This device is formed a work cycle by air inlet stroke, compression stroke, expansion stroke and exhaust stroke.
(1) the 1st stroke: piston moves to lower dead center by top dead center, and promptly the crank of bent axle forwards 180 degree (when piston was positioned at the 1st stroke top dead center, the crank position of bent axle was decided to be 0 degree) to by 0 degree.In this stroke, a large amount of air gets into cylinder, and therefore, the 1st stroke is called the air inlet stroke again.The 1st step, a large amount of air entered in the cylinder through suction tude (6), intake valve (3).The 2nd this moment in step, the 1st stroke was started working, and piston (2) is begun to move to lower dead center by top dead center.The 3rd step while intake valve (3) is opened already, and a large amount of air enters in the cylinder, moves to lower dead center at piston, and intake valve (3) is closed, and high pressure-charging oxygen-enriched air input control system (15) is opened and closed subsequently simultaneously.The 4th step high pressure-charging oxygen-enriched air pressure injection device (4) opens and cuts out subsequently.
(2) the 2nd strokes: piston moves to top dead center by lower dead center under the huge effect of inertia of high-quality flywheel, and promptly the crank of bent axle forwards 360 degree to by 180 degree.After intake valve (3), high pressure-charging oxygen-enriched air pressure injection device (4) were closed, a large amount of fresh airs and high oxygen-enriched air in the cylinder were compressed under the active force of piston, so be called the gas compression stroke in this stroke.
(3) the 3rd strokes: piston moves to lower dead center by top dead center, and promptly crank forwards 540 degree to by 360 degree.In this stroke; Fresh air, high oxygen-enriched air change into the oxygen enrichment mixing air of high pressure-charging under the effect of piston; High energy oil emulsion combustion agent (8) expects that through compressing in middle pressurized fuel pump (9), the preparatory spray high-temperature oxygen-enriched burning input control system (10), high energy oil emulsion combustion agent pressure multi-hole injector (11) enter into cylinder after high temperature porous medium heat retainer (27) the preheating gasification of high temperature precombustion chamber (26);

Before piston will be near top dead center; High energy oil emulsion combustion agent (8) through middle pressurized fuel pump (9), compress into material high-temperature oxygen-enriched burning input control system (10) in the spray in advance, high energy oil emulsion combustion agent pressure multi-hole injector (11) enters into cylinder after high temperature porous medium heat retainer (27) the preheating gasification of high temperature precombustion chamber (26), the charge kindling material combustion agent of lighting a fire automatically of anti-knock homogeneous is fired and is entered in the cylinder after high temperature porous medium heat retainer (27) preheating of agent pressure multi-hole injector (11) in high temperature precombustion chamber (26) gasified through homogeneous light a fire the automatically charge kindling material combustion agent input control system (25), high energy oil emulsion of charge kindling material combustion agent conveyer (24), homogeneous of lighting a fire automatically.Automatic homogeneous igniting promptly takes place in the 2nd step high temperature combination gas, under homogeneous is lighted a fire the effect of charge kindling material combustion agent automatically, can produce numerous fire and examine the spontaneous combustion of automatic homogeneous volume, carries out the high temperature lean combustion (can prevent the pinking generation) of high temperature homogeneous.The 3rd step high energy oil emulsion combustion agent (8) is fired after high temperature porous medium heat retainer (27) the preheating gasification through high temperature precombustion chamber (26) in of charging high-temperature and low-oxygen combustion input control system (23), high energy oil emulsion combustion agent pressure multi-hole injector (11) high-voltage high-speed through high pressure fuel pump (22), back spray high pressure master and is entered into and lead the combustion high-temperature and low-oxygen combustion in the cylinder, and ongoing strong combustion is burnt and emitted huge heat super large pressure expansion and do work and carry out the output of great power.The 4th step superelevation calorific value clean environment-friendly purify combustion-supporting combustion gas through the superelevation calorific value novel environment friendly combustion-supporting combustion gas conveyer of Cress (19), back spray purified feed high temperature reducing fire novel gas input control system (20), high temperature porous medium heat retainer (27) the preheating gasification of the combustion-supporting gaseous-pressure sparger of novel environment friendly Cress (21) through high temperature precombustion chamber (26) in after high speed enter in the cylinder, carry out the combustion-supporting perfect combustion of high temperature of the height purification of environment-protecting clean further.The high flame burning of spray lean-burn gas finishes in advance when piston has moved 5% stroke.The 5th step, at this moment, the main combustion in the cylinder was carried out already when piston has moved 10% stroke, and inner pressure of air cylinder sharply jumps.The burning completely of homogeneous anoxic volumeization of the superhigh temperature of comprehensive high pressure has promptly taken place in the 6th step already in the cylinder when piston has moved 15% stroke.The 7th step, the strong combustion in the cylinder finished when piston has moved 20% stroke, can reach the purpose of the bigger Driving force of generation perfect combustion and that increase substantially engine output that ultra micro discharges.
(4) the 4th strokes: piston moves to top dead center by lower dead center, and promptly crank forwards 720 degree to by 540 degree.In this stroke, the product clean air (18) after the perfect combustion is discharged cylinder through exhaust valve (5), is called exhaust stroke again.The 1st step exhaust valve (5) is opened, and the 2nd step, exhaust valve (5) cut out when piston moves to top dead center by lower dead center, and the 3rd step, next circulation was about to begin.
The unconventional burning ultra micro discharging of high pressure-temperature: ultralow oxygen burning is under normal conditions, and burning can not be carried out.But when the 1st, the 2nd, the 3rd stage since oxygen-enriched air, fuel already in the high temperature precombustion chamber after the high temperature preheating premixing gasification through the porous medium heat retainer of high temperature; Whole combustion space all is in the very high high temperature; Conventional burning is temperature height in the flame burning district only, and temperature is lower outside the zone of combustion.High temperature can be expanded flammable range significantly, homogeneous combustion in volume.Make that the centuries is considered to impossible thing in the past, under the condition of high temperature, be achieved.Though high temperature may cause generating too high nitrogen oxide,, just be not easy to take place because oxygen concentration is lower.Combustion phenomena of the stability that so the high temperature reducing fire is brand-new unconventional ultra micro discharges.
