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 engine exhaust by-pass collar 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, motor, engine exhaust pipe, turbine, turbine steam outlet pipe, coupling shaft, first connecting tube, second 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, moving body 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 motor is connected with the air outlet of engine air inlet tube, the suction port of engine exhaust pipe 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 two ends of first connecting tube are connected with turbine steam outlet pipe, cavity volume left side wall respectively; The two ends of second connecting tube are connected with engine exhaust pipe, cavity volume left side wall respectively, and 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 is one, and moving body is installed in the cavity volume; Moving body contacts with the internal face sealing of cavity volume, and moving body is connected with the cavity volume upper wall surface through elastic member.The cross section of cavity volume is a rectangular, and elastic member is a spring.
In working procedure of the present invention, moving body can move up and down in cavity volume.When motor is in high-speed working condition; The engine exhaust pipe internal pressure is higher; Moving body moves up and pressure elasticity parts upwards, and a part of exhaust in the cavity volume flows in the turbine steam outlet pipe through first connecting tube, thereby makes the acting ability drop of turbine; The air inflow of motor reduces relatively, and each cylinder detonation pressure reduces; When motor is in the low speed operating mode; The engine exhaust pipe internal pressure is lower, and under the effect of elastic member, moving body moves down; Do not have in the cavity volume in exhaust flows in the turbine steam outlet pipe through first connecting tube; Thereby the acting ability of turbine is strengthened relatively, and the air inflow of motor increases relatively, and each cylinder burning better.
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, each cylinder detonation pressure is lower when high-speed working condition; And cavity volume is away from outlet pipe, and the volume cavity temperature is lower, and the sealing problem between moving body and the cavity volume also solves easily.
