Description
Technical field
The utility model belongs to technical field of internal combustion engines, particularly relates to a kind of novel device that improves air-intake of combustion engine.
Background technique
At present, adopt supercharging technology to improve the charge density of internal-combustion engine, become one of the most effective enhancements that improves the diesel engine single-machine capacity.Existing vehicle exhaust gas turbocharger internal combustion engine, the pulse exhaust-gas turbochargers that adopt more, when internal-combustion engine during in middle low speed operating mode, the unexpected bend the throttle of vehicle, because exhaust gas flow can not be brought up to corresponding flow simultaneously and come the drive pressure mechanism of qi, cause air inlet deficiency in the short time, burn deterioration is short of power.Promptly be usually expressed as the driver when middle low speed operating mode, in the time of to put one's foot down, internal-combustion engine needs a period of time just tangible acceleration can be arranged.This reason wherein is exactly because exhaust turbine needs the time (that is, the time that the waste gas flow velocity increases gradually) of a response to improve rotating speed, has so just caused turbo-lag, thereby has caused the internal-combustion engine vehicle acceleration performance of exhaust gas turbocharge relatively poor.
The model utility content
The purpose of this utility model is exactly in order to solve the deficiency of above-mentioned prior art, a kind of novel device that improves air-intake of combustion engine is provided, it can change the combustion position of internal-combustion engine middle-low load, improves the output torque and the acceleration performance of low speed in the motor, reduces the discharge amount of internal-combustion engine simultaneously.
For achieving the above object, the technical solution of the utility model is: a kind of device that improves air-intake of combustion engine, comprise intake manifold and first air-strainer and the turbocharger that set gradually along the airintake direction of air inlet main, the front end of described intake manifold is provided with the jet pump with the turbocharger serial or parallel connection, and jet pump is controlled by ECU.
From the above, owing to be provided with jet pump with the turbocharger serial or parallel connection at the front end of intake manifold, and jet pump is controlled by ECU, so ought be to put one's foot down instantaneous, ECU opens jet pump according to the instant data of the speed of a motor vehicle and operating mode, in suction tude, spray fresh air, increase the air pressure in the intake manifold, improve the volumetric efficiency of quickening in the instantaneous cylinder, thereby improve the combustion position of low speed in the internal-combustion engine, change the problem of low speed acceleration performance difference in the turbocharger, improve the output torque of low speed in the motor, optimize acceleration performance, the booster response time of vehicle is shortened greatly; Simultaneously,, also improved the utilization ratio of fuel, reduced the discharge amount of internal-combustion engine because fuel has obtained abundant burning.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel device that improves air-intake of combustion engine, comprise intake manifold 4 and the first air-strainer 2A and the turbocharger 7 that set gradually along the airintake direction of air inlet main 5, it is characterized in that: the front end of described intake manifold 4 is provided with the jet pump 1 with turbocharger 7 serial or parallel connections, and jet pump 1 is controlled by ECU.
As preferred version of the present utility model, described jet pump 1 is arranged on the inlet end of the first air-strainer 2A.Adopt this mode, the gas of jet pump 1 ejection is purified by the first air-strainer 2A, thereby has realized the utility model purpose preferably.
As another kind of preferred version of the present utility model, described jet pump 1 is in series and is in parallel with the first air-strainer 2A with turbocharger 7, and the inlet end of jet pump 1 is provided with the second air-strainer 2B.This arrangement is arranged between the turbocharger 7 and the first air-strainer 2A outlet of jet pump 1, this can realize the purpose of this utility model equally, for better being moved, internal-combustion engine need the gas of pressurization be purified, so this programme is provided with the second air-strainer 2B at the inlet end of jet pump 1.
As another kind of preferred version of the present utility model, described jet pump 1 is in parallel with turbocharger 7, and the outlet port of jet pump 1 is arranged between turbocharger 7 and the intercooler 8, and the inlet end of jet pump 1 is provided with the second air-strainer 2B.
Adopt parallel way to insert jet pump 1, can avoid the phase mutual interference that might occur between fashionable jet pump 1 of series connection and the turbocharger 7, can better realize the purpose of this utility model; The outlet port of jet pump 1 is arranged on the pipeline between turbocharger 7 and the intercooler 8, the fresh air that jet pump 1 is sprayed compresses the high-temperature gas that with turbocharger 7 to be mixed mutually, thereby on the one hand to the fresh air preheating, also can reduce the temperature of high-temperature gas on the other hand, reduce the load of intercooler 8, in this case, the front end of jet pump 1 also needs to be provided with the second air-strainer 2B air is purified.
As another kind of preferred version of the present utility model, described jet pump 1 is in parallel with turbocharger 7, and the outlet port of jet pump 1 is arranged on the ingress of intake manifold 4, and the inlet end of jet pump 1 is provided with the second air-strainer 2B.
This setup can just be increased to fresh air in the internal-combustion engine when jet pump 1 is opened, has further improved the corresponding speed when vehicle quickens, and has reduced the corresponding time of vehicle.
As the utility model preferred version further, the air intake branch 3 at described jet pump 1 place and the air inlet main 5 at turbocharger 7 places along angle that airintake direction became less than 90 °.
When the angle of air intake branch 3 and air inlet main 5 hour, air-flow in two pipelines can jet mode mix mutually and hold under the arm and wrap up in, reduce the turbulent loss that has caused when wide-angle is mixed, helped the stability of air-flow in the pipeline, and and then improved the combustion performance of motor.
The time that ECU control jet pump 1 opens or cuts out, can preestablish according to laboratory data.When the vehicle accelerator pedal is operated, after ECU detects the fuel-flow control structural change, judge the transient speed and the operating mode of motor, with the preset parameters contrast, jet pump 1 is opened or is closed in decision.
As shown in Figure 1, the gas after incremental enters air inlet main 5 via air intake branch 3, enters intake manifold 4 then, burning is after gas exhaust manifold 6 is discharged motor, thereby changed the problem of low speed acceleration performance difference in the turbocharger, the output torque in the raising during low speed has been optimized acceleration performance.
