Description

Inside rotor IC engine

The present invention relates to a kind of internal combustion type thermal engine (internal-combustion engine) with the electrical spark positive ignition, target tightening is at its operation element--on the piston.

In view of all drawbacks of traditional internal-combustion reciprocating-pisto, the present invention discloses the technological scheme that a kind of piston directly rotates acting, thereby gives up the crankshaft ﹠ connecting of the conversion power direction of relying.

Starting point of the present invention is at the method for operation of piston in cylinder.The compressed gas of traditional combustion engine is when burning, the active force of expanding gas is applied to just by on the descending piston area of top dead center, this moment is owing to crank arm and the also intimate straight line of the angle of cut of connecting rod, active force can be offseted in a large number by the mechanical obstacles of self, the moment of torsion of output is bordering on zero, have only when descent of piston to crank arm (active force is in the tangent direction of rotation garden face of cranking arm) when vertical with connecting rod, moment of torsion just reaches maximum value, yet this status pole instability, ratio shared in piston stroke is very little, moreover the space of piston displacement at this moment has been equivalent to the several times of combustion chamber volume, the expansive force of combustion gas weakens greatly, it is zero that the piston arrives lower dead center follows the same moment of torsion of situation at top dead center to fall sharply again, each work cycle moment of torsion all is in and thisly follows hard on and get back to zero cyclically-varying by zero to maximum value, and this is the basic reason that original technology can not increase substantially mechanical efficiency all the time.This programme then can be included in following vital technical factor in the distinctive mechanical type for solving this difficult problem:

One, combustion chamber volume only is 1 with the ratio of the acting chamber volume of piston: 1.5--1: 1.2, and energy is able to the most effective application.

Two, the working stroke of piston surpasses the transition stroke, and the auxiliary merit that inertial force is done is few.

Three, the moment of torsion of live axle output is not periodically-varied.

Four, valve-opening time is long, and combustion gas sucks sufficient.

Five, each work cycle can both drain waste gas, and pure combustion gas can fully be burnt.

Focus of the present invention is: form the firing chamber that intermittently occurs with the piston plate that can take down the exhibits.As previously mentioned, the tradition type intrinsic technological deficiency all to come from piston acting be axial displacement, so what finally obtain can only be the straight line motion of piston, having to remove to change power direction by crankshaft-link rod just can make live axle be rotated, it is extremely rough to do work, do not allow piston to come and go in the firing chamber in addition, each work cycle all can not drain the waste gas that remains in the inside, the present invention the combination of unique machinery then successfully solved the incompatible contradiction of firing chamber and piston, the piston acting is a lateral displacement, active force (explosive force of combustion gas) is applied to the tangent direction of rotor all the time, its stressing device is the piston plate that can agitate that joins together with rotor, the intermittent type firing chamber that is formed by taking down the exhibits of it and the acting chamber of piston constitute jointly the space of rotary-piston operation, so have the work general layout of breakthrough below having formed: each work cycle all is that the firing chamber is by the evolution process that is formed into disappearance.

The present invention is the energy with the gaseous fuel, and piston does not produce condensing routine to combustion gas, and the compression of combustion gas is unaided by compressor outside cylinder, and the size of pressure is according to the load regulated at will, and combustion gas must not compressed under idling and little load condition.

The running of laboratory model machine shows that main advantage of the present invention shows the following aspects:

One, owing to saved crankshaft-link rod, so both there be not reciprocal inertia force, also do not have hunt effect, running is steady, the efficient height.

Two, the inlet and outlet door is not set up control mechanism, and is simple in structure, and it is extremely reliable to work.

Three, all part profile standards, easy processing, cheap.

Four, volume is little, and is in light weight.

Five, be convenient to the multi-cylinder combination.

In sum, implement the objective of the invention is to: utilize a kind of brand-new working principle, thoroughly change the mechanical concept of traditional combustion engine, utilize the explosive force promotion piston of combustion gas directly to rotate acting most effectively.

Below with regard to the basic data of laboratory model machine introduce in detail in conjunction with the accompanying drawings geometrical construction of the present invention and the running mechanism.

