Abstract

The invention relates to an impeller blade type pressurization internal combustion engine that is using the combustion gas expanding caused by fuel burning in compressed air to pull the piston that sliding on the power output shaft. The piston is rotating in the rotundity cylinder and drives power output shaft to rotate. It is the internal combustion engine has the feature of plenumpiston. The engine is made up of cylinder, piston, power output shaft, air compressor. When the engine starts, the extra power would input into power output shaft to drive piston rotating in cylinder. And the air compressor compresses air into cylinder. The fuel nozzle near the air intake sprays fuel or fuel gas toward the compressed air to form mixed gas. The rotating piston compresses the mixed gas further to the highest pressure the machine designed and the spark plug fires the mixed gas to produce high temperature and high pressure gas to pull piston and drive power output shaft to rotate.

Description

The blade pump type boosting explosive motor

One, technical field: the blade pump type boosting explosive motor is to utilize fuel to burn in pressurized air, the expansion combustion gas that produces promotes sliding piston, rotation and drive pto rotate in a circular cylinder, and the gas internal-combustion engine with air intake pressurized characteristic belongs to the internal-combustion engine engineering technology.

Two, background technique: since the explosive motor invention, the research of internal-combustion engine is always around improving engine efficiency, reducing oil consumption, reduce to pollute, reduce volume and weight and carry out, but up to now, the Reciprocating engine piston of extensively making and using and the inertia problem of kinematic link, the complexity of inlet and outlet mechanism and power loss problem, triangle piston circulating engine sealing problem, reliability and expensive problem are not solved at all.

The present invention is a basic goal with the efficient that improves motor.Be approach mainly by the problem already pointed out that solves the available engine existence, take to allow piston directly drive output shaft and rotate, improve compression ratio and waste gas eliminating quality, and the simpler means of structure of motor are realized by gas compressor.Simultaneously, reach the reliable of motor, long service life.

Three, summary of the invention: motor of the present invention is made up of main members such as engine cylinder, piston, pto, gas compressors.Cylinder sideline nearly 2/3rds is a circular edges, and all the other limits are oval edges, the global approximation circle.There is cylinder cap the both sides of cylinder.Motor import external power by engine power output shaft when starting, and drives piston and rotates in cylinder, rotates by gear or the wheel band driving belt gas compressor of taking offence simultaneously.Gas compressor is pressed into cylinder with air, and by near the nozzle intake valve to the air jet fuel oil or the inflammable gas that are pressed into, form mixed gas.The piston of rotation is compressed to the maximum pressure that this machine designs further with mixed gas, and lighted mixed gas by plug ignition this moment, produces high temperature and high pressure gas, promotes piston and the directly rotation of drive pto, externally acting.

The existing explosive motor of contrast, the present invention has following difference and advantage:

1, efficient height.Compare with Reciprocating engine, the piston motion that designs because of the present invention almost is to turn round according to the center of circle of pto, and bigger reciprocal inertia does not exist for the problem that overcomes reciprocal inertia and more high-power loss is arranged; This invention does not have the inlet and outlet valve member, therefore, does not exist for and pushes valve open and the problem of wasted power; Piston of the present invention directly drives the pto acting, does not have complicated power-converting member, less friction loss; The present invention is when the cylinder exhaust, because relief opening is programmable bigger, when exhaust finished soon, exhaust gas pressure was little, so lack than the power loss of Reciprocating engine exhaust.Compare with triangle piston circulating engine, sealing can be done reliably, and supercharging becomes possibility.Therefore, on raising the efficiency, bigger potentiality are arranged.In addition, this motor is by adjusting the cylinder diameter size and can conveniently take the measure of air-cooled or small size oil cooling that the operating temperature in the combusted cylinder acting district of motor is carried out temperature adjusting, thus save power loss that the liquid cooling cylinder mechanism consumed and to manufacturing bring complicated.Once more, this motor is because of the characteristics and the position that can adjust cylinder diameter size and porting of its unidirectional rotation, make combustion gas controlled reason of expansion time in cylinder, can accomplish the delivery temperature of motor is controlled, to make full use of high-temperature gas heat energy, be used for acting to greatest extent.

