Description

Internal combustion engine using Hquid fuel
The subject of the invention is an intemal combustion engine using liquid fuel, used to power vehicles, generators, machinery and other devices which require being driven by an internal combustion engine.
The known internal combustion engines using liquid fuel have at least one cylinder, closed with a shaped combustion chamber, in which a piston is moving, as well as a fuel supply system, cooling system, air intake system, exhaust system, ignition system and a connecting rod and crankshaft mechanism with a drive train system.
These engines occur in single cylinder, multiple inline cylinder, or two cylinders in a V, double V or radial configurations. Cylinder sleeves have principally a circular cross-section with a technological ovality, whereas the pistons which move within them have a shaped bottom and cylindrical guiding jacket. In the piston jacket a connecting rod is placed on a pin, connected with the crankshaft, to transfer the driving force to mechanisms which receive it. The essence of the invention, which is an internal combustion engine using liquid fuel, having an at least one shaped combustion chamber for the movement of at least one piston, as well as a fuel supply system, cooling system, air intake system, exhaust system, ignition system and a connecting rod and crankshaft mechanism with a drive train system, consists of the combustion chamber having a shape similar to a ring fragment and a transverse cross section similar to a rectangle, with arc edges, in which two pistons are placed with an external outline identical to the transverse cross section of the combustion chamber, whereas each piston is connected to the crank of the crankshaft by the piston pin and connecting rod located in the upper zone, whereas in its lower zone it has at least one guiding arm, placed on a connecting pin, the axis of which is placed within the plane passing at approximately half the piston's height.
It is advantageous when the combustion chamber within its upper zone has a head with valve sockets for the air intake system and exhaust system, as well as fuel injector and at least one ignition plug.
It is also advantageous when the crankshaft is connected to a collective drive system.
It is also advantageous when the pistons have sealing elements at the surface in contact with the combustion chamber walls.
It is also advantageous when the pistons have a shaped working area.
It is moreover advantageous, when the engine is a unit of multiple combustion chambers, placed in a line, whereas the connecting rods are connected with the crankshafts located on each side of the engine.
It is moreover advantageous when the engine consists a unit of at least two banks of combustion chambers, located in principle in parallel with each other, whereas the connecting rods on the side of the adjacent bank of combustion chambers are connected with the crankshaft having cranks for the placement of connecting rods of the adjacent combustion chambers.
The use of the solution presented in the invention enables the following technical and utility effects: - obtaining thermal efficiency within the range of 55-65% due to a better use of force created during the combustion of fuel-air mixture in the engine cylinder and a better construction of the piston and connecting rod system.
- increasing the efficiency of the engine by better use of the force created during the combustion of the fuel-air mixture,
- possibility of supplying both with ethyl gasoline and diesel fuel,
- possibility of constructing connecting rod and crankshaft elements with reduced strength parameters, due to lower forces acting the drive transmission system,
- the ability to obtain a higher compression ration,
- the possibility of placing multiple combustion chambers in a single bank,
- the possibility of working in a double bank cylinder configuration (such as e.g. current V configuration).
- the possibility of using in the manufacturing of inline engines, and in sets of at least two inline engines— V configuration,
- the possibility of using a two-stroke or four-stroke power cycle,
- the possibility of using pistons with flat, concave or convex working area,
- the possibility of using supply, timing gear, lubrication and ignition systems from known solutions,
- reduction of valve head dimensions,
- reduction of piston dimensions, in particular its guiding jacket,
- increasing the engine operation stability,
- decreasing the engine vibrations
The subject of the invention, in an example, but not limiting, implementation was presented in diagrams on the figure, where on fig. 1 a cross-section of the engine with a section of the drive transmission system in a plane passing through the combustion chamber axis, on fig. 2 an engine cross-section in an arc plane passing through the combustion chamber axis and perpendicular to the plane within this axis was shown, on fig. 3 the engine was shown in a cross-section perpendicular to the combustion chamber axis, in the A- A cross- section of fig. 1 , whereas on fig. 4 the cross-section of the drive transmission unit in the version with two banks of combustion chambers connected with a joint crankshaft, and on fig. 5 a block diagram of a six-cylinder double-bank engine was shown.
The internal combustion engine using liquid fuel has a shaped combustion chamber 1 for the travel of at least one piston 2, and a connecting rod and crankshaft mechanism 3 with a drive train system, and moreover, not shown on the building, air intake system, exhaust system, ignition system, fuel supply system and cooling system. The combustion chamber 1 has a shape similar to a ring fragment and a transverse cross section similar to a rectangle, with arc edges. Inside the combustion chamber 1 two pistons 2 are placed with the same external outline as the internal cross-section of the combustion chamber 1, Each piston 2 through the pin 4 of the piston 2 and the connecting arm 5 is connected to the crank of the crankshaft 6. The piston 2 in its bottom zone has a guiding arm 7, placed on a mounting pin 8, the axis of which is located within the B-B plane passing at approximately half the piston's 2 height.
The combustion chamber 1 within its upper zone has a head 9 with valve sockets 10 for the air intake system and exhaust system, as well as fuel injector 11 and/or at least one ignition plug 12.
The crankshaft 6 is connected with the collective drive system 13, which through a system of gears and/or chain mechanism and/or belt mechanism is connected through a fly-wheel not shown on the figure with the clutch 14 and with the gear box 15.
On the surface of the jacket the pistons 2 have sealing elements 16, whereas their working area has a shaped, spatial outline 17. There are versions of the construction where the engine is a unit of multiple combustion chambers 1 , placed in a line, whereas the connecting rods 5 are connected with the crankshafts 6 located on each side of the engine.
There are also versions of the design, shown on fig. 4, where the engine consists a unit of at least two banks of combustion chambers 1, located in principle in parallel with each other, whereas the connecting rods 5 on the side of the adjacent bank of combustion chambers 1 are connected with the central crankshaft 6 having cranks for the placement of connecting rods 5 of the adjacent combustion chambers 1.
The engine is working using the known Sabathe thermodynamic cycle. Pistons 2 in the combustion chamber 1 by closing on each other over the trajectory established by the curve of the combustion chamber 1 results in the compression of the combustion mixture.
Sending a spark or exceeding the mixture self-ignition pressure results in ignition and sudden increase of pressure, that is, the power stroke. The reciprocating movement of pistons 2 will be converted into rotary movement by the piston and crankshaft mechanism, and in this form will be transmitted to collective drive mechanism 13 and then in a known form through the clutch 14 and gearbox 15 to the drive mechanism of the vehicle, or to another unit powered by the engine. Subsequently pistons 2 perform a linear movement closing on each other and at an appropriate opening of exhaust valves the exhaust stroke occurs, after which an intake stroke occurs, and then a compression stroke.
In order to ensure stable operation, piston 2 is connected by a guiding arm 7 with a mounting pin 8, which ensures stabilisation of the piston 2 stroke over the curve of the combustion chamber 1.
When the engine consists of a unit of multiple combustion chambers 1 , placed in a row, the connecting rods 5 are connected with the crankshafts 6 with the number of cranks equal to the number of combustion chambers 1.
In versions where the engine is composed of a unit of at least two banks of combustion chambers 1 , located in principle in parallel with each other, the power from the crankshafts placed on the side of the adjacent row of combustion chambers 1 is transferred to a common, central crankshaft.
Each piston at the bottom is mounted on a pin in such a manner, as to minimise its movement, and at the top of the piston a connecting rod is mounted using a piston, which transfers the force to the crankshaft. Thus the force of ignition is used almost doubly to both pistons and crankshafts simultaneously.
The engine may use equipment known from other engines.