Accompanying drawing (amount to a width of cloth) is for throwing off the position of each several part in cylinder end surface shape behind the front end housing and the cylinder.

Cylinder body (1) is a short garden tubular, and size is decided by desired volume, and two ends seal with forward and backward cylinder cap.What biasing was arranged in its inside is the rotor (2) of short garden tubular equally, the interior empty equal in length of its length and cylinder body (1).The ratio of the external diameter of the internal diameter of cylinder body (1) and rotor (2) is 4: 3, and the outer garden face of the interior garden face of cylinder body (1) and rotor (2) is tangent, and this is an essential characteristic of the present invention.

Rotor (2) is to the clockwise direction rotation, and its end has the end, and the center of bottom has incorporate with it live axle (8) to stretch out front end housing, and the other end is uncovered in order to insert inner core (4), because it has certain thickness, so have the function of flywheel again concurrently.There is exhaust port (10) on right side, point of contact at rotor (2) and cylinder body (1).

Key component of the present invention is piston plate (3).Its one side is bound up on the outer garden face of rotor (2) with rotating shaft.It is the cambered surface square that can agitate around axle.Its internal surface radian equates that with the internal surface radian of rotor (2) the outer surface radian equates with the internal surface radian of cylinder body (1).Because it is subjected to the acting in conjunction of these three power of impulse force of the rotary centrifugal force of the pressure of spring sheet (11) and rotor (2) and high-pressure gas all the time, the another side that is enough to guarantee it is close to casing wall all the time and is slided.Its receive can with rotor (2) one integrated mass, have no resistance ground by the point of contact, open up and then form firing chamber (9), intercept and clear away the waste gas that work cycle is remaining.When piston plate (3) when fully launching, power connection is ignited, and the internal surface that the explosive force of combustion gas acts on it with the form of its volumetric expansion promotes rotor (2) rotation makes live axle (8) output torque, and its function is equivalent to a blade of gas turbine.Can find out that thus the present invention had both utilized the explosive force of internal-combustion engine, can obtain the high efficiency of gas turbine again.Just in time fill the rectangular breach on the rotor (2) when piston plate (3) draws in, this breach is exactly valve (5).The coupking shaft of the point of contact of rotor (2) and cylinder body (1) and rotor (2) and piston plate (3) lays respectively at the diameter two ends of rotor (2).What must emphatically point out is: can be used as easily damaged parts to piston plate (3) and change.Because it and casing wall are Elastic Contact, contact segment can be made of carbonaceous material, thereby finishes to use in the cylinder of internal-combustion engine the history of lubricant oil.

Inner core (4) also is a short garden tubular, its external diameter equates with the internal diameter of rotor (2), and until the bottom, the other end is fixed on the back cylinder cover its end by the uncovered insertion of rotor (2), it is that the interior axle of rotor (2) is again the passage of combustion gas simultaneously, or the switch of valve (5).With the staggered position of valve (5) intensive inlet hole (6) is arranged over against the firing chamber at it, there is spark plug screw (7) at the position of closing valve (5) at it.

The end face of firing chamber (9) is crooked wedge shape, and suction stroke can reach 170 ° of-175 ° of garden round angles, the acting chamber (12) of piston plate (3) just in time with its symmetry.This wedge-section combustion chamber compares with traditional cylindricality firing chamber, garden, and its superiority is: one, can improve energy utilization ratio: the reaction force that two, can eliminate the combustion gas outburst; Three, can avoid pinking.

So far can think that the present invention has three big characteristics of current internal-combustion engine technology development: one, fuel gasization; Two, simplify the structure; Three, component functional diversities.

The position of the various branches that provide among the figure is in piston plate (3) and fully launches firing chamber (9) and formed combustion gas already and suck and to stop intake valve (5) exhaust port (10) and all closed situation on the occasion of igniting outburst acting.Rotor (2) whenever rotates a circle and finishes a work cycle, and piston plate (3) is taken down the exhibits once.The working stroke of piston plate (3) is 200 °--220 ° of garden round angles.Acting, exhaust are carried out simultaneously.
