Definitions
- the present invention relates to a reciprocating engine, particularly but not exclusively for self--propelled vehicles, of the type including at least one cylinder within which a piston is movable axially and which is provided with inlet and exhaust ports in which respective valve members are operable, an electrical circuit including a voltage source, a capacitive-discharge ignition system, and a distributor.
- This invention seeks to solve the problem of providing a reciprocating engine of the aforesaid type which has structural and functional characteristics similar to, and a performance comparable with, a reciprocating internal combustion engine without, however, requiring the combustion of petrol or similar combustible petroleum derivatives for its operation.
- vapour particularly steam
- a reciprocating engine of the type specified, characterised j in that it includes means for admitting a predetermined quantity of water, preferably in atomised form, to said at least one cylinder, and a generator of microwaves of a predetermined frequency in the range 5 to 10 GHz, having its outlet communicating with said at least one cylinder, the microwave generator being connected electrically to the electrical circuit and supplied for between 10 and 25 microseconds with a current of a power and voltage suitable for the emission of microwaves having said predetermined frequency.
- the microwave generator comprises a magnetron which is fixed to the said cylinder and encased by shielding material suitable for blocking possible emission of secondary radiation.
- the reciprocating engine of the present invention includes, to advantage, a forced ventilation system for cooling the magnetron.
- the moment at which the microwaves are emitted into the cylinder is of particular importance in achieving the required and desired vaporisation. It has been found that the best results are achieved when such an emission of microwaves occurs between 65° and 55° before the top dead centre position of the piston.
- the quantity of water which must be admitted to the cylinder to operate the reciprocating engine of this invention is substantially the same as that of the fuel (petrol) required for the operation of an internal combustion engine having the same functional and structural characteristics.
- the microwaves generated by the magnetron when pure water is admitted to the cylinder, it is preferable that the microwaves generated by the magnetron should have a frequency of the order of 9 GHz. Since it is desirable to ensure that the valve units in the inlet and exhaust ports are lubricated, a very small quantity of oil may be added to the water admitted to the cylinders (an oil/water ratio of, for example, 1/1000 to 1/100 is sufficient for this purpose). In this case, the microwaves generated by the magnetron preferably have a frequency f about 6 to 7 GHz.
- microwaves having a frequency of 5 to 7 GHz With microwaves having a frequency of 5 to 7 GHz, the rapid vaporisation of the water is ensured even when it has added to it small quantities of, for example, antifreeze and/or colorant pigments provided for fiscal reasons.
- each cylinder is provided with a microwave generator of the aforesaid type and the four microwave generators are connected in an entirely conventional manner to the distributor of the electrical circuit of the engine itself.
- a reciprocating steam engine according to this invention which may be defined as a reciprocating engine with internal vaporisation, offers the not inconsiderable advantage of discharging water into the environment as a liquid and/or vapour, thus eliminating any possibility of atmospheric pollution.
- a reciprocating steam engine comprises, in a simplistic form, a cylinder 1, within which is axially movable a piston 2 with a fluid-pressure seal, which is connected kinematically to a crankshaft 3 in a conventional manner.
- the cylinder 1 is provided conventionally with respective inlet and exhaust ports 4, 5 within each of which valves 6, 7 are operable.
- a microwave generator is fixed releasably to the head 1a of the cylinder 1 by conventional means.
- This generator 8 is able to generate and to emit microwaves with a frequency in the range 5 to 10 GHz, and is preferably constituted by a magnetron.
- model BLM-311 made by the VARIAN Company (USA) is particularly useful, and its known electrical characteristics are given below:
- the magnetron ' 8 has its outlet 8a facing into the cylinder 1 through an aperture 9a .
- the magnetron 8 is connected electrically to a conventional distributor 19 forming part of the electrical circuit of the engine.
- This circuit comprises essentially an electronic capacitive-discharge ignition system, schematically indicated 10, a dynamo 11, and a battery 12 of the type normally used in the electrical circuits of internal combustion engines.
- the dynamo 11 is is driven by the crankshaft 3 to which it is connected, as shown schematically, by means of a pulley 13, belt 14 and pulley 15.
- the electronic capacitive-discharge system 10 is of the type illustrated in Figure 1 of U.S. Patent No. 3,453,492 of 1st July, 1969 in the name GIANNI ABRAMO DOTTO.
- the electronic capacitive-discharge circuit 10 is provided with a capacitor having a capacitance of at least 10 mF.
- a casing, indicated 16 is fixed conventionally and releasably to the head la of the cylinder 1 to surround the magnetron 8.
- This casing 16 is made from a material suitable for shielding any possible secondary emission of ⁇ radiation from the magnetron.
- a forced ventilation unit cools the magnetron during operation of the reciprocating engine of the invention, while a liquid injector device, schematically indicated 18, may be provided to introduce a predetermined quantity of water, preferably in atomized form, to the cylinder 1 through the port 4, when it is desired to use such an injector device.
- a predetermined quantity of atomized water is drawn (or introduced by the injector 18) into the chamber formed between the piston and the cylinder head.
- This quantity of water is substantially equal to the quantity of fuel (petrol) which would be drawn into a cylinder of a conventional internal combustion engine with the same structural and functional characteristics.
- the magnetron 8 suitably excited by the electrical circuit described above, emits a beam of microwaves of predetermined frequency into the cylinder 1.
- the magnetron 8 has an internal filament which is continuously energised by the battery or the dynamo. Only when it is necessary (65 0 to 55° before the top dead centre position in the compression stroke) is the magnetron fed with current at a voltage suitable for the emission of microwaves of the desired predetermined frequency.
- microwaves rapidly (within 10-25 microseconds) cause the vaporisation of the water which has previously been drawn or injected into the cylinder.
- the rate at which the water changes its state is also affected by the fact that the volume of the chamber defined between the piston and the upper head of the cylinder gradually diminishes during the compression stroke so that the interaction of the microwaves with the water molecules is gradually enhanced, with a result comparable to a terminal microwave "boosting" effect.
- this discharge largely comprises water in the vapour and/or liquid states.
- microwaves having a frequency of 9 GHz in order to achieve a vaporisation time of the order of 12 microseconds.
- microwaves with a frequency of the order of 5-7 GHz.
