In the technical scheme of the utility model, the bypass pipeline is arranged between the air filter and the intake manifold, and the intake bypass pipeline can be opened and closed by monitoring the air pressure before and after the pressurizing of the engine so as to reduce and avoid the phenomena of poor acceleration performance and throttle response lag, so that the performance of the turbocharged engine is more excellent than a naturally aspirated engine under any working condition.
Description
Technical field
The utility model relates to engine system gas handling system field, and particularly a kind of gas handling system of turbosupercharged engine, this system can promote turbosupercharged engine low speed acceleration performance.
Background technique
Load the motor extensive use of turbo charge system at present, the performance of motor promotes significantly, it is the first-selected engine system of motor car engine, but this motor low speed and load the time acceleration performance on the contrary not as naturally aspirated engine, and there is the lags in response problem, particularly work as this motor and be assembled on the automobile, under the operating mode of city, vehicle can not well be brought into play and power character.Its reason is that pressure booster blower impeller is installed in the admission line, reduced effective air inlet area, and this moment, the pressurized machine working efficiency was very low, and the boost pressure of generation does not reach the negative effect that obstruction produces, and acceleration performance therefore occurred and was inferior to naturally aspirated engine with discharge capacity.
The model utility content
The utility model is in order to solve turbogenerator, and particularly the acceleration performance of the turbogenerator of automobile when low speed and load is not so good as naturally aspirated engine on the contrary, and has the lags in response problem, designs a kind of gas handling system of turbosupercharged engine.
The utility model for realizing the technological scheme that its purpose adopts is: a kind of gas handling system of turbosupercharged engine, comprise air-strainer, be arranged on the turbosupercharger and the intake manifold of enmgine exhaust end, described air-strainer, described turbosupercharger, intake manifold three are communicated with by admission line; Comprise that also by-pass line is communicated with described filter cleaner and intake manifold, the electronics valve is set in described by-pass line, and described electronics valve is only just opened during greater than the air pressure of described admission line at intake manifold one end in the air pressure of described admission line air-strainer one end.
Further, in the gas handling system of above-mentioned a kind of turbosupercharged engine: the control mechanism of described electronics valve comprises first pressure transducer that is arranged on described admission line air-strainer one end and is arranged on second pressure transducer and the control unit of engine of admission line at intake manifold one end that the output terminal of described first pressure transducer and second pressure transducer and described control unit of engine are by communicating to connect.
Further, in the gas handling system of above-mentioned a kind of turbosupercharged engine: described motor is a motor car engine, and the output terminal of described first pressure transducer and second pressure transducer utilizes the CAN of automobile to be connected with described control unit of engine.
Further, in the gas handling system of above-mentioned a kind of turbosupercharged engine: also be provided with intercooler between described turbosupercharger and intake manifold, described turbosupercharger, intake manifold and intercooler are connected by admission line.
In the technical solutions of the utility model, by between air-strainer and intake manifold, being provided with bypass duct, open and close the air inlet bypass line by the gas pressure before and after the monitoring engine booster, be used to reduce and avoid the appearance of acceleration performance difference and throttle lags in response, make the supercharged engine performance can both be better than naturally aspirated engine in any operating mode.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is embodiment's 1 turbosupercharged engine gas handling system schematic diagram.
Among the figure: 1, control unit of engine, 2, pipeline behind the intercooler, 3, intercooler 4, intake manifold, 5, motor, 6, gas exhaust manifold, 7, turbosupercharger, 8, admission line, 9, air-strainer, 10, electronics valve, 11, first pressure transducer, 12, by-pass line, 13, second pressure transducer.
Embodiment
Present embodiment is mainly formed by increase by-pass line 12, turbosupercharger 7, first pressure transducer 11, second pressure transducer 13, electronics valve 10 and control unit of engine 1 (ECU) in original gas handling system.Owing to used pressure signal sensor and electronic bypass valve, the instantaneous pressure before and after the monitoring supercharging is also imported ECU and is judged, solves turbosupercharged engine low speed and quickens slow and power character not as the problem of discharge capacity naturally aspirated engine.The present embodiment scheme is easy to implement, and control is convenient.
The working principle of this control system: generally, pressure is greater than the natural aspiration suction pressure after the supercharged engine supercharging, only when the little load of low speed, because impeller gets lodged in air inlet pipeline, pressure after the supercharging rises very slow, and less than the pressure before the supercharging (being the naturally aspirated suction pressure), pressure transducer records the pressure signal before and after the electronic bypass tube valve, and signal imported ECU, if when recording pressure before less than valve of boost pressure behind the valve, open the electronics valve, the preceding pressure communication of this moment gas handling system and gas compressor, air inlet pipeline shortens, and promotes the air inlet response, the same naturally aspirated engine of working state.When electronic valve behind the door pressure greater than electronic valve in front of the door during pressure, throttle down, air inlet this moment is provided by pressurized machine fully.
Describe in further detail below in conjunction with automobile turbosupercharged engine gas handling system.
With reference to Fig. 1 is turbosupercharged engine gas handling system schematic diagram, compares with typical turbine supercharged engine gas handling system, and this invention has increased by-pass line 12, first pressure transducer 11 and second pressure transducer 13, electronics valve 10 and ECU module 1, easy to implement, control easy.
Its working method is, when vehicle start and when quickening (particularly city operating mode), when motor 5 is in the little load operation of low speed, the boost pressure of turbosupercharger 7 generations this moment improves sluggish, first pressure transducer 11 and second pressure transducer 13 record moment this moment electronics valve 10 front and back pressure respectively, and signal imported ECU module 1, if during the pressure that the pressure that records of second sensor 13 records less than first sensor 11, control with the electronics valve opening the same naturally aspirated engine of intake method this moment by ECU; During pressure that the pressure that records when second sensor 13 records greater than first sensor 11, valve moment closes, and this moment, gas handling system was with the typical turbine supercharged engine.
This advantage of system is to have used pressure signal sensor and electronic bypass valve, instantaneous pressure before and after the monitoring supercharging is also imported ECU and is judged, solve turbocharged engine low speed and accelerate slow and dynamic property not as the problem of discharge capacity NA engine, and the present invention program is easy to implement, and control is convenient.