2, simple structure, cost of production is low.Engine construction of the present invention is relative and Reciprocating engine is simple, and component are few.Main member has only cylinder, piston, Sealing, pto, gas compressor etc., no inlet and outlet valve mechanism, and no connecting rod, crankshaft system, manufacturing process is simple.With respect to triangle piston circulating engine, accuracy of manufacturing requires low, and cylinder processing is also simple than the epitrochoid shape cylinder processing of triangle piston circulating engine.In addition, Reciprocating engine and wankel engine increase power and improve smoothness, often take to increase the way of cylinder number, and this has increased the manufacture cost and the complexity of motor undoubtedly.And this motor can improve the power and the smoothness of motor by increasing the way of piston number in a cylinder, and therefore, cost is lower.

3, the low pollution.This motor is longer period of combustion in cylinder because of fuel, and fuel is fully burned, and is very favourable to the generation that reduces NOx therefore.Other pollute waste gas, and because of this motor has higher relatively efficient, polluting also can be relatively low.

Four, description of drawings:

Fig. 1 is the engine cylinder cross-sectional view.This figure has described the situation of cylinder block cross section, has reflected fuel nozzle, the position of spark plug and the layout in gas compressor and inlet and outlet road.Inlet and outlet mouth on the cylinder block is arranged to one.Be provided with airtight plate between intake duct and air outlet flue, airtight plate can rotate, and the power of its rotation comes from the discharge pressure of combustion gas and through the air of gas compressor supercharging.Its effect is: when airtight plate turned to relief opening, airtight plate blocked the major part of relief opening, and cylinder begins air inlet, and when airtight plate turned to suction port, airtight plate was blocked suction port, and the combustion gas in the cylinder after the acting begins outwards to get rid of by air outlet flue.

Fig. 2 is engine piston horizontal stroke, longitudinal section, piston radial sealing parts figure.Piston is oblate Cylindrical object, and piston two tips have the semicircle groove that the radial seal member is installed.Radial seal is to be made of the semicircular pillar that an outside is surrounded by two spring sheets, and it is installed in the groove on the piston.In the time of when radial seal is together packed engine cylinder into piston in, under the tension force effect of spring sheet, can combine closely, and can be free to slide and in the piston mounting groove, rotate, play seal action along cylinder wall with cylinder wall and piston.Simultaneously, because of radial seal member and contacting of cylinder wall are the face contacts, also can play the effect that alleviates piston countercylinder wall pressure power.

Five, embodiment:

The blade pump type boosting explosive motor is when the position of arriving when piston operation as shown in Figure 5, it is maximum that the compression ratio of motor reaches, this moment plug ignition, compressed mixed gas ignites, piston is under the effect of expansion gaseous-pressure, and the axle center of moving power output shaft rotates under the constraint of cylinder wall and pto.Meanwhile, in the another side of piston, because most of combustion gas is discharged, the pressure of combustion gas is less than the air pressure of supercharging in intake duct, airtight plate is pushed to air outlet flue on one side, and compressed air begins to pour cylinder, and squeezes remaining combustion gas and discharge from the exhaust ports that stays.

When piston runs to as shown in Figure 6 position under the promotion of expansion combustion gas, combustion gas by porting to the air outlet flue exhaust, because of being in firm exhaust phase, the exhaust pressure of this moment is greater than the air pressure that is pressurized, therefore, airtight plate is pushed to intake duct and its mouth that leads to cylinder is blocked, and blocks entering of air.It is maximum that relief opening reaches at this moment, and combustion gas is discharged rapidly.Meanwhile, in the air compression district of the another side of piston, the air that entered just now is compressed, and fuel nozzle sprays fuel oil or other inflammable gass (as hydrogen, rock gas etc.) in pressurized air.
