Description
Technical Field
The invention belongs to the field of engines, and particularly relates to an engine.
Background
The internal combustion engine is characterized in that fuel is instantaneously combusted in a closed space formed by a cylinder barrel, a cylinder cover and a piston, the piston is pushed by generated high-pressure and high-temperature gas to realize the conversion of internal energy into kinetic energy, the basic structure of the internal combustion engine is shown in figure 1, wherein A shows an air inlet valve, a rocker arm and a spring; b represents a valve cover; c represents an air inlet; d represents a cylinder head; e represents a cooling liquid; f represents an engine block; g denotes an oil pan; h represents an oil groove; i represents a camshaft; j represents exhaust valve, rocker arm and spring; k represents a spark plug; l represents an exhaust port; m represents a piston; n represents a connecting rod; o represents a connecting rod bearing; p denotes a crankshaft. In order to meet three conditions of fuel, oxygen and ignition point required by combustion, an internal combustion engine is a working cycle through four strokes of air suction, compression, work application and exhaust. One working cycle crankshaft rotates for two circles, and the power stroke finishes one-time energy conversion. Note that the crankshaft and piston are connected together by a connecting rod, and the two components operate synchronously. When the crankshaft is at the top dead center or the bottom dead center, the piston is synchronously at the top dead center or the bottom dead center, and the forces applied to the two ends of the connecting rod are equal.
Briefly described, the work process of an existing internal combustion engine:
1) and in the air suction stroke, the crankshaft rotates under the action of external force inertia, the piston is driven to move downwards from the top dead center, the air inlet valve is opened, the air and fuel mixed gas (only air is sucked by the diesel engine) is sucked until the bottom dead center, the air inlet valve is closed, and the air suction stroke is finished.
2) And in the compression stroke, the crankshaft rotates under the action of external force inertia, the piston is pushed to move upwards from the bottom dead center to compress sucked gas until the top dead center, and the compression stroke is finished.
3) The working stroke is that the crankshaft rotates, the piston is at the top dead center position, the fuel is in a closed and narrow compression space, the fuel is instantly combusted to generate high-pressure and high-temperature gas to push the piston to move downwards, the piston converts the downward thrust into the rotating force of the crankshaft through the connecting rod to be output outwards until the bottom dead center, and the working stroke is finished.
4) And in the exhaust stroke, the crankshaft rotates under the action of external force inertia, the piston is pushed to move upwards from the bottom dead center, the exhaust valve is opened to exhaust waste gas generated by combustion until the top dead center, the exhaust valve is closed, and the exhaust stroke is ended.
In the working stroke, the piston reciprocates in the cylinder, and the crankshaft rotates around the main journal and the connecting rod journal. Analyzing the power stroke:
when the power stroke begins, the piston and the crankshaft are synchronously at the top dead center position, the upper end of the piston is a closed and narrow compression space, at the moment, fuel is instantaneously combusted, high-pressure and high-temperature gas is generated, and the piston is pushed to move downwards. When the gas pushes the piston to move downwards, the closed space at the upper end of the piston is increased, the gas expands, the pressure is reduced, and the thrust on the piston is continuously reduced.
When the power stroke starts, the crankshaft is at the top dead center position, the central point of the crankshaft main journal, the central point of the connecting rod journal and the central point of the piston pin are on a vertical line (the straight line of the cylinder barrel central point and the crankshaft main journal central point), at the moment, the upper end of the piston is in a closed and narrow compression space, fuel is combusted instantly, the pressure of generated gas is highest, and the thrust to the piston is also maximum. On the contrary, because the three points of a central point (the central point of a main journal of the crankshaft), a rotating point (the central point of a connecting rod journal) and a thrust point (the central point of a piston pin) are on a vertical line, the conversion efficiency of the crankshaft to the maximum thrust is zero (the crankshaft cannot convert the maximum thrust into rotary power for output). And as the crankshaft rotates along with the continuation of the power stroke, a central point, a rotating point and a thrust point form a triangle. The central point and the rotation point of the crankshaft form a change of power in the lever rotation process, namely the change of the conversion efficiency of the crankshaft in the power stroke to the pushing of the piston.
From the above analysis, it is known that, in the power stroke of the internal combustion engine in the prior art, the thrust of the gas to the piston is a decreasing change process from large to small, and the conversion process of the crankshaft to the thrust is a conversion process from small to large to small. In this case, it is found that the maximum thrust cannot obtain the maximum efficiency. At present, in order to obtain larger power output in the prior art, technologies such as supercharging, supercharging intercooling, four-valve, direct injection in a cylinder, variable compression ratio and the like are generally adopted, and only the air inflow of an air suction stroke is increased, so that the pressure (thrust) of a power stroke is increased, the air inflow is continuously increased, the energy loss of a compression stroke is inevitably increased, and the conversion efficiency of a crankshaft is not increased.

The working principle of the inertia electric-driving piston lever efficient engine is as follows:
1) the engine rotates, the crankshaft drives the piston to move downwards from the top dead center, and simultaneously, the top piston starts to be accelerated to push towards the near-end position under the action of the cam mechanism. At this time, the gas in the compression cylinder is accelerated to a near end position (the power required by the top piston to push from the far end to the near end position comes from the inertia of the first inertia flywheel disc and the second inertia flywheel disc) when the local piston runs downwards to form a certain angle (for example, rotates to 32 degrees) on the crankshaft.
2) A high-pressure and closed compression space is formed between the piston and the top piston, the electric heating device heats instantly, and high-pressure gas expands (the top piston keeps the position unchanged under the action of the cam mechanism) to accelerate and push the piston to move towards a bottom dead center (a crankshaft has an angle, and the principle of lever rotation power size change is adopted). At the moment, the lever efficiently converts the thrust of the piston into the rotary power of the crankshaft, the rotary power of the crankshaft drives a cam shaft of a cam mechanism to rotate through a gear set, a first-stage speed change large gear drives a first-stage speed change small gear, and a first inertia flywheel disc accelerates to rotate and stores energy (similarly, a second-stage speed change large gear drives a second-stage speed change small gear and a second inertia flywheel disc accelerates to rotate and stores energy) for pushing a top piston to accelerate from a far end to a near end so as to compress gas in a cylinder.
3) The piston moves to a bottom dead center position under the pushing of high-pressure gas expansion, meanwhile, the top piston is driven by the cam mechanism to return to a far end from a near end in an accelerating mode and keep the position unchanged, the inner space of the cylinder barrel is increased, cooling liquid cools gas, air pressure is reduced, and the piston moves to the top dead center position under the driving of the crankshaft.
The said process is completed in one work cycle, the said crankshaft rotates one circle, the said piston reciprocates twice, one return stroke and one power stroke. The power stroke outputs once kinetic energy outwards.

When the top piston is pushed to the near end position, the electric heating device increases the heating temperature, the temperature of compressed gas, the pressure of the gas and the power output of the engine. During deceleration, in the working cycle of the engine, the temperature of the electric heater is reduced, and the electric control air valve adjusts the air pressure in the cylinder according to the air pressure required by the rotating speed.
