Description
The invention belongs to explosive motor and Te Tao double technique field.This machine is a kind of not bent axle, connecting rod, circulation radiating and cooling in water route not, and do body, piston and critical piece with ceramic new material, constitute by body and rotary-piston and to fire the working room, take jet supercharging and eliminating to fire that working room's waste gas, piezoelectricity spark are ignited and high temperature fires and combines the ceramic rotary piston ingine of directed outburst, three grades of propellings.
After Bo Te invention internal-combustion engine, world industry has entered a new period, and aviation industry is developed rapidly.Over more than 100 year, internal combustion engine development is very fast, and is of a great variety, but the utilization ratio of most energy is very low; Some newly develop as rotor, thermal insulation, wankel engine etc.Because structure problem can't come into operation it.Though 1 year new work engine competitively done by some countries of west, but still do not have breakthrough; Existing Aeronautics and Astronautics, navigation is jet, gas engine etc., though can utilization ratio higher, cost is high, development is subjected to certain limitation.Therefore existing to using four-stroke ic engine analysis widely, discuss and foundation to set up drawing of new architecture.
1, the air inlet of quartastroke engine, compression, four strokes that break out, scavenge move in circles, and wherein have only an explosion stroke work done.Compression, exhaust all are power consumptions, and particularly the compression stroke power consumption is high, and the diesel engine compression strength is up to 30～45kg/cm
2, and outburst acting pressure is also nothing but 60～90Kg/cm
2About, this almost half energy charge is in compression stroke.Certainly, in compression stroke, a part can make the gas molecule in the cylinder quicken thermal motion by compression, promptly by compressed action, merit is converted to interior energy (show as and improve temperature in the cylinder), discharges again in next explosion stroke.
2, quartastroke engine be by piston by connecting rod and bent axle carry out can transmission because crankshaft-and-connecting-rod interacts, make to-and-fro motion be converted to rotation.And in outburst acting process, piston is changed with its motion by the gas surge pressure, and the snap point of outburst acting is not apart from the position in maximum, force.Bent axle connecting rod and accumulator-flywheel is changed mutually or cross action under, direction changes suddenly, energy is cancelled each other, this is two of the low major reason of the utilization ratio of four-stroke ic function.
3, quartastroke engine, the overwhelming majority takes circulation heat-shift in water route in the body, reduces temperature cylinder, therefore, the big calorimetric (energy) that outburst is produced is passed to airspace by water tank and body, has exchanged piston for multipotency so and has normally moved in cylinder.This is the chronic disease that is difficult to overcome that this body structure of quartastroke engine causes, and also is the high basic reason of power consumption.Yet, adopt ceramic new material, improve the resistant to elevated temperatures ability to bear of cylinder, the utilization ratio that can enable is significantly increased, but far can not bring into play the due effectiveness of fuel.Calculate according to mechanical equivalent of heat formula (=4.18 joules on 1 card), the perfect combustion of per kilogram oil, the heat energy of generation is equivalent to 17 horsepowers of merits of being done in 1 hour; Obtained X～195 diesel engines of quality award from the ministry matter prize, every horsepower of oil consumption 180 grams, one kilogram of oil can obtain 5.56 horsepowers of 1 hour institute's works, and the utilization ratio of in view of this current quality award from the ministry diesel oil function also is very low, and the utilization ratio of its energy only has 1/3.In just nearest period, after some countries utilized new material to transform quartastroke engine, though the utilization ratio of energy is significantly increased, the utilization ratio of energy was still very low.On " Du Zi " 2.8 liter of 3 cylinder ventilation type diesel engine basis, make 3 cylinder four-stroke ceramic diesel engines as kyoto, Japan pottery company, saved air cooling system, be contained on the sedan car, travelled one hour with ceramic new material.Experiment showed, that its conventional diesel engine than equal scale raises the efficiency 30%.But the utilization ratio of energy is also less than 1/2.Therefore, the effectiveness of fuel be given full play to, just existing quartastroke engine structure must be changed.
Six during the last ten years, and world's advanced industrial country is carrying out the remodeling development work to explosive motor always, and wankel engine, adiabatic engine etc. are successively manufactured experimently.But eventually because of self structure and lubricated, not success of closed question, and those imagination and lessons of meeting Der Grundsatz der Maschinen all can be used as useful reference, so that design meets new architecture-ceramic rotary piston ingine efficient, energy-conservation, simple in structure.
This machine is heated according to burning release heat energy, gas and produces the principle of expansive force, design is taked hot pressing casting mold moderate heat (1000～1125 degree) vacuum control with ceramic new material silicon carbide, silicon nitride, the new process of high temperature (2400～2450 degree) sintering, quick cooling, fabrication and processing rotary-piston, body and critical piece thereof, revolve piston under 1200 degree conditions, keep bending strength to be not less than 60Kg/ square millimeter and good self-enrichment.Adapt to high temperature 1300～1400 degree (combustion centre can reach 2500～2800 degree), 90 millimeters of diameters, long (thick) 36 millimeters of (1800～20000 rev/mins) piston at a high speed, have in 18 millimeters of 4 diameters, long 26 millimeters bullet shaped partly to fire the chamber, its axis becomes 120 degree angles with fire plug radial line.Rotary-piston is fixed in the body (2) by main shaft (17), 90 millimeters of body internal diameters.Body have outer partly fire chamber (12), boosting chamber (10), first pushing chamber (6), second pushing chamber (7), jet air intake pressurized pipe (15) and valve 11A-B, partly fire chamber flue gas leading (9) in getting rid of, partly fire outward oiling valve (13) and spark plug (16) are arranged in the chamber (12), the order that is in operation and interiorly partly fire chamber (3A-D) to constitute two ends be that hemispheric garden cylindricality fires the working room, its capacity is 11.7248 milliliters.Because the interior chamber direction (becoming 120 degree angles with the rotary-piston radial line) that partly fires is fixed, so determined the impact direction of outburst high pressure draught, the gas shock power that breaks out gas shock power, jet pressurized energy, three grades of propelling forces and scavenge etc. all plays a driving role to rotary-piston, having changed in the past the four-stroke ic engine reverse compression is compression in the same way, from outburst, through pushing chamber, jet air intake pressurized with scavenge etc., form a system of propelling in the same way.
The objective of the invention is: utilize ceramic new material intensity height, adapt to wear-resistingly, high temperature resistant, the strong and self-enrichment of corrosion resistance changes the high and lost serious structure of energy of energy consumption that explosive motor in the past is difficult to overcome because of structure and material causes; Make the ceramic rotary piston ingine of design avoid acting in opposition and can counteracting, reduce energy and scatter and disappear, give full play to fuel answer effective force with improve can utilization ratio.
