fuel from the float chamber comes to the vaporizer through a fuel controlling valve and a solenoid valve, where the fuel is heated up beyond its boiling point and below the self ignition point. As soon as the heated fuel comes out of the vaporizer, it will become a fine atomized vapor (in the air available at the main venturi) having the quality of better combustion.

Claims

AMENDED CLAIMS
[received by the International Bureau on 11 March 2004 (11.03.04); original claims 1- 4, 9-10 and 16-17 cancelled; original claims 5-8, 18 and 19 amended ; original claims 11-15 unchanged; new claims 20-26 added (3 pages)]
5) The very same vapourizer employed in the innovated carburetor system(claimed in 20) as the fuel nozzle is providing cold starting and easy starting the (carburetor based spark ignition type internal combustion) engine from the alternative fuel used (kerosene /diesel / or other fuel) itself without using any other ' equipment/arrangement (to provide the same) ' in the carburetor system.
6)
6.1 ) This innovation/invention leads to even temperature rise of almost every molecule of fuel during compression of air-fuel mixture in the compression stroke.
6.2) By using this innovated fuel system, the combustion of most fuel molecules amidst molecules O2, completes at a highest possible compression ratio (just after top dead center of piston movement or close by) , (since flame travel time and combustion duration is now lessen)
7) This innovated fuel system helps to create more water vapour in the combustion evenly everywhere throughout the medium. This water vapour catches up the heat produced (and expands) so that the molecules of N2 is not heated up to extreme temperatures . Therefore this innovated fuel system also prevents producing oxides of nitrogen in the combustion, in carburetor based spark ignition internal combustion engine.
8) Using the innovated fuel system Kerosene leads Petrol in the properties (like engine torque, brake horse power, thermal efficiency, low fuel consumption, low exhaust emissions etc) which exhibit in an auto mobile spark ignition internal combustion engine(having carburetor type fuel system).
1 1 ) Wankel Rotary engine (Rotary combustion engine ) ' s in-take port can be fed by this fuel system (since the conventional carburetion can be replaced with the innovated/invented type of carburetion) and it can make use of this fuel system' s performance (to drive the engine from the alternative fuel etc.) .
12) A greater potential is to be used this vapourizer in the gas turbine (including the j et engine, turbo-prop etc) and enhanced the combustion. The fuel nozzles (by which the fuel is sprayed in to the burner and it is located close to the igniter) can be replaced with these vapourizers in order to have a better rate of combustion and easy ignition. Then there will be a better thermal efficiency and increases gasifing, for the fuel used which is gasoline, kerosene or oil.
13 ) The conventional methods of petrol heat treatment or complexity & power wastage on pressurizing the fuel to atomize, in "fuel inj ection systems " can directly be overcome by the innovated/invented fuel System' s simple, efficient heat treated fuel (petrol) atomization (by vapourization) with less electrical power. 14). Multiple "innovated fuel systems" (with synchronized controlling, that is throttle valves & chork valves.) can be used to feed a single in-take port so that there will be an electrical selection on the " accelerator-performance" . 15) Multiple "innovated fuel systems" (with synchronized controlling) can be used to feed each in-take port of each cylinder.
18) Depending on the rate of temperature of ' in-take air to this innovated carburetor system' , in-take air can also be heated up accordingly (by means of an electric heater element exposed to the air stream and 'temperature monitoring & controlling system'), before the air passes through venturi(where the air comes into contact with fuel molecules) and mixed up with fuel particles . 19) A simple pump(with small delivery pressure enough to overcome the resistance to the flow of fuel through the vapourizer) can be included in the carburetor system itself between the float(fuel) chamber(19 in the drawing) and fuel controlling valve(no 21 in the drawing) in the path of fuel flow. (Then the in-take suction is more available to draw more in-charge volume from the carburetor to the spark ignition internal combustion engine.) (Where in the arrangement, the said pump maintains the pressure to overcome the pressure produced in the expansion of fuel due to heat in side the vapourizer and controlling valve controls the release of fuel to the vapourizer)
20) This innovation/invention uses a special type of carburetor as the fuel system, in-which the fuel nozzle (or fuel j et) is an efficient electric vapourizer(to use alternative fuels like Kerosene/diesel/or other heavy fuel in spark ignition internal combustion engine) .
2 1 ) The said fuel nozzle (the vapourizer) in claim 20, acts as both main nozzle and idling nozzle (idling j et) in the innovated carburetor fuel system.
22) (Since the fuel heated up beyond the boiling point acquires a better flow rate of fuel), this innovated carburetor system does not need any accelerator pump, accelerating fuel nozzle or any accelerating system in the fuel system for sudden acceleration.
16 23) This innovated fuel system acts as enhancement of power delivery duration to non expansion duration in the period of working (power) stroke over the whole speed range- on the engine r.p.m. (since this innovated fuel system ensures that combustion of in- charge completes more earlier and allows more time for expansion in the working stroke.)
24) This innovated fuel system acts to ensure (reducing flame travel time and combustion duration) that combustion of most fuel molecules takes place in unison.
25) As combustion of fuel molecules taking place in unison (as claimed in 24) ), the work done (due to thermal energy) by 'molecules and atoms in the expansion medium' , also takes place in unison. Therefore by using this innovated fuel system it gets whole work done from 'molecules and atoms in the expansion medium' occur in unison.
26) The existing Spark Ignition Internal Combustion engines (the power sources) in auto-mobiles can be replaced with smaller Spark
Ignition Internal Combustion engines' having the innovated invented fuel system, to give the same power out.
