Description

Retroacting engine

The utility model relates to a kind of Retroacting engine, and this motor is to utilize cooling back-heating, punching press compression, the new work engine of isochoric combustion and jet reaction work done.

Motor is a kind of ordinary skill of extensive use, and after producing the steamer in modern age, all kinds have appearred in the needs along with science and technology development and productive life, the motor of various uses.Wherein the technology of vapour, diesel engine is gradually perfect, though gas turbine and rotary piston engine have just begun to promote, has also run on material, the thermal efficiency and service cycle and is difficult to the shortcoming that overcomes in a short time.Particularly the thermal efficiency of these several motors of widespread usage also can not surpass 50 percent now, and weight/power ratio also is difficult to drop to the level of air breathing engine.Though domestic and international vast researcher is attached great importance to this work, drop into great amount of manpower and material resources and captured this difficulty, also there is not Updated product to occur so far.

The purpose of this utility model is to propose a kind of thermal efficiency that makes to improve greatly, and weight/power ratio is near the Retroacting engine of air breathing engine.

The purpose of this utility model is realized by following technical proposals: a kind of Retroacting engine, a fixedly wheel seat is arranged, fixedly wheel seat is provided with left end cap and right end cap, left end cap is communicated with the relief opening of described compressor, described transmission shaft by Bearing Installation on a left side, on the right end cap, an active wheel is installed at the middle part of transmission shaft, this active wheel is by interior ring, outer shroud and stator constitute, in, a plurality of described firing chambers are housed between the outer shroud, on encircling in the suction port of this firing chamber is located at, exhaust nozzle is located on the outer shroud, a fixed inducer is installed on the described right end cap, this inducer is provided with a plurality of radial-flow guide vanes, this inducer inner edge is provided with gas collection runner and flow outlet, and in the zone of this flow outlet between 230 ° of-360 ° of angles, this air flow outlet is provided with oil nozzle and spark plug, the inwall in zone is provided with many reflection grooves between 180 ° of-360 ° of angles of described fixedly wheel seat, and this reflection groove is in communication with the outside by the duct of right end cap.

Figure 15 is a working principle schematic representation of the present utility model, working principle of the present utility model is: by compressor with the gas compression to 4 that sucks to 6 air pressure, gas enters the space outerpace of active wheel and firing chamber from left end cap, gas is accelerated when being moved into inducer backward under the effect of stator, the temperature of gas will be enhanced, also cooled off simultaneously active wheel and on the firing chamber, so this motor can be provided with special-purpose cooling system, the gas that enters inducer flows along fixing circulating direction, do entad to flow from the circumferential center of circle earlier, it is moving to remake diverted flow then, become clockwise direction at last and enter firing chamber on the active wheel from the inducer air flow outlet, rotation of working time counterclockwise rotation this moment, thereby compressed-air actuated flow direction is opposite with air inlet of combustion chamber moving direction, the exhaust nozzle of firing chamber is in closed position, therefore, pressurized air produces the punching type compression once more in the firing chamber, when active wheel moves forward in the process at 130 ° of angles, be full of pressurized gas in the firing chamber, the air inlet compression process finishes, when active wheel continues to move forward, the oil spout of oil nozzle elder generation, the spark plug post-ignition, gas rapid burning expansion in igniting back forms high-temperature high-pressure fuel gas, simultaneously the exhaust nozzle of the firing chamber on the active wheel is in the reflection groove position on the fixing wheel seat, and be in opening state, the energy of combustion gas in exhaust nozzle, change into kinetic energy with high velocity shock to reflection groove, active wheel produces running torque and externally exports mechanical work, waste gas after the expansion acting is discharged to atmosphere by the duct of right end cap, active wheel moves 20 ° of angles more forward and discharges all waste gases, and a thermodynamic cycle is finished.

Compared with the prior art the utility model has following advantage:

1, be rotary component owing to the utility model has only an active wheel in whole conversion process of energy, its cooling is the pressurized air that does work by not, so the energy of mechanical friction and cooling loss reduces half than vapour, diesel engine.

2, again because firing chamber of the present utility model is that isochoric combustion does not need very high suction pressure, so the energy loss ratio gas turbine in compressor and exhaust also can reduce half.

3, simple structure of the present utility model can have 2 to 4 firing chambers to work at the same time on the active wheel, so its weight/power ratio can surpass gas turbine and approaching jet level of starting.

The utility model is described in further detail below in conjunction with drawings and Examples.
