Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of air-complementing and pressure-establishing device for vehicle engine, comprise sky filtering system, exhaust-gas turbocharger and ICS intercooler system, ICS intercooler system connects motor, described motor has suction tude and intake manifold, suction tude is connected with ICS intercooler system, described intake manifold is provided with and makes the supercharging device that has required pressure when engine speed moment change can be provided in the engine air inlet tube all the time, and described air-complementing and pressure-establishing device for vehicle engine also comprises the valving of the foundation that can realize pressure.
Valving of the present invention comprises first one-way valve and second one-way valve, described first one-way valve is arranged on the engine intake manifold, second one-way valve is arranged on the connecting pipeline between sky filtering system and the exhaust-gas turbocharger, and described first one-way valve and second one-way valve are along with the variation of engine speed is opened or closed.The present invention comprises that also described supercharging device is made up of the ECU (Electrical Control Unit) of making-up air device and control making-up air device work, and described ECU (Electrical Control Unit) control making-up air device replenishes above the gas of the required spent gas amount of motor proper functioning more than 0.5 times in engine air inlet tube when engine speed moment changes.Among Fig. 1, the selected making-up air device of the present invention is a gas compressor, and according to other mode of executions of the present invention, described making-up air device also can be selected small-sized air compressor or other pressurization and air supplement device efficiently for use.
In order to control the gas flow that making-up air device is replenished accurately in engine air inlet tube, the present invention comprises that also described engine shaft is provided with speed probe, ECU (Electrical Control Unit) is by the described speed probe sense vehicle rotating speed of motor in the process of moving, thereby and changes gas flow that making-up air device replenishes with this in engine air inlet tube and set up pressure in the engine air inlet tube.
The air compensation of the present invention in the unit time changes along with the variation of engine speed, for example: the rotating speed when engine idle is between 800～1000 commentaries on classics, suppose that motor needs the gas flow of 1 unit at this moment, because motor is provided with speed probe, therefore, ECU (Electrical Control Unit) is sensed the tach signal of motor with this, and orders about the gas flow that efficient gas compressor adds to 1.5 units in the engine air inlet tube; And when engine speed when 2000 change, need suppose the gas flow of 2 units, so by the efficient gas compressor of control behind the ECU (Electrical Control Unit) induction generator rotating speed at one time in the gas flow of additional 2.5 units in the suction tude of motor.By that analogy, making-up air device replenishes the gas more than 0.5 times of the required gas flow of motor in engine air inlet tube along with the change of engine speed in the unit time, come build-up pressure with this.
