The engineering process of motor: in the drawings, high energy gas is stored in the gas cylinder 19, opens gas cylinder non-return valve 18, enters engine inlets 14 after 16 throttlings of high energy gas process throttle, by throttle 16 control gaseous flows.By the bent axle in the actuating motor drive crankcase 1, make piston 10 move to the top dead center of cylinder, when rising, drain tap 9 on the piston 10 is collided with the last fore-set dish 12 on the cylinder, causes drain tap 9 to be made the location bead 23 on the drain tap that drain tap 9 is controlled at closed condition by collision when top dead center.Meanwhile, fore-set 10 on the piston ends balloon valve 13 with intake duct and backs down, high energy gas just flows to rapidly in the cylinder 8 of motor, when piston 10 when lower dead center is moved, intake duct end balloon valve 13 because be subjected to the elastic force of spring 15 and gravity of self and intake duct 14 in the pressure of high energy gas to make that intake duct ends balloon valve 13 closed tightly with the suction port of cylinder.High energy gas expands in cylinder 8 and promotes piston 10 and moves to lower dead center, when piston 10 moves in the process of lower dead center, drain tap 9 on the piston 10 just makes drain tap 9 open when final piston 10 moves to lower dead center owing to bump with following fore-set dish 6 gradually, location bead 22 in the drain tap 9 effectively is controlled at open mode with drain tap, and the gas that acting is finished in the cylinder just is discharged to the external world by the outlet pipe on the upper crankcase 45.In the movement process of piston 10, connecting rod 7 promotes the bent axle high speed rotating, and the counterweight 2 on the bent axle drives piston 10 to the top dead center motion by its own inertial power, and motor is just finished a circulation like this, and motion makes motor continue the output shaft work and so forth.
The speed governing of motor: control the purpose that the pressure loss of high energy gas before and after the throttling reaches speed governing by throttle 16.Control high energy gas volume and the pressure that enters in the intake duct 14 by the size that throttle 16 is opened.The valve port that throttle 16 is opened is big, the pressure energy that flows into the high energy gas in the intake duct 14 so lose relative open valve young to lose less.The expansion work of high energy gas that enters cylinder 8 like this is just big, and the motion of piston 10 is accelerated, and the rotational speed of bent axle is accelerated, and promptly the inertial force of counter weight 2 is just big, and the shaft work of output is bigger, and promptly the thrust of motor is just big, speeds up; On the contrary, the valve port that throttle (16) is opened is little, and valve port is opened big relatively, and its pressure energy loss is bigger, cause the high energy gas pressure that enters cylinder to reduce, the expansion work of gas just reduces, and the kinetic energy of piston 10 reduces, and the rotational speed of bent axle slows down, the inertial force that is counter weight 2 reduces, the shaft work of output reduces, and promptly the thrust of motor descends, and speed slows down; When the throttle 16 opening state maximums of motor, the energy loss minimum of throttling, promptly the thrust of motor is maximum at this moment, and is promptly fastest.
The starting of motor and the coordination of parts control: open the non-return valve 18 on the gas cylinder 19 earlier, control throttle 16 openings of sizes again, make high energy gas enter engine inlets 14, connect the power supply of actuating motor then, output shaft by actuating motor is connected with the starting shaft of bent axle one end of motor, make the bent axle of motor obtain an initial velocity by actuating motor, promptly the counterweight on the bent axle 2 has obtained initial velocity.Inertial force by counter weight 2 makes piston 10 motions move to top dead center, fore-set on the piston 10 backs down the air-stopping valve door bead 13 in the intake duct 14, because cylinder 8 internal pressures are lower, end the moment that balloon valve 13 is opened, high energy gas flows in the cylinder 8 rapidly, high energy gas enters cylinder 8 backs and expands rapidly, promote piston 10 to the lower dead center motion, this moment, air-stopping valve door bead 13 was because self gravitation, the elastic force of spring 15 and the pressure of high energy gas cause it that valve is closed tightly.High energy gas just expands in individual airtight volume and does work.Piston 10 is subjected to the promotion of expansion work, drives crankshaft rotating, utilizes the inertial force drive piston 10 of counter weight 2 to move to top dead center.Motor is just finished a circulation like this, smoothly starting.In the process of engine start, what motor served as is the effect of actuating motor, and electricity of accumulator is transformed into the shaft work of motor output shaft, drives the bent axle motion of motor.In the working procedure of motor, actuating motor is the effect of serving as generator, and the part shaft work of bent axle is transformed into electric energy, is stored in the storage battery, for starting next time of motor provides electric energy, i.e. two of actuating motor effects: starting and generating.Compression ring 11 on the piston 10 mainly is the tightness that guarantees between cylinder inner wall and the piston, reduces the leakage of high energy gas.For guaranteeing the acting ability of high energy gas.
Motor is to do work by high energy gas, so should reduce delivery line length as much as possible, reduce the energy loss (as: loss that the pipe interior out-of-flatness causes etc.) in the course of conveying, on the mounting structure of motor and gas cylinder, also done further design, adopt gas cylinder 19 direct schemes of directly docking, on lower crankcase 1, be provided with gas cylinder 19 mounting base with the throttle 16 of motor.By the method for thickening cylinder outer wall, a gas cylinder chuck seat 20 has been installed on outer wall on the one side in cylinder 8 outsides, gas cylinder 19 usefulness chucks 21 encase, and are connected with bolt between chuck 21 and the chuck seat 20, and chuck 21 can center on bolt and rotate on chuck seat 20.Two chuck 21 usefulness chuck fastenings, thus the stability of gas cylinder 19 on motor guaranteed.
The parking of motor: because actuating motor just transfers generator to and generates electricity after the motor proper functioning, want to stop, the throttle 16 on only need slowly killing engine does not have high energy gas to enter intake duct 14, motor does not have power source just can't do work, and promptly keeps vehicle stop state.Perhaps, can directly close non-return valve 18 on the gas cylinder 19, stop the high energy gas in the gas cylinder to flow out to reach the parking purpose according to motor mounting arrangements onboard.
The control of drain tap on the engine piston: the outlet valve 9 on the piston 10 is determined the switching position by the exhaust port and the location bead between the outlet valve 9 22 of piston 10.The dislocation by the hole on location bead 22 and the outlet valve 9 and the jam-packed power of the little spring 23 in the piston exhaust port realize the on off state of outlet valve 9.On a side of each exhaust port of cylinder, two apertures (four holes are arranged on each exhaust port) are arranged, little spring 23 is housed in the aperture, one end of location bead 22 is connecting little spring 23, three apertures are arranged on the outlet valve on the piston 9, when outlet valve 9 was in open mode, following two holes of bead 22 on outlet valve 9, two location positioned.When outlet valve 9 was in closed condition, bead 22 two holes on the outlet valve 9, two location positioned.The invariant position of two location beads 22 in the whole process, just the position of outlet valve 9 is in the changing of the relative positions up and down.When outlet valve 9 collided fore-set dish 12, outlet valve 9 was subjected to a downward impact force, forced outlet valve 9 to move downward, and caused the position of location bead 22 by following two holes on the outlet valve 22, changed the position of going to locate two holes.So effectively outlet valve 9 is firmly closed.When outlet valve 9 collided down fore-set dish 6, outlet valve 9 was subjected to an impact force that makes progress, and forced outlet valve 9 to move upward, and caused the position of location bead 22 by last two holes on the outlet valve 9, changed the position of going to locate following two holes.So effectively outlet valve 9 is opened, so that the gas that acting is finished is got rid of cylinder smoothly.
