Abstract

The utility model relates to a structure of a late-model rotary piston internal combustion engine. Mixed combustion gas is pressurized before the mixed combustion gas enters an air cylinder. After the mixed combustion gas enters the air cylinder, the mixed combustion gas is not compressed any longer. The utility model mainly comprises an air cylinder body (3) whose inner wall is cylindrical, a rotor (2) provided with a rotary piston surface (4), an output shaft (1) combined with the rotor, a swing blade (5), a vent hole (6), a spark plug (9) which is led through a cover of the air cylinder (7), an air inlet hole (8) and a valve. A combustion chamber is composed of the swing blade, a rotary piston rotor, a cupped part of the inner wall of the air cylinder body, and lateral plates at both ends. The utility model has two executive plans. Because a crankshaft connecting rod mechanism is cancelled, the utility model has the advantages of simplified structure, light weight, easy start, no knock, and stable running. The ratio of the mixed combustion gas can be controlled better before the mixed combustion gas is pressurized. The utility model is good for sufficient combustion of the mixed combustion gas, and lightens pollution for environment.

Description

Swing blade type rotary piston IC engine

The utility model proposes a kind of novel rotary piston RC engine structure.Current widely used Structure of Internal-Combustion Engine is just definite substantially before 100 years greatly.Propose the technological scheme of many rotary piston RC engines in recent years, but up to the present, also do not had a kind of obtaining to use more widely.The utility model with the remarkable difference of the various rotary piston RC engine technological schemes that proposed at present is: the compression stroke of cancellation combination gas in cylinder changes into before inlet casing supercharging carried out in combustion gas; Adopt a swinging impeller structure to aid in and form the firing chamber in the cylinder.This technological scheme has been simplified the structure of rotary piston RC engine, has reduced manufacture difficulty, thereby can reduce manufacture cost, makes rotary piston RC engine enter the practical stage.

The air cylinder structure of this internal-combustion engine shown in figure one, it comprise inwall be the garden cylindricality cylinder block 3., have rotary-piston face rotor 4. 2., the pto that is combined into one with rotor 1., the pendulum leaf 5., and be attached on the cylinder block cylinder head 7..On the cylinder block inwall, have exhaust port 6..By cylinder head introduce spark plug 9. with inlet hole 8. and valve.Both sides in cylinder block seal with the cylinder side plate.

Shown in figure one, form one section depression in cylinder head corresponding cylinder body inner wall surface, this section is recessed in the end near exhaust port, is communicated with a hole, garden with seam, in order to place the pendulum leaf.The firing chamber of this kind internal-combustion engine, by the pendulum leaf 5., the rotary-piston face 4., the sunk part of cylinder block inwall adds the side plate at two ends again and forms.8. combination gas after the supercharging enters the firing chamber through inlet hole, and inlet hole is closed then, and spark plug sparking causes mixture combustion, and the pressure of generation promotes the rotary-piston rotator rotation, directly sends power by output shaft.Can settle one on the output shaft to several rotors, can both link together a plurality of rotors, each firing chamber is isolated mutually, help to reduce the volume of internal-combustion engine by dividing plate.Can respectively open an annular groove at the dividing plate of many rotors and the sliding contact part of cylinder block inwall, insert an elasticity garden ring plate (being similar to piston ring).This both can further strengthen the mutual isolation effect of each firing chamber, can use the oil circuit of these two annular grooves as lubricant oil again.

When 2. rotor rotates, the pendulum leaf will be pushed to cylinder inner wall by epitrochanterian convex portion, and last latent fully sinking among the sunk part of cylinder inner wall.One end of pendulum leaf is made the garden cylindricality, is called butt, puts into the hole, garden with seam of cylinder block from the side.The other end of pendulum leaf is called the top, is made the outer arc surface of its contact rotor by the pressure of burning indoor gas.Therefore along with the rotation of rotor, the pendulum leaf will be swung in small angle.For reducing to put the sliding friction on leaf top and rotor outer arc surface, can implant roller on the top of pendulum leaf, make it to become rolling friction and strengthen lubricated.Lubricant oil can be pressed into the butt of pendulum leaf outside cylinder block, deliver to pendulum leaf top through overswing leaf itself as oil circuit again.

Spark plug and suction valve by the cylinder head introducing, in actual device, might be higher or lower than the cambered surface of cylinder block inwall, therefore require the pendulum leaf that corresponding depression or convex portion are also arranged, make the pendulum leaf latent fully when sinking into the cylinder block inwall, can not collide with spark plug and suction valve, reduce the residual space of firing chamber, also increased the intensity of pendulum leaf itself simultaneously.

3. second kind of embodiment become cylinder block into endocyclic position by outer ring position shown in figure two, 2. rotor then becomes outer ring position by endocyclic position.4. internal rotor radially forms rotary-piston to the part of axis direction projection.Can settle three little (teeth) wheel by the cylinder side plate or in rotor exterior, fix the position of rotor and stablize it and rotatablely move.Cylinder head can be cancelled, directly on cylinder block, settle spark plug 9. with inlet hole 8..The pendulum leaf 5. be subjected to force direction just in time opposite with first kind of scheme, for concave surface stressed, therefore the pendulum leaf intensity of second kind of scheme should design than first kind of scheme for high.Power is exported by the rotor outer.1. the position of motive force output shaft changes puts camshaft, in order to the switching of control air intake valve.Exhaust port 6., many rotor structures and working procedure are all with aforesaid first kind of scheme.

The other parts of this kind internal-combustion engine, as the combination gas supercharging, air intake valve control, electrical spark control, lubricated and heat radiation can adopt the ordinary skill in the field of internal combustion engine to realize.Owing to cancelled crankshaft ﹠ connecting, make designs simplification, weight saving starts easily, and no pinking moves very steady.The ratio of combination gas can be controlled before supercharging preferably, helps combination gas and fully burns, and alleviates the pollution to atmosphere environment.
