Abstract
The invention discloses a kind of pressure increasing method by steam jet that is applied to all kinds of internal-combustion engines.Utilize heat energy vaporize water in heat exchanger of internal-combustion engine combustion gas, produce high-pressure water vapor.High-pressure water vapor is through the injection of convergent-divergent type nozzle, and air or inflammable mixture in injection and the compression internal combustion engine intake duct are realized supercharging.
The present invention can carry out pretreatment to air or flammable machine mixed gas except that realizing supercharging of internal combustion engine, reduce the discharging of harmful substance.When being applied to petrol engine and gas engine, also can improve the capability of antidetonance of motor.
Description
The present invention proposes a kind of new supercharging of internal combustion engine method-steam-sprayed supercharging, be applicable to all kinds of internal-combustion engines.
Task of the present invention is that vapor pump technology and steam generator technology are applied to internal-combustion engine technology, reaches supercharging, improves purposes such as exhaust quality and raising internal-combustion engine antiknock quality.
The various boosting methods of existing internal-combustion engine mostly are to utilize the kinetic energy of internal-combustion engine combustion gas or driven by bent axle to realize supercharging.The present invention utilizes the heat energy of internal-combustion engine combustion gas, and vaporize water in heat exchanger produces high-pressure water vapor.High-pressure water vapor is through the injection of convergent-divergent type nozzle, and the air or the inflammable mixture in injection and compress inlet air road are realized supercharging of internal combustion engine.
The existing method of improving the internal-combustion engine hazardous emission is a lot, and is single with regard to air being carried out pretreatment, internal combustion engine inlet water spray, the water spray steam simple way of can yet be regarded as.When injection flow rate equals amount of fuel, HO
XThe discharging of+CH reduces half approximately.Directly spray water, the cylinder corrosive wear increases, ponding pollution lubricating oil in the oil sump, the output power of minimizing internal-combustion engine.Change water spray steam into, then can not produce the problems referred to above.Working medium of the present invention is a high-pressure water vapor, and the water vapor of finishing after the pressurization enters cylinder, is equivalent to internal-combustion engine and sprays into water vapor.
When using separately boosting method of the present invention, consume mechanical work hardly, and the exhaust back pressure of increasing combustion engine not.If when being used for diesel engine, can with exhaust gas turbine formula or the compound use of wave pressure supercharger, constitute new combined type pressurization system.When the petrol engine application is of the present invention, can improve the quality of combustible gas, reduce the discharging of harmful substance.Water vapor can improve the capability of antidetonance of motor as a kind of antiknock agent.
Gas engine and other internal-combustion engine also can adopt the present invention.
Below with reference to accompanying drawing the present invention is described further.
With reference to accompanying drawing, softened water is through water pump (4).Enter heat exchanger (2).Heat exchanger can be general heat exchanger, also can be the heat exchanger with the silencing apparatus combination.The high-pressure water vapor that produces in heat exchanger (2) enters convergent-divergent type nozzle (5) after modulating valve (6) pressure regulation.Nozzle (5) is formed vapor pump with convergent-divergent shape intake duct (3).Modulating valve (6) keeps interlock with the amount of fuel controlling mechanism, to adapt to the various working condition requirements of internal-combustion engine.Through the high velocity vapor stream that nozzle (5) sprays, air or inflammable mixture in injection and compress inlet air road (3).The high-temp waste gas of air outlet flue (1) enters heat exchanger (2), the wherein softened water of vaporizing.
Claims (1)
- A kind of engine exhaust gas waste heat that utilizes produces high-pressure water vapor, through the injection of convergent-divergent type nozzle, and air or inflammable mixture in injection and the compression internal combustion engine intake duct, the method for realization supercharging.Jetting steam caused with mixed by the air of injection or inflammable mixture, together enter internal combustion engine circulation.
