Description
Technical field
The invention belongs to technical field of internal combustion engines, specifically, is a kind of suction tude volume continuous changeable device that can realize the self-control of naturally aspirated engine suction tude volume.
Background technique
Present motor can be divided into naturally aspirated and supercharging type, and wherein supercharging type can be divided into again engine driven supercharging, turbosupercharging and up-to-date complex supercharge.Naturally aspirated does not have pressurized machine, and refer to that air arrives cylinder through air-strainer, closure, intake manifold merely, gasoline is injected directly in intake manifold by oil nozzle.For four cylinder engine, a piston makes a merit four strokes: descending (intake valve is opened, and there is pressure difference, and the mixed gas of air and fuel oil enters cylinder under the effect of pressure difference), up (IC Intake Valve Closes, compressed mixed gas, piston stroking upward is lighted a fire to during peak), it is descending again that (mixture combustion expands, promote piston externally to do work, outputting power), again up (exhaust valve is opened, exhaust).Naturally aspirated just refers in first stroke above, mixed gas carries out air-breathing by the pressure difference of self-assembling formation, and supercharging type just refers to first gas compression, improves pressure and the density of gas, when valve is opened time, the high pressure of depended on pressure difference and gas self is to increase air inflow, improves power.For naturally aspirated engine, variable intake manifold technology is comparatively general.Variable intake manifold, by changing the length of suction tude and sectional area, improves combustion efficiency, make motor when the slow-speed of revolution more steadily, moment of torsion is more sufficient, more smooth and easy during high rotating speed, power is more powerful.In ideal conditions, when speed operation, intake manifold volume is the bigger the better, and when high-speed working condition, intake manifold volume is the smaller the better, and like this at every speed, the charging efficiency of motor is all higher, and performance is all better.
Through existing literature search, find that number of patent application is 20142022823.6, name is called the patented technology of small displacement engine variable intake manifold, provides a kind of technology of exhaust pipe volume two-stage variable, but it can not suction tude volume reality continuous variable.
Summary of the invention
The present invention is directed to above-mentioned deficiency, a kind of suction tude volume continuous changeable device is provided, the continuous variable of suction tude volume can be realized.
The present invention is achieved through the following technical solutions, the present invention includes engine air inlet tube, air filter, closure, motor, engine exhaust pipe, catalysis bag, baffler, first connecting tube, regulate chamber, shifting board, spring, second connecting tube, the air outlet of engine air inlet tube is connected with the intake duct of motor, and the air outlet of engine exhaust pipe is connected with the air outlet flue of motor, air filter, closure is arranged on engine air inlet tube successively, catalysis bag, baffler is arranged on engine exhaust pipe successively, adjustment chamber is rectangular structure, the cross section of shifting board is rectangular, shifting board is arranged in regulate in chamber and seal with the internal face in adjustment chamber and contacts, one end of first connecting tube is communicated with closure rear engine suction tude, the other end of the first connecting tube is communicated with regulating the right wall in chamber, shifting board is connected with regulating the left wall in chamber by spring, one end of second connecting tube is connected with regulating the left wall in chamber, the other end of the second connecting tube and catalysis bag, engine exhaust pipe between baffler is connected.
The invention has the beneficial effects as follows: the present invention is reasonable in design, structure is simple, and suction tude volume can continuous variable, and motor is all better at every speed performance of operating condition.
