Description

The present invention relates to mechanical engineering, in particular to the production of internal combustion engines (ICE).

Known piston engine containing a housing formed by two parallel walls, channels for supplying and discharging the working fluid, an output shaft, a piston made in the form of an articulated four-link with sealing elements, one top of which is pivotally connected to the axis, and the other to the output shaft, a variable chamber volume formed by parallel walls and the inner surfaces of the four-link placed with the ability to move the links relative to the parallel walls, a cover placed between parallel with with the formation of a chamber of variable volume between the outer surfaces of the four-link piston and the edge, the axis made in the form of a rotary eccentric, and the output shaft with an eccentricity in the form of a disk, and the camera of variable volume communicated using the bypass channels (see patent RU No. 2009348 C1. Piston engine. F02V 75/32. Publish. 15.03.94. Bull. No. 5). The disadvantage of the engine is a push-pull cycle, a large size and the presence of bypass channels communicating a variable volume chamber, which complicates its design and increases their resistance.

A four-stroke piston ICE is known, comprising a cylindrical crankcase, a crankshaft with round cheeks, at least one pair of connecting rods connected directly to the connecting rod neck of the crankshaft, or, when one of each pair of connecting rods, called trailed, is articulated to another main connecting rod connected with a connecting rod neck, head with intake and exhaust valves, spark plug or nozzle for a diesel engine, the number of heads with valves, spark plug or nozzles for a diesel engine is equal to the number of pairs of connecting rods, head size inside the crankcase symmetrically relative to its inner generatrix between the crankshaft shaft cheeks, to each of each pair of connecting rods one beam is articulated, having kinematic connection with the corresponding head so that the valves and the spark plug or nozzle at the diesel are between the joints, the width of each connecting rod, the rocker arm and the length of the head is equal to the distance between the cheeks of the crankshaft shaft, and the total length of the connecting rods in each pair is equal to or less than the total length of the rocker arms attached to them and the head width (see RF patent for the invention No. 2300002 C1, F02B 75/36, publ. 05/27/2007. Bull. No. 15). The disadvantage of the engine is the complicated design of the gas distribution mechanism (timing) and the difficult conditions of its operation, which makes it difficult to improve the specific performance of the engine. However, the design of the timing and its working conditions can be improved, which will improve the specific performance of the engine.

The technical task of simplifying the design of the timing, improving its working conditions and improving the specific performance of the engine is achieved by placing the inlet channel with the inlet valve and the outlet channel with the exhaust valve in the root journal of the crankshaft and adjacent cheek.

Thus, according to the invention, an internal combustion engine comprising a cylindrical crankcase, a crankshaft with round cheeks, at least one pair of connecting rods connected directly to the connecting rod neck of the crankshaft or, when one of each pair of connecting rods, called trailed, is pivotally connected to the other the main connecting rod connected to the connecting rod neck, a head with a spark plug or a nozzle on a diesel engine, an inlet channel with an inlet valve and an exhaust channel with an exhaust valve, the number of heads and candles being lit the diesel engine nozzle or nozzle is equal to the number of connecting rod pairs, the heads are placed symmetrically inside the crankcase relative to its inner generatrix between the crankshaft cheeks, each beam connecting rod is articulated to each of the connecting rods kinematically connected to the corresponding head so that the spark plug or nozzle diesel engines are located between the hinges, the width of each connecting rod, rocker arm and head length are equal to the distance between the cheeks of the crankshaft, characterized in that the inlet channel with inlet valve and exhaust al with an outlet valve arranged in the neck of the root of the crankshaft and the adjacent cheek of the shaft so that the position of the crankpin vertically downward relative to the shaft rotational axis of the crankshaft inlet channel with an inlet valve located on the left and exhaust channel with an exhaust valve is located on the right.

