Abstract

The invention provides a continuous control mechanism and belongs to the technical field of internal combustion engines. The continuous control mechanism comprises an engine air inlet pipe, an engine, an engine exhaust pipe, connection pipes, internal pipes, an adjustment cavity, a control cavity and a rotation shaft. The adjusting cavity and the control cavity are coaxially connected through the rotation shaft. A baffle is fixedly connected with a rotation body. The left wall of a fixing body is connected with the baffle through a spring. One end of the second connection pipe penetrates through the fixing body to be communicated with the first internal pipe. The other end of the second connection pipe is communicated with the portion, located between a catalysis pack and a silencer, of the engine exhaust pipe. When the engine works at a low speed, the volume of the engine air inlet pipe is large, and when the engine works at a high speed, the volume of the engine air inlet pipe is small. The volume of the engine air inlet pipe can be self-adjusted. The continuous control mechanism is reasonable in design, simple in structure, and suitable for optimization design of naturally aspirated internal combustion engine air inlet systems.

Description

Continuous type control mechanism

Technical field

The invention belongs to technical field of internal combustion engines, specifically, is a kind of continuous type control mechanism 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.
