Abstract

The internal combustion piston engine and oscillator lath transfers translation kind of motion of piston (1) within cylinder (3), into the rotation motion of the camshaft (6), where the translation movement of the piston, causes, first, oscillator motion of the oscillator lath (4), which afterwards is transformed into complex motion of the big piston rod (5), which finally is transformed into rotary motion of the camshaft (6). The piston rod (2), during its work is declined maximum (4) and minimum (3) degrees in relation to the axial axes of the piston. The applied principal is validated for multi-cylinder and multi-valve engine performances.The movable parts of the engine as they are the oscillator lath (4), support axes (11), common shaft (15) and part of the big piston rod (5) are cooling by oil (12), put in the oil reservoir (13) at the bottom of the engine bloc (14). The oscillator lath (4) can be performed with more than 4 legs, that is 6, 8, 10, 12, and 24 legs.

Description

INTERNAL COMBUSTION PISTON ENGINE AND OSCILLATOR LATH

Technique field related to the invention

The invention " Internal combustion piston engine and oscillator lath" is relating to the technique field of mechanical engineering, narrower field of machine or engine, that is to the internal combustion piston engine and to the field of particular lubrication of the 5 internal combustion piston engine. In accordance with the International Patent Classification the invention can be classified in the class F 02 B and F 01 M. Technique problem solved by the invention

The invention " Internal combustion piston engine and oscillator lath" resolves the problem of overcoming the friction resistance which are appearing to the standard types of 0 Otto or Diesel four-stroke or two-stroke engines because of the presence of the crankshaft and piston rod of the piston mechanism, which sometimes is declined under the angle of 40 degrees from the piston axes. The problem of engine lubrication is resolved, too. Description of the state of the art

The state of the art in the field of internal combustion engines, despite the existence 5 of many modern performed variants (multi-cylindrical, multi- valve, rotary Wankel engine or turbo charged Diesel engine) and permanent improvements, finely is relayed on the basic variants of Otto, Diesel or Wankel engines in theirs two or four stroke performance. The mechanic part of the both variants is relayed on the existence of the cylinder within that piston is moving. On the one end of the piston there is a piston rod connected with >0 crankshaft of the camshaft of some vehicle or other kind of machine. At the one end of the cylinder there are valves which are regulator of fuel inlet and the burned gases exhaustion. At the same end of the cylinder, opposite of the piston head there are spark plugs or valves for high-pressure air inlet,

During the process of fuel burning, because of the released energy the piston begins !5 moving and through the piston rod and crankshaft, the camshaft begins to rotate, too. There is transformation of translator motion of the piston into rotary motion of the crankshaft and camshaft. During the working process of the internal combustion engine there are friction resistance because of the piston motion throughout the cylinder. That is the reason why an additional elements so called compression or piston rings, are mounted. These rings are SO easy changeable after some time using period and in the same time their manufacturing costs are low comparing to the cylinder production costs. Decreasing friction in the internal combustion engine is performing by lubrication of all movable parts with oil moved by oil pump that works under pressure. The performance of the piston rod of the piston mechanism is done in such manner that initiate force which radial component implicate big friction force between piston (that is piston rings) and cylinder internal surface. In some time period, the piston rod could be declined under 40 degrees relates to the piston axial axes. From these reasons were developed internal combustion engines with high number of cylinders and valves, which balance the work of engine, but essentially the problem of piston rod, friction and lubrication is not completely solved till now. Technique problem solution The technique problem resolved by this invention contains design performance with four cylinder, oscillator lath, big piston rod, pistons, camshaft, eccentrics wheel, put into engine bloc with oil reservoir where it is partially flooded the oscillator lath.

The invention can be described easier if we look at the figures that are constituent part of the application. There are enclose two figures in which there are presented as follows:

- Fig.1 : Profile view of the engine, and

- Fig.2: Vertical view of the engine.

The working process commences by suck tact of the fuel and air mixture, where the piston 1 moves from the upper mortal point 10 toward lower mortal point 9. In the beginning of the process the oscillator lath 4 is found on its highest position and it is not flooded in lubrication oil 12, put in the oil reservoir 13, at the bottom of the engine bloc 14. In the end of the process od sucking, the piston rod 2 and the one end of the oscillator lath and the common axes 15 are flooded in the oil 12, while the piston 1 is found at the lower mortal point 9, ready for the next tact. The second tact characterizes the process of compression ("squeeze") onto the fuel and air mixture. It begins with motion of the piston 1 from the point 9 toward the point 10. At some distance from the point 10, the spark plug initiates sparking and easy burning of the mixture, where, because of the expansion of the fuel, which from liquid transfers into gas state, implicates come back of the piston 1 toward the point 9. The expansion of the gases represents the power or working stroke of the piston and working tact of the engine. Trough the piston rod 2, the power is transferred to the oscillator lath 4, which is connected with the big piston rod 5, which through the eccentrics wheel 7 transfers the oscillator motion into rotary motion of the camshaft 6, where the flywheel 8 is put. The oscillator late is relayed on the support axes 11. It oscillates in direction up down, whereas it initiates motion of the piston rod for 3 to 4 degrees in relation to the axial axes of the piston 1 and the cylinder 3. The solution facilitates significant decreasing of the radial force with which the piston 1 actuates toward the internal side of the cylinder 3, provided that the friction between the piston (usually piston rings) and the inner side of the cylinder. This provides increasing of the engine coefficient of useful acting. Except the presented solution with 4 cylinders, there are possible solutions with more then four cylinders. On the camshaft there is drive pulley 18, which across the pulley 16 transfers moments on the drive pulley 17 because of starting the other devices and instruments needed for engine whole functioning.
