Embodiment
The invention will be further described below in conjunction with drawings and Examples.
This internal-combustion engine improves on the basis of existing internal-combustion engine, becomes three cylinders of in-line arrangement by single combustion gas cylinder 28 and constitutes, be i.e. combustion gas cylinder 27, high pressure air cylinder 26 and pressurized gas cylinder 28.By the carrying out of four strokes, cylinder wall and the remaining heat major part of combustion gas can be recycled.
1. suction stroke: combustion gas acting piston 11 moves downward, and intake valve 2 is opened, and sucks air by suction port 1.Meanwhile, the high pressure air acting piston 14 that links to each other with combustion gas acting piston 11 also moves downward simultaneously, high pressure admission valve 8 is opened, suck the high-pressure air of high-pressure gas pipe 7, high-pressure air absorbs the casing wall of combustion gas cylinder 27 and the heat of burning hot gas outlet pipe, expand and do work, promote high pressure air acting piston 14 and move downward acting.The top two-piston transmits by piston rod 15 and bent axle 18 when moving downward, and displacer 20 moves upward, and enters into expiratory phase, and the one-way valve 23 of calming the anger is closed, and breather check valve 25 is opened.Move to lower dead center, two suction valves cut out, and begin to enter compression stroke.
2. compression stroke: combustion gas acting piston 11 moves upward, and intake valve 2 and exhaust valve 3 are closed.Meanwhile, high pressure admission valve 8 cuts out, and outlet valve 6 is opened, and the high pressure air acting piston 14 that links to each other with combustion gas acting piston 11 also moves upward simultaneously, and the waste gas that high-pressure air expands after doing work is discharged by outlet valve 6.Top two cylinders are when moving upward, and by piston rod 15, displacer 20 moves downward, and enters into the stage of calming the anger, and the one-way valve 23 of calming the anger is opened, and breather check valve 25 is closed.Air is pressed in the high-pressure gas pipe 7 by high-pressure pipe 24.
Here, high-pressure gas pipe 7 is formed by connecting side by side by many metals, and its total cavity volume is v=n π r
2L, r are high-pressure gas pipe cavity inner wall radiuses, and l is a high-pressure gas pipe length overall; The total amount of calming the anger V=π R
2L,, R is the displacer radius here, L is the displacer stroke.So pneumatics is than being ε=V/v 〉=4, energy recovery efficient is directly proportional with the pneumatics ratio.Because the high-pressure gas tube wall is thicker, voltage endurance capability is stronger, can prevent gas leakage; Be formed by connecting side by side by many metals, can in time dispel the heat, the heat that pressurized air is sent in time leaves, and is lower with the temperature that guarantees high pressure air, is convenient to heat absorption expansion acting.
3. expansion stroke: move to top dead center, two air intake-exhaust doors are closed, and fuel gas buring enters expansion stroke.Combustion gas acting piston 11 moves downward, and combustion gas is expanded and done work.Meanwhile, the high pressure air acting piston 14 that links to each other with combustion gas acting piston 11 also moves downward simultaneously, high pressure admission valve 8 is opened, suck high-pressure air, high-pressure air absorbs the heat of cylinder wall and hot gas outlet pipe, expand and do work, promote high pressure air acting piston 14 and move downward acting, two pistons in top are all in acting like this.The top two-piston is when moving downward, and by piston rod 15, displacer 20 moves upward, and enters into expiratory phase, and the one-way valve 23 of calming the anger is closed, and breather check valve opens 25.Move to lower dead center, two suction valves cut out, and begin to enter exhaust stroke.
4. exhaust stroke: combustion gas acting piston 11 moves upward, and intake valve 2 is closed, and exhaust valve 3 is opened.In exhaust fitting 5 entered into spiral hot gas gas storing pipe 10, the extreme temperatures of combustion gas this moment made the extreme temperatures of spiral hot gas gas storing pipe 10 outer walls of metal to hot gas after the burning by relief opening 4, for the acting of expanding of high pressure cold next time ready.Meanwhile, high pressure admission valve 8 cuts out, and outlet valve 6 is opened, and the high pressure air acting piston 14 that links to each other with combustion gas acting piston 11 also moves upward simultaneously, and the waste gas that high-pressure air expands after doing work is discharged by outlet valve 6.Top two cylinders are when moving upward, and by piston rod 15, displacer 20 moves downward, and enters into the stage of calming the anger, and the one-way valve 23 of calming the anger is opened, and breather check valve 25 is closed.Air is pressed in the high-pressure gas pipe 7 by high-pressure pipe 24, adopts the internal-combustion engine main shaft directly to drive 29 pairs of high-pressure gas pipes of fan and carries out forced air cooling.
Above-mentioned is exactly the process of four strokes.Cylinder wall and the remaining heat major part of combustion gas can be recycled by such mode.Although moving downward, displacer 20 wants consumed energy, the heat that pressurized air sends will leave as early as possible, adopt radiating fin 21 and high-pressure gas pipe 7 dispels the heat and 29 pairs of high-pressure gas pipes of fan carry out forced air cooling, become high pressure cold, but by theoretical estimation, the energy that high pressure cold heat absorption acting is reclaimed is much higher than displacer 20 and moves downward the energy that is consumed, and the thermal efficiency of internal-combustion engine can improve 30%.
