Description

The new type pressurized suction tude of Twin channel

Technical field

The present invention relates to a kind of suction tude, belong to engine charge component technology field, refer in particular to a kind of new type pressurized suction tude of Twin channel of the employing duct air intake pressurized that is applicable to motorcycle engine.

Background technique

In order to increase the intake efficiency of motor, on automobile, generally adopt machinery or turbocharging technology, there are the following problems in application for this technology:

1, air intake pressurized systems bulky, production and maintenance cost are more expensive, and working life is relatively short, and after supercharging, gas temperature is high, also needs with cooling pressure limitings such as intercooler, by-pass valves.Because distribution engine is limit, this supercharging mode exposes layout difficulty on motor at motorcycle etc., is difficult to realize.

2, exhaust gas turbine and automobile all directly link with engine speed with mechanical turbine, and the speed range of motorcycle (1500r/min~10000r/min), rotating speed span causes greatly controls difficulty.

3, motorcycle is low at middle and slow speed of revolution stage moment of torsion, and middle high rotating speed stage moment of torsion is large, and in motorcycle engine actual moving process, middle high rotating speed stage air inlet charge can meet user demand, and the weakness of middle and slow speed of revolution stage air inlet charge deficiency is needed improvement badly.

Summary of the invention

The object of the invention is to overcome shortcoming of the prior art with not enough, provide a kind of Twin channel new type pressurized suction tude, this super charge pipe can effectively improve the intake efficiency in motor middle and slow speed of revolution stage, ensures the air inlet charge in high rotating speed stage in motor simultaneously.

To achieve these goals, the present invention realizes according to following technological scheme:

The new type pressurized suction tude of a kind of Twin channel, include body, described body inside includes the air inlet section of front end and the section of giving vent to anger of rear end, described body inside forms the first air inlet pipeline and second air inlet pipeline of interval parallel connection in air inlet section, the first air inlet pipeline confluxes into a pipeline with the second air inlet pipeline in the section of giving vent to anger of body inside, and the first air inlet pipeline is provided with one-way valve, the second air inlet pipeline is provided with ducted fan.

Further, described one-way valve closes the first air inlet pipeline in the time that the body inside section of giving vent to anger air pressure is greater than air inlet section air pressure, conducting the first air inlet pipeline in the time that the body inside section of giving vent to anger air pressure is less than or equal to air inlet section air pressure.

Further, described ducted fan is driven by motor.

Further, the air inlet section of described body is connected with air filter, and the section of giving vent to anger is connected with Carburetor or oil sprayer.

Compared with prior art, its beneficial effect is in the present invention:

The present invention can be good at solving that low cruise stage air-intake negative-pressure in motor is low, the phenomenon of air inlet charge deficiency, improves the intake efficiency of motor, low speed torque and power in increase; Ensure that motor high speed operation phase intake resistance reduces simultaneously, improve intake velocity, ensure enough air inlet charges, thereby effectively ensure the output power of motor.

In order to understand more clearly the present invention, set forth the specific embodiment of the present invention below with reference to brief description of the drawings.

Brief description of the drawings

Fig. 1 is linkage structure schematic diagram of the present invention.

Embodiment

As shown in Figure 1, the new type pressurized suction tude of Twin channel of the present invention, includes body 1, described body 1 inside includes the air inlet section 11 of front end and the section of giving vent to anger 12 of rear end, the air inlet section 11 of body is connected with air filter 2, and the section of giving vent to anger 12 is connected with Carburetor or oil sprayer 3, then is connected with motor 4.

Above-mentioned body 1 inside forms the first air inlet pipeline 5 and second air inlet pipeline 6 of interval parallel connection in air inlet section, the first air inlet pipeline 5 confluxes into a pipeline with the second air inlet pipeline 6 in the section of giving vent to anger 12 of body inside, and the first air inlet pipeline 5 is provided with one-way valve 51, the second air inlet pipelines 6 and is provided with ducted fan 61.Further, described one-way valve 51 closes the first air inlet pipeline 5 in the time that the body inside section of giving vent to anger air pressure is greater than air inlet section air pressure, conducting the first air inlet pipeline 5 in the time that the body inside section of giving vent to anger air pressure is less than or equal to air inlet section air pressure; Described ducted fan 61 is driven by motor.

Working principle of the present invention is as described below:

1, the middle and slow speed of revolution stage: the air pressure of the body inside section of giving vent to anger is greater than the air pressure of air inlet section, now closed check valve, the first air inlet pipeline sealing is obstructed, motor drives ducted fan to produce pressurized air stream, the air inflow of whole gas handling system is provided by the second air inlet pipeline, form duct super charge system, increase actual air inflow;

2, the middle high rotating speed stage: along with engine charge demand rises, the air inflow that ducted fan produces is less than the air inlet demand of motor gradually, the air pressure of the section of giving vent to anger declines gradually, in the time dropping to the air pressure of the section of giving vent to anger and be less than or equal to the air pressure of air inlet section, one-way valve opens, the first air inlet pipeline conducting, simultaneously, motor drives ducted fan to continue to produce air-flow, thereby the air inflow of whole gas handling system is provided jointly by the first air inlet pipeline and the second air inlet pipeline, form Twin channel super charge system, ensured enough air inlet charges.

The present invention is not limited to above-mentioned mode of execution, if various changes of the present invention or modification are not departed to the spirit and scope of the present invention, if within these changes and modification belong to claim of the present invention and equivalent technologies scope, the present invention is also intended to comprise these changes and modification.
