Description
Technical field
The present invention relates to utilize in the waste gas compression can engine system, comprising: the pressurized gas recovering device, a kind of pressurized gas converted to device, firing unit and the motor of another kind of pressurized gas.
Background technique
The energy conversion efficiency of reciprocating engine is very low, and most of energy is deflated have been taken away, if can reclaim this part energy, it is become power, will improve the energy conversion efficiency of motor greatly., power consumption maximum motor car engine the widest to use is example, and the energy of losing accounts for the 30-40% of total energy greatly, if can reclaim 10% energy, energy-conservation effect is with considerable.Utilize the technology of tail gas that turbocharging technology is arranged now, it is the pressurized gas that utilize cylinder to discharge, promoting turbine increases the air inflow of motor, to increase the method for compression ratio, make the combustion regime that reaches desirable in the cylinder, can improve the output power of motor, but, little to the energy conversion efficiency contribution that improves motor.Another approach that improves the engine power conversion efficiency is, work hard in the burning link, general employing is adjusted compression ratio, is adjusted and realize peak efficiency burning and optimum discharge period of combustion, development trend along with the various energy resources utilization, can only use the motor of the single energy to be challenged, thereby the setting of independent combustion chamber appearred, (as, application number: 97100644.X " the periodic duty method of internal-combustion engine and implement the device of this method ".) seek best combustion and optimum discharge under the different energy sources condition.Its basic principle is that the pressurized air that cylinder produces is sent into the firing chamber, through after lighting, opens the firing chamber switch in due course, promotes the cylinder acting.If in the design proposal of independent combustion chamber, do not consider the storage or the buffering of pressurized gas, along with the variation of fuel variations or output power, must produce the pressurized gas surplus, be discharged from, cause energy dissipation, or pressurized air and fuel ratio are undesirable, the phenomenon of firing effect difference.
Can the energy that motor exhaust is discharged be recovered and utilize that?
With modal cylinder engine is example.After pressurized gas in the cylinder is lighted, gas expansion for doing work, piston moves down, consume the energy that a part is brought because of gas volume increase after the detonation, when piston move to also do not open near lower dead center, outlet valve before, remain certain high pressure in the cylinder, open outlet valve after the cylinder acting, the pressurized gas physical efficiency explosive decompression in the cylinder enters atmosphere.From opening outlet valve, before motion in the other direction,, also can not reduce the outputting power of motor as long as just can not bring resistance to the pressurized gas discharge to motor to piston.Also we can say, the process of cylinder exhaust is the decompression process in the cylinder of cylinder acting back, in this course, cylinder does not provide power for motor, energy in the cylinder is released in vain, if the process of exhaust is divided into initial stage high pressure and later stage low pressure two-part, under the situation that does not influence the cylinder exhaust, reclaiming this part energy just becomes possibility.

The air compressor of high compression ratio more if desired can use the transducing machine of four sided rotor or five jiaos of rotors.Also can adopt multipole compressed format, or press the method raising compression ratio of several angle subtractive combination with a plurality of transducing machines.
The 3rd, firing unit improves the combustion efficiency of fuel.In firing unit, according to the characteristic of use fuel, the information of utilizing the pressure transducer of controller by the air gas holder to provide by selecting the air inflow of Air Valve Control firing chamber, makes various fuel can both reach optimal combustion state.High pressure tank has the effect of buffering, has eliminated the restriction of motor to compression ratio.
The 4th, engine device doubles mechanical efficiency.Utilize waste gas to produce pressurized air, removed the link of calming the anger of motor, mechanical efficiency doubles, the motor of the compression of the recovery of four cylinders just energy engine system, be equivalent to the power of the available engine system generation of eight cylinders, also reduce sub-cost of material and processing cost.
When using as motor car engine, only with the output of a Flow valve control power, cancelled clutch, car is stopped paying out motivation and is stopped, the interior energy of still high pressure gas holder that uses when starting once more, and whether work with the firing chamber does not have direct relation.There is not gas to discharge during parking.
The 5th, the pressure recovery engine system can be used various energy resources.1, uses various fuel, be not subjected to the restriction of engine performance.2, use the pressurized gas in the gas holder to generate electricity: the pressure recovery engine system, can take greater than making pressurized air at the energy that reclaims, the dump energy of generation can be done work by motor, substitutes motor.3, directly use the interior pressurized gas of gas holder: directly promote engine running with the air pressure in the waste gas gas holder.4, the pressurized gas that uses various transformation of energy to get.Such as, wind energy, electric energy, solar energy etc.
