Description

Technical Field

[0001] This invention relates to the field of internal combustion engine technology, specifically to a high-efficiency internal combustion engine with a crankshaft-free flywheel, dual-piston cooperative drive, unequal stroke, and no inertia reset. Background Technology

[0002] Traditional internal combustion engines employ a crankshaft, connecting rod, and flywheel inertial return structure. The piston is restricted to equidistant, symmetrical reciprocating motion, relying on flywheel inertia to complete the cycle. This structure has inherent drawbacks: high-speed rotation of inertial components generates significant energy loss; the high-temperature, high-pressure combustion gases are forced to be exhausted prematurely due to inertial demands, resulting in low energy utilization; and high-speed piston reversal generates wasted reverse work and mechanical impact, leading to a low percentage of effective work and a structural ceiling on thermal efficiency. Existing technologies for improving internal combustion engines primarily focus on optimizing local components, failing to address these core issues at the underlying structural level. A novel internal combustion engine structure is urgently needed to achieve inertial return without reciprocating motion and high energy efficiency. Summary of the Invention

[0003] (I) Purpose of the invention: The present invention aims to overcome the technical defects of existing internal combustion engines and provide a high-efficiency internal combustion engine with non-inertial reset and non-uniform stroke. Through the non-inertial reset structure driven by dual pistons, the asymmetric non-uniform stroke design and the high-temperature water injection secondary power technology, the crankshaft, flywheel and other inertial components are completely eliminated, so as to maximize the effective power ratio and minimize energy loss, thus breaking through the thermal efficiency limit of traditional internal combustion engines. (II) Technical Solution: A high-efficiency internal combustion engine with unequal stroke and no inertia reset, without crankshaft, flywheel, or other inertial components, comprising at least two sets of piston working units, a power output mechanism, a piston reset system, an ignition and valve train system, and a water injection secondary power-cooling system; the piston working unit includes a cylinder block and a piston that slides with the cylinder block, with force transmission structures at both ends of the piston to achieve bidirectional force and bidirectional movement; the power output mechanism includes a power output rack connected to the piston, a power output gear meshing with the power output rack, and a power output disengagement device located between the two, the power output disengagement device being used to control the on / off state of power transmission; the ignition and valve train system is located at the position corresponding to the short end of the piston in the cylinder block, and the water injection secondary power-cooling system is... The cylinder block corresponds to the high-temperature region of the piston's long end power stroke; the pistons of each group of piston power units are mechanically linked through a piston reset system, with the power stroke of one group of pistons driving the reset stroke of another group of pistons; the piston's movement stroke within the cylinder block has an asymmetrical, unequal distance structure, divided into a long end power stroke and a short end reset stroke, with the length of the long end power stroke being much greater than the short end reset stroke; after the piston releases energy and its movement speed drops to an extremely low level at the end of the long end power stroke, it is driven by the piston reset system into the short end reset stroke, where the intake, fuel injection, and combustion chamber sealing preparation processes are completed simultaneously; the ignition and valve train system completes fuel injection and ignition at a fixed point at the end of the short end reset stroke, and the pressure generated by combustion drives the piston to perform the long end power stroke throughout the entire process.(III) Beneficial Effects: 1. This invention eliminates inertial components such as crankshafts and flywheels, and achieves inertia-free resetting through a piston reset system with dual-piston coordinated drive, eliminating energy loss from high-speed rotation of inertial components and significantly improving energy transfer efficiency; 2. Adopting an asymmetrical, unequal-distance long and short stroke design, the long end performs work throughout the entire stroke, while the short end only completes reset and preliminary preparation, increasing the effective work ratio. The high-temperature energy generated by combustion can fully expand and perform work, solving the energy waste problem of premature exhaust in traditional internal combustion engines; 3. The piston enters the reset stroke at a low speed at the end of the power stroke, eliminating the reverse useless work caused by high-speed reverse motion, eliminating mechanical shock, reducing overall engine vibration and noise, and extending the service life of components; 4. The ignition and valve timing system completes low-pressure slow combustion at a fixed point, with stable cylinder pressure changes, no knocking, and no severe pressure shock, reducing the material strength requirements for the cylinder block and piston, making operation safer and more reliable; 5. The water-spraying secondary power cooling system sprays water at specific points in the high-temperature region of the piston's long end power stroke. The volume expansion generated by water vaporization achieves a two-stage power output of primary fuel power and secondary steam power, effectively recovering waste heat, reducing cylinder temperature, and further improving the overall thermal efficiency and output power. 6. The overall structure is simple, with fewer parts, small size, light weight, and low manufacturing cost. The number of piston power units can be flexibly set according to power requirements, and the arrangement direction is not restricted. They can be arranged vertically, horizontally, or at any angle, adapting to various installation spaces, and are compatible with gasoline, diesel, and various combustible liquid fuels, with a wide range of applications.

