Abstract

A compound engine is a double energy converter to transform the pressure energy and flowing kinetic energy of working medium into mechanical energy. Its two converting mechanisms are serially connected. After the working medium gets energy from air compressor and fuel provided by oil sprayer, pressure wheel and power turbine are used for energy conversions. Its advantages are low energy consumption, less pollution and use of more kinds of fuel.

Description

Compound engine

The present invention relates to a kind of motor, particularly consume energy low, pollute little and use pluralities of fuel.

In available engine, mainly contain two classes.One class is the piston or the rotary engine of depended on pressure energy work done, another kind of is with the flow turbogenerator of kinetic energy work done of working medium, power consumption is high during their work, pollute big, it is poor to be suitable for pluralities of fuel, what have is not all right at all, single as petrol engine and diesel motor fuel, aspect power consumption, as the former CA6102 h type engine h minimum power consumption be 225 the gram/horsepower-hour, relatively the lower CA6110 serial diesel engine of power consumption be 170～155 grams/horsepower-hour, and the complicated turbine composite adiabatic diesel engine power consumption of the U.S. also reaches 127.1 grams, this class is with the motor of pressure energy work done, be heat energy by fuel the gas that is compressed to certain pressure, work done after a few multiplication of voltage power that raise again.When working with the turbogenerator of the kinetic energy work done of flowing, be after working medium obtains certain pressure by gas compressor earlier, heat energy by fuel elevates the temperature, expands again, the high speed work done that produces at the nozzle place, this class motor reaches behind nozzle place puffing at a high speed, and wherein the pressure before and after the decompression is not utilized and has slatterned, and the power consumption of this two classes motor is reduced, available engine itself can't be accomplished, needs to be used just and can to finish with other energy-conservation parts.

The purpose of this invention is to provide a kind of new structure, consume energy low, pollute for a short time, and can use the motor of pluralities of fuel.

The present invention be achieved in that hybrid engine be with pressure can work done and the flow mode of kinetic energy work done of working medium combine, transformation of energy realizes by pressure wheel and power turbine, pressure wheel is arranged on the power turbine front, both tandem arrangement, working medium in nozzle exit decompression, expansion, sprays to power turbine earlier by pressure wheel again after the acceleration, wherein motive power wheel is formed by rotor with a plurality of blades that it is hinged, and blade radially cuts with scissors in rotor periphery and draws arrangement.

Below in conjunction with accompanying drawing the present invention is described in further detail and illustrates:

Fig. 1 is a structural representation of the present invention

Fig. 2 is the structural representation of pressure wheel

Fig. 3 is the work schematic representation of pressure wheel in the pressure chamber

With reference to accompanying drawing: start gas compressor 1. by starting drive earlier during work, its running is calmed the anger, the moving air of the pressure flow that is provided is introduced into firing chamber (or directly entering the pressure chamber 4.) 5. by connecting pipeline, the firing chamber 5. in the high pressure pulverized fuel provide continuously be provided by oil spout (combustion) be mixed into inflammable gas, after ignition mechanism is once lighted, become the pressure flow matter of starting building, flow to the pressure chamber 4., be provided with convergent shape jet expansion 6. at pressure chamber's opposite side, pressure reduces pressure herein, make working medium advancing in the pressure chamber, go out the interruption-forming pressure difference, the blade that is contained in the pressure in pressure chamber wheel is subjected to this unbalanced pressure, and rotate towards jet expansion low pressure area 6. the zone of high pressure that 6. pressure wheel is located by import, working medium can convert partial pressure to mechanical energy by pressure wheel earlier like this, 7. working medium locate the decompression acceleration at jet expansion simultaneously, sprays to power turbine again, and mobile kinetic energy is converted to mechanical energy by power turbine once more.Working medium is divided into three zones by in the process of pressure chamber by pressure wheel, is high pressure section in import A district, is pressurize section (except that leaking) in target phase B district, and in the end one section C district is the decompression accelerating sections.After working medium the convergent shape nozzle puffing by here accelerates to design load, spray to power turbine, compressed like this gas working medium is just the energy that obtains, two kinds of working methods by pressure wheel and power turbine have converted useful mechanical energy to, reach the inaccessiable effect of other motor.In this conversion process of energy, the effect of firing chamber, only provide heat energy at this, the temperature of working medium is risen, improve the nozzle place refrigerant flow rate and with, the still gas compressor that plays a major role 1., pressure wheel 2. with power turbine 3., the former provides energy, both realize the kinetic force conversion back, the fuel that oil spout (combustion) device provides is continuous burning in the combustion chamber, when changing use fuel, only needs oil spout (combustion) device is changed the position, just the fuel of conversion can be sprayed into firing chamber and burning, thereby realize using the purpose of pluralities of fuel.
