[0001] It is an Internal Combustion, piston-bearing, retrogressive, four-stroke, four-cylinder,
over-quadrangular Engine, using gasoline as principal combustible. It can be lubricated
and is water cooled.
[0002] The advantages in comparison to the other engines are the following:
[0003] It presents smaller weight, smaller width, smaller volume, a smaller number of moving
parts, smaller retrogressing masses, activation of the two pistons by a single moving
part. The two pistons share the same cylindrical space, rectilinear shaft, compact,
low power rejection, decrease of surfaces under friction. Easier drawing and manufacture,
easier maintenance, lower purchasing cost than a flat engine.
[0004] A practical application is given by referring to the attached drawings.
[0005] In figure 1, we see a side view of the engine's disposition.
[0006] In figure 2, we see a frontal view of the engine.
[0007] In figure 3, we see a plan view of the engine.
[0008] Referring to the drawings, the engine includes a rectilinear shaft - 1 - with its
counterweights - 2 - 3 - and four pistons - 4 -. Initially, the two pistons - 4 -
are placed at one part of the engine's trunk, the shaft penetrates through the body
of the pistons and counterweights, which clamp on it and finally, the of the two parts
of the engine's trunk, takes place.
[0009] The rectilinear shaft is set on common bearings, and possesses three bearings and
two slipping counterweights - 2 - 3 -. The counterweights clamp over the shaft with
the screw - 5 -, and they are also placed eccentrically and in a disposition of 180
degrees, from each other. The screw of the counterweight can receive a ring shaped
safety pin - 7 -. Every counterweight is subjected on its surface, peripherally, to
a grinding (smoothening), in order to slide over the lower part of the piston. The
four pistons - 4 - are two unified, and they are connected together with four connecting
bars. The two unified pistons are a moving part and share the same cylindrical space,
and are also activated by a counterweight. The two pistons are cast simultaneously
on the four connecting bars. The bars are made from hard metal, in order to withstand
the fatigue of the counterweight and to support the pistons. The bars adjoin only
over the counterweight in order for the pistons always to be in a linear course. Now,
the pistons possess, internally, a rib - 6 - with a hard metal casing at the lower
part, where the counterweight slides. The piston also possesses, internally, two smaller
ribs - 6a - in order not to be deformed during the operation. Externally, the pistons
possess common springs - 8 -. The pistons have lateral openings for the shaft to penetrate
through and to rotate and sections from above, for the rotation of the counterweights.
Finally, the engine produces work only with the cylinders in flat disposition.
[0010] This engine can be placed on any vehicle, it is piston-bearing, retrogressive, four-stroke,
four-cylinder, over-quadrangular, uses gasoline as principal combustible, accepts
lubrication and is water cooled. Finally, it produces work with the cylinders only
in level disposition.
1. It is an internal combustion engine, which is characterized by the fact, that it consists
of a rectilinear shaft - 1 - with its counterweights - 2 - 3 - and the four pistons
- 4 - . Initially, the two pistons - 4 - are placed at one part of the engine's trunk,
the shaft penetrates through the body of the pistons and counterweights, which clamp
on it and finally, the of the two parts of the engine's trunk, takes place. The rectilinear
shaft is set on common bearings, and possesses three bearings and two slipping counterweights
- 2 - 3 -. The counterweights clamp over the shaft with the screw - 5 -, and they
are also placed eccentrically and in a disposition of 180 degrees, from each other.
The screw of the counterweight can receive a ring shaped safety pin - 7 -. The pistons
possess, internally, a rib - 6 - an also two smaller ribs - 6a - in order not to be
deformed during the operation.
