Description
Technical field
The invention belongs to the external-combustion engine field of power machinery system, is the novel external-combustion engine of one based on pneumatic principle invention.
Background technique
External-combustion engine is also referred to as outer combustion-ing engine, although it and internal-combustion engine are all utilize the interior of fuel to be converted into mechanical energy, their working method is but very different.Wherein internal-combustion engine is that the heat energy that fuel and air mixture burns producing in cylinder combustion is converted into mechanical energy, and external-combustion engine is the High Temperature High Pressure products of combustion obtained burning in outer cylinder directly passes in external-combustion engine, products of combustion is made to expand and its kinetic energy is converted into mechanical energy simultaneously, or utilize products of combustion to carry out the working medium (as utilized gas heating water in steam power plant) of Heating Cyclic, make working medium expansion work be converted into mechanical energy, the power plant of these mode of work-doing are called external combustion power plant or claim external-combustion engine.
Existing external-combustion engine mainly contains piston type external-combustion engine, turbogenerator, Stirling engine etc., their basic functional principle are all be the transposition of mechanical energy by the thermal power transfer of outside fuel, these external-combustion engines are because its structure is simple, steady operation and other merits, be widely used in every field respectively, as torpedo, light-duty diving under water device etc.Because external-combustion engine is widely used in the power of the running gear under water such as torpedo, light-duty diving under water device, according to the requirement of these plant running such as torpedo, light-duty diving under water device, external-combustion engine should meet the requirement of high power and electrodeless variable-speed simultaneously.In current existing external-combustion engine, Stirling engine is due to complicated structure, shortcomings such as specific power is lower and do not have extensive use, and most widely used motor is piston and this two classes motor of turbine, such as lot of domestic and foreign hot power torpedo all adopts piston type external-combustion engine or turbogenerator mostly.But these two kinds of motors also have the defect of himself, be mainly manifested in the contradiction between high power and stepless change, wherein piston type external-combustion engine can stepless change on a large scale, but the power stage of piston type external-combustion engine is limited, cannot meet the power requirements at a high speed.Just require to develop turbogenerator to meet this power, and turbogenerator also has the defect of himself, although it can meet the equipment such as torpedo, light-duty diving under water device to the high speed of a ship or plane, high-power requirement, but mechanism and Economy decline larger when turbogenerator power system realizes large-scale stepless speed change, therefore it is only suitable for stepless change among a small circle, cannot meet the requirement of large-scale stepless speed change.In sum, although existing external-combustion engine has structurally carried out a large amount of optimization and improvement, but all because motor self structure and working method, limit its breakthrough in some aspects, as limited in piston type external-combustion engine output power, the major defect of turbogenerator is then that it cannot meet the requirement of large-scale stepless speed change.
In order to overcome the above-mentioned shortcoming of existing external-combustion engine, people are by constantly improving some methods of operation and the structural parameter of motor, as changed working room's shape of piston type external-combustion engine, change turbogenerator leaf grating shape etc., but eventually because the structure of available engine self and the restriction of working method, make their efficiency improve limitation, cannot solve from basic the shortcoming that existing external-combustion engine can not meet high power and electrodeless variable-speed requirement simultaneously.
China Patent No.: 201220001639.8, publication date: on November 21st, 2012, disclose the patent document that a name is called liquid piston external combustion engine, this model utility discloses a kind of liquid piston external combustion engine, comprise gas-liquid cylinder, hydraulic power mechanism, liquid working substance send-back system and boiler, described gas-liquid cylinder is communicated with through the vapor outlet port of gas working medium control valve with described boiler, described gas-liquid cylinder establishes relief opening, gas exhausting valve is established in described exhaust ports, described gas-liquid cylinder is established liquid working substance export and liquid working substance refluxing opening, described liquid working substance outlet is communicated with the power liquid entrance of described hydraulic power mechanism, the liquid outlet of described hydraulic power mechanism is communicated with described liquid working substance send-back system, described liquid working substance send-back system is communicated with described liquid working substance refluxing opening.This model utility eliminates the piston crank linkage mechanism of motor, has the advantages such as efficiency is high, volume is little, lightweight.But this model utility is because the structure of self and the restriction of working method, and output power is still limited, can not meet high-power output.
China Patent No.: 99816745.2, publication date: on 06 05th, 2002, disclose the patent document that a name is called the turbogenerator of raising the efficiency, this turbogenerator has a rotor and a fluid flowing passage, this fluid flowing passage extends through compression, burning and expands or the turbine stage, wherein fluid flows through fluid flow channel and driving rotor.Turbogenerator has one or more stator-rotator-stator module and uses a flat turn sub-disk with turbine blade.Catch fluid thus can raised temperature and pressure and fluid is kept closer to the state of constant volume between main combustion period between main combustion period simultaneously.Fluid repeatedly to be reentered in rotor thus makes the moving member of turbogenerator periodically be exposed to the different piece of cycle of engine, in order to thus the mean temperature lowering parts allows higher compression ratio and combustion temperature.But this invention cannot meet the requirement of large-scale stepless speed change.
