Background technique
The heat energy of existing petrol engine about 30% is discharged through waste gas, and about 35% heat energy is taken away through the water of cooling system, and the heat energy of total nearly approximately 70% can not do work, and the heat energy of real acting is less than 30%.The researcher of countries in the world is devoted to improve the working efficiency of petrol engine always; Since original mentality of designing be confined to let always combustion gas better detonation reach clean-burning purpose; The combustion gas molecule is still still done three dimensional space and is done random Brownian movement in cylinder body, therefore the thermal efficiency of advanced petrol engine only can reach 30% at present.How increasing substantially the thermal efficiency is a problem demanding prompt solution.
Summary of the invention
The purpose of the utility model provides a kind of two hole high-pressure gas injected petrol machine ceramic-lined chambers; Can make the combustion gas molecule in cylinder body, become orientation movement by random Brownian movement; Reduce the firing chamber heat radiation, thereby make mechanical efficiency greatly improve, reduce energy consumption.
The technological scheme of the utility model is: a kind of two hole high-pressure gas injected petrol machine ceramic-lined chambers comprise ceramic-lined chamber 5, ceramic plenum chamber 3, tighten up screw thread 6, metal discharge ring 7, gas jetting hole 8, conductiving metal strip 9, metal transmission rod 15, ceramic plenum chamber metal discharge top 18, spill ceramic plate 19, high pressure electrostatic generator 13, high voltage ignition control panel 14.Ceramic-lined chamber 5 is embedded in the metal cylinder cap 4 through tightening up screw thread 6, is provided with 3, two ceramic plenum chambers 3 of two ceramic plenum chambers in the ceramic-lined chamber 5 and is symmetrical line distribution, this axis of symmetry and exhaust valve and intake valve orthogonal axe.Pottery plenum chamber 3 is the round platform cavity, and ceramic plenum chamber 3 tops are embedded with the ceramic plenum chamber metal discharge top 18 that tinsel constitutes, and this tinsel is connected with metal cylinder cap 4 through metal bar.Pottery plenum chamber 3 bottoms are provided with gas jetting hole 8, and the tip position of gas jetting hole 8 corresponding pistons 11 is inlaid with spill ceramic plate 19.Gas jetting hole 8 outer rims are inlaid with metal discharge ring 7, and each metal discharge ring 7 all couples together through conductiving metal strip 9.Conductiving metal strip 9 connects metal pipe box 17, is inserted with metal transmission rod 15 in the metal pipe box 17, and metal transmission rod epimere is provided with insulating ceramics cover 16, makes metal transmission rod and metal cylinder cap keep insulation.The outer end of metal transmission rod 15 is connected with high pressure electrostatic generator 13, and high-voltage generator 13 connects high voltage ignition control panel 14 through lead, and DC electrical source 12 provides electric energy for high-voltage generator and high voltage ignition control panel 14.
The said high pressure electrostatic generator 13 of the utility model is the commercially available prod with high voltage ignition control panel 14.
The working principle of the utility model is: the petrol engine compression stroke finishes, and when arriving ignition location, two ceramic plenum chamber 3 interior gaseous-pressures reach maximum value.When providing a fire signal, high voltage ignition control panel 14 is transferred to high-voltage generator 13; High pressure electrostatic generator 13 just sends a plurality of continuous high direct voltage electrical pulses; After transferring to metal pipe box 17, process metal transmission rod 15 transfers to metal discharge ring 7 again; Gas between metal discharge ring 7 and the ceramic plenum chamber metal discharge top 18 is breakdown, realizes igniting.Pottery plenum chamber 3 inner high voltage fuel gas burings make that burning is very even, and burning produces the gas of HTHP; Meanwhile, after the igniting, get into expansion stroke, piston 11 beginnings are descending, and it is big that piston cavity becomes, and the combustion gas of ceramic plenum chamber 3 is ejected from gas jetting hole 8, burns while spray.Because the fuel gas injection of high temperature, high pressure comes out; Can cause ablation to piston head, the corresponding position at the top of piston 11 is inlaid with spill ceramic plate 19, has so just avoided the high-temperature damage of piston head; Effectively accept simultaneously the pressure of spraying high-pressure gas, effective anti-push piston.
In the acting process, on the one hand, Automobile Igniting Control plate 14 follow procedures send instruction; High pressure electrostatic generator 13 provides high-voltage pulse continuously and since combustion gas the acting process in, high-temperature fuel gas is in ceramic plenum chamber 3 internal combustion; Pottery constitutes heat insulator, and its temperature must be higher than the temperature of metal burner, (for example cylinder of diesel engine internal combustion temperature is higher than 1700 ℃); Be low-temperature plasma gas; Degree of ionization is less than 1%, but high-voltage pulse punctures the low of the required voltage ratio normal temperature of high-temperature gas, and electric energy consumption is lower.Breakdown combustion gas molecule is the plasma of ionization, is conductor.In the process of conduction, the high-temperature gas molecule is done orientation movement along direction of an electric field, directly promotes piston; On the other hand, the combustion gas of ceramic plenum chamber 3 is ejected from gas jetting hole 8, makes most of gas move along injection direction, in conjunction with above-mentioned two aspect factors, shows as on the macroscopic view that gas molecule is approximate does orientation movement.Gas molecule is originally done random Brownian movement at three dimensional space, does one dimensional motion now.Say that from physics principle when doing Brownian movement, molecule is impartial along the pressure of three dimensions, if molecule is done orientation movement, the pressure of three directions forwards a direction to, and pressure becomes original three times.Fuel gas injection makes mechanical efficiency greatly to improve.
In the process of acting, the firing chamber is the maximum zone of heat radiation, adopts ceramic-lined chamber to slow down cooling effect greatly, has improved chamber temperature, makes the process of combustion gas acting become the deflection adiabatic expansion by the deflection isothermal expansion, has improved heat power efficiency.
The beneficial effect of the utility model is: combustion gas is in the process of acting, and gas molecule is done orientation movement.On the one hand, utilize in the expansion stroke, main combustion process is carried out in ceramic plenum chamber 3, and combustion gas is ejected from gas jetting hole 8.Adopt two hole chamber structures can make the stressed distribution of piston head more balanced, make the distribution of exhaust valve and intake valve simultaneously, improved thermal stress distribution away from gas jet hole 8.
