Exhaust valve component 5 is outlet valve 51, high-temperature heat exchanger multifunctional module, comprises assembly overcoat 59, outlet valve 51, outlet valve circle 52, guide pin bushing 55 and heat-exchanging fin for heat-exchanger 510.Exhaust valve component 5 places the top of A cylinder 31 and D cylinder 34, the inside of cylinder head 4.

Be provided with upper mounting plate 57 and lower installation board 54 between the last positioning plate 58 of guide pin bushing 55 and the following positioning plate 53, be provided with double helix heat exchange steam pipe 56 between upper mounting plate 57 and the lower installation board 54.

Fig. 2 is an I portion enlarged diagram among Fig. 1, and exhaust valve component 5 comprises outlet valve 51, outlet valve circle 52 and guide pin bushing 55, and outlet passageway 28 and gas-entered passageway 29 are located in the exhaust valve component 5.

The cylinder cap of A cylinder 31 and D cylinder 34 is provided with UNICOM's air valve 6, is respectively applied for control A, B, the break-make of D, C cylinder.Bent axle 1 crank throw angle is 4 * 90 ° of four-cylinder usually, but adopt 0 ° (shown in Figure 4) ,-30 ° (shown in Figure 5), 150 ° (shown in Figure 6), the mode of 180 ° (shown in Figure 7).Turning with A is 0 °, and then B, C, D turn and be respectively-30 °, 150 °, 180 °.With the rotation of diagram bent axle 1 clockwise direction, A cylinder 31 and D cylinder 34 leading B cylinders 32 and C cylinder 33 arrive piston 4 top dead centers when being 30 °.33 in B cylinder 32 and C cylinder are finished suction, are pressed stroke, and the mixed gas after will compressing by UNICOM's air valve 6 is respectively sent into A cylinder 31 and D cylinder 34.34 liang of cylinders of A cylinder 31 and D cylinder are only finished combustion, row's stroke, realize that compression ignite separates, its consequence clearly, heat is concentrated to A cylinder 31 and 34 liang of cylinders of D cylinder.Below be concrete working principle:

When A cylinder 31 pistons 4 arrival top dead centers, end exhaust stroke, exhaust valve component 5 is closed.This moment, B cylinder 32 pistons 4 were positioned at-30 degree positions, and compression stroke closes to an end.Because B cylinder 32 " firing chamber " volume is " zero " substantially, the compression ratio of this position mixed gas is about 7.6: 1 greater than the compression ratio of conventional engine.Open UNICOM's air valve 6 this moment, and B cylinder 32 pistons 4 continue to move upward, and A cylinder 31 pistons 4 begin to move downward, because UNICOM's air valve 6 is opened, compressed mixed gas can enter A cylinder 31 smoothly.Because B cylinder 32 volume reduction rate are greater than A cylinder 31 volume increment rates, mixed gas continues to be compressed.When A cylinder 31 and B cylinder 32 reached 15 degree and-15 respectively and spend, two cylinder rate of volumetric changes equated (opposite in sign), and mixed gas reaches maximum compression ratio, and the cylinder pressure is the highest.Can appropriate change A cylinder 31 pistons 4 top shapes, form certain " firing chamber " space, in order to adjust compression ratio.Before and after this, the igniting of can selecting a good opportunity.Piston 4 continues operation, closes UNICOM's air valve 6 when B cylinder 32 pistons 4 reach after top dead center, mixed gas all enter A cylinder 31.B cylinder 32 pistons, 4 beginnings operation downwards enters suction stroke.A cylinder 31 pistons 4 continue operation downwards, finish combustion stroke.

Analyze common four stroke engine, in the four-stroke, the heating of compression ignite two strokes wherein mainly is a combustion stroke.Though exhaust stroke is not generated heat, also be unlikely to cooling.Have suction stroke only, countercylinder is a cool down, but the gas to sucking but is a process that heats up continuously.Before suction valve cut out, gas in the jar had reached certain temperature.After suction valve cut out, the gas in the jar gross mass was fewer than cold conditions.The gas-entered passageway that temperature is lower helps sucking more gas.And burning needs higher temperature, and this divides in the cylinder at compression ignite contradiction and is solved preferably: the combustion row cylinder that suction cylinder pressure that temperature is lower and temperature are higher.

