Description
Technical field
The utility model belongs to Small Leisure formula racing car professional skill field, relates in particular to the variable resonator system of a kind of air inlet.
Background technique
Intake air resonator is to utilize intake process to have intermittence and periodicity, causes the pressure wave that produces certain amplitude in intake manifold, and this pressure wave is propagated in gas handling system with local velocity of sound and past interflection.If utilize the intake manifold of certain length and diameter and the resonant cavity of constant volume composition Resonance Induction System, and coordinated in the air inlet cycle of its natural frequency and valve, so under motor specific rotation speeds, will be before IC Intake Valve Closes, in intake manifold, produce significantly compressional wave, air-distributor pressure is increased, thereby increase air inflow.
Resonant intake system and variable inlet duct are all to utilize the dynamic effect of suction tude to improve volumetric efficiency.The suction pressure fluctuation causing by being interrupted air inlet is very large on air input of engine by air impact, and the gas handling system parameters such as intake manifold length, diameter can change intake pressure wave.
The racing car of specialty match, according under different racing tracks and different operating mode, can revise accordingly the parameter of motor, and the volume of general air inlet resonant cavity is fixed.But, the engine operation speed range broadness of racing car, in the time that rotating speed is different, desirable air inlet length and the volume of resonant cavity also require difference, general high shorter suction tude for rotating speed, the required admission line of the slow-speed of revolution is longer.
And existing variable resonator system is to make as required a valve in suction tude, by the keying of control valve, select different suction tude or the air flue of different length (for example CN201474808U is the resonator system of similar structure), the rotating speed that adapts to motor with this, raises the efficiency.But the overall structure of this variable resonator system is huge too fat to move, be not suitable in the leisure type racing car of miniaturization and.
For kart, the size of the resonant cavity of motor and the length of intake manifold are determined, also determine so for the equivalent volume of the specific rotation speeds of motor.Racing car is under different rotating speeds condition, and the demand difference of the air inflow to motor, under this demand, if can effectively utilize the pressure wave of suction tude, just can increase impact coefficient, improves torque characteristics.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of air inlet variable resonator system, it is in the case of the resonant cavity size and intake manifold length that do not change existing kart motor, by changing the pressure wave of suction tude, increase impact coefficient, improve torque characteristics.
For solving the problems of the technologies described above, technical solution of the present utility model is:
The variable resonator system of a kind of air inlet, the connecting tube that comprises intake manifold, resonant cavity and intake manifold and resonant cavity are linked together; In this connecting tube, be provided with the regulating valve that can regulate connecting tube internal channel size.
Preferably, described regulating valve comprises that one is arranged on the valve block in connecting tube and can drives the throttling valve pin of this valve block rotation.
Preferably, described throttling valve pin is arranged on connecting tube by bearing and the bearing support being arranged on connecting tube.
Preferably, described valve block is fixedly connected with throttling valve pin by pin.
Preferably, described valve block and throttling valve pin are fixed together by the mode of welding.
Adopt after such scheme, the utility model is in order to increase input stroke coefficient, fully excavate the performance of motor, promote the competitive ability of kart, in the gas handling system of existing mini engine, increased a regulating valve, according to the actual demand of heat, can regulate by regulating valve the angle of valve block and connecting tube internal channel, thereby regulate the air inflow of motor, to increase impact coefficient, improve torque characteristics, heighten engine performance.Also can realize and blocking or open resonant cavity, in the time blocking resonant cavity completely, air-flow will be without resonant cavity, reaches the effect of the equivalent volume that regulates motor resonant intake system, further to adapt to the rotating speed of motor, raises the efficiency.
