Embodiment

Further specify the present invention with enforcement in conjunction with the accompanying drawings, accumulative type engine of the present invention is to having now into, press, quick-fried, arranging four strokes is the improvement that a work cycle is finished the explosive motor of external acting, on the basis of existing cylinder, countercylinder and accumulator are set, working condition is that air inlet and compression stroke are with existing motor, when explosion stroke (accumulation of energy stroke just) is worked, piston 3 is descending under the promotion of high temperature and high pressure gas, drive externally acting of bent axle 5 rotations by connecting rod 4, when bent axle 5 connecting rods 4 rotate to the exhaust advance angle position, squish door 12 is opened, high temperature, (the existing motor of this part gas enters in the atmosphere as waste gas pressurized gas in vain, pollute with exhaust noise big) be pressed into rapidly in the main accumulator 6, it is up to promote piston 8, compress 10 accumulation of energys of main accumulator 6 springs, and the incomplete gas that burns burns away, energy further strengthens, main accumulator 6 springs 10 are further compressed, when the left and right sides are spent in bent axle 5 continuation rotations about 30, squish door 12 is closed, exhaust valve 13 is opened after a while, inferior high temperature and high pressure gas is pressed into rapidly in the secondary accumulator 7 through one-way valve 19, pressure spring 11 stored energy, bent axle 5 continues to rotate forward about about 30 degree, exhaust valve 14 is opened, because pressure reduction, one-way valve 19 is closed simultaneously automatically, the waste gas that the decrease temperature and pressure amplitude is very big is arranged after master cylinder 1 air outlet flue 20 enters the baffler damping to atmosphere, major-minor accumulator 6,7 at piston 8, during 9 up-downgoings, the air of piston top big vent hole and the atmospheric pressure in the air filter through the top rapidly keeps balance, and can not hinder the up-downgoing of piston.

Cause is continuously to the master, secondary accumulator 6, inflation in 7, row has not had very macro-energy to the gas of baffler, row has the very big range of decrease to the more existing motor of the noise of atmosphere after the noise reduction damping, simultaneously, at squish door 12 open positions to having sufficient time to allow unburned gas perfect combustion completely between exhaust valve 14 is opened, be pressed into the master, secondary accumulator 6, the time that high temperature and high pressure gas in 7 exists is longer, more can perfect combustion, so, major-minor cylinder 1, the carbon monoxide of the discharging of the 2 final more existing motors of waste gas of discharging, hydrocarbons content can significantly reduce, and has realized low emission.

Because driving bent axle 5, the energy storage effect of flywheel in explosion stroke, inertial force continue to rotate into forward next exhaust stroke.

At this moment, piston 3 is up to last fulcrum by lower fulcrum, the waste gas in the master cylinder 1 is thoroughly arranged after the baffler damping to atmosphere to master cylinder 1 air outlet flue 20 by way of exhaust valve 13, exhaust valve 14 rows, and the same reason, this part exhaust gas discharging and noise are significantly to reduce equally.

The air flue that master cylinder 1 one side intake valves 15 connect is straight air flue and connects the arc air flue, between an end of arc air flue and the straight air flue intake valve 17 is set.