Where: 1 - the crankcase, 2 - the top head, 3 - the crankshaft cheek, 4 - the end cap, 5 - the intake valve, 6 - the spark plug (diesel nozzle), 7 - the exhaust valve, 8 - the upper cavity for the flow of the working cycle , 9 - lower head, 10 - lower cavity for the running cycle, 11 - inlet channel, 12 - exhaust channel, O - axis of rotation of the crankshaft, K - hinge of the connecting rod neck of the crankshaft (crank), AB, DE, PR, LM - rocker arms, DC, RK - main connecting rods, BS and MN - trailed connecting rods, A, B, C, D, E, K, L, M, N, P, P - hinges.

An engine with one working cavity for a four-stroke duty cycle contains a fixed crankcase 1, inside of which a head 2 with a spark plug 6 is placed on top of a gasoline engine (diesel nozzle) and a crankshaft with two round cheeks 3 and a connecting rod neck with a hinge K is coaxially mounted having an axis of rotation O (FIG. 1). The crankcase 1 is closed on both sides by two end caps 4, which serve as a support for the crankshaft. Between the cheeks 3 of the shaft mounted rods BS and DK, pivotally connected to the connecting rod neck with a hinge K (hinges C and K are combined). The beam AB is connected to the hinge B of the BS connecting rod, the DE beam is connected to the joint D of the connecting rod DK. The rocker arm AB is hinged A, and the rocker arm DE hinge E is attached to the head 2 so that the spark plug 6 (nozzle at the diesel engine) is located between the hinges. The width of the connecting rods BS, DK, rocker arm AB, DE and the length of the head 2 is equal to the distance between the cheeks 3 of the crankshaft shaft. The inner surfaces of the connecting rods BS, DK, rocker arm AB, DE, head 2 and cheeks 3 of the crankshaft form a closed cavity 8 for a four-stroke duty cycle, the volume of which cyclically changes during one revolution of the crankshaft. The main neck of the crankshaft shaft and the adjacent cheek 3 comprise an inlet channel 11 with an inlet valve 5 and an outlet channel 12 with an outlet valve 7.

In the initial position, the crank with the hinge K of the crankshaft relative to the axis O is turned vertically downward (FIG. 1). The connecting rods BS, DK, rocker arms AB, DE are located vertically, brought together and form a closed cavity 8 of the minimum volume. With respect to the axis of rotation O, the inlet channel 11 with the inlet valve 5 is located on the left, and the outlet channel 12 with the outlet valve 7 is located on the right. The valves 5 and 7 are open and combined with the cavity 8. The cavity 8 is in communication with the atmosphere through the inlet 11 with the open inlet valve 5 and through the exhaust channel 12 with the open exhaust valve 7. Into the volume of the cavity 8 through the inlet channel 11 and the open inlet valve 5 fresh combustible mixture (air charge at the diesel engine), and the exhaust gases are displaced from it through the open exhaust valve 7 and exhaust channel 12 into the atmosphere.

When the crankshaft rotates from its original position clockwise by the first quarter of a turn, the rocker arm AB with respect to the hinge A rotates at a low angular velocity (Fig. 2). The cheek 3 with the inlet channel 11 and the inlet valve 5, with the outlet channel 12 and the exhaust valve 7 relative to the axis O of rotation of the crankshaft rotate clockwise. Relative to the axis of rotation O, the inlet channel 11 with the inlet valve 5 are displaced to the upper position, and the outlet channel 12 with the outlet valve 7 are displaced to the lower position. At a certain angle of rotation of the shaft, the cranked rotation of the BS connecting rod relative to the hinge B clockwise shifts the cavity 8 outside the exhaust valve 7. The exhaust valve 7 is closed, the cavity 8 is isolated from the atmosphere and the “release” cycle of the previous four-stroke duty cycle is completed in a timely manner.

