Abstract
The present invention solves the problem of achieving optimum performance of a piston-type internal combustion engine. Piston-type internal combustion engine crank mechanism is characterized in that the crankshaft is replaced by a slide system. The slide system consists of a slideway (4) and a slid element (5) and is connected to at least one piston (1) and the crank in the crankshaft (6). Piston-type internal combustion engine differential motion is characterized in that it has a bar (10) mating with a camshaft (8) and valves (13).
Description
Piston-type Internal Combustion Engine Crank Mechanism and
Differential Motion
The subject of the present invention is a piston-type internal combustion engine Crank mechanism and piston-type internal combustion engine differential motion, particularly in four-valve systems.
Known in the art. a crank mechanism created during the initial phase of piston, engine development. That mechanism consists of four essential parts: a cylinder, a piston, a connecting rod and a cranlcshaft. In the course of piston engine crankshaft rotation. Further, crank mechanism in crosshead engines is characterized in that the cap of the connecting rod is supported not on piston rod but in a crosshead that slides along a slideway. All the above mentioned mechanisms share a common principle of the operation, according to which the reciprocating movement of the piston is converted to the rotating movement of the crankshaft by the action of the connecting rod which performs both reciprocating and swinging movement.
It has turned out, unexpectedly, that replacing the connecting rod by a slide system made it possible to achieve optimum performance of the engine.
The distinguishing feature of the present invention is the replacement of the connecting rod by a slide system. The slide system consists of a slideway and a sliding element, whereas the slide system is connected to at least one piston and the crank of the shaft. According to the first embodiment of the present invention, the slideway has the form of a straight line.
According to the second embodiment of the present invention, the slideway has arc-shaped outline.
According to the third embodiment of the present invention, the sliding element is a part of the crank in the crankshaft.
Another distinctive feature of a piston-type internal combustion engine crank mechanism according to the present invention is that valve mechanism is
provided with a bar which mates with the crankshaft and the valves. According to an embodiment of the present invention, the bar includes a guiding part consisting of a mandrel and a seat.
The present invention increases crankshaft torque in the initial phase of shaft Rotation during the working stroke of the piston, which increases the acceleration of the engine's crankshaft rotation, thus increasing the acceleration of the motor vehicle. Another advantage of the present invention is increased power of the engine as well as reduced load of the engine cranlcshaft bearings. The subject of the present invention is illustrated in a drawing, where Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 6 depict the crank mechanism in an internal piston-type combustion engine, and Fig. 4 depicts a schematic layout of the engine's cylinders, whereas Fig. -5 and Fig. 6 depict the second embodiment of the piston-type internal combustion engine cranlc mechanism, while Fig. 7 depicts piston-type internal combustion engine differential motion, and Fig. 8 depicts the third embodiment of the present invention where the sliding element is a part of crank in the cranshaft.
The piston-type internal combustion engine crank mechanism according to the present invention has pistons 1 situated inside cylinders 2 which are com ected through brackets 3 to slideway 4. Slide 5 mates with slideway 4. 50. in the third embodiment of the present invention, slide 5 is also a part of a crank in the shaft 6. An action of force F created by combustion of fuel causes movement of pistons 1 and slideway 4 which causes movement of sliding element 5, which, in turn, causes shaft 6 to rotate in specified direction.
The piston-type internal combustion engine differential motion includes cap 7 which houses camshafts 8 provided with cams 9. Rotary camshafts 8 mate through cams 9 with bars 10 slide-mounted by mandrels H in seats 12. Rotary camshafts 8 press through cams 9 against bars 10 which open valves 13.. After camshaft 8 rotation is completed, valves H are closed with springs 14, thus moving bar 10 into starting position.
