Power system as shown in Figure 2, the utility model also comprises blowing device 20, is arranged on the side of cooling system 11, for improving the temperature of cooling liquid in cooling system 11.Preferred blowing device 20 is fan.Certain the utility model is not limited to blowing device 20, such as, as shown in Figure 3, in power system peculiar to vessel, be ambient water (as seawater, river, river etc.) for what improve coolant temperature in cooling system 11, by the spray of the routine of spray equipment 22 or the mode of water-bath, through the heat exchanger surface of cooling system 11 heat of ambient water is delivered to the cooling liquid in cooling system 11.
The utility model exports gas puff Z-pinch signal by gas puff Z-pinch device 14, to control startup and the stop timing of jet plug 4, as shown in Figure 2, control command is delivered to the control port of jet plug 4 by gas puff Z-pinch device 14 by gas puff Z-pinch line 16, specifically can be realized by conventional software operation.The working pressure preferably 3 ~ 40MPa of jet plug 4.
What store in the heat insulated tank 1 that the utility model adopts is liquid gas, the temperature normality of liquid gas is at-200 DEG C, usual needs external world insulation, so the utility model have employed heat insulated tank 1 to store liquid gas, liquid gas in heat insulated tank 1 have do not heat up, do not seethe with excitement, non-bloating feature, ensure that stable output, reduce medium natural wastage.
Water bath carburetor 3 uses as heat exchange exchanger in the utility model, and the cooling liquid realizing liquid gas and cooling system 11 carries out heat exchange exchange, in the utility model, the effect of cooling system 11 is for water bath carburetor 3 provides heat, the temperature of cooling system is normal temperature, and the temperature of liquid gas is-200 DEG C, at this moment, the heat energy that cooling system 11 can not be converted into power unnecessary and liquid gas carry out heat exchange, directly for power plant provide pressurized gas to carry out driving power device, during work, gas in the cylinder 5 of power plant is in the process expanded, temperature can decline rapidly, at this moment the heat of supplementary cylinder 5 can be carried out from the side-walls heat absorption of cylinder 5, the bulk temperature of power plant then can constantly decline, at this moment need cooling system 11 to continue heat absorption from environment and carry out supplementary power plant.The effect of original cooling system 11 is made into heat absorption concurrent heating system by the utility model, and this mode constantly can discharge cryogenic gas in environment, serves good environmental-protection function to physical environment.
Gas puff Z-pinch device 14 obtains the size of jet opportunity and jet amount according to throttle opening amount signal 17 and fire signal 15, then controls jet plug 4 and realizes jet.
Power system operational flow process: the liquid gas of heat insulated tank 1 is pressed into water bath carburetor 3 by high-pressure ultra-low temperature pump 2, the cooling water that water bath carburetor 3 is carried by cooling system 11 forms circulation, constantly bring heat for water bath carburetor 3, this heat makes liquid gas heat up, heat absorption boiling is expanded, keep existing pressure (i.e. the pressure of 3MPa or more than 3MPa), the gas at normal temperature forming high pressure exports for subsequent use, the cooling liquid of cooling system 11 plays heat sinking function, although the temperature of cooling liquid is lower than ambient temperature, but still far away higher than the temperature of liquid gas, be enough to liquid gas intensification boiling is expanded.The gas at normal temperature of the high pressure that water bath carburetor 3 is formed is delivered to jet plug 4, for power plant provide working medium, makes power plant complete the continuous circulation of air-breathing-compression-acting-exhaust stroke.
Power system utilizes the process of environment thermal energy to have three processes:
The first, gasification, the gas at normal temperature that liquid gas becomes high pressure by the heat of water bath carburetor 3 absorption cooling system 11 is for subsequent use, fills the gas at normal temperature of high pressure, eject instantaneously when needs in the pipeline between water bath carburetor 3 and jet plug 4; Specifically, liquefied gas vapo, close-200 DEG C of liquid gas, the mixture be made up of liquid oxygen, liquid nitrogen and other inert gases; Liquid gas at least will exceed 160 DEG C relative to the temperature (as gas, water, soil are between-40 DEG C ~+60 DEG C) of environment; Therefore, the material of environment is relative to liquid gas, belong to high temperature material, the heat of environment transmission is enough to make liquid gas intensification ebullition, gasification, becomes gas expansion nearly thousand times from liquid, is at this moment limited in a very little space, huge pressure will be produced, become to contain and have larger acting potentiality, be that potential energy does work in decompressor by thermal power transfer, be kinetic energy by potential energy converting and energy;
Second, the gas at normal temperature of the high pressure sprayed at jet plug 4 runs into the air that the end through compression stroke sucks and (is not mixed into fuel, the now difference that designs according to cylinder compression ratio of air temperature, temperature rise is different, to reach between 160 ~ 600 DEG C or higher), owing to being in compression stage, the gas entered by intake valve 9 obtains the gas at normal temperature heated up with the high pressure sprayed into and is mixed to form mixed gas, high pressure gas expansion is lowered the temperature, but mixed gas total amount, the more original pressure of stagnation pressure rises rapidly, at this moment formed simulation close to the original pressure of engine combustion mode lower cylinder (namely Spark ignition type be about 3MPa, compression-ignited is about 8 MPa), because the gas at normal temperature of the high pressure sprayed into can reach 3 ~ 40 MPa, cylinder 5 now can reach rapidly due stress level, in the expansion stage, along with mixed gas instantaneous expansion, (namely Spark ignition type is expansion about 10 times in the expansion of mixed gas, compression-ignited is expansion about 20 times) promote piston 6 do work after Power output time, because the pressure of air pressure reduces rapidly, theoretical according to air thermodynamic (al) adiabatic expansion of being correlated with, temperature must be caused to decline, the temperature of gas of discharging finally by exhaust valve 10 between-10 ~-30 DEG C (i.e. spark-ignition engine) or-20 ~-40 DEG C be between compression ignition engine, this process, by intake valve 9 suction gas temperature 10 ~ 30 DEG C between, the temperature of the gas of being discharged by exhaust valve 10 is between-10 ~-30 DEG C or-20 ~-40 DEG C, at this moment the heat of suction gas must be converted to kinetic energy,
3rd, due to cooling system 11 ringing, the temperature of cylinder 5 can keep the scope close to ambient temperature all the time, when after gas expansion cooling, heat exchange between cylinder 5 and mixed gas, must pass to mixed gas the heat of cylinder wall, supplements the heat that part is lost in inflation process, simultaneously because heat exchange belongs to endothermic process, air can be made further to heat up supplementary expansion potential energy.Cylinder 5 inner carrier 6 movement velocity is slower, and rotating speed is lower, and the heat that cylinder 5 and piston 6 pass to expanding gas is more.