Rocker DE relative to hinge E, connecting rod BS relative to hinge B rotate clockwise, the volume of the cavity 8 increases, a vacuum is created in it. The combustible mixture (air charge at the diesel engine) through the inlet channel 11 and the open inlet valve 5 enters the cavity 8, which ensures a timely start of the “inlet” cycle of the new duty cycle in it. The rotation of the intake valve 5 in a clockwise direction combines it with the cavity 8 and ensures that the “intake” stroke flows therein during the first quarter of a revolution. When the crankshaft is rotated a quarter of a turn, the volume of the cavity 8 reaches its maximum, it is filled with a combustible mixture (air from the diesel engine).

When the crankshaft is rotated by a second quarter of a turn, the rocker arm DE relative to the hinge D rotates at a low angular velocity (Fig. 3). With respect to the axis of rotation O, the inlet channel 11 with the inlet valve 5 takes a place on the right, and the outlet channel 12 with an outlet valve 7 takes a place on the left. Moving the BS connecting rod relative to the axis of rotation O to the head 2 shifts the cavity 8 beyond the limits of the intake valve 5. The intake valve 5 is closed, the cavity 8 is isolated from the atmosphere and the “intake” cycle of this operating cycle is completed in a timely manner. The volume of the cavity 8 is reduced, which ensures the timely start of the “compression” of the working cycle in it. At a certain angle before the completion of the second quarter of the revolution, the spark plug 6 in the cavity 8 ignites the combustible mixture (fuel is injected into the diesel nozzle). The combustion of fuel in the cavity 8 leads to an increase in the pressure of the combustion products on the inner surfaces of the connecting rods BS and DK, and through them to the connecting rod journal with the hinge K of the crankshaft. When the crankshaft rotates from its initial position two quarters of a revolution, the “compression” cycle is stopped.

When the crankshaft is rotated by a certain angle of the third quarter of a revolution, the resultant force from the gas pressure acting on the connecting rod neck with the hinge K relative to the rotation axis O forms a shoulder, which causes a torque to appear in it. Torque crankshaft rotate a third quarter of a revolution (figure 4). Rocker AB with respect to hinge A rotates with low angular velocity. The rocker arm DE relative to the hinge E, and the connecting rod BS relative to the hinge B rotates counterclockwise, which increases the volume of the cavity 8 and ensures the timely start of the “expansion” beat in it. With respect to the axis of rotation O, the inlet channel 11 with the inlet valve 5 are displaced downward, the outlet channel 12 with the outlet valve 7 are displaced upward. The connecting rod DK is shifted to the axis of rotation O and at a certain angle of rotation, the cavity 8 is combined with the exhaust valve 7. The exhaust valve 7 is opened, the cavity 8 is communicated with the atmosphere, which ensures the timely completion of the “expansion” beat and the beginning of the “discharge” beat (Fig. .four). The exhaust gases from the cavity 8 through the open exhaust valve 7 and the exhaust channel 12 are released into the atmosphere.

When the crankshaft is rotated by an angle of three quarters of a turn until the full turn is completed, the rocker arm DE with respect to the hinge E rotates at a low angular speed (Fig. 1). The rocker arm AB relative to the hinge A, and the connecting rod DK relative to the hinge D rotate clockwise, which reduces the volume of the cavity 8 to a minimum value, provides for forced pushing the remaining exhaust gases through the open exhaust valve 7 and exhaust channel 12 into the atmosphere and the cycle release "of this work cycle.

By the end of the fourth quarter of the shaft revolution, the intake valve 5 relative to the axis of rotation O takes a position on the left, and the exhaust valve 7 takes a position on the right. The rotation of the connecting rod DC relative to the hinge D clockwise leads to the alignment of the cavity 8 with the inlet valve 5. The inlet valve 5 is opened, the cavity 8 is in communication with the atmosphere, the combustible mixture (air from the diesel engine) through the inlet channel 11 and the open inlet valve 5 is let into the cavity 8, and the remaining exhaust gases through the open exhaust valve 7 and the exhaust channel 12 are removed into the atmosphere.

