Abstract
The invention discloses a throttle valve bypass air supply system which comprises a throttle valve body, wherein an input opening of the throttle valve body is communicated with an air filter by an air inlet pipeline, and an output opening of the throttle valve body is communicated with an air inlet branch pipe by an air delivery pipeline. The throttle valve bypass air supply system is characterized by also comprising a quantitative bypass valve, wherein an air inlet of the quantitative bypass valve is communicated with the air filter, and an air outlet of the quantitative bypass valve is communicated with the air inlet branch pipe. The throttle valve bypass air supply system omits a stepping motor, lowers the production and maintenance costs and the installation difficulty of the throttle valve body, reduces the main body volume of the throttle valve body, reliably realizes the stable control of 50 percent of air flow in the throttle valve body, and has more flexible installation positions of the throttle valve body and the quantitative bypass valve.
Description
Technical field
The invention belongs to the closure supply technology, relate in particular to a kind of throttle valve bypass idling air supply system.
Background technique
At present the closure air supply system of fuel combustion vehicle mostly comprises throttle valve body, as shown in Figure 2: the inlet opening of this throttle valve body communicates with empty filter through air inlet pipeline, the delivery outlet of this throttle valve body communicates with intake manifold through aspirating pipeline, intake manifold is connected on the motor, and the negative pressure that engine operation produced is aspirated the cleaned air in intake manifold, aspirating pipeline, throttle valve body, air inlet pipeline and the empty filter successively.Because motor is at different height above sea level air pressure, under the conditions such as temperature, its idling air compensation is different, therefore, the amount of oxygen that motor needs also has nothing in common with each other, for cooperating engine combustion to need, conventional art is that a stepper motor is installed on throttle valve body, the output shaft of stepper motor is connected with a plug, this plug is installed in the air feed main passage of throttle valve body, stepper motor receives the control of ECU, ECU is according to engine speed, data such as intake manifold suction pressure, judge the idling work situation of motor, the output control signal is given stepper motor, moves to drive plug, realization is finished the air flow control of throttle valve body interior 50% to the control of aperture in the air feed main passage.
The shortcoming of prior art is: each throttle valve body is to a stepper motor will be installed, this has increased the manufacture cost of throttle valve body greatly, also increased simultaneously the volume of throttle valve body, be not easy to the installation of throttle valve body, particularly on the very little motorcycle of installing space, the installation difficulty of long-pending greatly throttle valve body is bigger.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can cancel stepper motor, reduce production costs, reduce the throttle valve body body volume, reduce the throttle valve bypass air supply system of throttle valve body installation difficulty, reliably realize the stable control of 50% air mass flow in the throttle valve body.
For achieving the above object, the present invention explains a kind of throttle valve bypass air supply system, the inlet opening that comprises throttle valve body, this throttle valve body communicates with empty filter through air inlet pipeline, the delivery outlet of this throttle valve body communicates with intake manifold through aspirating pipeline, its key is: also comprise quantitative bypass valve, the suction port of this quantitative bypass valve communicates with described empty filter, and the air outlet of this quantitative bypass valve communicates with described intake manifold.
Throttle valve body is realized the basic air mass flow of motor required 50%, and quantitatively bypass valve is realized the adjustable air flow of motor required 50%.
The automatically controlled input end of described quantitative bypass valve is connected on the ECU.
ECU is according to data such as engine speed, intake manifold suction pressures, judge the idling work situation of motor, ECU output Pulse wave is controlled the break-make of quantitative bypass valve, utilizes the flow of the dutycycle control bypass gas circuit of Pulse wave, realizes the stable control of 50% air mass flow.
The suction port of described quantitative bypass valve is connected on the described empty filter by the road, and the air outlet of this quantitative bypass valve is connected on the described aspirating pipeline by the road.
Remarkable result of the present invention is: a kind of stepper motor of having cancelled is provided, reduce production costs, reduce the throttle valve body body volume, reduce the throttle valve bypass air supply system of throttle valve body installation difficulty, reliably realize the stable control of 50% air mass flow in the throttle valve body.The mounting point of throttle valve body and quantitative bypass valve is more flexible, has reduced the system maintenance cost.

The automatically controlled input end of described quantitative bypass valve 6 is connected on the ECU7.
The suction port of described quantitative bypass valve 6 is connected on the described empty filter 3 by the road, and the air outlet of this quantitative bypass valve 6 is connected on the described aspirating pipeline 4 by the road.
Its working principle is:
ECU is according to data such as engine speed, intake manifold 5 suction pressures, judge the idling work situation of motor, ECU output Pulse wave is controlled the break-make of quantitative bypass valve 6, utilizes the flow of the dutycycle control bypass gas circuit of Pulse wave, realizes the stable control of 50% air mass flow.
Although above structure is described the preferred embodiments of the present invention in conjunction with the accompanying drawings; but the invention is not restricted to above-mentioned embodiment; above-mentioned embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite of aim of the present invention and claim; can make multiple similar expression; as the suction port of changing quantitative bypass valve 6 is connected with air pipe 2; the air outlet is connected with intake manifold 5; by modes such as other single chip circuit controls, such conversion all falls within protection scope of the present invention.