When entering suction cold punching journey, intake valve 17 is opened, in fact can when last one-stroke, just open ahead of time, this valve passage leads to air-strainer after walking around closure 16, purpose is in this stroke and following one-stroke, avoid increasing, exhaust resistance, consumption of engine power, simultaneously, intake valve 15 is opened, because intake advance angle is arranged, actual just opened at last one-stroke end, at this moment, the not oil spout of petrol engine EFI formula ECU (Electrical Control Unit) control EFI mouth, the not oil spout of diesel electric-controlled or mechanical control oil nozzle, the motor of Carburetor is installed because opening of intake valve 17, no air flows at a high speed, flow out closure 16, oil nozzle does not have fuel oil and is sucked out, at this moment, piston 3 by top dead center to the descending vacuum that forms of lower dead center, the cool air of suction after the air-strainer filtering (center housing temperature relatively) and enter down one-stroke, the heat radiation stroke, simultaneously, secondary cylinder 2 intake valves 21 are opened, inferior high temperature and high pressure gas in the secondary accumulator 7 rushes at secondary cylinder 2 pistons 22 tops through intake valve 21, and promotion piston 22 is descending by connecting rod 23 drive bent axles, 24 rotation actings (can be used to generating to battery charging), when the arrival lower dead center is neighbouring, exhaust valve 18 is opened, waste gas is arranged in atmosphere after secondary cylinder 2 air outlet flues 25 rows advance the baffler damping, also the same reason, and this part exhaust gas discharging and noise are also very low, its work cycle is one week of crankshaft rotating, advances, exhaust, piston is back and forth respectively once finished a work cycle (can be with single cylinder engine, multi-cylinder engine formation existence) no longer tells about below.

When master cylinder 1 enters the heat radiation stroke, piston 3 is up to top dead center by lower dead center, the hot air that absorbs center housing temperature is led to air-strainer through intake valve 15, intake valve 17, so both cooled off master cylinder 1, prevent engine overheat, again preheating the air in the air-strainer, when making next aspirating stroke air inlet, fuel-oil atmozation is better, and it is more complete to burn, velocity of combustion is faster, and power is more powerful.

Successively, be the exoergic stroke below, at this moment, squish door 12 in the main accumulator 6 is opened, high temperature and high pressure gas in the main accumulator 6 rushes at master cylinder 1 piston 3 tops rapidly by squish door 12, it is descending to promote piston 3, drive externally acting of bent axle 5 rotations by connecting rod 4, when bent axle 5 connecting rods 4 rotate to the exhaust advance angle position, exhaust valve 13 is opened, as the gas pressure in the secondary accumulator 7 less than exhaust pressure in the master cylinder 1, gas unidirectional valve 19 in the secondary accumulator 7 can be backed down, and the inferior high temperature and high pressure gas that master cylinder 1 is discharged can enter in the secondary accumulator 7 and compensate, and continues from the exhaust advance angle position about about 30 degree of rotation at bent axle 5 connecting rods 4, outlet valve 14 is opened, because pressure reduction, one-way valve 19 can be closed automatically, and the waste gas of discharging from master cylinder 1 is arranged after master cylinder 1 air outlet flue 20 enters the baffler damping to atmosphere, in like manner, this part exhaust gas discharging and noise are also very low.

Bent axle 5 continues rotation, by being advanced into exhaust stroke on the connecting rod 4 drive pistons 3, waste gas is thoroughly arranged after the baffler damping to atmosphere to master cylinder 1 air outlet flue 20 by way of exhaust valve 13, exhaust valve 14 rows, or the same reason, this part exhaust gas discharging and noise also are very low, so far, work cycle of this accumulative type engine finishes (all waste gases discharging can shared baffler row to atmosphere).

In sum, this accumulative type engine is an aspirating stroke, compression stroke, explosion stroke (accumulation of energy stroke), exhaust stroke, inhale the cold punching journey, the heat radiation stroke, the exoergic stroke, exhaust stroke, eight strokes are finished a work cycle, wherein, the exoergic expansion stroke is that existing motor is unexistent, existing motor drains into this part energy in the atmosphere in vain, and pollute atmosphere and exhaust noise is big, that is to say same acting number of times, this accumulative type engine thermal efficiency theoretically is doubled, oil consumption and discharging are half of existing motor, exhaust noise is littler, consider and work the more complete and secondary cylinder 2 of burning (secondary cylinder working does not consume master motor energy and power, existing motor, generator takies engine power, cause the loss of the big and power of oil consumption), in addition, the heat radiation stroke of this accumulative type engine hinders piston stroking upward unlike existing engine compresses stroke, consumption of engine power, so, this accumulative type engine practical oil consumption and discharging may be lower, the thermal efficiency is higher, as needs, can repeat exoergic stroke and exhaust stroke, make oil consumption lower, discharging is desirable more, but will turn to cost to sacrifice power and distribution device complexity.

