Description

Double-acceleration combustion device for internal-combustion engine

The utility model relates to a kind of internal combustion engine burner, the two accelerated combustion devices of especially a kind of internal-combustion engine.

No matter the working principle by internal-combustion engine is that petrol engine or its groundwork situation of diesel engine are the same as can be known: each work cycle all will experience air inlet, compression, work done and four strokes of exhaust, wherein having only a stroke is work done, and its excess-three stroke all is the auxiliary stroke of consumed work.In each work cycle, two weeks of crankshaft rotating (720 °), each stroke has only half cycle (180 °), expansion space stroke (half cycle) is because the effect of expanding gas forces crankshaft rotating, three auxiliary strokes in all the other weeks half then rely on the inertia that is stored on the flywheel to rotate, and are that a work cycle is got ready.But because the power source of internal-combustion engine is all from atdc moment fuel oil explosive force, it is about 1/350 second of a used time of work cycle that the work done distance has only about 1/70 of total kilometres, power done time, and all the other times are negative work done.After a work cycle is finished, still there are emphatically about 1500 ℃ high temperature and 40 not works done of atmospheric heat energy in the cylinder and are after consumption of power, to be discharged, cause very big waste so the utilization ratio of heat energy is very low in the cylinder.Current techniques solution of the above problems one class is to transform from the structure of internal-combustion engine, and typical scheme is air inlet valve, exhaust valve to be moved to the cylinder casing loam cake respectively sentence the loss that reduces heat energy; Two classes are to improve the supply capability of internal-combustion engine oil supply system, and typical scheme is to improve to enter firing chamber fuel atomizing degree or directly add some combustion improvers to improve the ignition heat work doing efficiency in fuel.But, such scheme all is once to quicken the problem consideration of work done and taked relative measures at internal-combustion engine, and how utilizing of heat energy all do not give sufficient consideration after the work done, and it is low still to exist the internal-combustion engine heat power efficiency in the reality, the problem that heat energy loss is big.

The purpose of this utility model is to provide a kind of improved internal-combustion engine two accelerated combustion devices, and it can effectively utilize heat energy after the internal-combustion engine work done to improve efficiency of engine.

The purpose of this utility model is achieved in that the two accelerated combustion devices of a kind of internal-combustion engine, it comprises cylinder casing 1, cylinder chamber 2, cylinder casing loam cake 3, spark plug 4, piston 5, piston rod 6, crankshaft-flywheel 7, air inlet valve 8, air-outlet valve 9, it is characterized in that having a through hole 10 that communicates with cylinder chamber 2 and communicate the spray nozzle 12 that the other end and liquid-spraying pipe 1 join with cylinder chamber 2 at one one end of 10 mouthfuls of fastening installations of end of through hole in cylinder casing loam cake 3 upper ends.Described spray nozzle 12 is to cylinder chamber 2 hydrojets between preceding 15 ° of to top dead center back 40 ° of piston 5 work done top dead centers.When the expansion space stroke of internal-combustion engine forms the peak, by spray nozzle to combustor inner cylinder chamber atomizing of liquids with abundant absorption cylinder in heat produce vapor pressure and act on the piston that is subjected to the effect of former stroke gaseous-pressure, promote piston once more work done finish accelerated motion.

The utility model is opened a through hole and a spray nozzle is installed thereon because only need on the cylinder top head of internal-combustion engine, so structure is simple especially, because the starting point of the present utility model is to be placed on to make full use of on the heat energy that is produced in the former work done exhaust casing, therefore have the characteristics of accelerating piston work done once more simultaneously.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is the structure cut-away view that proposes according to the utility model;

Among the figure: the 1-cylinder casing; The 2-cylinder chamber; 3-cylinder casing loam cake; The 4-spark plug; The 5-piston; The 6-piston rod; The 7-crankshaft-flywheel; The 8-air inlet valve; The 9-air-outlet valve; The 10-through hole; The 11-spray nozzle; The 12-liquid-spraying pipe.

By Fig. 1, the utility model relates to the two accelerated combustion devices of a kind of internal-combustion engine, it comprises cylinder casing 1, cylinder chamber 2, cylinder casing loam cake 3, spark plug 4, piston 5, piston rod 6, crankshaft-flywheel 7, air inlet valve 8, air-outlet valve 9, it is characterized in that having a through hole 10 that communicates with cylinder chamber 2 in cylinder casing loam cake 3 upper ends and communicate with cylinder chamber 2 at one one end of 10 mouthfuls of fastening installations of end of through hole, spray nozzle 12 that the other end and liquid-spraying pipe 11 join.Described spray nozzle 12 is to cylinder chamber 2 hydrojets between preceding 15 ° of to top dead center back 40 ° of piston 5 work done top dead centers.First intake stroke when cylinder, second compression stroke is constant, when the 3rd expansion space stroke forms the peak, when just fuel acutely burns in cylinder chamber 2, spray nozzle 11 on the cylinder cover 3 sprays into highly pressurised liquid (as water) in cylinder chamber 2, liquid (as water) is subjected to violent the expansion and produces vapor tension and act on the piston 5 and make it descending in cylinder chamber 2, this moment, piston 5 one was the effect that is subjected to former gaseous-pressure, the 2nd, the pressure that is subjected to expansion of liquids gas quickens to finish third trip, and the gas that the fourth line journey is discharged then is the mixture of combustion gas and water vapour.Since spray nozzle 11 be between preceding 15 ° of to top dead center back 40 ° of piston 5 work done top dead centers to cylinder chamber 2 hydrojets, heat energy are fully utilized and have realized 5 pairs of purposes of quickening work done of piston in the piston 5 suffered dual descending pressure cylinders.

In addition to the implementation, the utility model also is suitable for the firing unit of diesel engine.The spray nozzle that the utility model adopted can be the employed fuel-injection valve for high-pressure of diesel engine cylinder, and the high-pressure water pump (not drawing on the figure) that supporting with it liquid-spraying pipe, liquid-spraying pipe are later and the cooling unit of inlet and outlet valve on the cylinder and motor and the method and the facility of their maintenance all can adopt existing known technology.
