Abstract
The utility model relates to a gas inlet pipe integrated with an intercooler, which comprises a transition pipe 1, an upper gas inlet cavity 2, the intercooler 3 and a lower gas inlet cavity 4. An inlet of the transition pipe 1 is connected with an outlet of a gas compressor; an outlet of the transition pipe 1 is connected with an inlet of the upper gas inlet cavity 2; and the intercooler 3 is embedded between the upper gas inlet cavity 2 and the lower gas inlet cavity 4. After being pressurized by the gas compressor, outside fresh air enters the upper gas inlet cavity 2 from an outlet of the gas compressor through the transition pipe 1, then enters the intercooler 3 to be cooled and finally enters a cylinder of an engine from an intake manifold of the lower gas inlet cavity 4 to participate in combustion. According to the gas inlet pipe integrated with the intercooler, which is disclosed by the utility model, not only is the arrangement space saved, but also the length of a pipeline from the outlet of the gas compressor to an inlet of a gas inlet passage is greatly shortened, working performance of a supercharged diesel engine is improved, mass of the engine is reduced, the volume of a gas inlet system is also reduced, gas inlet uniformity is improved, and the transient response characteristic of the engine is promoted. Due to pressure stabilizing and filtering effects of a core of the intercooler, the pressure fluctuation in the intake manifold is lower and the gas inlet pipe is more beneficial for improving gas inlet charge and promoting quality of intake swirl.
Description
Technical field
The present invention relates to a kind of engine air inlet tube, be specifically related to a kind of integrated suction tude of intercooler.
Background technique
Modern diesel engine has generally adopted the air intake pressurized technology.The effect of supercharging technology is fairly obvious, and under the certain situation of volume of cylinder, charge density is more big, and the absolute magnitude of fresh air is more big, can spray into more fuel and burn, and starts function to send bigger power.But rising can cause air density to reduce to air through compression temperature in supercharging device, also is that the air density ratio rises less than the rising of pressure ratio, thereby has influenced the performance of pressurized effect.
For strengthening pressurized effect, particularly under the situation of high pressure-charging, will adopt the air inlet cooling method, cold in also namely so-called usually.In cold except can improving charge density, also can corresponding reduction delivery temperature, and also favourable to reducing engine heat load.
Intercooler of the prior art separates with gas handling system, and blower outlet is very long to the pipeline of inlet mouth, has taken very big space, is unfavorable for the layout of other component of motor, also is unfavorable for the installation and removal of gas handling system; And admission space means that greatly the transient response performance of motor descends.
Summary of the invention
The present invention is directed in the prior art gas handling system and take up room too greatly, be unfavorable for the layout of motor miscellaneous part also being unfavorable for the installation and removal of gas handling system, and the technical problem of engine transient bad response, propose a kind of suction tude of integrated intercooler.
Technological scheme of the present invention:
A kind of suction tude of integrated intercooler, comprise transition tube 1, upside air-inlet cavity 2, intercooler 3, downside air-inlet cavity 4, the import of described transition tube 1 is connected with blower outlet, and the outlet of transition tube 1 is connected with the import of upside air-inlet cavity 2, and described intercooler 3 is embedded between upside air-inlet cavity 2 and the downside air-inlet cavity 4.
The import of preferred upside air-inlet cavity 2 is arranged on the middle part of upside air-inlet cavity 2.
The invention has the beneficial effects as follows:
The suction tude of integrated intercooler not only can be saved the engine arrangement space, shorten blower outlet greatly to the pipeline length of inlet mouth, improve the service behaviour of supercharged diesel engine, reduced engine quality, and the gas handling system volume descends, intake uniformity improves, and the transient response characteristic of motor promotes.Because the pressure surge in the voltage regulation filtering effect of intercooler fuse, intake manifold is littler, more is conducive to the improvement of air inlet charge and the lifting of intake swirl quality; The suction tude of integrated intercooler reduces the component of gas handling system, is convenient to installation and removal, can realize quick mounting and dismounting.
Description of drawings
Fig. 1 is the suction tude schematic representation of integrated intercooler;
Fig. 2 is upside air-inlet cavity schematic representation;
Fig. 3 is downside air-inlet cavity schematic representation.
Embodiment
As shown in Figure 1, after the extraneous fresh air supercharging, enter upside air-inlet cavity 2 from blower outlet through transition tube 1, enter intercooler 3 then, in intercooler 3, cool, entered the cylinder participation burning of motor at last by the intake manifold of downside air-inlet cavity 4.
Described upside air-inlet cavity 2 inside arrange upside air-inlet cavity dividing plate, make pressurized air evenly enter intercooler, realize evenly cooling.
Described upside air-inlet cavity dividing plate is arranged on upside air-inlet cavity 2 middle parts, makes pressurized air on average enter left and right sides two-part of intercooler, realizes evenly cooling.
Described downside air-inlet cavity 4 inside arrange downside air-inlet cavity dividing plate, make cooled pressurized air on average enter each cylinder, realize even air inlet, reduce the air inlet nonuniformity of each cylinder.
Evenly cool off and reduce the air inlet nonuniformity of each cylinder for further realization, downside air-inlet cavity dividing plate quantity equates with number of engine cylinders.
Described intercooler preferably adopts the plate and fin type intercooler.
Described transition tube 1, upside air-inlet cavity 2, intercooler 3 is bolted to connection between the downside air-inlet cavity 4.
