Description

Adiabatic internal-combustion engine

The utility model relates to a kind of internal-combustion engine, particularly a kind of adiabatic internal-combustion engine.

At present to remain traditional be a working cell with a cylinder to the adiabatic internal-combustion engine (diesel engine) of exploitation, it exists very big problem, mainly contain 4 points: 1, present adiabatic machine-heating load is quite big, to such an extent as to reliability of material is poor, excessive discharge temperature, wall temperature is too high, the influence inflation, and the pressurized gas temperature is too high, worsens burning; 2, at present the ceramic diesel engine of exploitation is the same with traditional cooling type diesel engine is constant volume and the circulation of level pressure Hybrid Heating, and the thermal efficiency is not high; 3, owing to the restriction of Heating Cyclic and structure, rate of heat release is not too reasonable, and most of peak heat release moves down in the process at piston, and the merit of utilization is less; If most heat energy is when piston top dead center discharges, can cause overpressure to produce the engine knock accident again; When 4, present adiabatic machine utilizes energy in the exhaust all is to utilize power turbine to reclaim, and utilization ratio is too low, and cost is too high.

The purpose of this utility model is to propose a kind of adiabatic internal-combustion engine that can address the above problem.The purpose of this utility model is achieved in that a kind of insulation internal-combustion engine, comprise cylinder, cylinder head, piston, connecting rod, bent axle, valve, spark plug, oil sprayer and oil feed pump, cylinder head is covered hermetically on cylinder, piston is arranged in the cylinder, bent axle links to each other with piston by connecting rod, cylinder head is provided with valve, be set side by side with an auxilliary cylinder in cylinder one side, be provided with auxilliary piston in the auxilliary cylinder, auxilliary bent axle and auxilliary connecting rod, bent axle links to each other with auxilliary bent axle and synchronous working, driving piston and auxilliary piston by connecting rod and auxilliary connecting rod synchronouss working to top dead center and lower dead center in cylinder and auxilliary cylinder, be provided with passage in the cylinder head, owing to cylinder and the interior different compression swirls that produce of compression ratio of auxilliary cylinder, cylinder, auxilliary cylinder, cylinder head, piston, auxilliary piston, valve is made by thermoinsulation material.

The utility model has the advantages that: be applicable to two-stroke, quartastroke engines such as petrol engine, diesel engine, gas engine, be more suitable for the internal-combustion engine in supercharging mode, it relatively is the progress of a leap that this and present adiabatic machine can only be used on the four-cycle diesel; The compression ratio of adiabatic petrol engine can suitably increase in addition, shakes because of there being the enough big bags needn't consider that detonation is quick-fried, and the thermal efficiency can increase greatly.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is an air cylinder head structure schematic representation of the present utility model;

Fig. 4 is A-A sectional view of Fig. 3;

Fig. 5 is the multichannel sectional view in Fig. 3 cylinder head.

Insulation internal-combustion engine shown in Fig. 1-5, comprise cylinder 1, cylinder head 2, piston 3, connecting rod 4, bent axle 5, valve 6, spark plug 7, oil sprayer 8 and oil feed pump 9, cylinder head 2 is covered hermetically on cylinder 1, piston 3 is arranged in the cylinder 1, bent axle 5 links to each other with piston 3 by connecting rod 4, cylinder head 2 is provided with valve 6, be set side by side with an auxilliary cylinder 11 in cylinder 1 one sides, be provided with auxilliary piston 13 in the auxilliary cylinder 11, auxilliary bent axle 15 and auxilliary connecting rod 14, bent axle 5 is connected as a body with auxilliary bent axle 15 and synchronouss working, driving pistons 3 and auxilliary piston 13 by connecting rod 4 and auxilliary connecting rod 14 synchronouss working to top dead center and lower dead center in cylinder 1 and auxilliary cylinder 11, be provided with path 10 in the cylinder head 2, owing to the different compression swirls that produce of compression ratio in cylinder 1 and the auxilliary cylinder 11, cylinder 1, auxilliary cylinder 11, cylinder head 2, piston 3, auxilliary piston 13, valve 6 is made by thermoinsulation material.Cylinder 1 is arranged side by side with auxilliary cylinder 11, and cylinder 1 is synchronoused working with auxilliary piston 13 with the piston 3 in the auxilliary cylinder 11, and cylinder 1 is main combustion cylinder, and auxilliary cylinder 11 is secondary combustion cylinder, and secondary combustion cylinder can be bigger than main combustion cylinder, also can make equally big; Piston 3 is air-breathing simultaneously by bent axles 5 with auxilliary 13 whiles of piston as shown in Figure 1, auxilliary bent axle 15 and connecting rod 4, auxilliary connecting rod 14 compresses simultaneously, because the compression ratio in the secondary combustion cylinder is bigger than the compression ratio in the main combustion cylinder, pressure is also than big in the main combustion cylinder, so the portion of air in the secondary combustion cylinder enters main combustion cylinder by path 10, form strong a plurality of compression swirls, in the time of near piston 3 is compressed to by top dead center, on injection advance angle, as Fig. 2, oil sprayer 8 beginning injected fuel, and in main combustion cylinder, form mixed oil and gas, again when bent axle 5 turns over injection advance angle and forwards ignition advance angle to, as Fig. 1,3, four spark plug 7 beginnings igniting simultaneously, in main combustion cylinder, form quick sequential combustion, at this moment the gas pressure in the main combustion cylinder rises rapidly, high-pressure gas enters secondary combustion cylinder by a plurality of path 10s in the mode of pulse, the combustion cylinder is become owner of in portion of air punching press in the pair combustion cylinder, and in two cylinders, form strong eddy current, promote heat to mix, promote fuel oil rapid combustion and in two cylinders, distribute heat energy, expansion ratio heightens, the thermal efficiency is heightened, the heat load of adiabatic machine has also reduced widely simultaneously, reliability and life-span have also improved, though two interior mean effective pressures of cylinder have all descended some, but the acting area has but increased exponentially, moment of torsion generally speaking is to have increased, the heat release form of this adiabatic machine is that heat almost is to discharge when the Piston Compression top dead center quickly, approximate constant volume Heating Cyclic is because there is the space of two firing chambers, so can not produce too high pressure, and temperature is also lower, carbon granule, HC, NO, NO _xQuite low Deng discharging, the excess air factor in the main combustion cylinder is to be suitable for the excess air factor of rapid combustion and definite according to gasoline and diesel oil.The burning principle of this adiabatic machine is: mixed gas igniting fast in main combustion chamber (open type) as much as possible, sequential combustion (near the mixed gas the passway is burning earlier), enter subsidiary combustion chamber (open type) by passage again after the finishing combustion, if the unburnt mixed gas of small part enters subsidiary combustion chamber, that is just lighted a fire again by two spark plugs in subsidiary combustion chamber again and burns away.