When the shaft is rotated a second revolution, the BS connecting rod relative to the hinge B rotates clockwise, the cavity 8 is displaced outside the exhaust valve 7. The exhaust valve 7 is closed, the “discharge” cycle of this duty cycle is completed in the cavity 8 and the “intake” cycle of the next duty cycle.

The engine with two cavities for the flow of the working cycle contains a fixed crankcase 1, which inside the top contains the head 2 with the spark plug 6 (nozzle at the diesel engine), at the bottom of the head 9 with the spark plug 6 (nozzle at the diesel engine), and in the center there is a coaxially mounted crankshaft shaft with two round cheeks 3 and a connecting rod neck with a hinge K, having an axis of rotation O (figure 5). A connecting rod neck with a hinge K relative to the axis of rotation O is turned to the head 9. The main neck of the crankshaft and the adjacent cheek 3 relative to the axis of rotation O contains an inlet channel 11 with an inlet valve 5 on the left, and an outlet channel 12 with an outlet valve 7 on the right.

Between the cheeks 3 of the crankshaft shaft, the main connecting rod DK is mounted pivotally connected to the connecting rod neck with hinge K and the trailed connecting rod BS is connected to the main connecting rod DK by hinge C. To the hinge B of the connecting rod BS, the rocker arm AB is pivotally connected to the head 2 by hinge A. The rocker arm DE is pivotally connected to the hinge D of the connecting rod DK, which is connected to the head 2 by the hinge E. A spark plug 6 (nozzle at the diesel engine) is installed between the hinges A and E in the head 2. The width of the connecting rods DK and BS, rocker arm AB and DE, the length of the head 2 is equal to the distance between the cheeks 3 of the crankshaft shaft. The inner surfaces of the connecting rods DK and BS, the rocker arm AB and DE, the head 2 and two cheeks 3 of the crankshaft form a closed cavity 8, the volume of which cyclically changes during one revolution of the crankshaft.

Between the cheeks 3 of the crankshaft shaft, a second main connecting rod of the Republic of Kazakhstan is mounted, pivotally connected to the connecting rod of the crank by a joint K, and a trailed connecting rod MN, connected to the main connecting rod of the Republic of Kazakhstan by joint N. A rocker arm PR is pivotally connected to the hinge P of the connecting rod of the Republic of Kazakhstan, which is connected by a hinge P to the head 9. In the head 9, a spark plug 6 is installed between the hinges L and P (nozzle at the diesel engine). The width of the rods RK and MN, rocker PR and LM, the length of the head 9 is equal to the distance between the cheeks 3 of the crankshaft shaft. The inner surfaces of the connecting rods RK and MN, the rocker arm LM and PR, the head 9 and two cheeks 3 of the crankshaft form a lower closed cavity 10, the volume of which cyclically changes during one revolution of the crankshaft. The crankcase 1 is closed on both sides by two end caps 4, which serve as a support for the crankshaft.

At a certain angle to the initial position in the cavity 10, the “compression” of the past working cycle was completed, and the fuel mixture was ignited in it with a spark plug 6 of head 9 (fuel was injected with a nozzle of a diesel engine). The combustion of fuel in the cavity 10 increased the pressure of the gases on the surface of the connecting rods MN and RK, and through them the resulting force is applied to the connecting rod journal with the crank shaft joint K. When the crankshaft is rotated from its initial position clockwise by a certain angle of the first quarter of a revolution, the resulting force from the gas pressure relative to the axis of rotation O has a shoulder, which ensures the appearance of torque on it (Fig. 5).

In the initial position, the intake valve 5 is aligned with the cavity 8 and is open (Fig. 5). The cavity 8 is in communication with the atmosphere only through the inlet channel 11 and the open inlet valve 5. The exhaust valve 7 with the cavity 8 is not aligned and therefore closed.

