The turbosupercharged engine of present stage all has only a gas-entered passageway, and promptly air is through air-strainer, turbosupercharger, and intercooler, intake manifold enters cylinder.No matter which kind of operating mode motor is under, air inlet all must be passed through pressurized machine, intercooler and the pipelines of bending than length more, when hanging down for engine load like this, the interior gas-flow resistance of gas handling system is very big, pumping loss is more, the pressurization gas temperature is higher in addition, makes gas expand, and causes intake efficiency to descend, engine response is relatively poor, pickup lag.
The model utility content
Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide a kind of and can reduce pumping loss and air inlet back pressure, improve intake efficiency, pickup lag when improving the turbosupercharged engine low-load, thereby the gas handling system of the turbosupercharged engine of reduction engine consumption.
For solving above technical problem, the technical solution adopted in the utility model is:
The utility model is a kind of gas handling system of turbosupercharged engine, comprise air-strainer, closure, intercooler, gas exhaust manifold, catalytic converter, turbosupercharger, between described air-strainer and intake manifold bypass line is set, described bypass line is connected with the control valve of its opening and closing of control.
Described bypass line one end is connected on the vacuum tube of air-strainer and turbosupercharger, and the other end of described bypass line is connected the intake valve front end of intake manifold.
On the bypass line that described control valve is arranged on air inlet pipeline behind the air-strainer is connected.
Described control valve is connected with the air inlet pipeline of air-strainer rear end, and control valve is set to the structure of opening or closing according to the vacuum pressure in the air inlet pipeline of air-strainer rear end.
Described control valve is connected with the Engine ECU that the control control valve opens and closes parameter.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Structure of the present utility model can reduce pumping loss and air inlet back pressure, improves intake efficiency, the pickup lag when improving the turbosupercharged engine low-load, the gas handling system of the turbosupercharged engine of reduction engine consumption.

Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment:
As shown in Figure 1, the utility model is a kind of gas handling system of turbosupercharged engine, comprise air-strainer 1, closure 5, intercooler 6, gas exhaust manifold 7, catalytic converter 8, turbosupercharger 9 is provided with bypass line 3 between described air-strainer 1 and intake manifold 4, described bypass line 3 is connected with the control valve 2 of its opening and closing of control.
Described bypass line 3 one ends are connected on the vacuum tube 10 of air-strainer 1 and turbosupercharger 9, and the other end of described bypass line 3 is connected intake valve 5 front ends of intake manifold 4.
On the bypass line 3 that described control valve 2 is arranged on air inlet pipeline 10 behind the air-strainer 1 is connected.
Described control valve 2 is connected with the air inlet pipeline 10 of air-strainer 1 rear end, and control valve 2 is set to according to vacuum pressure unlatching in the air inlet pipeline 10 of air-strainer 1 rear end or the structure of closing.
Described control valve 2 is connected with the Engine ECU that control control valve 2 opens and closes parameter.
As shown in Figure 1, add a triplate line in the pipeline behind air-strainer 1, outlet of triplate line still is connected with turbosupercharger 9, and another outlet links to each other with control valve 2, bypass line 3 couples together control valve 2 and intake manifold 4, guarantees good seal between each interface of whole pipeline.
Figure 2 shows that air flow schematic representation of the present utility model, adopt structure of the present utility model, when motor is in than running on the lower load, control valve 2 makes bypass air inlet pipeline 3 open, fresh that air 11 enters bypass line 3 through air-strainer 1, thereby get around turbosupercharger 9 and intercooler 6, directly enter intake manifold 4, enter cylinder 12 again.This just makes that air inlet is unimpeded, and intake temperature is low, and speed is fast, improves intake efficiency.And bring up to the degree of the parameter that Engine ECU sets when the rotating speed of motor after, control valve 3 is closed bypass line 3, and air 11 enters cylinder 12 through original gas handling system.
The purpose of this utility model is the air inlet pipeline that increases a bypass in original gas handling system, adopt and shorten the air inlet distance, reduce pumping loss and air inlet back pressure, improve the method for intake efficiency, pickup lag when improving the turbosupercharged engine low-load, thus engine consumption reduced.
