The work cycle principle of reciprocating separable piston type three-stroke internal combustion engine of the present invention is as follows:
First stroke: expansion working stroke: when the work done of gas burning expansion, the expansion gas promotes three piston DL synchronizations, the waste vapour work doing pistons is at first closed exhaust hole in the waste vapour cylinder in descending, gas is compressed in the waste vapour cylinder, then piston shaft unidirectional admission opening in descending process enters the firing chamber by seal ring, expansion gas in the cylinder is dispensed into the waste vapour cylinder by unidirectional steam inlet valve, when the waste vapour cylinder equates substantially with cylinder pressure, one-way valve is closed under spring action automatically, it is descending that the waste vapour work doing pistons relies on coherence to continue, ear end face impacts the steam discharge shift fork and opens the steam discharge door, waste vapour major part in the cylinder is entered big vapour, when the waste vapour work doing pistons relies on coherence to arrive lower dead center, held by the lower dead center on the waste vapour casing wall, finish the work done expansion stroke.
Second stroke: sweep the vapour aspirating stroke:
The waste vapour work doing pistons comes downwards to lower dead center, held by the lower dead center on the waste vapour casing wall, inertial force stops suddenly, produce reaction force, add the interior most expansion gas of casing top half and entered big vapour, secondary piston front-end face pressure is eliminated, the waste vapour work doing pistons is subjected to waste vapour pressure in the waste vapour cylinder, work done rapidly, and it is up to drive secondary piston, because crank, connecting rod also has a segment distance, crank from lower dead center this moment, connecting rod continues be with back piston descending under the coherence effect, and the front and back piston one on the other, the pull of vacuum of Chan Shenging is from steam inlet inspiration capacity gas therebetween, and the secondary piston front-end face scans out cylinder with residual waste vapour in the cylinder gradually in up.Waste vapour cylinder steam-expelling port exposes in the waste vapour work doing pistons is up gradually, gets rid of waste vapour cylinder waste vapour.Waste vapour work doing pistons front-end face is closed the porthole shift fork by up the pushing of coherence, closes exhaust valve.Arrive at top dead center, held, and that piston cap continues under the coherence effect is up, separate, stopped by the guiding valve screw rod, thereby opened secondary piston aixal admission hole, finished and swept the vapour aspirating stroke with secondary piston by the vibration silencer packing ring.
The 3rd stroke, compression stroke: after back piston separates, crank, connecting rod is walked around lower dead center under the effect of coherence up, back piston is at first closed the admission opening on the cylinder wall in up, continue uply, and gas is pressed into the firing chamber by hole on the secondary piston or groove, connecting rod, when crank is walked around top dead center arrival ignition location, finish compression stroke, thereby finished a work cycle, be crank, connecting rod has rotated 360 °.Three pistons have respectively been finished one back and forth.
When motor quits work,, lift piston disconnector, the waste vapour work doing pistons is separated with the vibration silencer packing ring for the high temperature that prevents the waste vapour work doing pistons scorches the vibration silencer material.Can assemble backguy as required on the piston disconnector or drive link is handled.
The connecting rod of reciprocating separable piston type three-stroke internal combustion engine of the present invention, the institution of distributing gas, fuel supply system, cooling system, lubricating system can be matched in existing technique known according to different needs.During the crank-connecting rod counterrotating, only need corresponding adjustment igniting and join the vapour phase position.Also can between the corresponding waste vapour casing wall of garden, piston shaft epimere outside cylinder, assemble the reflex spring, the work done of cancellation waste vapour, reaction force after dependence reflex length of spring compressed or the elongation is finished and is swept the vapour aspirating stroke, can also worm gear or blade be installed at steam exhausting way, utilize the waste vapour of discharging to worm gear or blade work done, again by belt wheel or sprocket wheel, or gear or crank-connecting rod transmission, the drive piston shaft is up, finish and sweep the vapour aspirating stroke, its effect all is the same, fuel of the present invention can be gasoline, diesel oil, heavy oil, also coal vapour, day combustion vapour, oil system vapour, liquefaction vapour and other flammable gas or liquid when fuel of the present invention is diesel oil, only need to replace spark plug with high pressure fuel injector.