Because gas is unconfinedly to be compressed, all common engine must leave the gas after certain volume is deposited compression when the piston arrives top dead center, be called " combustion chamber volume ", the utility model is no exception, only borrows the space of adjacent cylinder to do firing chamber usefulness.For inhaling cylinder pressure, corresponding volume is the smaller the better.As long as selection and measure are appropriate, can satisfy even be better than the combustion condition of common engine fully.And because the crank throw of adjacent combustion row cylinder has turned over several angle, better for the motor stress condition, the performance of more favourable raising motor.For burning, because the raising that cylinder volume is advanced the speed makes the interior High Temperature High Pressure time shortening of cylinder, angle move forward, but might not influence the completeness of burning, because whether burning does not all depend on the High Temperature High Pressure of short time fully.

In fact the utility model is four cylinders, six valve arrangements, and common relatively four cylinders, 16 valves are simple, but big many of inlet and outlet effective drift diameter.

The basic structure of motor is simple than common engine, inhales cylinder pressure suction tude EFI fuel feeding, throttle adjustment air inflow, cylinder head configuration major diameter suction valve.Inhale between cylinder pressure and the combustion row cylinder and establish the minor diameter coupling cock.Combustion row cylinder configuration discharge means and ignition mechanism.Desired configuration is to inhale cylinder pressure configuration lift variable electronic suction valve+ignition mechanism, combustion row cylinder oil directly spray device, make motor have variable compression ratio, controlled burning function, be that motor adopts ignition way when startup, low speed and high speed, adopt the compression ignite mode during middling speed, further improve the efficient and the fuel economy of motor.Even can accomplish that vapour, diesel oil are general.

Collect that part of heat of discharging simply, efficiently, be used to make part water to become uniform temperature is arranged, the steam of pressure, drive the miniature steam turbine unit, become second power source of motor with it with exhaust.Obviously, from eight little outlet valves of four cylinders, reclaim heat energy,, the many, inefficient many of difficulty than from two atmos-valves of two cylinders, reclaiming heat energy.This part can be divided into two fractions:

1, " boiler " part: the high-temp waste gas with discharging, become an amount of high temperature and high pressure steam and the waste gas of lower temperature, use for the back level.This part is by water pump 12, preheating water pipe 18, and vapour, water flow control/Temperature Detector 17, exhaust valve component 5, discharge means cross over pipe 26, discharge means connecting tube 25, slave parts such as high steam-pressing pump 13, condenser 11, water tank 10 are formed.Water pump 12 supplies water to A, D cylinder 31 and 34 preheating water pipes 18 respectively, is controlled by vapour, 17 pairs of water temperatures of water flow control/Temperature Detector and flow.The water that enters exhaust valve component 5 enters discharge means cross over pipe 26 respectively with the waste gas that still has uniform temperature and discharge means connecting tube 25 is further vaporized after first step vaporization, and reaches cryogenic overheating.Waste gas/steam separator 16 will drive waste gas, steam is derived steam driven steam turbine (steam turbine) 14 respectively after separating.Waste gas then drives exhaust turbine 15.The output of turbo machine is connected to engine output shaft, auxiliary power is provided through turbo machine-output shaft strap 22.Tail vapour behind the driving steam turbine still has uniform temperature, pressure, returns exhaust valve component 5 by high steam-pressing pump 13.

2, turbine/steam turbine part: in the system diagram, turbine/steam turbine set needs to mate integration with motor.

This part technology is not only applicable to petrol engine, equally is applicable to diesel engine yet.For rail traction on-board engines such as picture 16V280 and 16V240, then can directly adopt exhaust valve component transformation, can effectively improve the overall efficiency of motor.

In the dual media hybrid engine, water also as second medium, participates in the acting circulation by certain methods except that participating in cooling, become second power source.So be referred to as " dual media hybrid engine ".The utility model is according to existing industrialized production level, adopts mature technology, and around " second power source ", simplified structure adapts to the demand that large-scale industrialization is produced as far as possible.The utility model has improved the thermal efficiency of motor greatly, has saved the energy.

With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
