Abstract
A mechanical adjustment type air intake system in the technical field of internal combustion engines comprises a gas compressor, a turbine, an engine, a connecting pipe, a volume cavity, a moving plate and an elastic component. The cross section of the volume cavity is rectangular, two ends of the connecting pipe are respectively connected with an inlet pipe of the engine and the left wall surface of the volume cavity, and the moving plate is installed in the volume cavity, is in sealing contact with the inner wall surface of the volume cavity and is connected with the upper wall surface of the volume cavity through the elastic component. In the working process of the engine, the moving plate can move vertically in the volume cavity. On a low-speed working condition, the total volume of a rear inlet pipe of the gas compressor becomes small, the inlet pressure is increased, and the charging efficiency of the engine is high; and on a high-speed working condition, the total volume of the rear inlet pipe of the gas compressor is increased, the inlet pressure is reduced, and the detonation pressure of the engine is reduced. The mechanical adjustment type air intake system is reasonable in design, simple in structure and suitable for a turbocharging system of the engine.

Background technique
Along with development of modern society, people require increasingly high to the power character and the Economy of motor.Under the certain situation of discharge capacity, want to improve the output power of motor, effective method just provides more fuel and burns.Provide more fuel to be easy to accomplish through oil nozzle to cylinder, yet the air quantity that is complementary with the fuel quantity that increases will be provided simultaneously, but do not accomplish so easily; Fuel burns under the prerequisite of air quantity deficiency, and firing effect is relatively poor.Certain when fuel injection quantity, when cylinder intake air quantity was big, then burning was better, and oil consumption is lower with discharging.The degree of vacuum that traditional naturally aspirated engine forms in cylinder when relying on piston to move downward fully sucks air, and the air that this traditional mode is difficult to q.s is provided is to support the perfect combustion of fuel.Therefore, the burning that is intended for motor provides enough air, makes the power character and the better economy of motor, and turbocharging technology is being played the part of very important role.But existing turbo charge system all can not be taken into account the high and low rotating speed operating mode of motor preferably.
Retrieval through to the existing technology document is found; Chinese patent ZL200410050996.3; Patent name: the variable modular pulse converter supercharging device of a kind of turbo-charged diesel; This patented technology provides the device of the shared volume continuous variable of exhaust in a kind of outlet pipe, can take into account the high and low rotating speed operating mode of motor preferably; But the variation of exhaust institute volume is to realize through moving up and down of movement rod in its outlet pipe; This just needs to increase the special control mechanism of a cover and controls moving of movement rod; Thereby the more complicated that the pressurization system structure is become, and the sealing of its exhaust piping is also relatively poor under high-temperature condition.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned existing technology, a kind of mechanical conditioning type gas handling system is provided, can take into account the high and low rotating speed operating mode of motor preferably.
The present invention realizes through following technological scheme; The present invention includes: compressor air inlet machine pipe, gas compressor, engine air inlet tube, coupling shaft, engine exhaust pipe, turbine, turbine steam outlet pipe, motor, connecting tube, cavity volume, cavity volume upper wall surface, cavity volume lower wall surface, cavity volume left side wall, the right wall of cavity volume, cavity volume front face, cavity volume rear surface, shifting board and elastic member; Gas compressor links to each other through coupling shaft is coaxial with turbine; The air inlet/outlet of gas compressor is connected with the air outlet of compressor air inlet machine pipe, the suction port of engine air inlet tube respectively; The air inlet/outlet of turbine is connected with the air outlet of engine exhaust pipe, the suction port of turbine steam outlet pipe respectively; The air inlet/outlet of motor is connected with the air outlet of engine air inlet tube, the suction port of engine exhaust pipe respectively; The two ends of connecting tube are connected with engine air inlet tube, cavity volume left side wall respectively; The cross section of cavity volume is a rectangular; Cavity volume upper wall surface, cavity volume lower wall surface, cavity volume left side wall, cavity volume right wall, cavity volume front face, the cavity volume rear surface is fixed be one, seals in the shifting board mounting volume chamber and with the internal face of cavity volume to contact, and shifting board is connected with the cavity volume upper wall surface through elastic member.Elastic member is a spring.
In working procedure of the present invention, shifting board can move up and down in cavity volume.When motor was in high-speed working condition, shifting board moved up and the pressure elasticity parts, and the suction tude total measurement (volume) from the blower outlet to the motor between the inlet increases relatively, thereby the suction pressure of motor is reduced relatively, and the detonation pressure of motor reduces; When motor was in the low speed operating mode, under the effect of elastic member, shifting board moved down, and the suction tude total measurement (volume) from the blower outlet to the motor between the inlet reduces relatively, thereby engine charge pressure is increased relatively, and burning is better, and oil consumption is lower.
Compared with prior art, the present invention has following beneficial effect: the present invention can make that motor burns better, oil consumption is lower when the low speed operating mode, detonation pressure is lower when high-speed working condition; And the volume cavity temperature is lower, and the sealing problem between shifting board and the cavity volume also solves easily.
