[0001] The present Patent of Invention consists in a new system to produce a greater power
and to eleminate the oscillation (tinkling) of the pistons in an internal combustion
engine, thus offering substantial advantages in any mechanism of connecting rod-crank.
[0002] This system eleminates a series of inconveniences which are frecuently produced specially
in Diesel-motors, but also in those of petrol.
[0003] The internal combustion or the Diesel motor work in the same way with regard to the
running of the connecting rod as impulse transmitters which is produced in the piston
by reason of the abrupt combustion of the mixture contained in the chamber.
[0004] Now, this is more frequently the case in engines of Diesel cycle which produce a
tinkling noise (oscillation) of the pistons, than in the petrol engines where it is
produced with less intensity.
[0005] As in all the know cases the piston, the connecting rod and the crankshaft are three
elements that though they are subject to modifications of thickness, length, and in
the case of the piston of the shope of its head, they fulfill the same function which
cannot avoid that in these motors are produced the same disadvantages which existed
always, though the used materials be of very best quality.
[0006] The device in question produces an advantage on a series of inconveniences which
arise frequently in all Diesel motors, and very often in those of petrol.
[0007] They are principally the vibration produced by the compensated inertias lengthwise
the crankshaft, and the movementof then connecting rods which the piston supports
alternately on the opposite sides of the cylinder, being the effect the tinkling or
oscilation of the piston.
[0008] In order to make the following explanation clearer and more comprehensible, is joined
to this specification two sheets of drawings forming part of same, which in seven
figures represents, as way of example, all which constitutes the essence of the present
Patent of Invention and on which is shown the principle of its method of operation.
[0009] The present invention constitutes a motor provided with connecting rods which have
a specially characterized shape, because they increase the received force owing to
the inertial effects that add up and favour the motive effects.
[0010] Said connecting rod cansists of a piece the shape of which causes a displacement
of its gravity centre subject to the axle of the bolt centres to the crankshaft respectively,
provided with a rigid structure, and provided as the other connecting rods with two
devices at its ends to be fixed to the piston on the one hand, and to the crankshaft
on the other.
[0011] The performance of this piece in a motor will be the following:
[0012] Once the piston begins its downward course by reason of the thrust that provides
the sudden exidation of the compressed misture of the chamber, it will produce a force
on the connecting rod which same transmits on the crankshaft.
[0013] Owing to the displacement of the gravity centre of the connecting rod (of an original
design and greater weight), it will produce some inertial effects resulting in an
oblicue thrust influencing directly on the crankshaft in a favourable sense, i.e.
towards the outside of the crankshaft rotation.
[0014] At the lower. part, which is the one joined to the crankshaft, will be produced a
force in a favorable sense to the crankshaft rotation owing to the mentioned inertial
effects which effect favourably the overcoming of the dead points, specially the upper
one.
[0015] Now, if one keeps in mind that the yield of an internal combustion engine of rapid
rotation rarely surpasses 30% of the power employed for its movement, one can clearly
deduce that there exists a certitude to increase by means of this method the motor
yield in a proportion to the energy consumption arisen from the explained positive
inertial effects, produced precisely by the displacement of the gravity centre of
the connecting rod.
[0016] Though the motor power is already considerably increased by virtue of the regularity
that produces the thrust effected by a crankshaft provided with a connecting rod in
very favourable conditions, the motor turning moment is still more increased by this
system. This makes possible that the minimum speed of the motor, which at another
moment and with a conventional motor would normally not go down more than 800 rpm
in this one it is possible that the regular working at ticking over can be lowered
to less that 500 rpm, which no motor (of four cylinder9 of traditional structure regularly
supports, taking into account that from this speed is obtained a sufficient turning
moment, and a motor capacity to recuperate revolutions which according to the "present
setting out is considered as "amazing".
[0017] Fig. 2 shows a schema of the position the proposed connecting rod occupies and the
shape it can take, opposite to the one of fig. 1 which is the classic one.
[0018] On this fig. 2 can clearly be appreciated that though the piston thrust is produced
downwards, being this the direction of its course from its upper dead point, the resultant
of the inertial effects will be produced in an oblique way according the line drawn
with (1) (appreciatively) so that they will provide a quicker rotation of the crankshaft.
[0019] Figures 3, 4, 5 and 6 show a development of the piston course, first downward and
the upward.
[0020] Fig. 4 reproduces the moment at which the downward course of the piston has reached
the middle, and on which can be seen that the distance during the descent of the piston
from the centre of the crankshaft rotation to the gravity centre of the connecting
rod, which is the inertial power point pressing downwards, constitutes a greater turning
moment owing to the greater distance of the gravity centre thus favouring the motive
effects.
[0021] FIg. 5 represents an aspect at which the piston begins its upward course, marked
with 7.
