Description
Technical Field
The invention belongs to the technical field of engines, and particularly relates to an integrated linear two-stroke engine.
Background
Currently, the existing engine types are:
1. the traditional crank-connecting rod rotary engine has the advantages that after oil in a combustion chamber of a cylinder is combusted and blasted, force is transmitted through the crank-connecting rod to form reciprocating rotary motion, so that the engine is driven to do work. The problem is that the heat exchange efficiency of the engine is low, the most advanced heat exchange level in the world is about 25% conversion rate at present, and the reason is that when the ignition, combustion and explosion moment of the cylinder is the moment of maximum force, the engine is positioned at the uppermost point of the crankshaft, and the 0-degree is opposite to 180-degree to form straight line opposite impact, so that all thrust cannot be converted into rotary power, and at the moment, a great part of energy is consumed.
2. The triangle engine, also called rotor engine, was invented by german feijia wankel 1954, the efficiency of which can be as high as 50%, but the engine has not been used for a long time because the sealing property of the rotor is not long, and the leakage occurs after a period of use, so the engine has not been applied finally.
3. The engine is characterized in that the left and right cylinders are respectively arranged, when the left side ignites and burns, the left cylinder connecting rod is pushed to move right in a straight line, meanwhile, the right cylinder is compressed and then ignites, and the right cylinder connecting rod is pushed to move left in a straight line, so that the left and right rectilinear motion is carried out, and the thermal efficiency conversion of the engine can reach about 42 percent. However, the engine can not be directly used for pushing equipment such as automobiles and the like because of linear motion, can only be used for a power generation device, converts kinetic energy of the engine into electric energy and then pushes a motor to rotate, and can be applied to other fields. The linear driving is affected by the stroke of the cylinder, and the linear length of the linear driving is not longer than the linear length of the circular arc, so that the arrangement of the generator is greatly limited, the efficiency of the generator is not fully exerted, the electric pulse of the electricity generated by the linear engine is in a peak state, and a stable sine wave cannot be formed in the power generation mode. In addition, the conventional linear engine is essentially a two-stroke engine, exhaust gas in a cylinder cannot be completely discharged, and combustion efficiency is greatly affected.
The patent ZL 201811219449.1 discloses a four-stroke four-cylinder opposite unidirectional rotary engine on 1 month 11 in 2019, which directly pushes a unidirectional wheel to do unidirectional motion instead of directly pushing a crank and a straight line by using a traditional cylinder, namely, a blasting gasoline cylinder is arranged at the left end and the right end, two unidirectional wheels which are opposite in front and back are respectively arranged in the middle, a connecting rod which is up and down (or left and right) is correspondingly arranged in the 180-degree direction of the circumference of the unidirectional wheel to be connected with the left and right cylinders, when the left cylinder is pushed to the right on the upper side of the unidirectional wheel circle, the unidirectional wheel is clockwise rotated to the right, and when the right cylinder is pushed to the left on the lower side of the unidirectional wheel, the unidirectional wheel is clockwise rotated to obtain a rotary motion continuously in one direction, so that the engine solves the problem that the starting point and the straight line are limited by not using a crank shaft, but the cylinder return of the engine is realized by using lateral pushing, the structure has high weight, and the lateral kinetic energy is greatly influenced by the lateral restoring force, and the service life is greatly shortened. More critical is: the structure cannot work at all because the left connecting rod and the right connecting rod are simultaneously arranged on the same pivot on the same one unidirectional wheel, and the two ends of the two connecting rods are respectively fixed at the two ends of the air cylinder.
From the performance point of view, when the crankshaft rotation speed is the same, the working times of the two-stroke engine in unit time is 2 times of that of the four-stroke engine, and theoretically, the power of the two-stroke engine is 2 times of that of the four-stroke engine (but only 1.5-1.7 times of that of the four-stroke engine is actually caused by insufficient combustion, and the equivalent unit fuel efficiency is lower than that of the four-stroke engine), the power of the engine is higher, the dynamic property is better, the vibration of the engine is smaller, the volume is smaller, the weight is lighter, the cost is lower, the quality is more reliable, the failure rate is lower, and the use and the maintenance are more convenient. However, since the two-stroke engine cannot completely exhaust the exhaust gas in the cylinder after the combustion process, the combustion efficiency is greatly affected. The four-stroke engine is wider in practical application, and the reason is that under the condition that the current fuel price is higher and the environmental protection requirement is high, the effect of the four-stroke engine is higher than that of the two-stroke engine in combustion efficiency, and the exhaust emission is smaller, but because the four-stroke engine is more complex in structure, large in size, heavy in weight and higher in manufacturing cost compared with the two-stroke engine, the power is not as high as that of the two-stroke engine, the application range is limited, and the maintenance is more complex.
