Description

Compression conversion internal combustion engine

The utility model relates to internal-combustion engine, particularly a kind of compressing and converting formula internal-combustion engine.

Mostly existing internal-combustion engine is piston to-and-fro motion in cylinder block, and its efficient is low, generally can only reach about 30%.Recently occurred some rotary combustion engines successively, though the power ratio reciprocating internal combustion engine that unit volume produced is high by 60%, volume is little, in light weight, but slow-speed of revolution poor performance fuel consumption is big, and it is big to scrape pad wear, and particularly the eccentric shaking that produces between the internal tooth of rotor and the eccentric shaft is bigger.

The purpose of this utility model is a kind of New Rotary internal-combustion engine of design, makes it can overcome the shortcoming of above-mentioned reciprocating type and rotary combustion engine.

The purpose of this utility model realizes by the design proposal of following compressing and converting formula internal-combustion engine.It mainly is made of cylinder block, rotor, rotating shaft, blade, suction port and relief opening, inner chamber of cylinder block is eccentric 8 fonts, rotating shaft hollow, the groove that has three roads to communicate in the rotor in the rotating shaft with the axle center, adjacent grooves becomes 120 ° angle, have chute on the rotor at this angle middle part, being equipped with in the chute can be along the blade of chute slip; Cylinder body top, bottom internal chamber wall become lubrication and seal to contact with rotor, and inner chamber duct in casing wall in the left and right sides, bottom communicates; Spark plug is contained on the bottom left casing wall and communicates with inner chamber; The conversion valve is located on the casing wall of right side, bottom, and the break-make with control right side inner chamber and duct also is provided with a return-air groove on the inner chamber casing wall of right side, bottom.

Fig. 1 is the utility model structural representation, also is the working state schematic representation of rotor when being in a position; State when the state when Fig. 2 is in the b position for rotor, Fig. 3 are in the c position for rotor.

1, rotor, 2, rotor recesses, 3, rotor blade, 4, blade slide, 5, rotating shaft, 6, cylinder body, 7, the conversion valve, 8, spark plug, 9, the return-air groove, 10, the duct, 11, suction port, 12, relief opening.

Structure shown in the accompanying drawing also is embodiment of the present utility model, below in conjunction with accompanying drawing the utility model is further described.Its rotor recesses structure makes rotor have the effect of oil pump concurrently, machine oil enters rotor 1 by rotating shaft 5 and rotor recesses 2, and oil throws away to the rotor outer rim under centrifugal action during running, plays the effect of cooling and lubricating and sealing, then, get back to fuel tank through the oil outlet of former and later two end face outer rims of cylinder body; Its work done process is as follows: three blades are separated into 4 cavitys to cylinder respectively when rotor turns clockwise, and when rotor was in a position, cavity 1 was communicated with suction port 11, and oil gas enters, and cavity 2,3 is closed, and cavity 4 is communicated with relief opening 12; Turned round by a to the process of b position at rotor, cavity 1 is a suction stroke, the 2nd, and compression stroke, the conversion valve 7 that mixed oil and gas after the compression is opened thus the time automatically 10 enters work done cavity 3 through the duct, and when rotor rotated to the c position, compression finished, the conversion valve is closed automatically, spark plug 8 begins igniting simultaneously, and the burning work done of 3 chambeies promotes blade movement, 4 chambeies are exhaust strokes, when rotor turned round to a position by the c position, power stroke finished, and begins new circulation again.Rotor is rotation constantly in cylinder, by rotating shaft 5 mechanical energy that internal-combustion engine produces is outwards exported.The effect of return-air groove 9 is after the conversion valve-closing, remaining pressurized gas enters in the one circuit compression chamber of back by groove, with the back pressure of subduction, thereby improve the efficient of power stroke and prevent that the further compression of blade from making compression chamber produce spontaneous combustion blade.The conversion valve is provided with adjustable spring, so that as required, regulates the gas pressure size that makes the valve automatic on-off.

Advantage of the present utility model: 1. compact conformation, part are few, and volume is little in light weight. 2. easy to manufacture, raw materials consumption is few, and production cost is low. 3. the power height of working unit volume generation doubles than reciprocating internal combustion engine approximately. 4. be convenient to dismounting, maintenance is convenient. 5. owing to air-breathing, compression, work done, exhaust stroke are almost finished simultaneously, so shake little; The stroke of a circulation of reciprocating internal combustion engine can only be made merit one time, and the every circulation primary of the utility model just has three works done, can greatly improve rotating speed. 6. because rotor of the present utility model is piston is again oil pump, so can cancel the oil pump of internal combustion engine.