[0022] Fig. 6 represents the same aspect of the ensemble when the piston is at the middle
of its upward course, and on which can be seen marked with (8) the gravity centre
of the'. connenting rod, which is situated at a much shorter distance from the rotation
centre of the crankshaft, as represented with (9), and with regard to the case of
fig. 4.
[0023] On the figure 7 can be appreciated its shape based on three fundamental axles, viz.:
- Angle marked with A. It determines the inclination of the foot of the connecting
rod, which will be of seven degrees, more or less a tolerance of four degrees.
-Angle marked with B. It determines the inclination of the body o.f the connecting
rod and this will be of sixteen degrees, more or less a tolerance of sic degrees.
- Angle marked with C. It determines the inclination of the head of the connecting
rod and this will be of thirty-three degrees, more or less a tolerance of seven degrees.
[0024] All this angles are taken on the vertical axle of the connecting rod.
[0025] Said connecting rod will work in the motor as follows:
[0026] Once the piston begins its downwards course by reason of the thrust the expansion
of the compressed mixture in the chamber is providing, will be produced a power on
the connecting rod, which same transmits on the crankshaft with different thrust.
[0027] Therefore is modified the disposition of the connecting rod with regard to the crankshaft
in relation to the customar ones.
[0028] By this disposition is produced the following advantage:
[0029] THe tinkling (oscillation) cannot be produced because the resulting thrust of the
connecting rod on the crankshaft is produced in an oblique way and is not burdened
against the body of the crankshaft directly, but produces the force on an eccentric
and external point of the crankshaft, which allows a grater positive inertial resultant
than if the force is initiated on the upper port, so that the variations of the motor
rotation, as well for its increase of speed as for its retention, do not produce any
tinkling/oscillation in the piston.
[0030] From the above can be followed that by applying the present proceeding to an internal
combustion engine, its yield will be increased.
[0031] There has also to be mentioned here, that once this proceeding is used, it has to
be equipped with a suitable distribution diagram which permits the feeding times to
be the most favourable.
[0032] In order to obtain the mentioned yield, one has to count necessarily with a specially
designed connecting rod so that the mentioned effects are produced.
[0033] It has to be pointed out that with this proceeding is increase the yield of the motors
having as object the rotation on the crankshaft, and any mechanism or device of connecting
rod-crank. Thus, this method is very efficient for example in internal combustion
engines, pumps or compressors.
[0034] From the above explanation can be followed that by applying connecting rods as the
specified ones to an internal combustion engine, the yield fo same will be increased
in proportion to the displacement of its gravity centre and to the weight of the connecting
rod.
[0035] Thus, one has to count necessarely with a connecting rod having the abovesaid characteristics.
Once the proposed angular deviations are specified, this, which is variable according
to the characteristics of each motor, and according to the Searched yield, will be
applied in each case.
[0036] It is convenient to point out that by means of this device is encreased the yield
of the motors, the object of which is the rotation on the crankshaft.
[0037] By means of the present proceeding can be obtained a combustion engine of rapid revolution,
an advantage of its remarkably higher yield.
[0038] It has be pointed out that in the present Patent of Invention the drawings as well
as the explanation given in the contents of this specification, are made by way of
example only, being comprised in it all the modifications which have not as result
to vary the explained essential contents.
[0039] Once explained the working characteristics of the present proceeding, there is specified
the protection of this Patent of Invention in the following
1.- Proceeding to produce positive inertial effects and a differentiated motor behaviour
in internal combustion engines characterized because the connecting rods have an asymetric
shape which displaces the gravity centre with regard to the axle piston-pad of the
crankshaft.
2a.- Proceeding characterized according to claim 1, because there are produced additional
inertial effects owing to the greater weight of the. connecting rod, this weight being
influenced through its gravity centre.
3.- Proceeding characterized according to the two previous claims, because the additional
inertial effects of the connecting rod perform a greater lateral pressure of the piston
on the wall of the corresponding cylinder, which avoids that there arises the oscillation-tinkling
of the piston flap.
4.- Connecting rod characterized because it is constituted by a piece provided at
its ends with devices to be fastened at the piston and to the crankshaft which considering
in vertical the upper fixing device to the piston, and in line with the fastening
to the crankshaft, is introduced an inclination of:
- 7Q ( - 4Q) in the fixing of the angle of the connecting rod foot.
- The body of the connecting rod is inclined 160 ( ±6Q).
- The head of the connecting rod is inclined 330 ( ± 7Q), in such a way that when
the upper fastening of the connecting rod receives the pressure of the piston produced
by the explosion or combustion of the motor, there occurs a thrust which exerts a
more favourable turning moment, owing to the resultant of the thrust force also opened
in rotation sense and of greater value.
5.- Connecting rod characterized according to the fourth claim, because at the upper
dead point is produced by reason of the favourable inclination of the connecting rod
an exterior resultant from the fastening point of the connecting rod to the crankshaft
be vertically aligned.
