Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment and high pressure steam working medium type.
Internal and external combustion engine as shown in Figure 1, described in the invention comprises conventional engine structure (being the internal combustion assembly) and high pressure steam operation mechanism (external combustion assembly) two-part on the structure.The conventional engine part is example (but being not limited to this) with the diesel engine, mainly comprises on the structure: engine exhaust pipe 1, engine exhaust port 2, engine cylinder cover 3; Oil sprayer 4, engine intake valve 5, engine air inlet tube 6; Cylinder 7, piston 8, engine crankcase 12, engine link 14; Crank 15, the annexation of above-mentioned each parts and working principle are existing technology, are not described in detail in this.High pressure steam operation mechanism partly comprises: piston rod 9, steam exhaust-gas door 10, steam exhaust pipe 11; Slide block 13, steam generator 19, steam inlet duct 20; Cylinder sleeve and cylinder head steam tube 21; Steam inlet door 22, high pressure steam seal operation chamber 23, one-way valve 24 and water pump 16, water tank 17 and cooling liquid pipeline etc.
Wherein, be waste heat energy recycle device of the present invention with steam generator 19 with the device that relevant connecting pipeline constitutes.Steam generator 19 utilizes engine exhaust heat to produce steam, and cylinder sleeve and cylinder head jacket also produce steam and play the cooling action to cylinder sleeve and cylinder head simultaneously, and the high pressure steam that this two place produces is exactly the power that promotes the piston stroking upward acting.All take seal approach to prevent gas leakage on high pressure steam inlet and outlet door, piston rod and high pressure steam seal operation cavity 23 each surface of contact, (being in cylinder sleeve and the cylinder head steam tube 21) design one-way valve is with the control steam flow between the high pressure steam pipeline.
Further as shown in Figure 1; The working procedure of entire mechanism is following during the up pressurized gas of engine piston of the present invention: similar with conventional engine; Engine intake valve 5, exhaust valve 2 are closed during pressurized gas; The piston stroking upward pressurized gas; High pressure steam operation mechanism steam inlet door 22 when piston stroking upward of this programme design is simultaneously opened, and steam exhaust-gas door 10 is closed, and the high pressure steams in steam generator 19, cylinder sleeve and the cylinder head steam tube 21 get into high pressure steam seal operation cavity 23 fast, and (heat that needs of steam generator 19 is to provide through the high-temp combustion waste gas that engine exhaust port 2 is discharged here; The liquid water of pumping entering steam generator is vaporized under the heat effect that high-temp waste gas brings and is formed high pressure steam), high pressure steam produces thrust and promotes the piston stroking upward acting in piston 8 lower end surfaces; When piston 8 is prepared when descending near top dead center; Steam inlet door 22 is closed, and steam exhaust-gas door 10 is opened, and seal chamber 23 is connected with external pipe; Intracavity gas is discharged (entering water tank 17 through steam exhaust pipe 11) rapidly; Air pressure moment reduces, and piston is not produced descending resistance, and descent of piston externally does work through piston rod-slide-block mechanism drivening rod-bent axle, and (wherein piston rod 9 and slide block 13 are for being fixedly connected; Slide block 13 is connected with an end pin of connecting rod 14, and the other end of connecting rod 14 is connected with crank 15 pins); The high pressure steam acting is identical with compression stroke during the up exhaust of engine piston, and just this moment, engine intake valve 5 was closed, and exhaust valve 2 is opened, and high pressure steam produces upwards acting of thrust below piston, quicken the interior waste gas discharge of cylinder body.
The present invention is promptly on the basis of original engine operation principle, and high pressure steam intake valve 22 is opened when piston stroking upward, high pressure steam exhaust valve 10 cuts out, and high pressure steam promotes the piston stroking upward acting; High pressure steam intake valve 22 is closed during descent of piston, high pressure steam exhaust valve 10 opens; Seal chamber 23 is communicated with external pipe, and intracavity gas is discharged rapidly, air pressure moment reduction; Piston is not produced descending resistance, piston can externally do work under the gaseous-pressure effect.Promptly on the basis of available engine, add the thrust of external high pressure steam when piston stroking upward, make external combustion combination acting in the whole realization of motor.
High pressure steam of the present invention is produced by engine high-temperature exhaust air and high temperature cylinder cap, cylinder sleeve heating low-boiling point liquid, through promoting the piston stroking upward acting in the compression of motor during with exhaust stroke, realizes that engine exhaust heat recycles raising fuel energy utilization ratio; Receive the thrust of seal operation chamber inner high voltage steam during simultaneously owing to piston stroking upward, promptly, make more efficient operation of motor through the mode of internal-combustion engine and external-combustion engine combination acting; In addition, piston rod-slide-block mechanism of the present invention makes it with the upper and lower motion of piston, and link design is in the seal chamber lower end, when the slide block connecting rod Shi Buhui that swings that moves up and down receives the restriction in seal chamber space.
