Description

NOVEL ENGINE

TECHNICAL FIELD

[01] The present invention relates to the technical field of engines, and more particularly, to a novel engine.

BACKGROUND ART

[02] An engine is a machine capable of converting other forms of energy into mechanical energy. The engine was first born in the United Kingdom. The engine is suitable for use in a power generation device, and may refer to the entire machine including a power plant (e.g. a gasoline engine and an aero engine). Types thereof include, for example, internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), etc.

[03] The internal combustion engines are commonly used, and may be divided into single-row and double-row types according to different cylinder arrangements.

Cylinders of a single-row engine are arranged in a row, generally vertically, but in order to reduce the height, the cylinders are sometimes arranged obliquely or even horizontally. Cylinders of a double-row engine are arranged in two rows. If an angle between the two rows is less than 180°, the engine is called a V-shaped engine. If the angle between the two rows is equal to 180°, the engine is called an opposed engine.

Opposed engines are widely studied in foreign countries, including opposed piston engines and horizontally opposed engines, in which most of pistons move up and down or horizontally. The pistons move up and down, which makes the lubrication problem of an upper half part of the engine difficult to solve, and makes the centre of gravity of the engine high. The pistons move horizontally, which makes upper surfaces of the pistons not in contact with lubricating oil, resulting in uneven lubrication of the pistons in the cylinders, and affecting the service life of the pistons.

[04] To this end, a new engine is provided to solve the above problems.

SUMMARY

[05] An object of the present invention is to provide a new engine that solves the problems existing in the prior art.

[06] In order to achieve the above object, the present invention adopts the following 5S technical solution.

[07] A novel engine includes a cylinder block. A fixed plate is fixedly connected to the bottom of the cylinder block. An output gear and transmission gears are connected to the fixed plate through a rotating shaft. Both sides of the output gear are in meshed connection with two transmission gears. A crankshaft is rotatably connected to the fixed plate. A flywheel and a driving gear are respectively fixedly sheathed on an outer side wall of the crankshaft. The driving gear is meshed with the transmission gear.

[08] Pistons are connected to the crankshaft through a linkage mechanism. Cylinders corresponding to the pistons are arranged on the cylinder block. The two corresponding cylinders are communicated with each other. The two corresponding cylinders are arranged in an inverted-V form. A spark plug, an intake valve and an exhaust valve are arranged on the top of the cylinder block.

[09] Preferably, the linkage mechanism includes a connecting rod. A groove is provided on one side of the piston close to the crankshaft. A piston pin is rotatably connected to an inner side wall of the groove. Both the piston pin and the crankshaft are connected to the connecting rod through a rotating sleeve.

[10] Preferably, the number of the transmission gears is twice the number of the output gears.

[11] Preferably, the two crankshafts rotate in the same direction.

[12] Preferably, the flywheel and the driving gear are located on both sides of the fixed plate respectively.

[13] The technical solution provided by the present invention may include the following beneficial effects.

[14] 1. In the novel engine, pistons of the engine move obliquely up and down in a reciprocating way, so that the centre of gravity is low, and the energy transformation ratio is high.

[15] 2. In the novel engine, the engine has the advantage of low vibration of a horizontally opposed engine.

[16] 3. In the novel engine, the pistons of the engine move obliquely up and down in areciprocating way, so that the problem of poor lubrication of the horizontally opposed engine is solved.

[17] 4. In the novel engine, engine cylinders are arranged in an inverted-V form, so that the problem of difficulty in lubricating an upper half part of the engine when cylinders of an opposed piston engine are arranged one above the other is solved.

[18] 5. Inthe novel engine, two pistons are arranged in one cavity, so that the blasting pressure in a cylinder is reduced compared with a single-piston engine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[23] The technical solutions in the embodiments of the present invention will now be described clearly and fully hereinafter with reference to the accompanying drawings.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[24] Referring to FIGS. 1-3, a novel engine includes a cylinder block 1. A fixed plate 2 is fixedly connected to the bottom of the cylinder block 1. An output gear 6 and transmission gears $ are connected to the fixed plate 2 through a rotating shaft 3. Both sides of the output gear 6 are in meshed connection with two transmission gears 5. A crankshaft 15 is rotatably connected to the fixed plate 2. A flywheel 4 and a driving gear 14 are respectively fixedly sheathed on an outer side wall of the crankshaft 15. The driving gear 14 is meshed with the transmission gear 5.

[25] Pistons 10 are connected to the crankshaft 15 through a linkage mechanism.

Cylinders 16 corresponding to the pistons 10 are arranged on the cylinder block 1. The two corresponding cylinders 16 are communicated with each other. The two corresponding cylinders 16 are arranged in an inverted-V form. A spark plug 7, an intake valve 8 and an exhaust valve 9 are arranged on the top of the cylinder block 1.

[26] The spark plug 7, the intake valve 8 and the exhaust valve 9 are all fixed to the top of the cylinder block | and are communicated with the cylinders 16.

[27] The linkage mechanism is mounted on the crankshaft 15 so that the pistons 10 may reciprocate within the cylinders 16 to drive the output gear 6 to rotate.

[28] Further, the linkage mechanism includes a connecting rod 13. A groove is provided on one side of the piston 10 close to the crankshaft 15. A piston pin 11 is rotatably connected to an inner side wall of the groove. Both the piston pin 11 and the crankshaft 15 are connected to the connecting rod 13 through a rotating sleeve 12.

[29] Further, the number of the transmission gears 5 is twice the number of the output gears 6.

[30] Further, the two crankshafts 15 rotate in the same direction. [BI] Further, the flywheel 4 and the driving gear 14 are located on both sides of the fixed plate 2 respectively.

[32] The number of the pistons 10 of the engine is an even number and is not limited to two.

[33] The number of the intake valves 8 and the number of the exhaust valves 9 is also not limited to two.

[34] Inthe novel engine, when the engine is running, the piston 10 reciprocates inside the cylinder block 1, and the piston 10 reciprocates to drive the crankshaft 15 to rotate.

Since the driving gear 14 on the crankshaft 15 is meshed with the transmission gear 5, the transmission gear 5 rotates, and since the transmission gear 5 is meshed with the output gear 6, the piston 10 reciprocates to drive the output gear 6 to rotate rapidly. The pistons 10 of the engine move obliquely up and down in a reciprocating way, so that the centre of gravity is low, and the energy transformation ratio is high. The engine has the advantage of low vibration of a horizontally opposed engine. Meanwhile, the pistons 10 of the engine move obliquely up and down in a reciprocating way, so that the problem of poor lubrication of the horizontally opposed engine is solved. In the novel engine, the engine cylinders 16 are arranged in an inverted-V form, so that the problem of difficulty in lubricating an upper half part of the engine when the cylinders 16 of an opposed piston engine are arranged one above the other is solved.

[35] Inthenovel engine, two pistons 10 are arranged in one cavity, so that the blasting pressure in a cylinder is reduced compared with a single-piston engine.

[36] The above descriptions are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.

Any person familiar with the technical field within the technical scope disclosed by the present invention makes equivalent replacements or changes according to the technical solution and inventive concept of the present invention, which should be covered within the protection scope of the present invention.