[0005] Detailed Description of Embodiments: The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. For example... Figure 1As shown, the present invention discloses a high-efficiency internal combustion engine with non-inertial return and unequal stroke, which has no crankshaft, flywheel, or other inertial components. Its core consists of two symmetrically arranged piston working units. Each piston working unit includes a cylinder block 1 and a piston 2 that slides and seals with the cylinder block 1. The piston 2 has force-transmitting bosses at both ends, serving as a force transmission structure for bidirectional force and movement, completely eliminating the unequal-distance limitation of piston movement imposed by the traditional crankshaft. One side of the piston 2 is detachably and fixedly connected to a power output rack 3. The power output rack 3 meshes with a power output gear 4, which serves as the rotational power output end of the entire engine, directly converting the linear motion of the piston 2 into rotational power, eliminating the lateral force loss of a crank-connecting rod mechanism. A power output disengagement device 8 is provided next to the meshing point of the power output rack 3 and the power output gear 4 to cut off the power transmission between them during the piston 2's return phase, avoiding reverse resistance during return and eliminating wasted power loss. An ignition and valve train system 5 is fixedly integrated at the short end of cylinder block 1. This system corresponds to the end of the short-end return stroke of piston 2 and includes an intake valve, exhaust valve, fuel injector, and spark plug. It can complete the entire process of intake, fuel injection, ignition, and exhaust. Fuel injection and ignition are completed at this point, achieving a low-pressure slow combustion mode. A water spray secondary cooling system 7 is provided on the side wall of cylinder block 1 corresponding to the high-temperature area of ​​the long-end power stroke of piston 2. This system is a high-pressure water spray mechanism, and its spray nozzle is used to spray high-pressure water mist into the cylinder during the piston's power stroke. The pistons 2 of the two sets of piston power units are mechanically linked through a piston return system 6. The piston return system 6 is a linkage structure, with its two ends connected to the force transmission bosses of the two pistons 2 respectively. The thrust of the long-end power stroke of one set of pistons 2 directly drives the other set of pistons 2 to complete the short-end return stroke, realizing the coordinated drive and inertia-free return of the two pistons.The complete workflow of this invention is as follows: 1. Lower cylinder work: The lower cylinder piston 2 completes combustion under the coordination of the ignition and gas distribution system 5. The pressure generated by combustion pushes the lower cylinder piston 2 to perform a long-end work stroke. The piston 2 drives the power output rack 3 to move synchronously, and outputs rotational power to the outside through the power output gear 4. In the high-temperature and constant-pressure section of the long-end work stroke of the piston 2, the water spray secondary work cooling system 7 is activated, spraying high-pressure water mist into the cylinder. The water mist vaporizes and expands when it encounters high temperature, pushing the piston 2 to continue to do work, realizing secondary steam efficiency enhancement; 2. Disconnection of transmission: When the lower cylinder piston 2 reaches the end of the long-end work stroke, energy is released, the movement speed decreases, the power output disconnection device 8 is activated, and the power transmission between the power output rack 3 and the power output gear 4 is cut off; 3. Upper cylinder reset: The thrust of the lower cylinder piston 2 is transmitted to the upper cylinder piston 2 through the piston reset system 6, driving the upper cylinder piston 2 to perform a short-end reset stroke. The upper cylinder ignition and valve train system 5 simultaneously completes the preparation processes for intake, fuel injection, and combustion chamber sealing. The upper cylinder piston 2 maintains a low speed when it reaches the end of the short-end reset stroke. 4. Upper cylinder power stroke: The upper cylinder ignition and valve train system 5 completes fuel injection and ignition. The combustion pressure pushes the upper cylinder piston 2 to perform a long-end power stroke. The upper cylinder piston 2 drives the lower cylinder piston 2 to complete the short-end reset stroke through the piston reset system 6. 5. Cyclic alternation: The upper and lower cylinder pistons 2 alternately perform power strokes and coordinate resets through the above steps, forming a continuous power output without interruption. Throughout the process, the ignition and valve train system 5 completes the intake and exhaust, fuel injection, and ignition actions of each cylinder according to the piston movement position, ensuring the orderly operation of the cycle. The piston working unit of the present invention can be increased to three or more groups according to the actual power demand. Multiple groups of piston working units achieve synchronous mechanical linkage through the piston reset system 6. Each group alternates to work and resets in coordination to meet the power output requirements of different scenarios. The layout direction of the whole machine can be flexibly adjusted according to the installation space. It can be positioned up and down, left and right or at any angle, with strong adaptability.
