Abstract

The present invention relates to a tooth-embedded type cam rotor engine which is a pure rotor engine. The tooth-embedded type cam rotors of the engine are combined by elastic seal and labyrinth seal, and the problems of seal and blending combustion are solved. The present invention has the advantages of variable and adjustable compression ratio, no residual waste gas, smooth combustion, superior performance and wide and practical application, and a combustion chamber is not needed. The problem of power transfer is solved by a circular cylinder with a maximum stroke and a maximum torque moment of a constant force arm, and because of the combination of cylinders with unequal thickness, the engine can carry out spraying directly and pressurizing independently. The tooth-embedded type cam rotor engine combined by carburetors using various fuels or multiple direct spraying and pressurizing cylinders can be designed.

Structure of the present invention is: utilize cam mechanism principle composition as Fig. 1 and Fig. 2 by tooth-embed cam rotor 1 and circular cylinder body 2 and 3 three basic building blocks of driven cylinder cap.

Tooth-embed cam rotor 1 separates two groups to four periodic duty processes in rotatablely moving finishes, form and inhale pressure group and quick-fried row group, promptly inhale and press the chamber or inhale cylinder pressure V1 and quick-fried row chamber or quick-fried row's cylinder V2, form adjustable zero the firing chamber V0 of can be changed into of volume simultaneously, as Fig. 1 and Fig. 2 is a kind of dead axle, with one heart, and self balancing, along the pure rotor of circular path constant angular velocity rotation, and with composition tooth-embed cam rotor engines such as centrifugal seal bar 4 output shafts and interior air-cooling fan 5 composition boards 6 and end cap and accessories.

Creationaryly make whole rotor the forereach seal degree of Reciprocating engine and triangular rotor motor of periphery that slides with the method for usefulness, fundamentally solved sealing problem with elastic packing and labyrinth seal.

Tooth-embed cam rotor and circular cylinder body list double-cam rotor with thickening degree B1 〉=B2 combines, variable multiple compression ratio, form semicircular ring or the annulus cylinder of long stroke and the torsional moment of the maximum constant arm of force, combustion gas is expanded and is fully done work, output steadily, the slow-speed of revolution, height is turned round weak point, has solved the power-converting problem at all.

Adjustable variable volume is a not residual exhaust gases of zero firing chamber V0 on the function, and mixed gas or fresh air do not contact with waste gas, not fusion, and jubilant, the carbon deposit not that burns, pollution has solved the combustion regime problem less, at all:

The present invention is applicable to that carburetor engine also is applicable to the injection supercharged engine.

Its working procedure is: mixed gas or fresh air enter from intakeport inhales cylinder pressure V1, reach the firing chamber V0 that is pressed into quick-fried row's cylinder behind certain compression ratio by composition board 6, by the plug ignition outburst or by oil injecting nozzle oil spout heat combustion self-destruction, the expansive force acting, the actuating cam rotor produces rotary torsion, is exported by output shaft 5, simultaneously waste gas is discharged by relief opening.

Parts of the present invention are: tooth-embed cam rotor 1, as Fig. 3, Fig. 4, Fig. 5, Fig. 6, from radially separately all having radial side's tooth, male and female to inlay movingly on two fans, relative two interior edge faces, all there are two circle labyrinth sealing circles, centre to have 6 springs and 1 retaining air ring, cam point that seal strip groove is arranged on two exterior edge faces, 4 times dresses of last dress centrifugal seal bar corrugated sheet spring, axis of rotation are the spline axis holes, cam is a thin-walled, with 6 spokes supports, centres are ventilation cavitys, air-cooled in the rotor, solved rotor cooling problem.

Centrifugal seal bar 4 has two sections, as Fig. 7, with three sections, as Fig. 8, utilize wavy spring and ramp effect to produce elastic packing to three directions, its width dimensions＞14.5 millimeter cover spark-plug hole fully, air tight, Rd is that cylinder radius end face circular arc is a bit of arc of cylinder body circumference, seal by spring force and cylinder body during starting, sealed by centrifugal force, its positive pressure changes with rotating speed, and the corrugated sheet spring is with heat-resisting spring steel manufacturing, Stamping Steel Ribbon is selected the self-lubricating bearing material manufacturing for use, has solved a lubricated difficult problem.

The cam profile design does not have bump profile rotor with the design of dynamic elasticity theory analysis, the strength of parts design is calculated with the internal-combustion engine heat load intensity, all work is finished with the electronics computer-aided design, profile falls journey angle φ 2 differentiations with lift angle φ 1 to be had: single cam symmetry profile rotor such as Fig. 9, single asymmetric profile rotor of cam such as Figure 10 A-10E, double-cam symmetry profile rotor such as Figure 11, the asymmetric profile rotor of double-cam such as Figure 12 A-12B.

The thickness V1 of cam follower: the relation of V0, can design multiple compression ratio, use gas and oil, the tooth-embed cam rotor engine of diesel oil pluralities of fuel.

Material design requires identical to cam follower 1 and cylinder body 2 and composition board 6 and end cap etc., general available high-quality QT or HT, precision casting, thermal spraying M0, SiC, Si3N4 are selected in surface hardening, ZrO2, AL2O3, laser reinforcing, optionally decide with condition, more than the HRC60, heat-resisting more than 1000 ℃, little, minicomputer designs available SiC, Si3N4, and ZrO2 metal whisker composite integral roasting forms, change the design idea " become heat radiation into adiabatic ", can design the ceramic thermal insulation tooth-embed cam rotor engine.

Circular cylinder body 2 is as Figure 13, internal diameter is positive circular, in the guide-track groove of cylinder cap limiting stopper is arranged, cylinder body is connected to integral body, prevents distortion and spacing to driven cylinder cap, kill two birds with one stone, combining with cylinder body thickness B 1 〉=B2 and single double-cam rotor obtains semicircular ring or the annulus cylinder of long stroke and the torsional moment of the maximum constant arm of force.

Firing chamber V0 is provided with two spark plugs.Favourable burning, oil injecting nozzle can be installed again can directly spray burning from supercharging, and the cylinder body periphery advances, and relief opening is that straight tube is often opened, and resistance is little, flux is big, can design from supercharging directly to spray tooth-embed cam rotor engine.

The cylinder body Cooling Design has: the radial radiating fin cylinder body of air-cooled axial flow such as Figure 13, and air-cooled axial flow parallel fin cylinder body such as Figure 14, air-cooled circulation parallel ring-type radiating fin cylinder body such as Figure 15, the water-cooled design has: the dual-purpose cylinder body of water-cooled axial flow circulation such as Figure 16.