Under the action of torque, the crankshaft is rotated by a first quarter of a revolution (Fig.6). The LM beam relative to the hinge L rotates with a small angular velocity. The rocker arm PR relative to the hinge P, and the connecting rod MN relative to the hinge M rotate counterclockwise, which increases the volume of the cavity 10 and ensures the timely start of the “expansion” beat in it. The connecting rod RK is shifted to the axis O of rotation of the crankshaft, and the exhaust valve 7 is shifted relative to the axis O of rotation to the lower position, and for a certain angle before the completion of the first quarter of revolution, the cavity 10 is aligned with the exhaust valve 7. The exhaust valve 7 is opened and the cavity 10 is communicated with the atmosphere , which ensures the timely completion of the "expansion" cycle. The exhaust gases that are in the cavity 10 under excess pressure through the open exhaust valve 7 and the exhaust channel 12 are released into the atmosphere, which ensures the timely start of the “exhaust” cycle in it.

Rocker AB with respect to hinge A rotates with low angular velocity. The rocker arm DE relative to the hinge E, and the connecting rod BS relative to the hinge B rotate clockwise, which increases the volume of the cavity 8, creates a vacuum in it, ensures its filling with fresh combustible mixture (air from the diesel engine) through the inlet channel 11 and the open inlet valve 5 and timely start of the “intake” stroke of a new duty cycle. With respect to the axis of rotation O, the intake valve 5 is displaced upward, and the exhaust valve 7 is displaced downward.

When the shaft rotates a second quarter of a revolution, the intake valve 5 relative to the axis O is shifted to the right, and the exhaust valve 7 to the left (Fig. 7). The rocker arm DE rotates with a small angular velocity relative to the hinge E. The rocker arm AB relative to the hinge A, the connecting rod DK relative to the hinge D are rotated counterclockwise. The connecting rod BS is shifted to the head 2 and leads the cavity 8 outside the intake valve 5. The intake valve 5 is closed, the cavity 8 is isolated from the atmosphere and the “intake” cycle is completed in a timely manner. The decrease in the volume of the cavity 8 provides a timely start in her cycle "compression".

When the crankshaft is rotated by a second quarter of a revolution, the rocker arm PR relative to the hinge P is rotated at a low angular speed (Fig. 7). The rocker arm LM relative to the hinge L, the connecting rod RK relative to the hinge P are rotated clockwise, and the connecting rod MN is shifted to the axis of rotation O. The volume of the cavity 10 is reduced, exhaust gases are forced out of it through the open exhaust valve 7 and the exhaust channel 12 into the atmosphere. The rotation of the connecting rod RK relative to the hinge P clockwise and the shift of the inlet valve 5 relative to the axis of rotation O to the right combines the cavity 10 with the inlet valve 5. The inlet valve 5 is opened. The cavity 10 communicates with the atmosphere simultaneously through the open intake valve 5 and the open exhaust valve 7, the remaining exhaust gases from it are removed into the atmosphere. The displacement of the connecting rod MN to the axis of rotation O and the displacement of the exhaust valve 7 relative to the axis O to the left leads to its exit beyond the cavity 10. The exhaust valve 7 is closed and the exhaust cycle is completed in a timely manner in the cavity 10.

Near the end of the second quarter of the revolution in the upper cavity 8, the spark plug 6 of the head 2 ignites the combustible mixture (fuel is injected into the diesel with a nozzle). The combustion of fuel in it increases the pressure of the products of combustion on the connecting rods of the DC and BS, and through them on the connecting rod journal with the hinge K of the crankshaft. When it is rotated through a certain angle of the third quarter of a revolution, the resulting force relative to the axis of rotation O appears a shoulder and, accordingly, a torque moment.

