Description
Technical field
The present invention relates to the method and apparatus of removable power and generation driving force, especially the method for work of internal-combustion engine and equipment.
Background technique
The history in existing 100 years of the motor of Carnot's cycle, its working principle: air-breathing, compression, blast, exhaust.Along with the also constantly raising of performance of development of science and technology motor,, but fail to make the thermal efficiency of motor to surpass 30% like technology such as increase valve, turbosupercharging, EFI, in-cylinder direct injections.Under the background of global oil, environmental crisis, the thermal efficiency of raising motor and environment protection emission have important and profound significance to the development of society.
CN200810007618 has proposed a kind of eight-stroke engine, and this motor has the working cylinder through work by combustion, is called combustion cylinders; Working cylinder with through the water vapor expansion acting is called the steam cylinder; Combustion cylinders links to each other through air flue with the steam cylinder, on the steam cylinder, water jetting apparatus is arranged; In combustion cylinders; After air experience " air inlet-compression-burning expansion acting-exhaust " four strokes; The high-temperature fuel gas that is produced gets in the steam cylinder through air flue, again experience " advancing High Temperature Gas-compression water spray-steam expansion acting-exhaust " four strokes, eight strokes altogether.Said air flue is the pressure stabilizing cavity structure.Above-mentioned eight-stroke engine utilizes exhaust heat-energy to be converted into steam, in fact efficient is very limited for conversion process again, and gained also may not be that institute works as, above scheme do not see get into practical.
In general, why the thermal efficiency of existing piston formula four stroke engine is no more than 30%, is because its explosion energy is not fully utilized, and also can't make full use of and caused, and also falls far short apart from theoretical efficient.This index of the compression ratio of motor has determined the unnecessary energy of blast working stroke must get into next working procedure exhaust, also has most useful power not to be utilized, with regard to having drained in vain.
Summary of the invention
The objective of the invention is: propose a kind of explosive motor that makes full use of two (one or three) bent axles of eight strokes two (one or three) row cylinder of heat energy; The setting method that the present invention proposes will make full use of most useful poweies exactly with device, makes the power of motor, efficient realize maximization and energy-conserving and environment-protective.
Technological scheme of the present invention is; The setting method of eight-stroke engine is all set up corresponding with it countercylinder to every cylinder of four stroke engine, and master cylinder is laterally parallel with countercylinder; Corresponding master cylinder 11 forms to interconnect through UNICOM's air flue 23 with countercylinder 12 and is referred to as one group; Master cylinder 11 is opened high temperature, high pressure, expanding gas that UNICOM's valve 24 makes master cylinder 11 burnings when the blast acting, through UNICOM's air flue 23 moments importing countercylinder 12; The exhaust valve 26 of countercylinder 12 cuts out with breathing valve 25, piston 7, the 8 motion actings in two cylinders 11,12 of one group in abundant burning, two cylinders of expansion driven major-minor 11,12.
The improvement of eight-stroke engine setting method is; Every cylinder of four stroke engine is all set up corresponding with it countercylinder and whole system device; Master cylinder (forming a line) is horizontal parallel position with countercylinder (forming a line), and the piston 8 of countercylinder passes to main crankshaft 1 through connecting rod 4, secondary crankshaft 2 and synchronizer 28, makes main crankshaft 1 obtain the power-assisted of secondary crankshaft 2; Two bent axles 1,2 rotate simultaneously and form makes a concerted effort; By main crankshaft 1 output, that is to say the air-breathing and oil inlet quantity with once, this link of blast working stroke that secondary cylinder system is equivalent to prolong motor through the present invention set up.Two cylinders 11,12 of adding one group of cylinder carry out exhaust simultaneously; The negative work phenomenon of exhaust has obtained effective improvement; Therefore most useful poweies has obtained sufficient utilization; Make power, the efficient of motor realize maximization, the discharge amount of tail gas reduces to some extent, and discharge quality increases.
Eight-stroke engine; Form by the four-stroke system of master cylinder and the four-stroke system of the countercylinder of correspondence, comprise bent axle 1,2, connecting rod 3,4; Piston 7,8 and cylinder 11,12 assemblies; Air-breathing door 21, exhaust valve 22,26, UNICOM's valve 24 is combined into the complete eight-stroke engine machine system of a cover with breathing valve 25 assemblies and cooling system and lubricating system etc.Have only master cylinder 11 to be provided with igniting and confession fuel assembly, each master cylinder 11 forms to interconnect through UNICOM's air flue 23 with corresponding countercylinder 12 and is referred to as one group, and UNICOM's air flue 23 is provided with UNICOM's valve 24 and opens and closes by the working procedure of setting with mortor operated valve 27.Master cylinder 11 is connected with secondary crankshaft 2 with main crankshaft 1 respectively through connecting rod 3,4 with corresponding countercylinder 12 interior pistons 7,8; Be provided with synchronizer 28 between two bent axle 1,2 one or both ends; Engagement through synchronizer 28 makes 1,2 whiles of two bent axles, speed, rotation in the same way together; Two pistons 7,8 in when acting blast one group of cylinder make two bent axles 1,2 produce rotation simultaneously and form through connecting rod 3,4 and make a concerted effort, and carry out power by bent axle 1 and export.The master cylinder system is with air-breathing, compression, blast, exhaust stroke work; The countercylinder system presses: air-breathing, exhaust, blast, exhaust stroke work.
UNICOM's valve 24 can be opened when the blast acting correct time, and the 1-5ms that more can lag behind opens.Main crankshaft 1 can turn round with angle with secondary crankshaft 2 simultaneously, also can form 0-an angle of 90 degrees and rotate simultaneously.Arranged between the time of opening of UNICOM's valve 24 and the angle of swing of secondary crankshaft 2 a best match time.
Working state and the function of each valve in air-breathing, compression, blast, exhaust process:
Breathing process: two pistons simultaneously by top dead center when lower dead center is moved, air-breathing door 21 is opened and is carried out air-breathing and oil-feed, exhaust valve 22,26, UNICOM's valve 24 are closed, and breathe valve 25 and open.
Compression process: two pistons simultaneously by lower dead center when top dead center moves, air-breathing door 21, exhaust valve 22,26, UNICOM's valve 24 are closed, and breathe valve 25 and open.
The igniting blast process: two pistons simultaneously by top dead center when lower dead center is moved, UNICOM's valve 24 is opened, air-breathing door 21, exhaust valve 22,26 are breathed valve 25 and are closed.
