The definition in direction: the invention enter out with piston cavity to be parts, to enter into for entering in it, depart from and be considered as out.
Stretch into and contract have two kinds of forms:
1, make expansion chamber stereomutation, realize compression when entering;
2, expansion chamber constancy of volume, does not now compress.
Preferably, piston cavity is positioned at communicating with the external world to side cavity of expansion chamber.
Preferably, what piston cavity was positioned at expansion chamber is firing chamber to side cavity.
Preferably, heating equipment enters expansion chamber depth adjustable.
Preferably, heating equipment is heating stick.
Preferably, be provided with the regenerator be communicated with by valve control with firing chamber, the high-temperature gas of regenerator is connected with the import of heating stick.
Preferably, the front end of heating stick is the cold junction without heating function, and rear end is fire end.
A kind of method of work (heating stick is the situation in cold junction and hot junction) of heat source type motor, is characterized in that:

F, repetition steps A.
The working principle of the invention is just the introduction of heating equipment, and after introducing, heating equipment plays following effect:
One: heating stick is the parts of a 3-D solid structure, will certainly take certain space after heating stick extend into expansion chamber, therefore heating stick is certain to compress further the air in expansion chamber;
Two: on the other hand heating stick can heat by the air after compressing, for increasing the pressure of air after compression, realize high compression ratio.
After arranging heating stick, heating stick can improve the pressure in expansion chamber from both direction (compression, heating), and the negative pressure type engine solving original application produces that negative pressure is little, motor volume this problem large.
Heating stick can be made definite shape by demand, directly by the mode of heat trnasfer or gas medium conveying, heating stick is heated reach the operating temperature of motor.
The heating-up temperature of motor also has the large rising space, and (such as laser heating, arc heating) makes the volume of motor reduce further, and structure is also compacter.This technological scheme electric energy is converted to technology that mechanical energy becomes another highly effective except motor.Expanded the space of more wide model for electric energy is converted to mechanical energy, its technical advantage is apparent.
The bottom end closure of cylinder, increase a heating equipment, this heating equipment is arranged on the bottom of cylinder, and by piston, cylinder bottom, heating equipment forms a closed space, is called " expansion chamber ", the gas of a sealing atmospheric pressure in " expansion chamber ".
Expansion chamber can be positioned at outside piston top dead center or outside lower dead center.
Meanwhile, heating equipment can enter expansion chamber along cylinder end for making trouble freely, and its inlet is controlled.
Heating stick enters expansion chamber two functions:
1, the gas of compression-expansion indoor;
2, the gas in heat expansion chamber makes it expand, and because its amount entering expansion chamber is controlled, the pressure produced after compressing with this its is controlled with adding in thermal expansion.
The thermal source of heating comes from the high-temperature gas in recover, and heating stick is remained, and its desirable operating temperature, high-temperature gas send into heating stick one end by a turbine, and gets back to heater by the road from the other end of heating stick.
The beneficial effect of the invention shows:
1, high compression ratio is achieved by the flexible of heating stick: when piston movement is to lower dead center, heating stick extend in expansion chamber, heating stick is occupied in expansion chamber on the one hand, further compression cylinder volume, on the other hand, heating stick heats the gas in expansion chamber, improves compression ratio.
2, heating stick is selected,
3, the cold and hot chamber of former Stirling engine is separated, and the air in cold and hot chamber returns to circulate, and compares Stirling engine, and cold and hot chamber one, structure is simpler.
4, without discharge.
This heat source type motor is compared with motor, and its conversion thermal efficiency ratio motor is higher, and possesses the outstanding output characteristics of internal-combustion engine.
