Problems solved by technology

Therefore four-stroke internal-combustion engine crankshaft linkage has the following disadvantages: 1. Since the internal-combustion engine utilizes the connecting rod crankshaft to convert the reciprocating motion of the piston into circular motion, when the compression stroke of the cylinder ends, it is at the top dead center of the expansion power stroke. Gas combustion makes the maximum pressure in the cylinder and produces the strongest thrust, but at this time in the crank-link mechanism, the crankshaft and the connecting rod are in a straight line, that is, the force arm is zero, that is, there is no power output at this time, that is, no work is done to the outside; and because The circular motion of the crankshaft will inevitably cause the angle change of the connecting rod connected to the crankshaft, and the power is scattered and only part of the power can be transmitted. Therefore, the crankshaft connecting rod mechanism makes the heat energy utilization rate of the internal combustion engine very low; 2. The direction of the connecting rod and the piston movement exists The angle between the piston and the inner wall of the cylinder block will produce a certain friction force. The larger the angle between the connecting rod and the piston movement direction, the greater the friction force. When the piston runs in the cylinder, the friction force generated by the cylinder wall is uneven. Therefore, after the piston moves at high speed for a long time in the cylinder, it is easy to cause eccentric wear, which will damage the inner wall of the cylinder or the piston and cause air leakage, so that the heat utilization rate of the internal combustion engine will decrease. This is a problem that has not been solved since the use of the crankshaft connecting rod internal combustion engine.
However, at present, the fundamental task of the lubricating oil delivery device for internal combustion engines is to continuously supply lubricating oil with clean, certain pressure and suitable temperature to the friction surfaces of moving parts so that the internal combustion engine can work normally. Therefore, the lubricating oil delivery device for internal combustion engines must have An oil pump with sufficient oil pressure, but there are some problems when using an oil pump in a crankshaft connecting rod internal combustion engine: 1. As a component, the oil pump needs to occupy a certain space in the internal combustion engine, which leads to an increase in the volume of the internal combustion engine. Independent running parts must consume a certain amount of energy; 2. Due to the complex structure of the crankshaft, the lubricating oil needs to be under strong pressure to ensure better lubrication protection for the crankshaft. However, the oil pump generally has low pressure and It is easy to cause the crankshaft to burn or lock the phenomenon, so that the internal combustion engine wears quickly and the life is short; 3. The cost of the oil pump is relatively high. As a necessary part of the internal combustion engine, the manufacturing cost of the internal combustion engine increases