Under the action of torque, the crankshaft is rotated a third quarter of a revolution (Fig. 8). With respect to the axis of rotation O, the intake valve 5 shifts downward and the exhaust valve 7 upwardly. Rocker AB with respect to hinge A rotates with low angular velocity. The rocker arm DE relative to the hinge E, and the connecting rod BS relative to the hinge B rotates counterclockwise, which increases the volume of the cavity 8 and ensures the timely start of the “expansion” beat in it. The shift of the connecting rod DK to the axis O of rotation in combination with the displacement of the exhaust valve 7 above the axis O of rotation lead to its alignment with the cavity 8. The exhaust valve 7 is opened, the cavity 8 is communicated with the atmosphere, which ensures the timely completion of the “expansion” beat and the beginning of the beat "release". The exhaust gases from the cavity 8 through the open exhaust valve 7 and the exhaust channel 12 are discharged into the atmosphere.

The LM beam relative to the hinge L rotates with a small angular velocity. The rocker arm PR relative to the hinge P, and the connecting rod MN relative to the hinge M rotate clockwise, which increases the volume of the cavity 10, ensures that fresh combustible mixture (air from the diesel engine) enters into it through the open inlet valve 5 and the “intake” cycle starts there. When the crankshaft is rotated by a fourth quarter of a revolution, the intake valve 5 relative to the rotation axis O is shifted to the left, and the exhaust valve 7 to the right (Fig. 5). The rocker arm DE rotates with a small angular velocity relative to the hinge E. The rocker arm AB relative to the hinge A, and the connecting rod DK relative to the hinge D rotate clockwise, which reduces the volume of the cavity 8 and provides for the forced removal of exhaust gases from it through the open exhaust valve 7 into the atmosphere. At the end of the fourth quarter of the crankshaft revolution, the rotation of the connecting rod ДК relative to the hinge Д clockwise in combination with the displacement of the inlet valve 5 to the left of the rotation axis O leads to the alignment of the cavity 8 with the inlet valve 5. The inlet valve 5 is opened. The cavity 8 is communicated with the atmosphere simultaneously through the open intake valve 5 and the open exhaust valve 7 and the remaining exhaust gases are removed from it into the atmosphere. At the end of the fourth quarter of the revolution, the shift of the BS connecting rod to the left of the rotation axis O, in combination with the offset of the exhaust valve 7 to the right of the rotation axis O, leads to the cavity 8 leaving the limits of the exhaust valve 7. The exhaust valve 7 is closed and the “exhaust” cycle is completed in a timely manner in the cavity 8.

Rocker PR relative to the hinge P rotates with a small angular velocity. The rocker arm LM relative to the hinge L, and the connecting rod RK relative to the hinge P rotate counterclockwise, which reduces the volume of the cavity 10. The displacement of the connecting rod MN to the head 9 leads the cavity 10 outside the intake valve 5. The intake valve 5 is closed, the cavity 10 is isolated from the atmosphere and timely complete the “intake” beat in it. The volume of the lower cavity 10 is reduced, which ensures the timely start of the compression stroke in it. At a certain angle until the complete revolution of the crankshaft shaft in the cavity 10 is completed, the ignition mixture 6 is ignited by the spark plug 6 of the head 9 (fuel is injected with a nozzle of a diesel engine). Combustion products press on the surface of the connecting rods MN and RK, and through them on the connecting rod journal with the hinge K of the crankshaft shaft. At the end of the first revolution of the crankshaft shaft, the “compression” in the cavity 10 is completed.

The rotation of the crankshaft by a certain angle of the second revolution leads to the appearance of a resultant force relative to the axis O of rotation of the shoulder from the pressure of the combustion products in the cavity 10, which ensures that a torque appears on it. Under its action, the crankshaft is rotated by the first quarter of the next revolution (Fig.6). In the cavity 10, the “expansion” cycle of the next working cycle begins, and in the cavity 8, the “inlet” cycle of the next working cycle begins.

The advantages of the proposed engine:

- simplifying the design and reducing the mass of the engine;

- valves operate at lower pressure and lower temperature of the combustion products;

- less power loss on the timing drive and gas exchange;

- lower specific fuel consumption;

- the possibility of further improving specific indicators;

- higher reliability and maintainability.
