Description

Single rotor internal combustion engine

Technical field the present invention relates to the combustion engine of rotary-piston type.

Background technique the applicant discloses a kind of two cylinders, one Room dual rotor internal combustion engine in the model utility of ZL99255833.6, general rotary engine has the big characteristics of working rotor angle, and therefore make exhaust pressure reduce to some extent, running noise greatly reduces, its main structure is that the relief opening and the pressurized machine of disjunctor rotor cylinder joined by pipeline, carry and press the power gas source of waste gas, obviously improved the gettering quantity of air compressing cylinder as the pressurized machine rotor.The spinning rotor of air compressing cylinder is finished air-breathing, compression process by the hyoplastron that leaf spring supports.Two rotors are provided with the pressurized moving plate that is symmetrical in detonation chamber spray row mouthful, and are meshing with each other by the little modulus gear teeth and reach the motive sealing purpose, and each rotor shaft is meshed with output shaft by gear.The synchronous cam that timing mechanism drove is transmitted in detonation and the spray row process that the middle and high door of calming the anger is finished the detonation chamber by two dynamic pressure plates, is provided with oil nozzle and spark plug in the firing chamber.

Described twin-tub one Room dual rotor internal combustion engine enters the practical stage, has the operation balance, and noise is low, the characteristics that working efficiency is higher, but double rotor and disjunctor cylinder structure thereof make structure comparatively complicated.

Summary of the invention the present invention is for solving the complicated practical problem of above-mentioned two cylinders, one Room dual rotor internal combustion engine structure, and a kind of simple in structure, one-spool engine that volume is less relatively is provided.

Comprise cylinder body, cylinder cap, air-strainer and pressurized machine in the technological scheme of the present invention, be connected to the pressurized machine power gas source pipe of relief opening, air compressing cylinder and spinning rotor, detonation chamber and oil nozzle and spark plug, timing mechanism and synchronous cam.The substantive structure of the present invention is: the spinning cylinder is to the air flue of detonation chamber, be provided with the middle pressure valve that constitutes by reciprocal valve rod and slideway thereof, the reciprocal middle pressure valve rise and the backhaul roller that engage respectively of valve rod setting and synchronous cam, the rotor cylinder cylinder body is provided with suction valve open in usual, the upper end-hole of the U-shaped air flue of its valve body is corresponding with detonation chamber spray row mouth, lower end mouth in the cylinder body is towards the rotor rotation direction, rotor basic circle surface is provided with the arcuation flange sections that suction valve cuts out, this flange sections matching gap with cylinder body is set along the rear end of rotor rotation direction, and have and advance institute's valve U-shaped air flue lower end mouth opposing end faces.

Its bottom of said suction valve is provided with the roller that engages with rotor basic circle and arcuation flange sections surface thereof.

The matching gap of said arcuation flange sections rear end and cylinder body is 0.01mm.

Said rotor cylinder, the set relief opening of its cylinder body is 35-50 ° with the axes intersect angular range of advancing institute's valve.

The present invention compares with two cylinders, one Room rotor internal-combustion engine has following outstanding advantage, and single rotor and housing structure thereof are simpler, have not only reduced processing cost, more are of value to reducing the whole internal-combustion engine volume.Suction valve has the control mechanism that is independent of middle pressure valve, makes operation easy to adjust more stable.The working rotor angle is more than 240 °, and toxic emission pressure is lower, and operational noise has further obviously reduction.The present invention rationally uses the detonation air-flow with expansion and mode of jet, and working efficiency is higher.

The present invention and twin-tub one Room rotor internal-combustion engine are listed as follows in following index contrast situation after tested:

Appended drawings 1 single rotor internal combustion engine structural profile schematic representation accompanying drawing 2 Figure 1A are to generalized section

Number in the figure: 1 rotor cylinder, 2 rotors, 3 relief openings, 4 power gas source pipes, 5 pressurized machines, 6 suction valves, 7 backhaul rollers, 8 synchronous cams, 9 rise rollers, 10 middle pressure valves, 11 spinning cylinders, 12 spinning rotors, 13 hyoplastrons, 14 suction ports,

detonation chambers

15,16 oil nozzles, 17 spark plugs, 18 output shafts, 19 starter motors, 20 intermediate gears, 21 timing gear, 22 shaftgears.

Embodiment spinning cylinder 11 as shown in Figure 1, 2 is provided with the middle pressure valve 10 that is made of reciprocal valve rod and slideway thereof to the air flue of detonation chamber 15, this valve valve rod is provided with rise roller 9 and backhaul roller 7, and the synchronous cam 8 that is connected in timing gear 21 can contact with two rollers respectively.The set suction valve 6 of rotor cylinder 1 makes it to be normally open by the spring mechanism of its housing, and promptly the spray row of the U-shaped air flue upper end-hole of valve body and detonation chamber mouthful communicates, when lower end mouth is positioned at cylinder towards the rotor rotation direction.The basic circle of rotor 2 is provided with the arcuation flange sections, along the matching gap that the rear end and the cylinder body of rotor rotation direction is provided with 0.01mm, promptly guarantees the effective rate of utilization of high pressure-temperature air-flow, has avoided the friction loss of rotor and cylinder body again.The basic circle of rotor and arcuation flange sections thereof all engage with the set roller in suction valve bottom, and suction valve is an opening state when being engaged in basic circle, are closed condition when being engaged in the arcuation flange sections, and flange sections is provided with and suction valve U-shaped air flue lower end mouth opposing end faces.

Single rotor internal combustion engine working procedure of the present invention is summarized as follows that the gearing of starter motor 19 is in output shaft 18.Be transmitted in spinning rotor 12 through shaftgear 22, intermediate gear 20 and timing gear 21, under hyoplastron 13 effects, finish air-breathing, the process of calming the anger.The synchronous cam 8 that is controlled by timing mechanism opens middle pressure valve 10 through backhaul roller 7, high pressure draught enters detonation chamber 15 and is vorticity, be subjected to oil nozzle 16 injected fuel of the suitable eddy airstream direction setting of timing mechanism control simultaneously, and fully mix with high pressure draught.Middle pressure valve 10 is closed immediately, spark plug 17 igniting, high-temperature high-pressure air flow enters the arcuation flange end face that rotor cylinder 1 acts on rotor 2 through spray row mouth, suction valve 6, it is rotated along the direction of arrow among Fig. 1, rotor after wide-angle more than 240 ° is rotated under its rotatory inertia effect, on the one hand the arcuation flange is closed suction valve, and the arcuation flange turns over relief opening and makes rotor cylinder enter exhaust phase on the other hand.Relief opening 3 makes waste gas enter pressurized machine 5 through power gas source pipe 4, increases the air inflow of air compressing cylinder by suction port 14.This machine goes round and begins again by said process and stably moves.

It is more apparent simple in structure that single rotor internal combustion engine of the present invention is organized combination more, the arcuation flange of each rotor is distributed in same output shaft by group number equal angles, and the control structure that synchronous cam and oil nozzle and spark plug are respectively organized in the same equal angles distribution of its Control Shaft of common timing mechanism both can.
