Description

Compound rotary internal-combustion engine

The utility model relates to the rotary piston internal-combustion engine that a kind of combined rotary type IC engine is particularly made up side by side by acting cylinder and distribution cylinder.

In the reciprocating IC engine in the past, promote bent axle by piston by connecting rod and rotate, impact force is big, complex structure, and energy conversion efficiency is low.In rotary engine, the heat energy of fuel is directly changed into mechanical rotation power, Chinese patent CN85105592A is the wheeled rotary engine of biconvex, the phase that rotates a circle, the interior inflammable gas that sucks was no more than 2/3 of its whole working spaces, its compression ratio is uncontrollable, adopt the inner air cooling of rotating piston, cylinder body can't cool off.U.S. Pat 3,810,724 is single cam type rotary engine, cam does not have back bevel, and push rod backhaul impact force is big, and air inlet control is made up of one group of sprocket wheel, chain, little cam and axle, the valve controling rod of being with spring, valve, valve etc., complex structure does not have cooling unit.Two mixed gass that rotary engine enters from suction port, non-intensified concentrates, and it is little to fire power, and power is lower.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, before the air inlet of acting cylinder, provide concentrated pressure mixed gas and provide a kind of with the distribution cylinder, strengthen the power that fires, improve power, parts are concentric circle, simple in structurely easily make, and volume is little, and can improve the compression ratio of acting in the cylinder, increase efficiency of heat engine.

Combined rotary type IC engine is made up of round water jacket, circular cylinder body, spark plug, convex piece, annular piston and slider, and circular cylinder body comprises acting cylinder and concentric with it alternate being connected as a single entity of distribution cylinder arranged side by side.Induction chamber sucks outside oil and AIR MIXTURES during distribution cylinder piston rotation, gasified, compress by pressing chamber then, when volume is reduced to long-pending about 1/9 time (this moment, temperature was near its burning-point) of full cylinder body, convex piece front bevel upper channel mouth bottom overlaps with gas storage storehouse gas collection hole just, and the high pressure combustible gas is pressed in the gas storage storehouse; Piston rotation in the acting cylinder, when convex piece back bevel breaks away from slider, back bevel upper channel mouth bottom air vent lucky and on the storage vapour storehouse overlaps, the high pressure combustible gas pours in the firing chamber, when turning over a small angle, staggering in two holes, (the long-pending ratio with combustion chamber volume of full cylinder body this moment is exactly a compression ratio, can adopt the way of this angle of control to increase substantially ratio, as make its reach 20:1 or 30:1 all can, and don't reduce the pressure and the concentration of combustible gas in the firing chamber, thus the raising efficiency of heat engine), slow slightly, plug ignition fires, and pressurized gas promptly promote the convex piece and drive the spindle piston rotation, finish air-breathing, compression, fire, exhaust four processes.This internal-combustion engine working application time of phase weekly is 3/4T.All the other 1/4 times (amounting to the corner of pi/2) were used for steam discharge, admission, passed through slider, so its output power is bigger in acting the time that is one week interior 3/4.

Combined rotary type IC engine is equipped with rotary-piston in it, there are 3 convexs packaged in the acting cylinder on the rotary-piston, 2 packaged phase positions in the distribution cylinder of convex, rotary-piston central bore wall is with fixing storage vapour storehouse, two inclined-planes before and after the convex piece in the acting cylinder, synthesize trapezoid shaped with upper and lower surface, and tighten together with the rotary-piston outer surface, back bevel perforate road is connected with company's wall center-aisle of annular piston.The inclined-plane, front and back of convex piece and end face and batching pig end face during rotation, the part contact is slided; Convex piece front bevel perforate road in the distribution cylinder is connected with the duct, inside that annular piston connects wall, and all the other are identical with acting cylinder camber block structure.3 annular pistons of acting cylinder helix direction vertically evenly distribute, and piston inside and outside ring body and function piston connects wall and is connected, and 2 annular pistons of distribution cylinder are positioned at and the coaxial relative position of acting piston.Warehouse is a cylindrical shape, is positioned at annular piston inwall center portion, is fixed on the body motionless, totally 5 of rectangular holes are arranged on the shell of gas storage storehouse, wherein 3 corresponding with acting cylinder camber piece lower channel opening, this hole is positioned at the slider center line to the less angle of a side of spark plug, linear array; In addition 2 corresponding with distribution cylinder camber piece lower channel opening, be positioned at the slider center line to a side of exhaust passage than linear array on the mitre.

Slider slipping block section up and down is a rectangular, in its groove spring is housed, and the lower-left end is equipped with roller bearing, and the acting cylinder is equipped with spark plug near its right side, and the distribution cylinder is equipped with the import of carburetion gas.Circular cylinder body has circulation water channel outward.Acting cylinder, distribution cylinder, rotary-piston and gas storage storehouse are concentric circle.The gas storage storehouse is encapsulated in the rotary-piston inwall, and left end is fixed on the body, and rotary-piston right-hand member and internal combustion engine shaft are connected as a single entity, and rotate.Outside the gas storage storehouse from the admission of distribution cylinder camber piece lower channel opening to gas storage storehouse rectangular hole, and by gas storage storehouse process and the corresponding rectangular hole of acting cylinder camber piece lower channel opening, air feed carries out each other simultaneously to acting in-cylinder combustion chamber, to increase mixed gas pressure intensity.The utility model is the internal-combustion engine of working in this way.This machine adopts the two water routes of import and export circulation water channel inner cold system to cool off.

Its advantageous effect of combined rotary type IC engine of the present utility model is as follows:

A, thermal efficiency height: this machine is in the acting cylinder, and the expansion chamber volume can transfer to very big (being that compression ratio is very big) with the ratio of combustion volume, so can increase substantially efficiency of heat engine.

B, power are big: this machine weekly the time of phase acting be 3/4T, output power is bigger; The mixed gas that enters acting cylinder firing chamber from the gas storage storehouse is concentrated through the pressurization of distribution cylinder, and it is strong to fire power, and power is big.

C, simple in structure, volume is little: this machine motion parts is coaxial rotation in the same way, and standing part round water jacket, circular cylinder body, gas storage storehouse are all at coaxial position.Gas supply mechanism is compared with existing internal-combustion engine and is simplified greatly.This machine structure only is that the contraposition in hole opens and closes, so mechanical parts significantly reduce, simple in structure, volume is little, and is easy to process.

D, cooling be rationally: this machine has adopted two water route intercooling cycle system.All fixing around the fuel chamber and rotating part are cooled off simultaneously, reduced heat resistance requirement material.

This machine is suitable for the extensive use of field of internal combustion engine, by repacking a little, also can be used as diesel engine and steam engine and uses.This machine compact structure, easy processing, cheap, be suitable for and promote the use of.