This accumulative type engine can a cylinder one major and minor accumulator when multi-cylinder uses, but also multi-cylinder shared one big major-minor accumulator, but each air flue should shorten as far as possible, to reduce energy loss (secondary cylinder can be used single cylinder, also available multi-cylinder form).

The secondary cylinder 2 of this accumulative type engine can be used to generating to charge in batteries, do not accounting for master motor power, not under the situation of consumes energy (comparing) with existing motor, use the useless energy (master motor relatively) of discharging in the master cylinder 1 to do power source, so compare with existing motor, this accumulative type engine load is lighter, and (existing engine power generation takies engine power, cause the loss of the big and power of oil consumption), moreover the heat radiation stroke hinders piston stroking upward, consumption of engine power unlike existing engine compresses stroke, in addition, because inhale the heat exchange of cold punching journey and heat radiation stroke, motor is difficult for overheated, longer service life.Simultaneously, because changeable one-tenth electric drive, this partly the existing relatively motor of electric energy be consumes energy not, do not take power and gratuitously additionally obtain, making needs the energy of engine operation acting to be saved originally, wearing and tearing are minimized, also for this accumulative type engine lengthen the life and consumption reduction has been made contribution! In addition, increase master cylinder 1 engine power as need, the air intake pressurized accumulator of optional dress such as accompanying drawing, the air intake pressurized accumulator is by cylinder 26, piston 27 in the cylinder 26, spring 28, one-way valve 30, throttle valve 31 constitutes, one-way valve 30, throttle valve 31 is fixedly installed on the inner bottom part of cylinder 26, one-way valve 30 is connected through the big vent hole of pipeline with main accumulator 6 tops, also be provided with the breeches pipe road on the pipeline that one-way valve 30 connects, the entrance point in breeches pipe road is provided with one-way valve 29, the pipeline that connects air-strainer at one-way valve 29 another termination cylinder 26 tops of control, throttle valve 31 meets intake duct closure 16 places of master cylinder 1 through pipeline, its working procedure is: main accumulator 6 is up after charging into high temperature and high pressure gas, the hot air through the air-strainer filtration of piston 8 tops, this place's air is by main accumulator 6 preheatings, by one-way valve 30, be pressed into rapidly in the air-admission pressure-booster, it is up to promote piston 27, pressure spring 28, hot air is stored in the cylinder 26 of piston 27 belows, this spring hardness is less than the master far away, secondary accumulator spring hardness, when motor is in aspirating stroke, ECU (Electrical Control Unit) is according to the motor needs, by the control throttle valve opening, regulate charge flow rate, at this moment, the hot air of former storage in the air intake pressurized accumulator, under the pressure of spring 28, by piston 27 pressurizations, rapidly from throttle valve 31 through gas-entered passageway, after mixing, the vaporific fuel oil of closure 16 and oil nozzle ejection is pressed in the master cylinder 1, owing to be to be pressed into rather than to be inhaled into, so just can make more inflammable mixture be full of cylinder 1 quickly, velocity of combustion is accelerated, it is descending that explosive force promotes piston 3 biglyyer, drive externally acting of bent axle 5 rotations by connecting rod 4, make engine power that very big increase be arranged on former basis.This air intake pressurized accumulator is applicable to petrol engine, diesel engine.In a word, this accumulative type engine is to realize low consumption, low row when electronic (zero-emission) low noise, low-heat, Gao Gong, long-lived, but fuel oil, combustion gas, petrol engine, diesel engine all are suitable for, novel power source that can mechanical, electrical two-way switching, can be described as the revolution on the motor history, can create huge economic and social benefit, to energy-saving and cost-reducing, environmental protection with adhere to the Scientific Outlook on Development, the harmonious society that builds together is of far-reaching significance great.
